This invention relates to dump-type vehicles in genera] and, in
particular, to a stone slinger option for such a vehicle.
BACKGROUND OF THE INYENIION
There are various vehicles which are used to carry loads, one of which
5 is the dump truck. A dump truck normally carries particulate material such as
gravel, soil or grain. The vehicle has a dump body which involves a generally
rectangular box pivotally connected to the vehicle chassis or frame. Means, such
as hydraulic cylinder and piston units, are provided to raise the forward end of
the box so that the contents thereof will slide to the rear to exit the box through
10 the tailgate. The tailgate extends across the box and is typically hinged to the
box along an a~is that extends along the top edge of the tailgate. The tailgate
can be locked to the box to prevent inadvertent opening and it can also include
a smaller opening with its own manually openable gate to direct the contents of
the box in a path narrower than the full width of the tailgate. The smaller
15 opening is used when it is desired to feed the box contents to a chute or a
conveyor for movement along a particular path. A dump box can be provided
on a self-propelled vehicle, creating a dump truck, or it can be provided on a
towed vehicle such as a trailer or a rail car.
One particular task commonly performed is the carrying of crushed
2û stone or gravel to a construction site. When residential housing is being
constructed it is normal to provide a base of gravel within the boundaries of the
2 ~ a 2
foundation before the basement floor is poured. Ii~ a multi-unit housing tract
there are many foundations under construction at the same time and very often
a dump truck is unable to back right up to the foundation to deposit its load
within the foundation. Furthermore, gravel is normally placed adjacent the outer
S wall of the i~oundation over and around the weeping tile of the ~ground water
collection system. Again, the dump truclk is often prevented from dumping its
load exactly where it is needed. In such circumstances a "stone slinger" truck is
used to deliver the gravel to the dump site.
A stone slinger has a hopper-like body that carries the gravel and
10 includes a conveyor therebelow that receives the gravel from the hopper body
at a position remote from the dump site and conveys it to the dump site itself
within or adjacent the foundations walls. It can be moved as desired to place
gravel at different spots so that the gravel can be spread more evenly by a gang
of workmen. This way of distributing gravel at the construction site is quite
15 inefficient since workmen must monitor the stone slinger, moving the vehicle as
desired relative to the foundation. The workmen must also spread the gravel
after it has been dumped and they must also move the stone slinger ~rom one
foundation to another after dumping is complete. A stone slinger vehicle is very
specialized and very expensive ~o own, operate or rent.
SIJM~RY OF ~ INVEN~ON
The present invention overcomes the problems of the prior art as
described by providing a stone s]inger directly connected to a common dump
truck so that it is always available whenever it is clesired to dump gravel or other
particulate material at a position remote from the truck. The stone slinger
option involves a frame supporting an endless conveyor belt, a drive for the
conveyor belt, and a pivot mechanism that allows the frame to move between
a stowed position adjacent the vehicle frame and a working position extending
S away from the dump body. The conveyor frame can be directed straight
rearwardly of the vehicle or it can be directed at an angle relative to the vehicle
as convenient. When ~he dump box is raised the smaller opening in the tailgate
is used to direct the contents onto the conveyor ~or transport to the dump site
itself. Additionally, the conveyor frame can be connected to the vehicle frame
10 so that the angle of elevation thereof is adjustable, in the event that there are
differences in elevation between the dump truck and the dump site.
The stone slinger may be built in to the vehicle at the factory or it may
be added to any dump vehicle at a later date. Preferably the dump box will be
raised relative to its normal position so as to provide enough room therebelow
15 for the stone slinger frame. The stone slinger option is not restricted to self-
propelled dump trucks per se. It can be used with towed dump trailers, dump-
type rail cars, or gravity feed type rail cars used to carry grain or coal. All that
is required is power to drive the conveyor belt as it receives the contents of the
vehicle so that those contents can be moved to the desired dump site. When
20 the stone slinger is used with a dump truck or a dump trailer the dump box can
be provided with flow directing walls which cause the contents to flow smoothly
towards the smaller opening in the tailgate. Such walls need not be the full
height of the dump bo~, or they can be pivotable or removable, so that normal
operation of the dump vehicle will not be impaired. During such operation the
stone slinger will remain in its stowed condition unclerneath the dump box and
the full tailgate will be opened for rapid discharge of the box contents.
By providing a stone slinger directly on a dump vehicle the task of
filling foundations becomes almost a one-man job, since an entire work crew and
5 another specialized vehicle is no longer required. The vehicle operator can
con~rol the path that the gravel takes from the vehicle to the dump site and a
fleet of dump trucks can readily complete the provision of gave] to an entire
construction site in much less time than at present. The savings to the
contractor will be great and will more than justify the cost of providing a fleet
10 of trucks with their own stone slingers.
Generally speaking therefore the present invention may be considered
as providing a stone slinger attachment ~or a vehicle having a wheeled, elongated
chassis, a dump body pivotally connected to the chassis, means for pivotally
moving the dump body between a lowered travel position and an elevated dump
15 position, and movable gate means in the dump body, the attachment means
comprising: swing arm means for pivotal connection at one end thereof to the
chassis; elongated frame means pivotally connected at one end thereof to the
other end of the swing arm means; and means for independently moving the
swing arm means and the frame means about respective pivot axes to move the
20 frame means from or to a stowed position adjacent the chassis to or from a
working position extending away from the vehicle, the frame means carrying
independently operable conveyor means for moving material discharged from
the dump body through the gate means to a desired location remote from the
vehicle adjacent the other end of the frame means.

Figure 1 illustrates a dump truck 10 provided with the stone slinger
option 12 of the present invention. The truck 10 inclucles a chassis or frame
20 14 supporting a cab 16 for the motor and the driver, a pair of forward steering
wheels 18 and a tandem set of rear drive wheels 20. A rectangular dump box
22 is pivotally connected at the rear thereof, as at 24, and an elevating device
2 ~ 2
26, such as an hydraulic jack, is provided for elevating the opposite end of the
box 22. All of these components are standard for a dump truck and need not
be described in further detail herein. If onc is dealing with a towed dump
trailer instead of a self-propelled vehicle the major difference would be the
S absence of the cab 10, and the drive train. The frame, dump box and elevating
device would still be provided.
Figures 2, 3 and 4 show other details of the dump truck 10, including
the tailgate 28 which closes the rear opening of the dump box 22. The tailgate
28 is normally pivotally attached at the top and can be locked in its closed
lû position by a pneumatic lock (not shown). When the pneumatic lock is
disengaged the tailgate 2B will swing to an open condition as the dump box is
elevated to allow the contents to discharge from the dump box over the full
width thereof. Also shown in those figures are the rearmost cross-member 30
of the frame 14, the longitudinal rails 32 of the frame 14, and the rails 34
15 extending along the bottom of the box 22.
In order to add the slinger option 12 to a standard dump truck it is
desirable to effect certain modifications to the dump truck to improve ease of
assembly and efficiency of the modified vehicle. One such modi~ication involves
raising the entire dump box by about six inches. After removing the box 22
20 from a standard dump truck a pair of auxiliary frame rails 36 is welded to the
frame rails 32 as best seen in Figures 1, 2 and 3. At the rear end each rail 36
includes a raised portion 38 which mates with a standard pivot lug 40 on the
dump box 22, a pivot pin or shaft 42 extending therethrough to efEect the pivot
connection of the box 22 to the vehicle frame. When the box is in its lowered
condition reach box rail 34 will rest on an auxiliary rail 36 rather than a frame
The tailgate 28 should also be modified to create a narrow central
opening 44 which will allow a narrow stream of particulate material to exit the
5 dump box onto the slinger. The opening 44 is closed by a reciprocable gate 46
guided by side guides 48 and powered by a hydraulic cy]inder and piston
assembly 50. Of course, any type of gate could be used to open or close the
opening 44, the illustrated mechanism being but one example.
Internally, as seen in Figure 4, the box 22 may have a pair of flow
10 directing walls 52 removably or pivotally attached to the box side and end walls
by brackets 54. When the dump truck is not being used as a stone slinger the
walls 52 would be removed or pivoted to one side so that the full width of the
box is available for discharge of the contents thereof. With the walls 52 in
place, the contents of the box ~vill be funnelled towards the s)pening 44 for
15 discharge therethrough when the gate 46 is open.
The stone slinger option of the present invention will now be described
with particular reference to Figures 1, 2 and 5 to 8. This option involves an
elongated truss-like frame 58 having a length about the same as the length of
the box 22. The frame 58 includes end drums 60,62 and intervening spaced
20 apart idler rollers 64 extending across the upper and lower levels of the frame.
An endless conveyor belt 66 extends around the end drums 60962 and is
supported along the frame 58 by the idler rollers 64. Side guides 68 ~Figure 2)
extend along the frame 58 on each side of the upper run of the belt 66 so as
to define a channel for the particulate material to be carried by the belt 66.
The drum 62 is connected to a pulley 70 (Figure 8) which in hlrn is
connected via drive belt 72 to an hydraulic or electric motor 74 contained in the
frame 58. The motor 74 will impart appropriate drive to the belt 66 to move
the upper run thereof in a direction away from the dump box. The drive for
S the belt 66 is conventional and need not be described in -further detail. Any
suitable drive system can be used.
At one end of the rearmost cross-member 30 there is pivotally
connected thereto a swing arm 76 having a height similar to that of the cross-
member 30 and a length sufficient to position the slinger frame 58 adjacent the
10 vehicle frame 14. 1'he pivot or hinge connection 78 is conventional and will
permit pivotal movement of the arm 76 through at least gO and perhaps up to
about 135. A lug 80 on the arm 76 is connected to the rod 82 of an hydraulic
cylinder 84 which in turn is connected to the cross-member 30 to effect pivotal
movement of the swing arm 76.
At its free end the swing arm 76 carries a vertically extending hollow
bushing 86, the lower end of the which extends below the bot$om edge of the
swing arm 76. The bushing 86 bearingly receives a shaft 88 (Figure 6), the
upper end of which carries a large diameter (e.g. 19 inches) sprocket 90 and a
U-shaped yoke 92. The near end of the frame 58 is pivotally connected to the
20 yoke 92 by the pivot pin 94 which also may act as the shaft for the belt drum
60 if the drum 6û is positioned within the yoke as in Figure 1. The other views
show the drum mounted rearwardly of the yoke 92. The frame 58 has limited
vertical pivotal movement capabilities, such movement being provided by a
hydraulic cylinder assembly 96 one end of which is connected to the lower
extension of the bushing 86 and the other end of which is connected to the
frame 58 along the length thereof from the yoke 92.
The swing arm 76 carries a motor 98 which may be hydraulic or
electric. The drive shaft of the rnotor carries a small diameter (e.g. 2 inch)
5 sprocket 100 which connects via chain 102 to an idler sprocket 104 mounted to
one end of a vertical idler shaft 106. The shaft 106 is bearingly mounted on
the swing arm 76 and carries another idler sprocket 108 at the upper end
thereof. The sprocket 104 is preferably about eight inches in diameter while the
sprocket 108 is preferably about two inches in diameter. Sprocket 108 is
10 connected to the sprocket 90 by a chain 110.
The operation of the present invention, once the stone slinger 12 has
been installed on the vehicle is as follows. It will be assumed that the slinger
12 is initially in its stowed position as shown in Figures 2, 5 and 8.
The dump truck 10, loaded with crushed gravel or other particulate
15 material is backed into pOSitiOll in close proximity to a dump site, such as
adjacent the foundation of a newly constructed house. The operator will first
of all operate suitable hydràulic controls, not shown, to actuate the hydraulic
cylinder assembly 84 which will cause the swing arm 76 to rotate about the pivot
connection 78, in turn causing the frame 58 to start to swing away from its
20 stowed position adjacent the vehicle frame 14. During this swinging operation
the motor 98 may be actuated so as to cause the frame 58, via the sprocXets
100, 104, 108 and 90 and the chains 102, 110, to rotate on its shaft 88 relative
to the swing arrn 76. Eventually, the swing arm 76 and the frame 58 will take
up the opposition shown in Figures 1 and 7 with the frame 58 extending
rearwardly from the dump box 22 in a line with the dump site and with the belt
66 positioned below the opening 44 in the tailgate 28. The dump box may then
be elevated and the gate 46 raised to a]low particulate material to discharge
through the opening 44 at a controlled rate onto the belt 66. The belt drive
5 motor 74 is actuated so that the be]t 66 will carry the particulate material from
the material receiving end adjacent the dump box 22 to the discharge end
adjacent the dump site. If the discharge end needs to be raised or lowered for
more accurate deposition of the material such may be accomplished by operating
the hydraulic cylinder assembly 96.
The frame 58 can be rotated relative to the swing arm 76 during the
dumping operation, preferably slowly, by operating the motor 98. In this way
a line, rather than a pile, of material will be created at the dump site.
Once the truck is empty, or the desired amount of material has been
deposited at the dump site, the controls are operated to rotate the frame 58
15 relative to the swing arm 76 and to swing the swing arm 76 relative to the cross-
member 30 so as to move the frame 58 back to its stowed position adjacent the
frame 14. The truck can then go on to another dump site or ~ack to the gravel
pit for another load. Also, if desired7 it can be used as a conventional durnp
truck at any time, with the frame 58 stowed, the flow directors 52 removed or
20 pivoted to one side, and the full tailgate 28 being opened for full discharge as
It is readily seen that the present invention greatly increases the
versati]ity of a standard dump truck and greatly increases the efficiency of the
"stone slinging" operation at a construction site. Fewer people are required to
perform the slinging function and the cost of renting or purchasing dedicated
stone slinging equipment is avoided.
The preferred form of the present invention has been described herein.
It is understood however ~hat many components could be altered by a skilled
S workman without departing from the spirit of the invention. Thus the protection
to be afforded this invention is to be determined from the scope of the claims

You should be familiar with OSHA’s requirements for guardrails so that you can identify locations that need to have guardrails installed and know the critical components of a standard guardrail. Other fall protection systems may be used instead of barriers in many situations, such as personal fall arrest systems or safety nets. If bars are used, remember these guidelines on where and how they should be installed.
First, let’s consider some of the fall hazards that must be guarded:
Ladderways and stairways must be guarded except at the actual point of access. The access point must have a gate or be offset from the opening so no one can walk straight into the hole.
Hatchways and floor openings for chutes must have guardrails or hinged covers.
Any hole in a floor must be guarded with a standard guardrail or cover; this includes skylights. OSHA defines a hole as “a gap or void 2 inches or more in its least dimension in a floor, roof, or other walking/working surface.”
Wall openings or windows must be guarded when there is a drop of 6 feet or more on the other side and the bottom of the door is less than 39 inches from the working surface on your side.
Open-sided floors and platforms 6 feet above the adjacent floor or ground must be guarded.
A standard guardrail will have the following:
A smooth surfaced top rail at the height of approximately 42 inches.
An intermediate rail at about half the height of the top fence.
A four-inch-high toeboard at floor level.
Vertical posts spaced not more than 8 feet apart.
Paneling or screening if materials are piled high enough or close enough to the edge that a toeboard is inadequate.
By properly guarding holes, openings, and open-sided floors, we can eliminate a significant source of potential accidents and injuries. Know when to use fall protection and use it.


To meet the demands of growing urban populations, governments around the world are prioritizing investments in public transit infrastructure, including light rail and regional express rail service. Light rail transit vehicles and regional express trains can move large numbers of people efficiently, and often function as the backbone of urban transportation systems.
To make rail an emissions-free mode of transportation, commuter trains can be powered electrically, through direct contact with overhead, high-voltage lines. However, building the infrastructure to support extensive overhead power lines can be very expensive, and can delay or forestall the development of electrified rail service.
But an alternative approach to electric train design could resolve the challenge. It involves the use of hydrogen fuel cells to generate electricity onboard a train, providing power for propulsion and other critical systems. The application of hydrogen fuel cell technology to railway electrification is informally called, “Hydrail”.


How many beers can you hold? In Las Vegas there is a building it stands thanks to 500,000 bottles of beer. Scott McCombs an entrepreneur designed and built the Morrow Royal Pavilion, the largest building in the world built entirely with a material obtained from glass recycling, the Green Stone.
This palace was declared the largest building in the world set up in recycled material, but what makes it even more original is the source from which the so-called "Green Stone" was obtained, 500,000 bottles of beer collected and recovered from the city premises, hotels and nearby hotels.
Interesting enterprise, designed by the company Realm of Design, attentive to environmental efficiency and committed to the production of green innovations in the construction field. Looking at the outside of the building there seems to be no trace of bottles of beer in the walls.
The Morrow Royal Pavilion it appears completely elegant and the walls are smooth and cared for as if they were built in the most refined of cements. This is because blocks of "Green Stone" were used for the processing.
How is the green stone created?
It is obtained by crushing the glass bottles and combining them with a particular type of ash obtained from a by-product of thermoelectric power plants. Once the compound has been poured into the appropriate molds, this new resistant material with great aesthetic impact is obtained.
The Green Stone it is particularly ecological. In addition to recycling, the material making process has a very low rate of carbon dioxide emissions and other pollutants, it also requires less water consumption than using normal red bricks or ordinary concrete.


Civil Engineering resume templates
Civil Engineering focuses on the construction of tunnels, buildings, roads, bridges, etc. It is also a discipline that has gained a great interest in environmental issues, and this is why now civil engineers have modified their work according to the kind of impact that it may have on the environment itself. Since it is such a broad field of work, you may have to work in something specific such as: environmental engineering, water resources engineering, materials engineering, construction engineering, transportation engineering, etc.
Make sure that you have implemented everything that you have learned during your extensive and intensive training. This will allow you to write a resume that demonstrates your capacity to handle all sorts of assignments that a civil engineer is entitled to do. If you have just graduated, you should apply to jobs that do not demand a lot of responsibilities. You will probably take jobs where all your work is supervised and you will be designed as an engineer in training.
Your education does not end with a bachelor's degree; we recommend that you take some refresher courses. But we also recommend that you obtain a post-graduate degree, it is very helpful to increase your chances to be called for an interview. We will now post a list of some universities that offer a post-graduate degree. We have verified that these universities have a solid program in civil engineering.
- University of Illinois at Urbana-Champaign in Champaign, Illinois (Master's degree in Civil Engineering, Environmental engineering in civil engineering and Environmental Science in civil engineering.)
- Purdue University ( Master's degree in Civil Engineering. There are specialty groups such as Architectural Engineering, Construction Engineering, Environmental Engineering, Geomatics Engineering, Geotechnical Engineering, Hydraulics and Hydrology Engineering, Materials Engineering, Structural Engineering and Transport Engineering.)
- University of Minnesota in Twin Cities in Minneapolis, Minnesota. (It offers graduate degrees in Civil Engineering as well as Geological Engineering)
- University of Washington- Seattle in Seattle, WA ( It offers master's degrees in Construction Engineering, Environmental Engineering, Geotechnical Engineering, Hydrology, Water Resources and Environmental Fluid Mechanics, Structural Engineering and Mechanics and Transportation Engineering.)
- Cornell University in Ithaca, New York. ( It offers a Master of Engineering in Civil and Environmental Engineering or Engineering Management. Other programs allow you to obtain a Master of Science degree and a Doctor of Philosophy degree.)
In your resume, you should include a variety of skills that are related to your profession as a civil engineer. Some of these are:
- Paying attention to detail
- Ability to make decisions clearly and timely.
- Communication skills
- Avid curiosity.
Civil engineers actually work in both public and private sectors. It is important for you to have a broad knowledge about physics, project management, mathematics, design, civil engineering, etc. Civil engineering is divided in several categories such as: coastal engineering, environmental engineering, geotechnical engineering, etc.


China’s plan to build an 8,000+ mile underwater high-speed railway to America is an ambitious project, and one that would require crossing several countries and continents. According to an Industry Tap article, the source of this railway would begin “on the north side of China in Beijing, run through Siberia and travel 125 miles underwater spanning the Bering Strait, then through Alaska and Canada before ending its route in New York City.” Altogether, the trip would take only 2 days.
Although the engineering feat required to accomplish such a project may be decades away, it’s certainly feasible to imagine a time when all major continents are connected by high-speed rail, or perhaps by some kind of advanced system of travel (e.g. Elon Musk’s Hyperloop).
To put things into perspective, consider 2014 as being 1914 in terms of technological progress for the 21st century.

A cost-effective strategy resulted in a dramatic 53% reduction in GHG emissions. Enhancing building energy performance paved the way for converting existing assets into a highly efficient district energy system. The network is now fully compatible with heat recovery technologies and clean electricity sources.
UQTR welcomes 14,500 students a year. Located halfway between Montreal and Quebec City, the university contends with extreme climates, including six months of snowfall annually and extended periods of intense cold.
The university has long been committed to sustainability and operational efficiency. Its facilities and operations team had already maximized the existing systems’ performance by fine-tuning control sequences. The limiting factor? The systems themselves.
Reaching next-level efficiency required rethinking the university’s entire district energy system. However, how could energy be distributed more efficiently across a sprawling campus with 15 pavilions?
UQTR had the ambition and recognized the need for design and implementation support. “A project of this size and this complexity,” explained Luc Biron, UQTR’s Director of Equipment Services, “would have been impossible for us to accomplish with our in-house resources alone.”
UQTR tendered an outcome-based RFP to select a project partner. Rather than specify equipment (the “how”), the university specified outcomes (the “what”) that would best support their strategic goals:
UQTR’s team partnered with Ecosystem, an integrated engineering and construction firm with the expertise to deliver their desired objectives. The two teams collaborated through the entire process: “The key to the project’s success was how our university’s team was consulted for recommendations and fully included in decision-making,” maintained Luc Biron.
When upgrading UQTR’s campus-wide energy distribution system, where was the best place to start? Interestingly, with the individual buildings.
Individual buildings are often overlooked in projects that are focused on the distribution network. However, for the network to operate at peak performance, it is critical that individual buildings are retrofitted to be compatible with a more efficient district energy system.
For UQTR, the key to achieving dramatic results was converting its high-temperature district heating loop to a much lower-temperature loop. The conversion was only possible after the buildings themselves were upgraded to draw less energy from the district system. Upgrades focused on enhancing the buildings’ efficiency and installing local systems for the rare high-temperature needs like humidification. These upgrades set the stage for a remarkably efficient and cost-effective district energy system. This investment in building-level infrastructure will benefit the university for decades to come.
The advantages of converting UQTR’s district heating loop to a lower temperature were threefold:
For greater efficiency, certain buildings were connected to the district heating loop in series: a building with higher temperature heating needs is supplied first, which then feeds into a building with lower temperature heating needs. This results in a lower return temperature, which boosts the performance of the new heat pump.
This whole-campus upgrade was designed to be simpler to operate and maintain. Some of UQTR’s cooling systems, for example, were previously decentralized across the university until a unified cooling system was created so heat could be recovered from most of the campus using a single 200-ton heat pump. These centralized systems, operated from a single point with less equipment to maintain, also generate greater savings.
UQTR has joined other higher education institutions – including the historic campus at Brown University – in transitioning to a low-carbon campus through a district energy upgrade. The newly electrified district system is highly efficient and future-proofed for emerging cleantech.
While leading the way forward, UQTR is also demonstrating that low-temperature district heating loops are viable in any climate. During hot, humid summers and extremely cold winters, if it works at UQTR, it can work almost anywhere.
UQTR is now one of the most efficient universities in the province of Quebec. This district energy upgrade reduced GHG emissions by an impressive 53%, while saving the university 23% on energy costs.
Congratulations to UQTR for receiving two awards for this project:


At WF Meyers, we have adapted our tools to use outside of their traditional quarrying applications. We’ve taken on a range of civil engineering projects in the past. A sample of our work is below:
Bloomington, Indiana Water and Sewer Project
The City of Bloomington, Indiana wanted to build a duct below ground that would house its water and sewer lines. While excavating they ran into solid limestone. Because it was in a residential area with houses and buildings in close proximity, they did not want to use more traditional means of excavation. WF Meyers solved their problem by using a Quarry Machine to cut out limestone. The entire project only took about a week to complete.
I-65 Railroad Bridge Replacement
There was a two track railroad bridge spanning I-65 in southeastern Indiana that needed to be replaced. One of the tracks had to remain open at all times, and the bridge could only be cut at night when there was little traffic. Brown Construction contracted WF Meyers to cut out the track. A Quarry Machine was used to cut alongside one of the tracks, effectively cutting the bridge in half. WF Meyers also develop a complex water catching system so that water used by the quarry machine did not go onto the highway below. The project only took 10 days and allowed the train service remained uninterrupted, one half of the bridge to be replaced, and the tracks re-laid.
New York City Metropolitan Transportation Authority
The Franklin Company called upon WF Meyers to assist in carrying out a complex cutting task for the New York City MTA. The project involved removing concrete over a gas line in a crowded city environment. “WF Meyers came in with the tools that were necessary to cut the thickest of concrete,” said Franklin Company engineer, Robert Laga. “We would work with WF Meyers again in a heartbeat. There was no other way the job could have been completed as effectively and creatively.”
Arkansas Warm Water Discharge Project
Robinson Construction was hired to install duct work for a warm water discharge from a power plant in Arkansas. They built a coffer dam to divert the river water so they could work in the river bed; however they hit solid rock and could not use tradition methods of excavating. WF Meyers stepped in with its Quarry Machine and excavated the rock so that concrete could be poured into the footings for the duct work. WF Meyers completed its portion of the project in a week.

Message of His Excellency Benigno S. Aquino III President of the Philippines On the occasion of the start of the...
President Benigno S. Aquino III will inaugurate the second phase of the Metropolitan Waterworks and Sewerage System’s (MWSS) Angat Water Utilization and Aqueduct Improvement Project (AWUAIP) that will be held at the La Mesa Dam Portal in Quezon City on Tuesday, July 17.
During the inauguration rites, the President will push the ceremonial button located at the Stilling Basin area that will signal the formal launching of the AWUIAP Phase 2.
Built at a cost of P1.3-billion, the AWUAIP Phase 2 involves the construction of a new 9.9 km aqueduct (Aqueduct No. 6) and the rehabilitation of the deteriorated section of Aqueduct No. 5 that will allow the more efficient conveyance of raw water from Angat Dam to the La Mesa and Balara water treatment plants.
The AWUAIP, which consists of three development project phases, aims to recoup losses of 394 million liters of water a day due to leakages.
The first phase, which was completed on February 2006, involved the construction of a 5.5 km by-pass of the deteriorated section of the existing Aqueduct No. 5.
The amount of P1.5-billion was invested for Phase 1 which was financed by the Philippine Government.
The second and third phases include the construction of the 9.9 km. section of Aqueduct No. 6, the rehabilitation of the Aqueduct No.5 and the construction of interconnection facilities. The total investment of P5.2-billion for the AWUAIP was financed thru the Preferential Buyer’s Credit of China Export-Import Bank.
Once completed, the AWUAIP will ensure the safety and integrity of raw water conveyance from Angat Dam to the La Mesa and Balara treatment plants, thus maintaining security of water supply for the MWSS service area covering 12 to 14 million people.
Joining the President will be House Speaker Feliciano R. Belmonte, Jr.; Public Works Secretary Rogelio L. Singson; MWSS chairman Ramon B. Alikpala; MWSS Administrator Gerardo A.I. Esquivel; Manila Water chairman Fernando Zobel De Ayala; and Maynilad Water chairman Manuel V. Pangilinan.


The performance of cooling tower greatly depends upon the water distribution over the fills.Nozzles distribute water evenly through a wide spray angle without any dry pockets. They are lightweight and reduce the frequency of clogging.
The Solid Cone Square Pattern (SCSP) nozzles produce a solid cone spray of water that is distributed in a square pattern onto the fills. These nozzles can be used on new/existing pipe, which may be of MS, PP, PVC or AC pipes.
These nozzles are made out of a basic body of ABS plastics and three different types of nylon inserts and turbulators. The turbulators and orifice when assembled with the ABS body generate three types of nozzles capable of discharging water flow rates ranging from 30 GPM to 120 GPM. Depending upon the selection, each nozzle covers an area of 2'X2' to 4'X4' of tower area. A water flow chart to determine the selection may be provided on request.


Stream discharge is a fundamental measurement in hydrology, yet there is still a high degree of uncertainty, especially when estimating high flows in remote locations. Stream discharge is rarely continuously measured, but rather a rating curve is developed based on an empirical relationship between stream water height (stage) and the volume of water moving per unit time (discharge) across a range of stages, from low baseflow to high storm flows. Rating curve relationships can be difficult to establish for high flow conditions, as site access becomes challenging during turbulent high flow events, and the timing and duration of a high flow event may not allow for manual discharge measurements. This is especially true for storms that are intense and over a short duration, such as occur on Calvert Island, where the Kwakshua Watershed Program is based. We developed and installed an automated system to measure stream discharge automatically and have successfully installed seven stations. Check out this great mini-documentary from Hakai called “Go With the Flow“
How it Works
Stage is measured remotely via submerged pressure transducers, and stream discharge is determined with the salt dilution method which measures the relative dilution of an electrically conductive solution (salt) from the site of injection to downstream. A known volume and concentration of salt solution is added to a turbulent part of the river, the salt is well mixed in the flow, and electrical conductivity is measured downstream. The more dilute the salt solution is downstream (measured by reduced conductivity), the greater the discharge. A detailed description of salt dilution for measuring stream flow can be found here [pdf].
These auto-salt systems were installed and are maintained in collaboration with the Hakai Institute and Hakai Energy Solutions. Each system employs a series of pumps, pressure transducers, automated delivery system and electrical conductivity sensors. A salt solution is delivered to the stream and its relative dilution is measure with conductivity sensors downstream of the deposit site where a characteristic “salt wave” is recorded. The timing, duration, and peak value of the salt wave provide information on streamflow. All of this is done remotely, allowing for an unprecedented collection of discharge measurements, allowing us to build entire rating curves over single storms and rapidly updated curves when they shift due to channel changes.
Some readers may be concerned about the ecological implications of adding salt to a freshwater stream. Sodium chloride (common table salt) is non-toxic to freshwater organisms at the concentrations and exposure times typically associated with salt-dilution measurements. We add 500g of salt to 1000L of stream water when measuring steam flow, or the equivalent of 1 sugar cube to 32 cups of coffee.

In many households, the sewage system relies on gravity to efficiently move wastewater from sinks, bathtubs, and toilets into either the municipal sewer lines or a septic system. However, this gravity-driven system has limitations, particularly when it comes to fixtures situated below the main sewer line or septic tank, such as those in basements. This is where the significance of a sewer ejector pump becomes apparent.
A sewer ejector pump plays a vital role in facilitating the transportation of wastewater from lower-level fixtures to the main sewer line or septic system. However, like any mechanical device, these pumps can experience wear and tear over time, leading to potential malfunctions that may require repair or replacement. Rely on ASAP Plumbing for expert sewer ejector pump services in Phoenix, ensuring the smooth operation of your sewage system.
The Importance of Regular Maintenance

Understanding Sewer Ejector Pumps
Sump pumps are often out of sight and out of mind — until they’re urgently needed. To ensure they’re operational when disaster strikes, consider an annual professional inspection. You can also perform basic checks and tests, especially before a major storm. Clear any debris that might clog the system, inspect electrical and mechanical connections, and pour 2-3 gallons of water into the pit to test the pump’s responsiveness. It should activate and clear the water quickly, without odd noises or vibrations.
How Sewer Ejector Pumps Operate
At ASAP Plumbing, we recognize the importance of a fully functional sewer ejector pump, especially in homes where plumbing fixtures are located below the main sewer line. Here’s a brief overview of their operation:
Sewage collected below the level of the sewer system or septic tank is temporarily stored in a sump basin. When the wastewater in this basin reaches a certain height, it triggers a float mechanism. This, in turn, activates a switch that powers the sewer ejector pump, propelling the wastewater out of the basin and into the sewer system or septic tank. A vent system ensures proper escape of sewer gases, while a check valve prevents backflow into the basin.
The Necessity of Sewer Ejector Pump Repair and Replacement
Several issues can impair the function of a sewer ejector pump, necessitating professional repair or replacement:
- Grease and sludge buildup that hampers wastewater ejection
- Malfunctioning float switches
- Motor defects or inconsistencies
- Electrical issues affecting wiring or connections

Frequent Asked Questions
A sewer ejector pump is a system used when a bathroom, laundry room, or any other type of plumbing fixture is installed below the main sewer or septic line grade. The ejector pump collects sewage from your bathroom fixtures, grinds it up, and pumps it up to the main sewer or septic line. This allows waste to be removed from areas that are lower than the main sewer line.
While both pumps are used to remove unwanted water, they serve different purposes. A sump pump is designed to remove clean ground water from a sump pit to prevent flooding, whereas a sewer ejector pump is designed to handle and transport sewage from a lower level to the sewer line.
Sewer ejector pumps should be inspected annually to ensure they’re functioning correctly. This includes checking for clogs, cleaning vents and air holes, and testing the pump to make sure it activates when the basin is filled with water. It’s also important to check the condition of the check valve and replace it if it’s worn out.
If your sewer ejector pump isn’t working, you should first check the power supply and ensure that the pump is plugged in and the circuit breaker hasn’t tripped. Also, make sure the float switch isn’t jammed or obstructed. If these troubleshooting steps don’t fix the problem, it’s time to contact a professional for assessment and repair, as handling sewage can be hazardous.

Mechanics of Structural Composites
Prof. Ajit Mal
Development of efficient methodologies to determine the presence, location and severity of hidden damage in critical structural components is an important task in the design and construction of structural health monitoring systems in aging as well as new structures. In this study a methodology for automatic damage identification and localization is undertaken. The structure is assumed to be instrumented with an array of actuators and sensors to excite and record its dynamic response, including vibration and wave propagation effects. In the vibrational approach, the data consist of the modal response of the structure produced by the actuators while in the wave propagation approach they are the broadband signals due to ultrasonic waves propagating in the structure. Both types of signals are affected by the presence of defects. To determine the type and location of an unknown defect, a set of damage correlation indices is introduced from the frequency response function (FRF) of the dataset. Using the initial measurements or calculations performed on an undamaged structure as baseline, the damage indices are evaluated from the comparison of the frequency.response functions of the damaged structure. The methods are applied to simple structural models involving beams and plates with defects in the forms of cracks and holes. The relative effectiveness of the methods is examined for a variety of boundary conditions and sensor locations relative to the defects.

THE STORY OF THE BRIDGEWATER CANAL
Our October 2018 talk - reviewed by Mike Chitty
Our Chairman, Brian Doman, spoke to us on 1st October about the history and features of the Bridgewater Canal. It was originally created by Francis Egerton, Duke of Bridgewater, to transport coal from his mines at Worsley to the growing town of Manchester. Before the canal was built, coal had to be transported by packhorse to the navigable River Irwell, and its price in Manchester was 7d/cwt (sevenpence per hundredweight). After it was built, the price dropped to 4d/cwt.
Drainage of the mines had always been a problem, and a long tunnel - Massey's Sough - had been constructed as long ago as 1729 to take the water away. When Francis Egerton went on the Grand Tour, he saw the boats on the Canal du Midi, and had the idea of building navigable channels to transport his coal. He engaged James Brindley to design the Bridgewater Canal, with its associated tunnels and bridges. In 1760 Brindley went to London to obtain Parliamentary approval, taking with him a large piece of Cheshire cheese which he used to demonstrate some of his engineering ideas!
The new canal, which opened in 1763, had to cross the River Irwell. There was already a road bridge, and the canal bridge arches had to be at least as wide and high. Brian showed us a colour drawing of Brindley's aqueduct, and also some photographs of the rock face at Worsley from which the canal emerged. The canal tunnel was 8ft high (4ft above and 4ft below the water level) and very soon a second tunnel had to be built to relieve the traffic congestion. We saw a picture of the 'Packet House' from which passenger boats departed for Manchester (a 3-hour journey) or Runcorn (8 hours). As the photographs showed, the canal water is ochre-coloured owing to the presence of iron ore. We saw a map of the mine workings and tunnels. The layout was very complicated, with different navigable levels underground, connected by an 'inclined plane'. All the loading and moving of the barges would have been done by candlelight.
Brian then took us on a pictorial journey along the canal, looking at some of its other features. We saw a lighthouse (to warn of a sharp right turn), a railway station (Patricroft, from where Queen Victoria and Prince Albert had a canal trip to Worsley Hall), and a video of the very unusual Barton Swing Aqueduct (which replaced Brindley's original bridge when the Manchester Ship Canal was built).
The underground canal at Worsley was only navigable until 1877, but remained in use for drainage until the coal mine closed in 1968. Nowadays the main use of the canal is for pleasure cruising and towpath walking. We saw pictures of the marina at Stretford, converted warehouses, and Greyfriars Quay which handled stone for the Liverpool Docks and Chester Cathedral. We also saw several of Brindley's original bridges which, unusually, are named rather than numbered. Brian explained that a tunnel at Preston Brook links the Bridgewater Canal with the Trent & Mersey Canal.
Brian's talk and pictures brought the story of the canal to life, and no doubt encouraged some of those present to go and take a look for themselves at some of the places featured.

Concrete sidewalks are a popular choice for homeowners and businesses. They are durable, affordable, and can be customized to match your style.
Concrete sidewalks are installed so pedestrians may have a strong, level, and consistent travelling path through the right of way and often through sodden grassy areas. A stone base is commonly specified (though not necessarily required) underneath the sidewalk to provide a firm level surface for concrete placement, drainage, and resistance over time. If the engineer on project plans does not require a stone base, it is often still used to provide a smooth and compactable placement surface.

These highly technical devices use various methods to extract the moisture in waste to leave residual materials for proper disposal. Water makes up a significant portion of waste material. By extracting it, the amount of waste is substantially diminished.
The two processes used to remove water content from waste are thermodynamic and mass transfer phenomena. Both methods employ heat to bring wastewater to the boiling point. The method for producing the heat varies but includes electrical, gas, and steam. The variations in the type of heat also applies to how the heat is applied where come forms use heat transfer, while other methods have an exterior heat source.
The wastewater evaporation extraction process is an answer to the ever-growing restrictions being place on industry by the Environmental Protection Agency (EPA), which sets the percentage of allowable contaminants that can be disposed of in landfills. The more stringent standards and concern for the environment have motivated producers to develop safe, efficient, and cost-effective methods for industries to use to reduce their waste material.
Of the two wastewater evaporator methods, the thermodynamic method has become the most used. The process begins with the feeding of wastewater into the wastewater evaporator, where it is heated to produce vapor that is removed by a blower. The efficiency of this method depends on the type of heating method, which is designed to increase the rate of vaporization and the concentration of the remaining materials.
The mass transfer phenomena method is the continuation of a process that has been used for thousands of years. Wastewater is heated to the boiling point. As the waste material boils, it releases droplets of water that are blow off through a filter designed to trap contaminants and other particulates.
It is very likely that the popularity of wastewater evaporators will rapidly grow in the coming years since they provide a safe, clean, efficient, and economical method for the reduction of the volume of waste material.


We are happy with the recent progress of Defiance Block of Nanny Cay Village. The construction crew has been very busy. Since the last update, they have cast the slab grade beams, then striped all the formwork and have been back-filling to prepare for the steel work on the slab.
Last week they finished all the steel work on the slab and were able to cast the foundation on Friday March 13th. Over the weekend the crew have been working hard by putting up formwork and delivering blocks and building materials. At the beginning of the week they started to put up the block for the first floor walls. We are hoping to have the majority of the first floor block work up by the end of the week.
Visit the Defiance Gallery to see more photos of the construction progress.


Probabilistc Workshop 2017
Probabilistic methods in engineering gain a more and more important part in today’s design of components. The 15th International Probabilistic Workshop will be hold in connection with the 10th Dresdner Probabilistik Workshop. At this workshop, probabilistic methods and probabilistic results of investigations of machine components were presented and discussed during the last 9 years.
Date: 27 – 29 September 2017
Location: TU Dresden, Germany
Safety, reliability and risk are key issues in a world with continuously increasing complexity. So the consideration of safety and risk is a key issue for design and use of civil engineering structures, infrastructure works and machinery. Questions about the analysis and treatment of safety and risk arise, as well as questions about optimal safety levels or about acceptable values. Probabilistic methods in engineering gain a more and more important part in today’s design of components. Beside robustness and sensitivity analysis, the probabilistic engineering approach enables the execution of reliability analyses by considering the uncertainties of the designed components in the product development process. Those interested in structural safety, reliability and sensitivity analysis as well as in broader views on the subject will find appropriate sessions during the workshop. Possible topics include various aspects of structural and mechanical safety, probabilistic material and system description, probabilistic methods, risk assessment for design and use as well as for technical and natural hazards and risk perception.
The following paper will be published at the 15th International Probabilistic Workshop.
Quantification of manufacturing uncertainties for an axial compressor blade in CFD
Any technical application is affected by a range of uncertainties. These can be variations of the environmental conditions, which impact the systems behaviour. But also, the inevitable tolerances of the manufacturing processes involved can have a large impact on the final performance. In turbomachinery CFD, deterministic evaluations are common since a long time, however the uncertainties involved have been neglected. In NUMECA’s FINE™/Turbo a dedicated module for UQ has been developed, which was recently extended to cope with geometrical uncertainties as well. The UQ method adopted uses a non-intrusive probabilistic collocation method, which means that no modifications to the flow solver itself are necessary. To allow for a larger number of concurrent uncertainties, a sparse grid formulation for the collocation points is included as well. Using this methodology, the rotor blade of a transonic axial compressor stage is analysed in detail. The impact of a variety of geometrical deviations on the performance of the compressor is evaluated, along multiple points of the speed line – these are near choke, best efficiency and near stall conditions. Furthermore, both the computational effort and numerical accuracy of the UQ module are assessed as well, showing that an industrial application of such UQ is feasible. Also, an inverse design problem is derived, which allows to calculate the necessary manufacturing tolerances for a required performance variability.

Israel's Civil Administration in the occupied West Bank has approved plans to build a railway line in between Palestinian cities, ignoring popular and official local objections. With 30 stations, 11 branch lines and a total track length of over 473 km, the cost of the project, says Haaretz newspaper, is enormous; the plans alone cost almost $300,000 to prepare.
The railway is intended to connect Palestinian cities with those in Israel, Jordan and Syria. The mountainous terrain means that dozens of bridges and tunnels will need to be constructed.
Right-wing Transportation Minister Yesrael Katz is behind the project. He announced recently that he objects to the establishment of an independent Palestinian state.
Alex Smith, the engineer appointed by the Israeli railway authorities, said that the railway is going to connect Jenin and Nablus with the outskirts of Jerusalem, Hebron and Beersheba. Another track, said Smith, will run the length of the Jordan Valley. All will be interconnected with the current Israeli rail network, even the Gaza Strip.
According to Smith, about 12,000 commuters are expected to use the tracks between Jerusalem and Ramallah in the morning, along with 3,000 between Hebron and Beersheba. The number of commuters is expected to exceed 30 million by 2035.
The railway track in the Jordan Valley will be used for tourism and transferring commuters from the Dead Sea to Eilat or Tiberius. The engineer did not comment on any possible military use of the railway network across and around the occupied Palestinian territories.

I'm trying to find some information on right of ways. I've been looking on the internets but haven't found what I'm looking and was wondering if someone here would know a little something about my question.
3 years ago I bought some land to build a house. At that time I was told there was a right of way:
Completed house 2 years ago:
1 year ago county says it's redoing the road and takes/purchases part of my lot and now that construction has begun:
Yesterday Entergy left a note on my door stating I need to sign an agreement to allow them a 16 foot right of way to relocate lines which would eliminate all trees on the road side. So is there always a right of way that just automatically moves if the road is moved?
