Abstract
A temporary dam system for containing a body of water is provided. The temporary dam system is constructed with a number of dam sections. Each dam section has three or more support devices attached to one or more rigid plates. The support devices consist of a front member, a rear member and a brace in an A-frame structure. The rigid plate is attached to a front surface of the front member of each of the support devices and acts as a structural component of the dam section maintaining the support devices in a fixed lateral position relative to the other support devices. The dam system is constructed by connecting a number of dam sections together to form a continuous wall of rigid plates facing a body of water to be contained. A flexible liquid-impervious membrane is then placed over the rigid plates to contain the water.
Description
-Yage1-WATER CONTAINMEM SYSTEM
Tliis invention is in the field of teniporary water contaittment dams and more particular a portable system that can be assembled into a temporary water contair,tnent dam.
BACKGROUIV'D
Temporary dams or dikes are often needed to hold back water, whether for emcrgency to flood control, water diversion, repairs to structures normally stumund or covered by water such as bridges or batilcs, construction projects, etc. Conventionally, sandbags and earthen benns trre used in theses situations to form dikes to contain the water, however, these methods are time consuming and very labor intensive.
If sandbags are used to build a containment wall or dike, it takes a nuniber of people to fill the individual sandbags and then place them in position in the wall being formed.
Because the sand bags are stacked on top of each other to form the wall, if the wall needs to be relatively high, quite a wide base of sandbags is often needed.
Additionally, not only does it take a lot of labor to fill and place the sandbags, it also takes a lot of labor to deconstruct sandbag walls after it they no longer needed. Especially in emergency situations, it is often hard to prioritize the necessary labor to deconstruct the sandbag wall after a crisis is over. In the case of earthen berms, large machinery is often needed to Pat,re2-eonstnict them and this can be troublesome or even dangerous in the circumstances.
Additiottally, both of these tnethods can involve a relatively high environmental impa,ct.
In the case of sandbags, sand lcft behind from the sandbags can have an environmental impact. In tlie case of eartheii berms, often the dirt for the berm is taken from the site causing an impact on the surrounding environment and often the earthen betm cannot be leveled completed when it is no longer nceded, leaving traces of the berm behind.
Because of the time and labor requirements needed to create a temporary containment wall of sandbags or an earthen berm, a uumber of portable dam devices and systems have been developed for creating teinporary water containment dikes. These devices have been developed to be relativel.y tt-ansportable and quick to set up with less labor required than needed for sandbags or earthen berms. '1'hey typically consist of a framework that can be assembled at a site to create the temporary dam.
1.5 Because of the substantial hydrostatic pressure that can he exerted on these strttctares as a result of them having to hold back a body of water, these systems also have to be sufficiently strong to withstand the force exerted on them by the water.
Additionally.
because they will have to be quickly set up on whatever grottnd surface is present at the site of the body of water, they have to be relative conipact to be transportable and relative z0 quick to set up. These reqttirements have resulted in previous systems heing relatively complicated, consisting of numerous braces, connection points and suppon members.
Especially in the case of lateral support, the previous systems often require quite complex ways of linking the temporary structure to provide lateral support, which oftem involves numerous braces and lateral support members.
Accordingly, there is a need for a portable and temporary dam system that is sufficiently strong to contain a body of water, yet relatively simple, transportable and easy to set up.
S[JM11~tiARY OF TIiE INVENTION
j0 It is an object of the present invention to provide a system and method that overcomes problems in the prior art.
In a first aspect, a temporary dam system for containing water is provided.
The system comprises a plurality of dam sections. Each dam section hasg: at ieast three support devices, each support device having: a front member having a top end, a bottom end and a front surface; a rear member having a top end and a bottom end, the rear member connected at the top end of the rear member to the front member; an adjustable first foot incmber provided on the bottom end of the front member, the first foot member operative to adjust the height of the bottom end of the front member; an adjustable second foot member provided on the bottoni end of the rear member. the second foot member operative to adjust the height of the bottom end of the rear member; and a brace having a first end and a second end, the brace connected at the first end of the brace to the front member and connected at the second end of the brace to the rear member, and at least one rigid sheet attached to each front surface of each front members of each of the at least three support devices, the at least one rigid sheet tnaintaitting the at least three support devices in a fixed, spaced apart reiationship and maintaining the front surfaces of the front members of each of the at least three support devices substantially in a single plan defined by the rigid sheet. The system also has a flexible liquid-impervious membrane substantially placed over the rigid sheets of the dam sections and extending onto a ground surface in front of the dam sections.
to In an aspect, a temporary dam system for containing a body of water is provided. The temporary dam system is constructed with a number of dam sections. Each dam section has three or tuore support devices attached to one or more rigid plates. The support devices consist of a front meniber, a rear member, and a brace in an A-frame structnre.
The rigid plate is attached to a front stuface of the front niember of each of the support devices and acts as a stnictural component of the dam section maintaining the support devices in a fixed lateral position relative to the other support devices.
The dam system is constructed by connecting a number of dam sections together to form a continuous wall of rigid plates facing a body of water to be contained. A
t7exible 2o liquid-impervious membrane is then placed over the rigid plates extending down onto a ground surtace in front of the dam. The membrane stops the water, and the rigid plates supported by the support devices maintain the membrane in place.
PageS-The dam can be broken down for transport by disconnecting the dam sections and then for each dam section, removizig the rigid plate from the support devices. In an a:spect, a top end of the rear member of the suppoi-t devices is releasably connectable to the front meniber and the brace is pivotally connected to both the front member and the rear ritember. This allows the support devices to be further collapsed for transport by disconnecting the top end of the rear member from the front member and pivoting the front member and rear member around the brace so that the front member, brace and rear member all lie adjacent to each other.
A straight datn is not always ideal in every situation. Often, it is desirable to be able to angle the dam so that it can be turned around obstacles, etc. In an aspect, a eorner piece is provided that allows the temporary dam to be tu-ned and angled. The corner piece has a main body in the shape of a truncated isosceles triangle. Flanges angled upwards frnm the main body are attached to the two equal side edges of the main body. By connecting the comer piece between two dam sections, with the flanges connected to support devices on the ends of dam sections, a dam can be angled either towards a body of water being contained or away froni a body of water being contaiuied, depending on whether or not the comer piece is positioned upwards or downwards between the dam sections.
For an evcn greater angle, two comer pieces can be connected adjacent to each other.

Za DETAILED DESCRIPTION OF THE ILLUSTRATED EMODI~1VIElVTS
Fig. i illustrates a support device 100 in accordance with an aspect of the present invention. The support device 100 has a front member 110, a rear tnember 120 and a brace 130.
The front member 110 has a top end 112 and a bottom end 114. The rear member has a top end 122 and a bottom end 124 and the rear member 120 is releasably connectable at the top end 122 to the front member 110. In an aspect, the rear member 120 is releasably connectable to the front member 110 so that the rear member 120 is positioned substantially perpendicular to the front mentber 110, when the rear member to 120 is connected to the front member 110.
The brace 130 and has a first end 132 and a second end 134. The first end 132 of the brace 130 is pivotally connected front member 110 and the second end 134 of the brace 130 is pivotally connected to the rear member 120.
A first foot member 140 and seeond foot member 150 are used to support the front member 110 and rear member 120, respectively, on a ground surface. The first foot member 140 is telescopically and pivotally connected to the bottom end 114 of the front member 110 and the second foot member 150 is telescopically and pivotally connected to the bottom end 124 of the rear member 120.
F140e9-Fig 2 illustrates a front view of the support device 100. A front surface 180 of the front member 110 has a nuniber of slot-shaped apertures 190 provided along a length of the front member 110.
Fig. 3 illustrates a side view of the first foot member 140. First foot member 140 has a foot 142 pivotally attached to a shaft 144 that is sized to slide inside the front member 110 of the support device 100. A series of apertures 146 are provided along the length of the shaft 144. The first foot member 140 is telescopically adjustable relative to the front member 110 by siiding the shaft 144 into the front member 110 of the support device, the to shaft 144 can then be slid inside the front member 110 until the first foot member 140 is set at the desired height, Ihen a pin (not shown) can be inserted through an aperture 116 provided at the bottom end 114 of the front member 110 and through one of the series of apertures 146 running along the length of the shaft 144.
Fig. 4 illustrates a side view of the second food member 150. Second foot member 150 has a foot 152 pivotally attached to a shaft 154 that is sized to slide inside the rear member 120 qf the support device 100. A series of apertures 1.56 are provided along the length of the shaft 154. The second foot meniber 150 is telescopically adjustable relative to the rear member 120 by sliding the shaft 154 into the rear member 120 of the support 2o device, the shaft 154 can then be slid inside the rear member 120 until the second foot member 150 is set at the desired height, then a pin (not shown) can be inserted through an apetture 126 provided at the bottom end 124 of the rear member 120 and through one of the series of apertures 156 running along the length of the shaft 154.
Fig. 5 illustrates the support device L00 in a collapsed position for transport. To place the support device 100 in the collapsed position for transport, the top end 122 of the rear member 120 is disconnected from the front member 110. Rear member 120 can then be pivoted around the second end 134 of the brace 130 so that the bottom end 124 of the rear member 120 lies adjacent to the brace 130. The front nieinber 110 is pivoted around the first end 132 of the brace 130 until the front member 110 lies adjacent to the brace 130.
In this manner, the support device 100 can be quickly collapsed for transporting by making a single disconnection (disconnecting the top end 122 of the rear member 120 from the front member 110) and pivoting the front member 110 and rear member 120 so that front member 110 and rear member 120 lie flat and adjacent to the brace 130.
In a further aspect, the front member 110 and rear member 120 can be secured in the collapsed position. A first bracket 210 containing an aperture 215 is positioned on the front inember 110 and a second bracket 220 containing an aperttw 225 is positioned on the rear member 120 so that when the first member 110 and second member 120 are 2o pivoted adjacent the brace 130, placing the support device 100 in the collapsed position.
the aperture 215 in the first bracket 210 and the aperture 225 in the second bracket 220 align with an aperture 230 in the brace 130. A pin (not shown) can then be inserted - Page I I -through the aligned apertures,215, 225, 230 holding the support device 100 in the collapsed position.
Fig. 6 illustrates a plurality of support devices 100 connected together to form a tcmporary dam section 300. F.ach of the support devices 100 are set up in position and a rigid plate 310 is attached to the front surfaces 180 of the front menibers 110 of the support devices 100. Typically, the rigid plate 310 is bolted in at least two places along the length of each front member 110. Fig. 7 illustratcs a front view of the rigid plate 310.
Referring to Figs. 6 and 7 the rigid plate 310 covers substantially the entire front surfaces lo 180 of the front inembers 110 of each support device 100 (In a further aspect, the rigid plate 310 may be made up of a number of smaller plates positioned vertically relative to each other to cover substantially the entire front surface 180 of the front members 110, with cach smaller plate attached to each of the three support dev-ices 100).
The rigid plate 310 has apertures 315 corresponding to the apertures 190 on the front surfaces 180 of the front metnbers 110 of the support devices 100 allowing the rigid plate 310 to be bolted in at least two places to each of the front members 110 so that each of the support devices 100 are held in plaoe by the rigid plate 310. When the rigid plate 310 is bolted to the front surfaces 180 of the front members 110 of the support devices 100, the rigid plate 310 laterally supports each support device 100 in a fixed spaced-apart relatiotuhip relative to the other support devices 100. In this manner, the rigid plate 310 acts as a structural support member in the temporary dike section 300.
]n ordcr to bolt the rigid plate 310 to the front surfaces '180 of the frot-t members 110 of the plurality of suppoit devices 100, the front members 110 must all be aligned in substantially a single plane defuied by the rigid plate 310. If any of the front memben 110 are misaligned relative to the other front members 110, either the rigid plate 110 will not properly bolt to the front member 110 that is misaligned or when the rigid plate 310 is bolted to the front surface 180 of the misaligned front member 110, the support device 100 will not sit properly on the ground surface with both the first foot member 140 and second foot meniber 150 of the support device 100 in contact with the ground surface.
tu Because the dam section 300 will be installed as part of a temporary dam on various different ground surfaces, naany of the ground surfaces will not form a flat surface causing the front surfaces 180 of the support devices 100 to be misaligned.
The first foot members 140 and second foot members 150 of the support devices 100 are used to adjust the support devices 100 so that all of the front surfaces 180 of the front members 110 are aligned so that the rigid plate 310 can he bolted to the front members 110 of the support devices 100.
P.ach first foot member 140 and second foot member 150 on each support device 100 is telescopically adjustable allowing the angle of the front member 110 relative to the ground surface to be altered. By extending the first foot member 140 connected to the bottom end 114 of the front mcmber 110, the angle between the front member 110 relative to the ground surface can he decreased and the height of the apertures 190 on the front members 110 increased. By retracting the fiist foot member 140, the angle between the front member 110 relative to the ground surface can be increased and the height of the apertures 190 on the front surface 180 of -the front member 110 decreased. By extending the second foot member 150 at the bottom end 124 of the rear member 120, the angle of s the front member 110 relative to the ground surfa.ce is increased while the apertures 190 on the front surface 180 of the front member 110 remain at approximately the same heiglit from the ground surface. By retracting the second foot member 150, the angle of the front member 110 relative to the ground surface is decreased while the apertures 180 on the front surface 190 of the front member 110 remain at app.coximately the same io heigttt from the ground surface. Finally, by extending or retracting both the first foot member 140 and second foot member 150, equally, the height of the apertures 190 on the front surface 180 of the front member 110 can be increased or decreased.
respectively, while the angle between the front member 110 and the ground surface remains substantially the same.
In this manner, irregularities in the ground surface can be accounted for using the fust foot members 140 and second foot niembers 150. The first foot member 140 and second foot member 150 of each support device 100 can be used to adjust the front members 110 of the support devices 100 to be positioned in substantially the same plane allowing the ~t) rip d plate 310 to be attached to all of the support devices 110 and aLtina as a structural support holding the support devices 100 in place retative to each other in a lateral spaced apart relationship, while the first foot member 140 and second foot member 150 remain in contact with the ground surfac.e.
Additionall.y, referring to Figs. 1-7, as well as the first fc.x)t niember 140 and second foot member 150 allowing the angle and height of the front surface 180 of the front mernbers 110 of the :support devices 100 to be adjusted, the slot-shaped apertures 190 on the front surface 180 of the front members 110 of the support device.s 100 allow the height of the rigid plate 310 on the front member 110 to be varied up and down relative to the front surface 180 of the front members 110. When the rigid plate 310 is bolted to each of the support devices 100, the slot-shaped apertures 190 allows some vertical adjustment of the rigid plate 310 relative to a front member 110 of a support device 100. in this manner, should the angle of the front fac:e 180 of the front member 110 of a support device 100 be in the proper platie for connection to the rigid plate 310, however the height of the front member 110 differs somewhat rclative to the other support devices 100, the rigid plate 310 can be bolted higher or lower against the front face 180 of the front member 110 using the slot-shaped apertures 190.
Fig 8 illustrates the temporary dike sectioa 300 in a further aspect. A number of reur plates 320 are connected to the rear members 120, with each rear plate 320 securing the rear member 120 of a support device l(X) to the rear member 120 of an adjacent support device 100. Typically, each rear plate 320 is attached in at least two places along a length of the rear members 120 the rear plate 320 is comtected to. The rear plates 320 act irt conjunction with the rigid plate 310 to further support each support devices 100 in a fixeci spaced-apart relationship relative to the other support devices 100.
Referriiig again to Fig. 6, a single dam section 300 is shown with three (3) support devices 100 used in the dam section 300. By connecting a number of datn sections 300 together a temporary dam of any practical length can be achieved in order to contain a body of water. Fig_ 9 illustrates a first dam section 300A connected to a second dam section 300B. The first dam seciion 330A has a fint rigid plate 310A with a first end 302A and a second end 304A. The second dam section 330B has a second rigid plate lo 310B with a first end 302B and a second end 304B. The first dam section 300A can be connected to the second dam section 300B by connecting both the second end 304A of the first rigid plate 310A and the first end 302B of the second rigid plate 310B to a sbared support device 100A. in this manner, the second end 304A of the first rigid plate 310 overlaps the first end 302B of the second rigid plate 310$, or vice versa, with the shared support device 100A attached to both the first rigid plate 310A and the second rigid plate 310B.
Referring again to Fig. 6, by connecting a number of dam sections 300 together in the manner outlined, overlapping the rigid plates 310 so that one of the support devices 100 on the end of the rigid plates 310 is connected to the ends of two rigid plates 310, a temporary dam of any practical length made up of dam sections 300 can be assembly with each dam section 300 coimected to an adjacent dam section 300 with a shared - Paue 16 -support device 100 forming a continuous wall of rigid plates 310 facing a body of water to be contained.
Once the desired length of temporary dam, made up of dam sections 300, is constructed, a liquid impervious membrane is used to cover the rigid plates 310 allowing the temporary dam to contain a body of water. Fig. 10 illustrates a side view of a temporary dam 480 with a flexible liquid impervious membrane 400 used to contain a body of water 420. The membrane 400 is placed over top of the rigid plates 310 cKeating a barrier to the water 420. The membrane 400 is held in place, against the pre.ssure of the contained lo water 320, by the rigid plates 310 with the rigid plates 310 forming a solid, unbroken surface supporting the membrane 400 against the water pressure of the body of water 420. Most of the force of the water pressure acting on the membrane is transfened through the tnembrane 400 to the rigid plate 310 supporting the membrane 400, which then transfers the force through the support devices 100 and down to the ground surface 450. The membrane 400 extends below the bottom of the rigid plate 310 out onto the ground surface 450 in front of the temporary dam 480. The water pressure on the membrane 400 extending onto the ground surface 450 in front of the temporary dam 480 seals the tentporary dam 480 and prevents the body of water 420 from passing under the temporary dam 480.
By combining any practical number of dam sections 300 together a straight temporary darn of any practical length can be constructed (assuming a person has enough rigid - Page !7 -plates 310 and support devices 100) to contain a body of water. However in many situations a perfectly straight dam is not always desirable or sufficient.
Often it is desirable or required to have the temporary dam tum and curve, in order to get around obstacles, go around corners, join existiuig embankments, etc. Figs. Il and 12 illusstrate s front and bottom views of a corner piece 400 that allows a temporary dam formed of dam sections 300 to be angled or turned. The comer piece 4(i) has a main body 405 in the shape of a truncated isosceles triangle. The main body 405 has two side edges having substantially the same length with flanges 420 connected along the side edges 410. As can be seen in Fig. 12, the flanges 420 are angled upwards from the main body to 405. The tlanges 420 have apertures 430 placed along the length of the flanges 420 that correspond to the apertures 190 in the front face 180 of the front member 110 of the support devices 100 shown in Fig. 2. A short edge 440 and a long edge 450 are provided along the top and bottoni of the main body 404 of the corner piece 400.
15 Fig. 13 illustrates a temporary dam 500 formed from a first dam section 300C, sewnd dam section 300D and third datn section 300E connected by eorner pieces 400A
and 400B to angle the dam 500, The corrter piece 400A is positioned between the first dam section 300C and second dam section 300D by lining up the apertures 430 on each flange 420 with the apertures 315 on the rigid plate 310 and the apertures 190 on the front 20 surface 180 of the front members 110 of the support devices 100 on the ends of the first and second temporary dike section 300A, 300B. respectively.
- Pnee 1 R -By placing the short edge 440 of the corner piece 400A above the long edge 450 so that the short edge 440 is closer to a ground surface, the temporary dam 500 can be angled towards the body of water it is containing, as shown with angle between the first dam section 300C and second dam section 300D connected by corner piece 400A. By turning the conier piece 4003 upside down and placing the short edge 440 below the long edge 450, the temporary dam 500 can be angled away from the body of viwater the dam 500 will contain, as shown with the angle between the second dam section 300D and the third dam section 300E connected by cor.ner piece 400B. To form a tighter angle in either direction, two corner pieces 400 can be placed adjacent to each other, with a support device 100 positioned between them.
In this manner, corner pieces 400 can be tised to angle the temporary dam 500 either inwards towards the body of water or outwards away from the body of water to be contained depending on the requirements of a specific site where the temporary dain 500 will be constructed. Each corner piece 400 can be installed either upwards or duwnwards, allowing a single type of corner piece 400 to be used to either angle the temporary dike 500 inwards or outwards depending on the requirements of a specific application.
The foregoing is considered as illustrative only of the principles of the invention.
Furt,her, since numerous changes and ntodifications will readily occur to thase skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and de,.tcrihcd, and accordingly, all such suitable changes or modifications in structure or operation which may be resorted to are intended to fall within the scope of the claimed invention.
Tliis invention is in the field of teniporary water contaittment dams and more particular a portable system that can be assembled into a temporary water contair,tnent dam.

Temporary dams or dikes are often needed to hold back water, whether for emcrgency to flood control, water diversion, repairs to structures normally stumund or covered by water such as bridges or batilcs, construction projects, etc. Conventionally, sandbags and earthen benns trre used in theses situations to form dikes to contain the water, however, these methods are time consuming and very labor intensive.
If sandbags are used to build a containment wall or dike, it takes a nuniber of people to fill the individual sandbags and then place them in position in the wall being formed.
Because the sand bags are stacked on top of each other to form the wall, if the wall needs to be relatively high, quite a wide base of sandbags is often needed.
Additionally, not only does it take a lot of labor to fill and place the sandbags, it also takes a lot of labor to deconstruct sandbag walls after it they no longer needed. Especially in emergency situations, it is often hard to prioritize the necessary labor to deconstruct the sandbag wall after a crisis is over. In the case of earthen berms, large machinery is often needed to Pat,re2-eonstnict them and this can be troublesome or even dangerous in the circumstances.
Additiottally, both of these tnethods can involve a relatively high environmental impa,ct.
In the case of sandbags, sand lcft behind from the sandbags can have an environmental impact. In tlie case of eartheii berms, often the dirt for the berm is taken from the site causing an impact on the surrounding environment and often the earthen betm cannot be leveled completed when it is no longer nceded, leaving traces of the berm behind.
Because of the time and labor requirements needed to create a temporary containment wall of sandbags or an earthen berm, a uumber of portable dam devices and systems have been developed for creating teinporary water containment dikes. These devices have been developed to be relativel.y tt-ansportable and quick to set up with less labor required than needed for sandbags or earthen berms. '1'hey typically consist of a framework that can be assembled at a site to create the temporary dam.
1.5 Because of the substantial hydrostatic pressure that can he exerted on these strttctares as a result of them having to hold back a body of water, these systems also have to be sufficiently strong to withstand the force exerted on them by the water.
Additionally.
because they will have to be quickly set up on whatever grottnd surface is present at the site of the body of water, they have to be relative conipact to be transportable and relative z0 quick to set up. These reqttirements have resulted in previous systems heing relatively complicated, consisting of numerous braces, connection points and suppon members.
Especially in the case of lateral support, the previous systems often require quite complex ways of linking the temporary structure to provide lateral support, which oftem involves numerous braces and lateral support members.
Accordingly, there is a need for a portable and temporary dam system that is sufficiently strong to contain a body of water, yet relatively simple, transportable and easy to set up.
S[JM11~tiARY OF TIiE INVENTION
j0 It is an object of the present invention to provide a system and method that overcomes problems in the prior art.
In a first aspect, a temporary dam system for containing water is provided.
The system comprises a plurality of dam sections. Each dam section hasg: at ieast three support devices, each support device having: a front member having a top end, a bottom end and a front surface; a rear member having a top end and a bottom end, the rear member connected at the top end of the rear member to the front member; an adjustable first foot incmber provided on the bottom end of the front member, the first foot member operative to adjust the height of the bottom end of the front member; an adjustable second foot member provided on the bottoni end of the rear member. the second foot member operative to adjust the height of the bottom end of the rear member; and a brace having a first end and a second end, the brace connected at the first end of the brace to the front member and connected at the second end of the brace to the rear member, and at least one rigid sheet attached to each front surface of each front members of each of the at least three support devices, the at least one rigid sheet tnaintaitting the at least three support devices in a fixed, spaced apart reiationship and maintaining the front surfaces of the front members of each of the at least three support devices substantially in a single plan defined by the rigid sheet. The system also has a flexible liquid-impervious membrane substantially placed over the rigid sheets of the dam sections and extending onto a ground surface in front of the dam sections.
to In an aspect, a temporary dam system for containing a body of water is provided. The temporary dam system is constructed with a number of dam sections. Each dam section has three or tuore support devices attached to one or more rigid plates. The support devices consist of a front meniber, a rear member, and a brace in an A-frame structnre.
The rigid plate is attached to a front stuface of the front niember of each of the support devices and acts as a stnictural component of the dam section maintaining the support devices in a fixed lateral position relative to the other support devices.
The dam system is constructed by connecting a number of dam sections together to form a continuous wall of rigid plates facing a body of water to be contained. A
t7exible 2o liquid-impervious membrane is then placed over the rigid plates extending down onto a ground surtace in front of the dam. The membrane stops the water, and the rigid plates supported by the support devices maintain the membrane in place.
PageS-The dam can be broken down for transport by disconnecting the dam sections and then for each dam section, removizig the rigid plate from the support devices. In an a:spect, a top end of the rear member of the suppoi-t devices is releasably connectable to the front meniber and the brace is pivotally connected to both the front member and the rear ritember. This allows the support devices to be further collapsed for transport by disconnecting the top end of the rear member from the front member and pivoting the front member and rear member around the brace so that the front member, brace and rear member all lie adjacent to each other.
A straight datn is not always ideal in every situation. Often, it is desirable to be able to angle the dam so that it can be turned around obstacles, etc. In an aspect, a eorner piece is provided that allows the temporary dam to be tu-ned and angled. The corner piece has a main body in the shape of a truncated isosceles triangle. Flanges angled upwards frnm the main body are attached to the two equal side edges of the main body. By connecting the comer piece between two dam sections, with the flanges connected to support devices on the ends of dam sections, a dam can be angled either towards a body of water being contained or away froni a body of water being contaiuied, depending on whether or not the comer piece is positioned upwards or downwards between the dam sections.
For an evcn greater angle, two comer pieces can be connected adjacent to each other.

The front member 110 has a top end 112 and a bottom end 114. The rear member has a top end 122 and a bottom end 124 and the rear member 120 is releasably connectable at the top end 122 to the front member 110. In an aspect, the rear member 120 is releasably connectable to the front member 110 so that the rear member 120 is positioned substantially perpendicular to the front mentber 110, when the rear member to 120 is connected to the front member 110.
The brace 130 and has a first end 132 and a second end 134. The first end 132 of the brace 130 is pivotally connected front member 110 and the second end 134 of the brace 130 is pivotally connected to the rear member 120.
A first foot member 140 and seeond foot member 150 are used to support the front member 110 and rear member 120, respectively, on a ground surface. The first foot member 140 is telescopically and pivotally connected to the bottom end 114 of the front member 110 and the second foot member 150 is telescopically and pivotally connected to the bottom end 124 of the rear member 120.
F140e9-Fig 2 illustrates a front view of the support device 100. A front surface 180 of the front member 110 has a nuniber of slot-shaped apertures 190 provided along a length of the front member 110.
Fig. 3 illustrates a side view of the first foot member 140. First foot member 140 has a foot 142 pivotally attached to a shaft 144 that is sized to slide inside the front member 110 of the support device 100. A series of apertures 146 are provided along the length of the shaft 144. The first foot member 140 is telescopically adjustable relative to the front member 110 by siiding the shaft 144 into the front member 110 of the support device, the to shaft 144 can then be slid inside the front member 110 until the first foot member 140 is set at the desired height, Ihen a pin (not shown) can be inserted through an aperture 116 provided at the bottom end 114 of the front member 110 and through one of the series of apertures 146 running along the length of the shaft 144.
Fig. 4 illustrates a side view of the second food member 150. Second foot member 150 has a foot 152 pivotally attached to a shaft 154 that is sized to slide inside the rear member 120 qf the support device 100. A series of apertures 1.56 are provided along the length of the shaft 154. The second foot meniber 150 is telescopically adjustable relative to the rear member 120 by sliding the shaft 154 into the rear member 120 of the support 2o device, the shaft 154 can then be slid inside the rear member 120 until the second foot member 150 is set at the desired height, then a pin (not shown) can be inserted through an apetture 126 provided at the bottom end 124 of the rear member 120 and through one of the series of apertures 156 running along the length of the shaft 154.
Fig. 5 illustrates the support device L00 in a collapsed position for transport. To place the support device 100 in the collapsed position for transport, the top end 122 of the rear member 120 is disconnected from the front member 110. Rear member 120 can then be pivoted around the second end 134 of the brace 130 so that the bottom end 124 of the rear member 120 lies adjacent to the brace 130. The front nieinber 110 is pivoted around the first end 132 of the brace 130 until the front member 110 lies adjacent to the brace 130.
In this manner, the support device 100 can be quickly collapsed for transporting by making a single disconnection (disconnecting the top end 122 of the rear member 120 from the front member 110) and pivoting the front member 110 and rear member 120 so that front member 110 and rear member 120 lie flat and adjacent to the brace 130.
In a further aspect, the front member 110 and rear member 120 can be secured in the collapsed position. A first bracket 210 containing an aperture 215 is positioned on the front inember 110 and a second bracket 220 containing an aperttw 225 is positioned on the rear member 120 so that when the first member 110 and second member 120 are 2o pivoted adjacent the brace 130, placing the support device 100 in the collapsed position.
the aperture 215 in the first bracket 210 and the aperture 225 in the second bracket 220 align with an aperture 230 in the brace 130. A pin (not shown) can then be inserted - Page I I -through the aligned apertures,215, 225, 230 holding the support device 100 in the collapsed position.
Fig. 6 illustrates a plurality of support devices 100 connected together to form a tcmporary dam section 300. F.ach of the support devices 100 are set up in position and a rigid plate 310 is attached to the front surfaces 180 of the front menibers 110 of the support devices 100. Typically, the rigid plate 310 is bolted in at least two places along the length of each front member 110. Fig. 7 illustratcs a front view of the rigid plate 310.
Referring to Figs. 6 and 7 the rigid plate 310 covers substantially the entire front surfaces lo 180 of the front inembers 110 of each support device 100 (In a further aspect, the rigid plate 310 may be made up of a number of smaller plates positioned vertically relative to each other to cover substantially the entire front surface 180 of the front members 110, with cach smaller plate attached to each of the three support dev-ices 100).
The rigid plate 310 has apertures 315 corresponding to the apertures 190 on the front surfaces 180 of the front metnbers 110 of the support devices 100 allowing the rigid plate 310 to be bolted in at least two places to each of the front members 110 so that each of the support devices 100 are held in plaoe by the rigid plate 310. When the rigid plate 310 is bolted to the front surfaces 180 of the front members 110 of the support devices 100, the rigid plate 310 laterally supports each support device 100 in a fixed spaced-apart relatiotuhip relative to the other support devices 100. In this manner, the rigid plate 310 acts as a structural support member in the temporary dike section 300.
]n ordcr to bolt the rigid plate 310 to the front surfaces '180 of the frot-t members 110 of the plurality of suppoit devices 100, the front members 110 must all be aligned in substantially a single plane defuied by the rigid plate 310. If any of the front memben 110 are misaligned relative to the other front members 110, either the rigid plate 110 will not properly bolt to the front member 110 that is misaligned or when the rigid plate 310 is bolted to the front surface 180 of the misaligned front member 110, the support device 100 will not sit properly on the ground surface with both the first foot member 140 and second foot meniber 150 of the support device 100 in contact with the ground surface.
tu Because the dam section 300 will be installed as part of a temporary dam on various different ground surfaces, naany of the ground surfaces will not form a flat surface causing the front surfaces 180 of the support devices 100 to be misaligned.
The first foot members 140 and second foot members 150 of the support devices 100 are used to adjust the support devices 100 so that all of the front surfaces 180 of the front members 110 are aligned so that the rigid plate 310 can he bolted to the front members 110 of the support devices 100.
P.ach first foot member 140 and second foot member 150 on each support device 100 is telescopically adjustable allowing the angle of the front member 110 relative to the ground surface to be altered. By extending the first foot member 140 connected to the bottom end 114 of the front mcmber 110, the angle between the front member 110 relative to the ground surface can he decreased and the height of the apertures 190 on the front members 110 increased. By retracting the fiist foot member 140, the angle between the front member 110 relative to the ground surface can be increased and the height of the apertures 190 on the front surface 180 of -the front member 110 decreased. By extending the second foot member 150 at the bottom end 124 of the rear member 120, the angle of s the front member 110 relative to the ground surfa.ce is increased while the apertures 190 on the front surface 180 of the front member 110 remain at approximately the same heiglit from the ground surface. By retracting the second foot member 150, the angle of the front member 110 relative to the ground surface is decreased while the apertures 180 on the front surface 190 of the front member 110 remain at app.coximately the same io heigttt from the ground surface. Finally, by extending or retracting both the first foot member 140 and second foot member 150, equally, the height of the apertures 190 on the front surface 180 of the front member 110 can be increased or decreased.
respectively, while the angle between the front member 110 and the ground surface remains substantially the same.
In this manner, irregularities in the ground surface can be accounted for using the fust foot members 140 and second foot niembers 150. The first foot member 140 and second foot member 150 of each support device 100 can be used to adjust the front members 110 of the support devices 100 to be positioned in substantially the same plane allowing the ~t) rip d plate 310 to be attached to all of the support devices 110 and aLtina as a structural support holding the support devices 100 in place retative to each other in a lateral spaced apart relationship, while the first foot member 140 and second foot member 150 remain in contact with the ground surfac.e.
Additionall.y, referring to Figs. 1-7, as well as the first fc.x)t niember 140 and second foot member 150 allowing the angle and height of the front surface 180 of the front mernbers 110 of the :support devices 100 to be adjusted, the slot-shaped apertures 190 on the front surface 180 of the front members 110 of the support device.s 100 allow the height of the rigid plate 310 on the front member 110 to be varied up and down relative to the front surface 180 of the front members 110. When the rigid plate 310 is bolted to each of the support devices 100, the slot-shaped apertures 190 allows some vertical adjustment of the rigid plate 310 relative to a front member 110 of a support device 100. in this manner, should the angle of the front fac:e 180 of the front member 110 of a support device 100 be in the proper platie for connection to the rigid plate 310, however the height of the front member 110 differs somewhat rclative to the other support devices 100, the rigid plate 310 can be bolted higher or lower against the front face 180 of the front member 110 using the slot-shaped apertures 190.
Fig 8 illustrates the temporary dike sectioa 300 in a further aspect. A number of reur plates 320 are connected to the rear members 120, with each rear plate 320 securing the rear member 120 of a support device l(X) to the rear member 120 of an adjacent support device 100. Typically, each rear plate 320 is attached in at least two places along a length of the rear members 120 the rear plate 320 is comtected to. The rear plates 320 act irt conjunction with the rigid plate 310 to further support each support devices 100 in a fixeci spaced-apart relationship relative to the other support devices 100.
Referriiig again to Fig. 6, a single dam section 300 is shown with three (3) support devices 100 used in the dam section 300. By connecting a number of datn sections 300 together a temporary dam of any practical length can be achieved in order to contain a body of water. Fig_ 9 illustrates a first dam section 300A connected to a second dam section 300B. The first dam seciion 330A has a fint rigid plate 310A with a first end 302A and a second end 304A. The second dam section 330B has a second rigid plate lo 310B with a first end 302B and a second end 304B. The first dam section 300A can be connected to the second dam section 300B by connecting both the second end 304A of the first rigid plate 310A and the first end 302B of the second rigid plate 310B to a sbared support device 100A. in this manner, the second end 304A of the first rigid plate 310 overlaps the first end 302B of the second rigid plate 310$, or vice versa, with the shared support device 100A attached to both the first rigid plate 310A and the second rigid plate 310B.
Referring again to Fig. 6, by connecting a number of dam sections 300 together in the manner outlined, overlapping the rigid plates 310 so that one of the support devices 100 on the end of the rigid plates 310 is connected to the ends of two rigid plates 310, a temporary dam of any practical length made up of dam sections 300 can be assembly with each dam section 300 coimected to an adjacent dam section 300 with a shared - Paue 16 -support device 100 forming a continuous wall of rigid plates 310 facing a body of water to be contained.
Once the desired length of temporary dam, made up of dam sections 300, is constructed, a liquid impervious membrane is used to cover the rigid plates 310 allowing the temporary dam to contain a body of water. Fig. 10 illustrates a side view of a temporary dam 480 with a flexible liquid impervious membrane 400 used to contain a body of water 420. The membrane 400 is placed over top of the rigid plates 310 cKeating a barrier to the water 420. The membrane 400 is held in place, against the pre.ssure of the contained lo water 320, by the rigid plates 310 with the rigid plates 310 forming a solid, unbroken surface supporting the membrane 400 against the water pressure of the body of water 420. Most of the force of the water pressure acting on the membrane is transfened through the tnembrane 400 to the rigid plate 310 supporting the membrane 400, which then transfers the force through the support devices 100 and down to the ground surface 450. The membrane 400 extends below the bottom of the rigid plate 310 out onto the ground surface 450 in front of the temporary dam 480. The water pressure on the membrane 400 extending onto the ground surface 450 in front of the temporary dam 480 seals the tentporary dam 480 and prevents the body of water 420 from passing under the temporary dam 480.
By combining any practical number of dam sections 300 together a straight temporary darn of any practical length can be constructed (assuming a person has enough rigid - Page !7 -plates 310 and support devices 100) to contain a body of water. However in many situations a perfectly straight dam is not always desirable or sufficient.
Often it is desirable or required to have the temporary dam tum and curve, in order to get around obstacles, go around corners, join existiuig embankments, etc. Figs. Il and 12 illusstrate s front and bottom views of a corner piece 400 that allows a temporary dam formed of dam sections 300 to be angled or turned. The comer piece 4(i) has a main body 405 in the shape of a truncated isosceles triangle. The main body 405 has two side edges having substantially the same length with flanges 420 connected along the side edges 410. As can be seen in Fig. 12, the flanges 420 are angled upwards from the main body to 405. The tlanges 420 have apertures 430 placed along the length of the flanges 420 that correspond to the apertures 190 in the front face 180 of the front member 110 of the support devices 100 shown in Fig. 2. A short edge 440 and a long edge 450 are provided along the top and bottoni of the main body 404 of the corner piece 400.
15 Fig. 13 illustrates a temporary dam 500 formed from a first dam section 300C, sewnd dam section 300D and third datn section 300E connected by eorner pieces 400A
and 400B to angle the dam 500, The corrter piece 400A is positioned between the first dam section 300C and second dam section 300D by lining up the apertures 430 on each flange 420 with the apertures 315 on the rigid plate 310 and the apertures 190 on the front 20 surface 180 of the front members 110 of the support devices 100 on the ends of the first and second temporary dike section 300A, 300B. respectively.
- Pnee 1 R -By placing the short edge 440 of the corner piece 400A above the long edge 450 so that the short edge 440 is closer to a ground surface, the temporary dam 500 can be angled towards the body of water it is containing, as shown with angle between the first dam section 300C and second dam section 300D connected by corner piece 400A. By turning the conier piece 4003 upside down and placing the short edge 440 below the long edge 450, the temporary dam 500 can be angled away from the body of viwater the dam 500 will contain, as shown with the angle between the second dam section 300D and the third dam section 300E connected by cor.ner piece 400B. To form a tighter angle in either direction, two corner pieces 400 can be placed adjacent to each other, with a support device 100 positioned between them.
In this manner, corner pieces 400 can be tised to angle the temporary dam 500 either inwards towards the body of water or outwards away from the body of water to be contained depending on the requirements of a specific site where the temporary dain 500 will be constructed. Each corner piece 400 can be installed either upwards or duwnwards, allowing a single type of corner piece 400 to be used to either angle the temporary dike 500 inwards or outwards depending on the requirements of a specific application.
The foregoing is considered as illustrative only of the principles of the invention.
Furt,her, since numerous changes and ntodifications will readily occur to thase skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and de,.tcrihcd, and accordingly, all such suitable changes or modifications in structure or operation which may be resorted to are intended to fall within the scope of the claimed invention.
