Embodiments of the present invention are related to an apparatus and method for diverting a surge of water caused by a storm, or any occurrence that causes water to precariously rise. More specifically, embodiments of the present invention provide an apparatus (i.e., an aqueduct assembly) and method for protecting people, property, and animal life, located behind levees by channeling water into the apparatus, and channeling the water from the apparatus onto a desired location, such as marsh land.
A hurricane, such as Katrina, in the Gulf of Mexico, can cause water levels to rise well above normal, especially in coastal areas. When this occurs near the mouth of a river, such as the Mississippi river, water levels in the river can rise to dangerous levels.
Water from a body of water (e.g., the Gulf of Mexico) into which the river empties, is forced up the river, colliding with water flowing down the river and towards the body of water. This causes water pressure against levees to increase, to the point of either flowing over the levees and/or bursting the levees to endanger people, property, and animal life, located behind levees. What is needed is a storm-surge apparatus which will alleviate, or eliminate, the water pressure against the levees.
Embodiments of the present invention provide an aqueduct assembly having a front gate assembly and a rear gate assembly. A front gate of the front gate assembly will open in accordance with the level of water coming in contact with it. As the front gate opens, water enters the aqueduct assembly. When water begins to rise in the aqueduct assembly, a rear gate of the rear gate assembly begins to open. As the rear gate opens, water in the aqueduct assembly begins to flow out of the aqueduct assembly onto any desired land, such as marsh land.
Embodiments of the present invention also provide a method for diverting water from a body of water onto land. The method includes elevating a front gate assembly for allowing water to flow into an aqueduct assembly, and subsequently elevating a rear gate assembly for permitting water to flow out of the aqueduct assembly. In an embodiment of the invention, the method further includes disengaging a front flotation device from a front gate to prevent water from flowing into the aqueduct assembly, and opening a valve member to permit water to flow into the aqueduct assembly and through a rear gate assembly.
These provisions, together with the various ancillary provisions and features which will become apparent to those skilled in the art as the following description proceeds, are attained by the methods and assemblies of the present invention.
In the description herein, numerous specific details are provided, such as examples of components and/or methods, to provide a thorough understanding of the embodiments of the present invention. One skilled in the relevant art will recognize, however, that an embodiment of the invention may be practiced without one or more of the specific details, or with other apparatus, systems, assemblies, methods, components, materials, parts, and/or the like. In other instances, well-known structures, materials, or operations are not specifically shown or described in detail to avoid obscuring aspects of the embodiments of the present invention.
Referring in detail now to the drawings, wherein similar parts of the invention are identified by like reference numerals, there is seen an apparatus, i.e. a storm-surge aqueduct assembly, generally illustrated as 10. The aqueduct assembly 10 includes a front gate assembly 14 and a rear gate assembly 18. In operation of various embodiments of the invention, the front gate assembly 14 is typically located near a river or any other body of water that is capable of rising to a precarious level. For purpose of describing embodiments of the present invention, the front gate assembly 14 will be described as being near a river, such as the Mississippi river. The rear gate assembly 18 is typically located near a section of land that is suitable for receiving water that has been removed from the river. For various embodiments of the present invention, the land for receiving river water will be marsh land, such as land in proximity to the Mississippi river.
The aqueduct assembly 10 typically contains a bottom 22 supporting a pair of side frames 26 and 30. A flange member 34 is coupled to the side frames 26 and 30 which respectively include drainage pipes 38 and 42 that respectively terminate at internal openings 46 and 50 in the side frames 26 and 30. The side frames 26 and 30 respectively support gate valves 54 and 58 for controlling the flow of water through the respective drainage pipes 38 and 42.
The aqueduct assembly 10 may straddle and/or intercept levees, such as spaced levees 70 and 74 as seen in
In another embodiment of the invention, which depends on the slope of the land behind the levee that is contiguous to the river, the aqueduct assembly 10 may be employed when only one levee exists, i.e. levee 70. For this embodiment of the invention, water collects behind levee 70 and at points that register and are longitudinally aligned with drainage pipes 38 and 42. Water would be passed into and through the open rear gate assembly 18 in accordance with the procedure (i.e., opening gate valves 54 and/or 58) that is employed for removing water between two levees, i.e., levees 70 and 74. In an embodiment where a single levee (e.g., levee 70) is employed and where assembly 10 bisects, separates or intercepts the single levee, any water seeping between the assembly 10 and the intercepted/separated section of the single levee may be removed in accordance with the procedure for removing water.
In an embodiment of the invention, levee-engager members 78 may be supported by the flange member 34 for coupling levees 70 and 74 to the aqueduct assembly 10. When the levee-engager members 78 are engaged to levees 70 and 74, the aqueduct assembly 10 is anchored into a steadfast position while simultaneously allowing the drainage pipes 30 and 42 to be in contact with any water disposed between levees 70 and 74. The levee-engager members 78 may be any suitable members which are capable of functioning for their purposes. In an embodiment of the invention, levee-engager members 78 are generally configured to the shape of a levee, such as triangular (hollow or solid) as shown in
In an embodiment of the invention, a protection guard assembly 62 is coupled to ends of the side frames 26 and 30, as illustrated in
The front gate assembly 14 controls the passage of water into the aqueduct assembly 10 and comprises a riverside gate flotation device 82, brackets 86-86 respectively connected to opposed ends of the flotation device 82, and ends of the respective brackets 86-86 connected to rod 90 which is rotatably secured to frames 26 and 30. In an embodiment of the invention, a gate rod 102 is provided. A gate rod 102 is also rotatably secured to frames 26 and 30. Gate 110 is coupled to gate rod 102 such that as gate 110 moves (e.g., up and down) gate rod 102 rotates on frames 26 and 28. A hook-engaging rod 114 is connected to the gate 110. In an embodiment of the invention gate 110 may be secured pivotally to rod 90 (rod 102 would not be needed). In yet another embodiment of the invention, rod 90 (or rod 102) is affixed, say to frames 26 and 30, and gate 110 and flotation device 82 are pivotally coupled to rod 90 (or rod 102). More specifically, brackets, 86-86 and gate 110 pivot about rod 90 (or rod 102) while rod 90 (or rod 102) remains stationary, as best shown in
The front gate assembly 14 also includes a rod 94 coupled to the brackets 86, and a pair of hooks 98-98 which are movably mounted on rod 94. As best shown in
The aqueduct assembly 10 is situated at a desired elevation above the river. When hooks 98-98 are engaged to the hook-engaging rod 114, as the gate flotation device 82 rises when coming in contact with river water, the gate 110 (coupled to the flotation device 82) also rises along with the gate flotation device 82. As the river water subsides, the gate flotation device 82 commences to move downwardly from not being in contact with any river water. As the gate flotation device 82 moves downwardly, gate 110 also moves downwardly until gate 110 closes off the front gate assembly 14.
When hooks 98-98 are disengaged from the hook-engaging rod 114, the gate flotation device 82 may rise and fall independently of gate 110, and gate 110, depending on its weight and the rate of inflow of river water through the front gate assembly 14, may (or would) sink into contact with the bottom 22, as shown in
In another embodiment of the invention, the front gate assembly 14 may be closed solely with gate 110, as illustrated in
If the hydraulic pump/motor 130 disengages hooks 98-98 from the hook-engaging rod 114 before the river water comes into sufficient contact with the front gate assembly 14, as the river water contacts the front gate assembly 14 and commences to rise, the flotation device 82 rises (independent of the gate 110) along with the rising river water, until eventually reaching the position illustrated in
If the hydraulic pump/motor 130 disengages the hooks 98-98 from the hook-engaging rod 114 after the river water has been in contact with the front gate assembly 14, and after the front gate assembly 14 has been in the position illustrated in
The front gate assembly 14 of the aqueduct assembly 10 may also include a water pump 140 and a water hose 144 coupled to the water pump 140 and to the flotation device 82. A vent line 150 is conveniently coupled to the flotation device 82 for venting trapped air from within the flotation device 82 into the atmosphere.
In one embodiment of the invention, the water pump 140 may be used to add water into the flotation device 82 to prevent the flotation device 82 from rising when coming in contact with river water. The source of water may be from any suitable source, such as the river itself. When the flotation device 82 is filled with water, the flotation device 82 will not rise when coming in contact with river water due to the weight (pressure) of the river water and lack of buoyancy. Because the flotation device 82 does not rise, the gate 110 will not rise and will remain closed due to the flotation device 82 weighing more than the gate 110 and/or from the force of river water flowing against the gate 110. Alternatively, air may be used instead of water for raising or lowering the flotation device 80.
The water pump 140 may remove river water from the flotation device 82 as desired. Thus, and in another embodiment of the invention, the flotation device 82 may be caused to rise independently of the gate 110, without the gate 110 moving simultaneously with the flotation device 82, by the hydraulic pump/motor 130 disengaging the hooks 98 from the hook-engaging rod 114 (a latch bar) and removing (with the water pump 140) river water from the flotation device 82. This causes a decrease in weight, and an increase in buoyancy, of the flotation device 82, which subsequently causes the flotation device 82 to elevate while the gate 110 remains in place (see
The procedure may be reversed in another embodiment of the invention; that is, the flotation device 82 may be lowered [from its position illustrated in
The rear gate assembly 18 is structurally similar to the front gate assembly 14 in that it includes a rear flotation device 150 and a rear gate 156 which are coupled together at their tops by a coupling assembly, generally illustrated as 160, such that when the flotation device 150 moves from rising river water within the aqueduct assembly 10, the rear gate 156 will also move simultaneously with the flotation device 150. As previously indicated, water may be released (i.e., through the front gate assembly 14) into the aqueduct assembly 10 from the river, or water (i.e. water between levees) may be released (through drainage pipes 38 and 42) into the aqueduct assembly 10 from land between two levees. When there is no more water in the aqueduct assembly 10, the rear flotation device 150 will drop which causes the rear gate 156 to drop and close the rear gate assembly 18.
The coupling assembly 160 may be any suitable coupling assembly that is capable of opening the rear gate 156 as the rear flotation device 150 pivotally elevates as the level of water in the aqueduct assembly 10 rises. In an embodiment of the invention, the coupling assembly 160 comprises a pair of flotation gears 170-170 which are respectively trained to a pair of gate gears 174-174. Gears 170-170 couple to rod 171. Brackets 177-177 couple flotation device 150 to rod 171. Gears 174-174 and rear gate 156 are coupled to rod 173.
As water passes through the drainage pipes 38 and 42, or through the front gate assembly 14, water in the aqueduct begins to rise causing the rear flotation device 150 to rise. As the rear flotation device 150 rises, gears 170 and 174 rotate accordingly, and the rear gate 156 starts rising which causes water to start exiting the aqueduct and passing on to the marsh land. As the level of water in the aqueduct begins to subside, the rear flotation device 150 begins to lower which causes the rear gate 156 to commence closing from the downwardly movement of the flotation gear device 150 being translated to the rear gate 156 through the appropriate rotation of the gears 170 and 174.

Practices of embodiments of the present invention provide a storm-surge diversion assembly that will alleviate or eliminate water pressure against levees. In an embodiment of the invention, the storm-surge aqueduct assembly is strategically placed in proximity to the mouth of a river. For some embodiments of the invention, no personnel would be needed to operate the assembly during a hurricane. When the water level in the river rises, the front flotation device will lift the front gate assembly to allow water to flow into the aqueduct. As water flows into the aqueduct, the rear or back gate assembly rises to allow water to flow from the aqueduct into marsh lands.
The storm-surge aqueduct assembly may be employed in any suitable manner. By way of example only and for an embodiment of the invention, the storm-surge aqueduct assembly may include two pairs of water-directing spaced petitions which respectively protrude from sides of the storm-surge assembly. Each pair of petitions may respectively align with each pair of levees in a two levee system where the levees are spaced from each other at essentially the same distance as the water-containing petitions are spaced from each other. In the event water breaches the levee nearest the river, the water may be contained between the breached front levee and the rear of back levee.
