The present invention relates to inflatable bladder actuated water control gates for control of open channels such as rivers and canals and for control of dam spillways without the need for intermediate piers. The air bladder and hinge flap wedge clamping system includes hinged engagement of the upstream edge of the clamps to the foundation so as to prevent the application of bending and shear loads to the anchor bolts. The resulting configuration facilitates the use of high strength alloy steel anchor bolts in a corrosion protected environment and also prevents tensile loading of the concrete foundation and associated cracking of the concrete foundation.

A cabled, non-inflatable type flexible wall dam for restraining or controlling the flow of water is disclosed. The cables and flexible wall of present invention are arranged in a manner that enables present flexible wall dams to open (lower) and close (raise) for controlling the flow of water. Present invention includes a reinforcement method that has a net like reinforcement layer and reinforcement cables, and therefore the dams of present invention can be built to be stronger, larger, and higher than the most commonly used inflatable flexible wall dams.

An inflatable dam sized to secure to a foundation structure. The inflatable dam includes a double layered flexible membrane extending with an inner membrane and an outer membrane, the double layered flexible membrane including a port configured to facilitate inflation and deflation of the inner membrane such that, upon inflation of the inner membrane, the outer membrane is configured to expand with inflation of the inner membrane, the outer membrane including a reinforcement element embedded therein.

The invention relates to improved water control gates and related inflatable actuators, and associated sealing, manufacture and operation apparatus and methods. Advancements in technologies related to air fitting design, inflated bladder stress relief, inflatable bladder strength enhancement, water gate related slide friction mitigation, abutment and other impounded water seals, gate panel fabrication, traffic accommodating water impoundment structures, and water gate panel system operation efficiency, as well as nappe aeration, hinges, and bladder manufacture technology are disclosed herein.

A system and method for constructing any desired length of height linear cellular chain for use as a protective wall system, including a chain of fabric bulk bags, each having an open upper end, and interconnected along their sidewalls to define the cellular chain; and a fabric channel formed on the upper ends of each of the adjoining bags sidewalls for engaging a bag support and filling system, which includes a first metal frame member having a pair of arm members for threading through two adjacent fabric channels; the frame supported by a base member resting on the ground; a second metal frame member for receiving the distal ends of each of the arm members of the first metal frame member, at a level so that the bulk bag is supported by the arm members; bulk material to be poured into the supported bulk bag, to a level that the bag is substantially filled and no longer requires the support of the frame, so that the frame can be removed and positioned onto the next pair of fabric channels to fill the next empty bag.

A portable, water-filled barrier system includes a barrier internally divided into cells that emulates a section of a sandbag dike or wall. Automatic valves can seal openings between the filled cells, so that a punctured cell will not cause cells below and behind to deflate. In embodiments the barrier can be initially filled with air, positioned, and then filled with water while the air escapes through a pressure valve. The system further includes a base with water inflatable front and back panels. The side panels and bottom panel of the base can be water inflatable or flat. The base can be used to increase friction with the ground, protect against stones, and/or to support a leveling wedge or leveling material such as sand or spray foam when located on a sloped surface. A plurality of adjacent bases and barriers can provide an extended barrier system.

An inflatable flood defence structural unit is described for creating an inflatable flood defence arrangement. The unit comprises at least one inflatable chamber comprising a front wall and a rear wall which extend in a substantially parallel orientation. At least one of the front and rear walls provide a water barrier, and a first and second end wall are arranged to couple the front and rear walls together at a respective first and second end of the front and rear walls. The unit further comprises a first inflatable buttress which is rigidly bonded at a proximal end thereof to the rear wall of the chamber, proximate the first end of the chamber and which extends in a direction which is away from the chamber, and a second inflatable buttress which is rigidly bonded at a proximal end thereof to the rear wall of the chamber, proximate the second end of the chamber, and which similarly extends in a direction which is away from the chamber. The unit further comprises a fastening arrangement disposed upon at least one of the first or second buttress for fastening the first and second buttress to a second and first buttress respectively, of a further structural unit to create the flood defence arrangement.

A stand-atone flood barrier apparatus that bolts to the ground through anchor bolts that connects with other stand-alone flood barrier apparatus to make a circuit to protect a person's desired location they wish to protect against flood waters such as crop fields. The stand-alone zigzag sheeting then is protracted from the stand-alone base unit and opened out for the end of sheeting to then fix into the retractable/expandable floor grip which is to be fully extended from the main unit which the zigzag sheeting fixes into. The stand-alone apparatus & zigzag sheeting can be retracted back into the stand-alone main unit and locked for further use in the future. Also can be detached from the anchor bolts and stored or used elsewhere. Underneath the stand-alone main unit there is a spike running through the center to keep away surface water. There is also a soft large rubber strip along the full base of the stand-alone unit to tolerate any undulations in the earth beneath the stand-alone apparatus. The stand-alone can be reused until sufficient use makes it no longer capable of propelling water from the desired locations you wish to protect & recycled.
