A wind and water barrier system for the protection of property is provided, wherein the barrier system is embodied in a singular device. The systemic device includes a flexible partitioned tube, each partition fillable with water to provide a flood barrier along a supporting surface around the property. A plurality of connections points is provided along a first longitudinal segment of the flexible tube, the connection points are anchored to the supporting surface. Along a second longitudinal segment a flap interfaces with an apron and is connected thereto by way of attachment points. The apron extends from the attachment points so as to be movable between a furled storage condition and an unfurled operable condition placed or installed over the property as a wind barrier. The line of force through the unfurled planar apron may intersect the interface of the stakes, the supporting surface, and the connection points.

A geotextile tube includes a bag unit, an extending unit, a main stitch seam, and two auxiliary stitch seams. The bag unit includes a tubular wall and an end wall cooperatively defining a filling space. The extending unit includes two extending parts respectively extending from opposite lateral sides of the end wall and each defining a buffering space. The main stitch seam extends from one of the extending parts to the other one of the extending parts for sealing the filling space. The auxiliary stitch seams intersect the main stitch seam, and are respectively disposed at the lateral sides of the end wall such that the end wall is substantially flat. Each auxiliary stitch seam separates an adjacent buffering space from the filling space.

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 portable, water-filled barrier system includes a plurality of water-fillable modules, each module being internally divided into cells that emulates a section of a sandbag dike or wall. Adjacent modules are interconnected by fastening mechanisms, such as loops attached to fronts or sides of the modules and connected by straps or clamps. 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. A manifold can be used to simultaneously fill a plurality of cells. A flexible sheet can be installed beneath and in front of the assembled barrier so as to inhibit leakage of water under or between the cells.

System for preventing the leakage of liquid from an outdoor work-site around the perimeter of the work-site includes a load-supporting surface having at least two adjacent mats and a plurality of berm members configured to be disposed around the perimeter of the load-supporting surface.

An inflatable flood barrier includes a board having a side plate and a peripheral plate attached to the side plate. The board being provided with a charging port, the peripheral plate has rounded corners, and the side plate has corner portions. The rounded corners and the corner portions are positionally corresponding. The corner portion has guiding grooves. A flexible seal embraces at least a part of the peripheral plate and has an internal channel, a gas inlet and a gas discharging port. When the flexible seal is inflated at the internal channel, a watertight combination between the inflatable flood barrier and a contacting surface of a gate it protects is achieved. The inflatable flood barrier is structurally simple, watertight, convenient to use and store, apparently pleasing, and functionally versatile.

According to the present invention there is provided a liquid retention device comprising: a braced frame mountable on foundations in a plurality of locations, in which said device comprises a base section and at least one upstanding support, and in which said brace further comprises height-adjusting means for adjusting the height of said frame, and in which said device further comprises a face supported by said frame, in which said face is inclined at an angle to the at least one upstanding support, wherein said face is covered by a least one detachable mat.

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.

Compressible fluid-impermeable berm devices that self-adhere to surfaces such as ground, pavement and floors are disclosed. The compressible containment berm devices include one or more compressible containment wall sections formed from a flexible shell and a compressible filler material. A pre-applied adhesive layer at least partially covers the underside of each compressible containment wall, and is used to adhere and seal the containment wall to the containment surface. Corner joints may be used to connect the compressible containment wall sections together to thereby form the berm devices with a closed perimeter that contains leaks and spills. The compressible fluid-permeable berm devices can be easily removed or repositioned after use leaving little or no adhesive residue.
