A water-fillable flood control device is provided that consists of a waterproof bag with a friction causing outer surface and having a mouth that can be closed with a waterproof seal after filling the bag with water. The bag can be filled by one person at a flood site using a filling/form sleeve and locally-available water. It is not necessary to fill the bag with sand, or add chemicals. The friction causing surface may be achieved by any means or method so long as the purpose is to hold the device in place for facilitating the stacking of a plurality of devices on top of each other to form a stable water control structure without the need for external supports.

The invention discloses a gyrating drilled shaft provided with an aeration ridge. The invention is characterized in that the gyrating drilled shaft is provided with an aeration ridge on the wall surface at the middle lower part of the drilled shaft section, the aeration ridge is formed by gradually shrinking the drilled shaft connected with the upper flat section of a flood discharging tunnel from the middle part to the middle lower part and then suddenly expanding the wall surface, and at least two aeration holes are distributed on the annular aeration ridge formed by the sudden expansion, each of the aeration holes is spliced with a vent pipe communicating with the atmosphere. The vent pipes can be selectively buried on the outer side of the gyrating drilled shaft. The gyrating drilled shaft disclosed by the invention enables near-wall water layers at the lower reaches of the aeration ridge to become into aerated water flows, thereby increasing the flow cavitation number, playing the effects of air entrainment and cavitation prevention, preventing the overflowing section at the middle lower part of the drilled shaft from being damaged by cavitation erosion, and ensuring the safe flood discharging operation of the gyrating drilled shaft.

Disclosed is an expansion-sealed flood control gate, comprising a water board, a frame structure, two symmetrical constraint tracks, at least one encased expandable sealing tube, and a plurality of adapters. A U-shaped slot is formed between the two symmetrical constraint tracks for plugging in the water board. Each constraint track has a U-shaped expanding compression chamber connecting from one end to the other end to accommodate the tube inside. The adapters are connected with the open ends of the tube and fixed on the constraint tracks at the connected ends. Accordingly, there can be effectively repelled floods that the tube with the characteristics of active filling and uniform packing stress have the higher geometric tolerance, even if the slits between the water board, the constraint tracks and ground emerge the unexpected geometrical change, the encased expandable sealing tubes are ballooned to mend the slits.

A sectionalized flood control barrier (10) for mounting on top of a levee or a river bank to prevent flooding. The barrier (10) consists of a footing (20) with a series of support channels (24) that are butted end to end attached to the footing. The support shells are sealed watertight at the interface with each other and also to the footing. A series of primary channel bridge assemblies (32) and secondary channel assemblies (46) are disposed within the support channels (24) and are also butted end to end. Wind protectors (60) contiguously engage each support channel (24) and rest upon the footing for diverting the wind over the barrier. Stepped fastening risers (62) are attached to the footing on each end and over the channel assemblies, and wind protectors hold them securely in place.

A damming device for forming a liquid-damming protective bank comprises at least one first board (1), in the active state laying, intended to be urged by the liquid against the surface and thereby anchoring the device, as well as at least a second board (2), in the active state up-right, intended to dam the liquid. There are liquid-draining means (5) on the bottom side of the anchoring board (1). Devices (9, 9') act between the two boards (1, 2) with the purpose of inhibiting tilting of the damming board (2) from the active position in the direction towards the dry the side, when liquid simultaneously affects the anchoring board (1) with a vertical force and the damming board (2) with a horizontal force.

A flood barrier system for temporarily sealing an opening in a wall structure against the inflow of flood waters. The system comprises a plurality of elongated, horizontally disposed barrier elements of a length somewhat greater than the width of the opening. The barrier elements are stacked vertically, one upon the other against the outer face of the wall structure. End clamps engage opposite ends of the individual barrier elements to press them snugly against the outer surface of the wall, providing seals along the opposite vertical side edges of the opening. The barrier elements incorporate a unique interlocking configuration that simplifies and expedites assembly of a flood barrier and strengthens the integrity of the assembled structure. Improved and simplified arrangements are provided for clamping the ends of the barrier elements and for applying downward pressure to the assembled barrier. The resulting structure is more economical to provide and maintain and is more quickly assembled in the often emergency circumstances in which it is required.
