Abstract:
A damming device for forming a barrier between a wet or flood side and a dry side of said device, comprising:an anchoring board for resting on a surface in a generally horizontal orientation, said anchoring board having top and bottom sides, and side, front and rear edges; hydrostatic anchoring means associated with said board for anchoring said device to said surface by hydrostatic pressure, said anchoring means comprising in combination a barrier for limiting liquid seepage from said flood side underneath said anchoring board and draining means for maintaining a pressure differential between the hydrostatic pressure acting on said top side of said anchoring board and a substantially atmospheric pressure acting on the bottom side thereof by draining liquid away from the underside of said anchoring board for discharge at said dry side, said draining means comprising one or more channels at said lower side of said anchoring board; a liquid impervious damming board fastened to said anchoring board for orientation in an upright position for retaining said liquid on said wet side and preventing passage of said liquid from said wet side to said dry side, said damming board having upper, lower and side edges; at least one connecting means between said anchoring board and damming board for holding said damming board in said generally upright position; wherein said at least one connecting means consist of one or more tensile force carrying connection devices which extend between the wet side of the damming board and the anchoring board, wherein said anchoring board and said damming board are interconnected in a liquid-proof way along a connection line which extends between a lower edge of the damming board and the top side of the anchoring board, and wherein the one or more tensile force carrying connection devices each comprise a generally plate-like web; at least two of said tensile force carrying connection devices comprising two end surfaces each one of which includes a top part and an upright edge connected in a liquid-proof way to the damming board along said upright edge, as well as the anchoring board along a laying edge, all while forming a construction which is shovel-like and which, in an active state, opens towards the wet side; wherein the damming board in a plane, tension-free state has oblique side edges which mutually diverge in an upward direction and which are connected to said end surfaces whereby said end surfaces are maintained in a state diverging from each other in an upward direction, and that a loading mechanism extends between the side edges of the damming board for reducing, when required, the distance between the side edges and thereby the top parts of the end surfaces by causing the damming board to bow convexly towards the wet side.
