SELF CLOSING FLOOD BARRIER AND METHOD FOR PROTECTING A HINTERLAND USING SAME.

摘要

The invention relates to a self closing flood barrier for protecting a hinterland against floods, wherein the flood barrier comprises a chamber comprising a first side wall (20) and a second side wall (21), a water inlet for letting in water, a single support block arranged on the first side wall (21), and a dam wall member up and down movably arranged in the chamber. The dam wall member comprises a retaining wall (4) for avoiding water to flow to the hinterland, a forcing element (4, 5a, 5b) for causing an upward movement of the dam wall member, and a blocking element (5b) for providing a blockade for limiting the upward movement, the blocking element comprising an inclined surface (16). The support block comprises an inclined surface (17) against which the inclined surface (16) of the blocking element (5b) acts in a closed state of the flood barrier. Due to the orientation of the angled wall of the support block, the blocking element is forced to move sideward and thereby a lateral force is created forcing the dam wall member to one side of the chamber.
