Abrégé

The present invention relates to a self-raising wave barrier for providing an alleviation of a load due to wave action from a body of water on the side of the wave barrier remote from the body of water. The barrier includes a series of barrier assemblies providing alleviation of the load due to the wave action. Each barrier assembly includes a holder for a wave barrier element which is anchored to a bottom of the body of water or a surface adjacent to the body of water, a wave barrier element arrangeable movably over a path of movement in the holder between a lower rest state and a higher active state, and holding means for holding and/or stopping the wave barrier element in the higher active state.

The present invention relates to a self-raising wave barrier for providing an alleviation of a load due to wave action from a body of water, such as a sea, on the side of the wave barrier remote from the body of water, the wave barrier comprising: - a series of barrier assemblies for providing the alleviation of the load due to the wave action, each barrier assembly comprising: - a holder for holding a wave barrier element which is anchored to a bottom of the body of water or a surface adjacent to the body of water, - a wave barrier element arrangeable movably over a path of movement in the holder between a lower rest state and a higher active state, - holding means for holding and/or stopping the wave barrier element in the higher active state, wherein - the respective wave barrier elements of the series of barrier assemblies operate in the active state for the purpose of breaking the wave action providing the alleviation of the load due to the wave action on the basis of a situationally predetermined ratio of wave barrier elements and throughflow space therebetween.

Abrégé

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.
