During flooding, water (not illustrated) above the support plate 13 press the support plate down and creates an increased sealing pressure on the seal 12. Thus there is no need for the water-proof canvas 16 which is illustrated in FIG. The surface of the foundation 18 is fairly flat, which ensures a good sealing between the support plate 13 and the foundation. The seal 12 is located on the foundation 18. The positive sealing pressure on the seal 12 is caused by a levering action due to the weight of the wall 5 and the hinge 22, 24 to the permanent foundation 18. The seal 12 is located under the support plate 13, close to the edge 54 of the support plate 13 which is distal to the wall 5. The foundation 18 will have to be built prior to the flooding, in an area in which flooding is expected, and at a place in which it is suitable to erect the flood barrier. This is achieved by the hinge bracket 23, which via a curved portion 24 is hinged to a hinge pin 22 of the foundation 18. 3, the support plate 13 is adapted to temporarily attachment to a permanent foundation 18 in the ground 2.
Flood barrier for tents portable#
The hinge between the wall and the basis makes the portable flood barrier section collapsible. It is thereby provided a portable flood barrier section for which water leakage underneath the flood barrier section and the ground is prevented or is only small. The flood barrier section is adapted to, prior to flooding, to expose the seal to a positive sealing pressure exceeding a pressure caused by the weight of the flood barrier section. The portable flood barrier section is provided with a seal which in the erected position of the flood barrier section is located between the flood barrier section and the ground.
The invention thus relates to a portable flood barrier section to be located on a ground to form a barrier against flooding water, comprising an erectable wall which along one of its edges is hinged to a basis, the hinge enabling a rotating erection of the wall from an essentially horizontal position to an erected position, and a flexible or rigid tie which extends from the basis to the wall on the flooded side of the wall, to prevent an erection of the wall beyond the erected position.
