A portable flood barrier section is located on a ground ( 2 ) to form a barrier ( 3 ) against flooding water ( 4 ), comprising an erectable wall ( 5 ) which along one of its edges ( 6 ) is hinged to a basis. The hinge ( 7 ) enables a rotating erection (A) of the wall ( 5 ) from an essentially horizontal position to an erected position. A flexible or rigid tie ( 8, 9 ), which extends from the basis to the wall ( 5 ) on the flooded side ( 10 ) of the wall ( 5 ), prevents an erection of the wall ( 5 ) beyond the erected position. A seal ( 12 ) is in the erected position of the flood barrier section ( 1 ) located between the flood barrier section and the ground ( 2 ). The flood barrier section ( 1 ) is adapted to, prior to flooding, to expose the seal ( 12 ) to a positive sealing pressure exceeding a pressure caused by the weight of the flood barrier section ( 1 ). The invention also relates to a flood barrier ( 3 ) comprising flood barrier sections ( 1 ). |
