CA 2441037

The invention relates to a portable flood barrier section (1) to be 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).

L'invention se rapporte à une section de barrière anti-inondation portable (1) conçue pour être disposée sur le sol (2) de manière à constituer une barrière (3) contre des eaux d'inondation (4) et comportant une paroi déployable (5) qui est articulée par rapport à une base le long d'un de ses bords (6). L'articulation (7) permet de redresser par rotation (A) la paroi (5) à partir d'une position sensiblement horizontale jusqu'à une position érigée. Un lien souple ou flexible (8, 9), qui s'étend à partir de la base de la paroi (5) sur le côté inondé (10) de la paroi (5), empêche le redressement de la paroi (5) au-delà de la position érigée. Un joint (12) est disposé, dans la position érigée de la section de barrière anti-inondation (1), entre ladite section de barrière anti-inondation et le sol (2). Cette section de barrière anti-inondation (1) est conçue pour que, avant l'inondation, le joint (12) soit soumis à une pression de scellement positive supérieure à la pression provoquée par le poids de la section de barrière anti-inondation (1). La présente invention se rapporte également à une barrière anti-inondation (3) comportant de telles sections (1) de barrière anti-inondation.
