A flood defence assembly comprises a support member (2) formed from steel or other rigid material and having a sleeve portion (4) that is adapted to be slidably mounted on a bollard (6). Bollard (6) is set into the ground (8) to an appropriate depth adjacent a body of water that is susceptible to flooding. The support member (2) comprises first and second support panels, which form a slot (14) into which a panel member (16) is slidably mountable. Support member (2) is also provided with a plurality of brackets (19) for supporting restraint members (20) in the form of metal tubes or other members of similar strength. Buttress members (22) are disposed between the sleeve portion (4) and the back panel of support members (2). A rubber sheet (24) can be removably placed along the ground (8) at the point where the panel member (16) contacts the ground (8). When a body of floodwater (26) rises, the weight of the floodwater (26) deforms panel member (16) and pushes the panel member (16) downwardly onto rubber sheet (24) and into the rubber seal members (not shown) disposed in slot (14). The restraint member~s (20) support the panel members (16) at the maximum deflection of panel member~s (16).

Ensemble anti-inondations comportant un organe de support (2) fabriqué en acier ou un autre matériau rigide et possédant une partie de manche (4) qui est adaptée pour être montée de façon à pouvoir coulisser sur une borne (6). La borne (6) est posée dans le sol (8), sur une profondeur appropriée, à côté d~une étendue d~eau sujette aux crues. L~organe de support (2) comporte un premier et un deuxième panneaux de support lesquels forment une encoche (14) dans laquelle un organe de panneau (16) peut être monté de façon à pouvoir coulisser. L~organe de support (2) est aussi doté d~une pluralité de supports (19) pour soutenir des organes de retenue (20) sous la forme de tubes métalliques ou d~autres organes de résistance similaire. Des organes de contrefort (22) sont disposés entre la partie de manche (4) et le panneau arrière des organes de support (2). Une feuille de caoutchouc (24) peut être placée de façon amovible le long du sol (8) au point où l~organe de panneau (16) entre en contact avec le sol (8). Quand une étendue d~eau est en crue (26), le poids de ces eaux (26) déforme l~organe de panneau (16) et pousse ce dernier vers le bas sur la feuille de caoutchouc (24) et dans les organes d~étanchéité en caoutchouc (non illustrés) disposés dans l~encoche (14). Les organes de retenue (20) soutiennent les organes de panneau (16) au fléchissement maximum de l~organe de panneau (16).
