A liquid-damming protective bank comprises a member abutting against a surface upon which a vertical force acts with the purpose of pressing and anchoring the same against the surface. The bank member has a first long side edge turned towards a flood side and an opposite long side edge fumed towards a dry side of the protective bank. Between the surface (2) and the bank member (1) there is applied means (12) extending axially along the bank, e.g. a mat, the purpose of which is to drain away flood liquid possibly leaking in under the member from the flood side so as to keep the area on the bottom side of the member elongating from the long side edge of the draining means (12) being closest to the flood side to the dry side, at or close to atmospheric pressure in order to obtain a maximum pressure difference in relation to the hydraulic pressure keeping the protective bank sealing against the surface.
Une digue protectrice de retenue d'eau est constituée d'un élément venant buter contre une surface sur laquelle s'exerce une force verticale de sorte que celui-ci soit poussé et ancré contre ladite surface. L'élément digue présente un premier bord latéral long tourné vers un côté eau et un bord latéral long opposé tourné vers un côté sec de la digue protectrice. Entre la surface (2) et l'élément digue (1), on a prévu un moyen (12) s'étendant axialement le long de la digue, tel qu'un matelas, dont le rôle est de drainer le liquide susceptible de s'échapper du côté eau, par le dessous de l'élément, de sorte que la zone située côté fond de l'élément s'étendant depuis le bord latéral côté eau du moyen de drainage (12) le plus près du côté eau jusqu'au côté sec, soit maintenue à la pression atmosphérique ou à une pression proche de celle-ci et qu'une différence de pression maximum soit obtenue par rapport à la pression hydraulique maintenant l'étanchéité de la digue de protection contre la surface.
