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 turned towards a dry side of the protective bank. Between the surface (2) and the bank member (1) there is applied a device (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 device (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.
In a liquid-retaining protective bank having a barrier member for damming a liquid, said barrier member being adapted to abut a substrate surface, said protective bank having a first long side edge and an opposed second long side edge turned towards a dry side of the protective bank, the improvement comprising draining means between said substrate and said barrier member, said draining means extending axially along said protective bank and being adapted to drain flood liquid leaking under said barrier member from said first side edge, and for keeping the area on the bottom side of said barrier member extending from said long side edge of said draining means substantially at or about atmospheric pressure to thereby obtain a maximum pressure differential in relation to hydraulic pressure of said liquid, the hydraulic pressure being adapted to keep said protective bank sealed against said substrate surface.
In a method for forming a liquid-retaining protective bank having a barrier member abutting against a substrate, said protective bank having a first long side edge turned towards a flood side and an opposite second long side edge turned towards a dry side of the protective bank, the improvement comprising applying drainage means between the surface and said member and which extends axially along said bank to drain away liquid leaking under said drainage means from a liquid side of said protective bank so as to keep the area on the bottom side of the member extending from the long side edge of the draining means closest to the liquid side to the dry side, substantially at or about atmospheric pressure in order to obtain a maximum pressure differential in relation to a hydraulic pressure of said liquid, said hydraulic pressure being adapted to keep the protective bank sealed against the surface.
