hydraulic engineering, fight against floods and spread of water and other liquids over various surfaces. SUBSTANCE: bank protecting against liquid includes part bordering on surface, for example, ground on which vertical force pressing it against this surface and holding it in place acts. Bank includes edge of first long side facing spread of liquid and edge opposite to first one and facing dry side of protective bank with second long side. Facility, for instance mat, to remove liquid that can seep out under mentioned above part on side of spread is so arranged between surface and mentioned part of bank in axial direction along bank that section of lower side of this part lying between edge of long side of facility to remove liquid which is nearest to side of spread is kept under atmospheric pressure or under pressure close to atmospheric one to obtain maximum pressure difference with respect to hydraulic pressure with which tight pressing of protective bank against surface is ensured. EFFECT: erection of protective bank reliably held in place under conditions of water seeping out under it. 8 cl, 8 dwg
