FIELD: hydraulic building of shore-protective structures to be erected in river, canal bed liable to erosion or other structures. ^ SUBSTANCE: flood control method involves assembling collapsible structure along the full river bank, wherein the collapsible structure includes spacing members formed of metal-plastic pipe provided with filler; connecting spacing members to create triangular prism by connecting thereof to transversal reinforcement by means of yokes so that joints are created; imparting polygonal shape to head slope from upstream side to increase vertical hydrostatic water pressure component and to provide structure shear resistance; laying water-tight fabric on spacing members from upstream side thereof so that elongated apron is created; arranging water discharge ditch from downstream side and providing the ditch with pump for filtered water accumulation and discharge. Spacing member installation has increased density at upstream side and spacing between said spacing members provide tight fitting of water-tight fabric. Lower layers are formed of members having thicknesses exceeding that of upper layer. ^ EFFECT: increased efficiency and reliability of shore-protective structure to protect thereof against flooding and emergency water rise caused by repair works, increased service life and decreased time of structure erection. ^ 3 cl, 5 dwg |
