FIELD: construction.SUBSTANCE: invention relates to hydraulic engineering construction and can be used as protection against floods in case of emergency situations, when conducting the rescue and recovery operations, as well as in case of capital construction in close conditions. Protective structure consists of triangular trusses assembled from the spacer tubes by fixing them in junction points and elongated impervious blanket. The upper slope is assembled from assembled flat slabs with the connected locks and long side oriented along the protective structure and with shear of vertical joints. Waterproof material is laid under the framework of protective structure on the prepared soil of foundation and impervious blanket is arranged in front of it. Waterproof material is sprinkled on top with soil. As the distance from the upper slope to the outer slope increases, the height of powdering layer h reduces. Triangular trusses are mounted in the soil by means of anchors. Height of powdering layer depends on the water head H and in the upper point h=(0.2÷0.4)H. Flat slabs are made of plastic or composite materials.EFFECT: invention provides the increased reliability for protection of the shores of river beds and durability of the protective structure.4 cl, 5 dwg |
