摘要
FIELD: environment protection.;SUBSTANCE: invention is related to environment protection improvement of territories and may be used as erosion-preventive protection of slopes and other objects. Device for erosion-preventive protection of steep slopes includes drop spillways made in the form of walls and arranged at the slope across surface drain. Vertical side of the said walls serves as spillway, the wall being assembled from interconnected gabions oriented along direction of drain. Drop spillways are arranged in their cross section as curvilinear trapezoid, with its concave curvilinear side oriented to the side of supported soil. Wall is assembled from interconnected parabolic gabions. Concave curvilinear side of trapezoid is described with equation of hyperbola where X, Y - abscissa and ordinate of hyperbola, respectively, 0.3≤X≤B; H - height of drop spillway, m; B - width of drop spillway basis, B=(1÷1.5)H.;EFFECT: increase in efficiency, effectiveness and reliability of slopes protection against water erosion and durability of structure service life.;2 cl, 4 dwg
