FIELD: hydraulic engineering.
SUBSTANCE: invention relates to hydraulic engineering, in particular, to hydrosystems with ground dams and spillways. Purpose of the invention is to increase the throughput capacity of the filter spillway and to reduce the volume of the ground dam by increasing the area of the water intake of the filter spillway using reinforced concrete corner retaining walls on the crest and in the base of the lower slope of the ground dam. Ground dam includes a body made of water-permeable material and an anti-filtration screen. On reinforced concrete angular support wall with slots both in foundation and in vertical plates there is a reinforced concrete angular wall on the ridge of the screen. In the base of the dam at the lower slope there is a reinforced concrete angular retaining wall with slots in the vertical plate.
EFFECT: invention makes it possible to reduce the cost of the hydraulic power plant by reducing the volume of the soil dam, as well as due to the abandonment of the shore spillway or its reduction.
