Service spillway of hpp dam // 2639046
FIELD: construction.SUBSTANCE: invention can be used to regulate the water level in water bodies that have a threat of flooding, for example, on the rivers Zeya, Amur and other similar reservoirs. Also for the transfer of flood waters from the Zeya Reservoir to the downstream to achieve 310 meters A.S.L. by 1 August so that the spillways do not cause damage to the base of the Zeya Dam. The service surface spillway at the Zeya HPP is supplemented by at least one classical aqueduct. The aqueduct is functionally a continuation of the service surface spillway. The conjugation with the aqueduct is made above the springboard of the service surface spillway. The aqueduct, from conjunction with the tray of the service surface spillway before reaching the horizontal position of the aqueduct, has smooth curvature, allowing the watercourse to undergo without spray, i.e. smooth flow to the outlet, which is made at a considerable distance from the dam base. The aqueduct is throughout rigidly fixed to the bearing supports. The aqueducts themselves are made of stainless steel, or of any known non-corrosive metal, or metal with corrosion-resistant coating and/or concrete and/or reinforced concrete and are solid or modular or precast solid. The aqueducts in the walls have branch pipes that are installed in the walls of the aqueduct at an angle 45°±25°. The branch pipe is curved relative to the aqueduct across the river, water enters the branch pipe at an angle 45°±25°, but exits from the branch pipe at an angle 80°±25°. The branch pipes are installed in such a way that the water jets emanating from neighbouring aqueducts collide with each other, and the water energy is quenched and its speed slows down. The speed of the water flow of the falling water and the water flowing through the aqueduct is 30-50 m/sec. If this stream is not retarded to the river current (2-3 m/s), then this stream will bring considerable destruction on the shoreline of the river, and also threaten the vessels in the riverbed.EFFECT: rational distribution of water resources and prevention of floods, lowering the level of reservoirs and protecting the dam base from destruction.7 cl, 2 dwg
