Description

Hydraulic dam with arrange husky structure

Technical Field

The invention relates to the technical field of water conservancy facility construction, in particular to a hydraulic dam with a sand discharge structure.

Background

A dam is a water retaining structure for intercepting river channel water flow to raise water level or regulate flow, and is used for flood control, water supply, irrigation, hydroelectric generation, shipping improvement and the like. Common dams include rubber dams, sluice gates and flap gate dams.

Over time, the upstream face of the dam deposits a lot of sand and stones. The fence sluice is through raising the gate, turns over the board gate dam and arrange husky through the dam facing crouching, and the fence sluice all can waste a large amount of water with the row's of board gate dam husky mode this kind. The rubber dam is made of rubber, when too much sand and stones exist, the rubber dam is not easy to rotate, sand discharging is difficult, and if sand discharging is not thorough, water leakage can be caused at the bottom of the rubber dam.

The rubber dam is limited by the material, so that the rubber dam is poor in impact resistance, is easy to be scratched by a sharp object and is easy to crack; although the water gate is firm and durable, the construction period is long and the cost is high; and turn over board dam and be prefabricated type, construction cycle is relatively short, and the material is firm, consequently, the application is the most extensive in recent years. However, the flap gate dam has a very big disadvantage that water leakage occurs when the flap gate dam rotates. The water leakage can affect the water storage effect, and the biggest problem is that the flap gate dam can not normally rotate due to the intrusion of sundries. And in practical application, the fixed-size flap gate dam cannot meet the use requirements, especially in areas with large precipitation or areas with unstable precipitation, for example, once the precipitation is increased suddenly, the water storage depth of the fixed-size flap gate dam cannot be changed, after the height of the flap gate dam is exceeded, water leaks from the top of the dam, so that the flood control effect cannot be achieved, water cannot be stored to the maximum extent, and water waste and flood disasters are caused.
