Lifting submerged dam

Abstract

Disclosed is a lifting submerged dam. The lifting submerged dam is transversely arranged between rocks of two shores and is arranged in a multiple segment manner and comprises a concrete preformed groove, a water baffling dam body, a buoyancy tank, two limit cover plates, a water feed and drainage valve and an exhaust pipe. The concrete preformed groove is a cuboid transverse groove digged in the riverbed; the water baffling dam body is in a cuboid double-layered steel plate n-shaped structure, the buoyancy tank is in a prefabricated tank structure, and the water baffling dam body is fixed to the middle of the buoyancy tank; the water feed and drainage valve is located at the bottom of the buoyancy tank, the exhaust pipe is located at the top of the buoyancy tank, and the two limit cover plates are fixed to the riverbed of two sides of the water baffling dam body at the top of the concrete preformed groove. The lifting submerged dam is reliable in quality and easy to construct; in the water baffling period, the water baffling dam body is lifted to baffle water and bank up the water level; before the flood, the water baffling dam body is sunk and hidden into the preformed groove of the riverbed, and flood release is free of blockage; the problems of river water level and amount adjustment and control in the dry season can be solved through low cost, and the river ecological landscaping effect can be improved.

Description

technical field [0001] The invention relates to a retaining dam in hydraulic engineering, in particular to a liftable submersible dam. Background technique [0002] In recent years, the demand for comprehensive improvement of rivers for the purpose of water environment and water ecological protection, as well as landscape and recreational environment creation has been increasing. Mountainous rivers in my country have large flood flow, deep water and wide water surface during the flood season, while in non-flood season, the flow is small, the water is shallow and the water surface is narrow, which affects the viewing of the river landscape. In order not to impede flood flow, rubber dams are usually used to increase the water level in non-flood seasons. However, when mountainous rivers are flooded, they tend to move more and larger sandstones are easy to damage the rubber dam pockets. Therefore, rubber dams are not suitable for mountainous rivers in non-flood seasons. water. ...
