Waterproof drainage device for hydraulic engineering construction

Abstract

The invention discloses a waterproof drainage device for hydraulic engineering construction. The waterproof drainage device comprises a soft coiled pipe; connecting pipes are transversely and evenly arranged on one side of the soft coiled pipe, an inserting pipe is arranged in each connecting pipe, a first hose is arranged on each inserting pipe, a sewage pump is arranged at one end of each firsthose, a second hose is arranged at the drainage end of each sewage pump, water suction openings are symmetrically formed in the two sides of the soft coiled pipe correspondingly, a stirring spring isarranged in the soft coiled pipe, a power cylinder is arranged at one end of the soft coiled pipe, a connecting rib is arranged at one end of the stirring spring, and openings are symmetrically formedin the two sides of the power cylinder correspondingly. Under the clockwise rotation of the stirring spring, water in the soft coiled pipe is twisted rightwards, so that the washing effect on the soil fragments is achieved, the scattering effect of the soil fragments in the water is enhanced, water plants and soil fragments are spirally brought into the power barrel, and after a period of time, the water plants and the soil fragments can be taken out of the power barrel through the openings; and therefore amount of the water plants and large soil blocks sucked by the first hose can be effectively reduced, the sewage pump is protected.

Description

technical field [0001] The invention belongs to the technical field of water conservancy project construction, and in particular relates to a waterproof and drainage device for water conservancy project construction. Background technique [0002] Water conservancy projects are a general term for various engineering constructions built to control, utilize and protect surface and underground water resources and the environment. Projects built to eliminate water damage and develop and utilize water resources are divided into flood control projects and farmland projects according to their service objects. Water conservancy projects, hydropower projects, waterway and port projects, water supply and drainage projects, environmental water conservancy projects, tidal flat reclamation projects, etc. [0003] As a kind of water conservancy project, water conservancy cofferdams are erected on the river bed with cofferdam slabs to open an area on the river bed where infrastructure can b...
