Description

Stifled cistern is prevented to hydraulic engineering

Technical Field

The invention relates to the technical field of hydraulic engineering, in particular to an anti-blocking water reservoir for hydraulic engineering.

Background

In the water conservancy work progress, often set up the cistern and save and utilize the natural water resource to this can reduce construction cost, however silt content in the natural water resource is great, and the drainage pipe mouth of pipe can appear often by the phenomenon of silt jam, causes very big influence to the drainage water, and the long-time deposit is difficult to the clearance at the silt of drainage pipe mouth of pipe department, influences the construction progress.
