Double-layer energy dissipation and sand collection channel and method

Abstract

The invention relates to a double-layer energy dissipation and sand collection channel and method. A flow channel is included, one end of the flow channel is communicated with a sand basin, the sectional area of the sand basin is larger than that of the flow channel, a partition plate, a descending plate, a pore plate and a flip bucket are sequentially arranged in the flow channel, the end, connected with the pore plate, of the descending plate inclines downwards, and the other end of the flow channel is connected with a sand guide bucket and a sand blocking bottom bucket. Sediment in a river channel is collected in a centralized mode through energy dissipation measures, water is purified, harm to the environment due to the sediment problem is reduced, and the hydro-junction efficiency is improved.

Description

Technical field [0001] The present invention belongs to Patent Hydraulic Engineering set new sand energy dissipation technology, and particularly relates to a medium-sized one for before water conservancy, sandy river upstream, flash-prone areas downstream river, settling can be widely used in various Shen Shi, purify large diameter water quality suspension occasion. Background technique [0002] At present, the river sediment how to correctly and efficiently processed to purify water, reduce silt brought by the various hazard is a difficult and vital water projects inside the issue. With the change in the flow velocity of the different positions in the process of deposition of sediment found in the study, because the water flow is too complicated, leading to sediment deposition can not be unified in one place, generating clean up sediment complex and difficult problem. At the same time due to the small particle size of sediment, Trash traditional structure can not be stopped, so...

AI Technical Summary

Problems solved by technology

In the process of studying the deposition of sediment at different locations with the change of water flow velocity, it is found that due to the complicated flow of water bodies, the sediment cannot be deposited uniformly in one place, resulting in complex and difficult problems of sediment cleaning

At the same time, due to the small particle size of the sediment, the traditional dirt blocking structure cannot stop it, so that it can enter the water conservancy engineering facilities and cause wear and tear of the water conservancy engineering equipment
