River diversion and blocking device for water conservancy engineering and its application method

Abstract

The invention relates to municipal engineering, in particular to a river channel diverting and blocking device for water conservancy engineering and a method for using the same. Adjust according to the water level demand, and then control the water storage capacity. After the dam body is raised, it is supported by the dam body support device, and a gap is formed between the river bed and the lower end of the dam body. The pressure of the water flow increases, which in turn leads to an increase in the speed of the water flow, which can achieve a good dredging effect. The bottom of the dam body and the river bed are not fixed, which is convenient for removal and maintenance. The dam body includes a support tube, and there is a filling core in the support tube. By controlling the weight of the filling core , can control the difference between buoyancy and gravity, and then control the stability of the dam body, set up a corrosion-resistant layer and a waterproof layer, which has a good waterproof and anti-corrosion effect and a long service life.

Description

technical field [0001] The invention relates to municipal engineering, in particular to a river diversion and blocking device for water conservancy engineering and a method for using the same. Background technique [0002] The river course is an important part of the urban water system, and it has the functions of landscape, sewage discharge, flood control, and irrigation. Due to its important role, the urban river course has received extensive attention. Dredging, water storage, and water level adjustment are common management forms of urban river courses. [0003] Most of the existing urban rivers have a width of 10-70m. Building protective barriers on both sides of the river can achieve the effect of preventing soil erosion, reduce the sediment content of the river, and facilitate the planting of green plants. [0004] In order to facilitate the adjustment of the storage water level, people have developed rubber dams and hydraulic lifting dams, which are placed in the mid...

AI Technical Summary

Problems solved by technology

[0004] In order to facilitate the adjustment of the storage water level, people have developed rubber dams and hydraulic lifting dams, which are placed in the middle of the river to achieve the purpose of controlling the water level and blocking pollution. The dam foundation is fixed, and the water level control height is limited. The control water level is generally within 1.5m, and it is inconvenient to dredge. The hydraulic lifting dam drives the dam slab to turn over through the hydraulic cylinder. Inconvenient for dredging
