Riverway diversion plugging device for hydraulic engineering and using method thereof

Abstract

The invention relates to municipal engineering, and particularly relates to a riverway diversion plugging device for hydraulic engineering and a using method thereof. A base is arranged on a riverbed,a plurality of supporting seats are arranged on the base, a liftable dam body is mounted through the supporting seats, the dam body ascends and descends, adjustment is carried out according to the water level requirement, so that the water storage amount is controlled, the dam body is supported through a dam body supporting device after being lifted, a gap is formed between the riverbed and the lower end of the dam body, due to the action of the dam body, the water level rises, and the water flow pressure intensity of the lower portion of the dam body is increased, the water flow speed is increased, the good desilting effect can be achieved, the bottom of the dam body and the riverbed are not fixed, taking-out and maintenance are convenient, the dam comprises a supporting pipe, a fillingcore is arranged in the supporting pipe, the difference value between buoyancy and gravity can be controlled by controlling the weight of the filling core, then the stability of the dam body is controlled, a corrosion-resistant layer and a waterproof layer are arranged, the good waterproof and corrosion-resistant effects are achieved, and the service life is long.

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
