Method for storing and getting water by blocking river on natural river course

Abstract

The invention discloses a method for storing and getting water by blocking a river on a natural river channel, which comprises the following steps: according to the width and the geographical conditions of the natural river channel, constructing a water-blocking rubber dam with rubber bags charged with air or filled with water; controlling the height of the dam body by adjusting the air charging amount and the water injection amount to achieve the functions of water storage, flood discharge and desilting and sand discharge; and simultaneously, mounting upstream and downstream water box culverts and gates outside a water intake and the rubber dam body so as to ensure that the dam body is unnecessary to be cut off during overhauling and maintenance. Because a matched flood discharge river channel is unnecessary to be excavated, the position of the dam is not limited by the geographical conditions for excavating the flood discharge river channel so that the damp has strong adaptability to the device positions and the environment. The method has the advantages of low manufacturing cost for the dam body, easy construction, short engineering construction cycle, low construction cost, low investment, and good application prospect.

Description

A method for blocking and storing water in a natural river course and taking water technical field The invention belongs to the technical field of water conservancy engineering, and in particular relates to a method for blocking water on a natural river for water storage and water intake. Background technique For water storage and water intake on natural rivers, at present, reinforced concrete irrigation and fixed dams are widely used at home and abroad, which has a long construction period, complicated process and large investment. The fixed dam is used to block the river to take water, the height of the dam body is fixed, and the height of the water storage level can no longer be adjusted freely through the height of the dam body. Instead, it is necessary to build a special flood discharge channel or set up a flood discharge gate on the dam. Adjust the height of the flood discharge channel entrance or the flood gate installed on the dam, control the storage water level, ...

AI Technical Summary

Problems solved by technology

At the same time, although the fixed dam has a sand discharge design, there are still problems such as cumbersome sand discharge operation, low efficiency, incomplete sand discharge, and partial sediment deposition.

Moreover, due to geographical constraints, some water intake stations that could have been built with fixed dams to store water had better locations, but because they did not have the conditions to excavate flood discharge channels, they had to choose another location. Construction brings many problems
