Method and device for achieving unidirectional flow of beheaded river through tide

Abstract

The invention discloses a method and device for achieving unidirectional flow of a beheaded river through tide. A cutoff wall is arranged in the center of the beheaded river with the river width beingB. The initial end of the cutoff wall is B / 2 away from the beheaded river head, and the terminal end of the cutoff wall is located at the intersection of the beheaded river and a main tidal waterway.Check gats are arranged between the two sides of the terminal end of the cutoff wall and the beheaded river bank correspondingly, one of the check gates is a water inlet check gate which is opened during tide rising for controlling water flow of the main tidal waterway to flow into the beheaded river unidirectionally, and the other check gate is a water outlet check gate which is opened during tide falling for controlling water flow of the beheaded river to flow into the main tidal waterway unidirectionally. Through the cutoff wall and the two check gates, tide water power can be used, rising-falling repeated flow of the beheaded river is changed into unidirectional circular flow, refreshed water amount is proportional to the tidal range and the beheaded river water area, the water flow effect is good, the refreshed water amount is high, the water level of the beheaded water is controllable, the method and device are easy and convenient to implement, project investment is reduced, theconstruction period is short, the operation and maintenance is low, and the method and device have the application and popularization prospects.

Description

technical field [0001] The invention relates to a device for improving the water environment of a river course, in particular to a device for realizing the one-way flow of Duantou River by using tides, and belongs to the field of water conservancy. Background technique [0002] The task of urban and rural river water environment governance is very heavy, and connecting Duantou River to achieve smooth flow of water is one of the extremely important governance measures. At present, the methods for connecting the Duantou River to running water mainly include the following: one is to connect the Duantou River with other Duantou Rivers (or other main rivers); the other is to connect the Duantou River with the Lay pipelines and build pumping stations between other Duotou Rivers (or other main rivers) to achieve connectivity (see literature: Cheng Ying, Zhou Yulin, Application and Analysis of Pipe Jacking Technology in Duantoubang Opening Project, [J] Water Conservancy Science and ...
