Device capable of realizing water delivery through soft covered channel changed from open channel

Abstract

The invention discloses a device capable of realizing water delivery through a soft covered channel changed from an open channel. The device comprises water delivery pipelines and water delivery power units. The water delivery pipelines are located in the open channel. The water delivery pipelines are made of soft materials. Each water delivery pipeline is provided with a pipeline inlet and a pipeline outlet. The water delivery power units are arranged on a dam body. Each water delivery power unit is provided with a water inlet end and a water outlet end, the water inlet end communicates with a water source, and the water outlet end is connected with the pipeline inlet of the corresponding water delivery pipeline. By adopting the device, the water delivery speed can be increased; pollution and evaporation of water are reduced in the water delivery process; moreover, an existing open channel structure does not need to be changed, and the water delivery device is easy to construct and convenient to maintain and manage.

Description

technical field [0001] The invention relates to the technical field of water delivery, in particular to a water delivery device for converting an open channel into a soft underground channel. Background technique [0002] An open channel is a channel with a free surface (the points on the surface are affected by atmospheric pressure) water flow. According to its formation, it can be divided into natural open channels and artificial open channels. The former is like a natural river; the latter is like an artificial water channel, canal, etc. . [0003] In our country, in the existing water dispatching projects, open channel water delivery is mostly used. For example, the largest South-to-North Water Diversion Project in the world today adopts the open channel water delivery method of full-line self-flowing. The water depth in the channel is 3.8-8.0m. North gradually decreases. This method of using water level difference in the open channel has the advantages of low cost, sm...

Problems solved by technology

This method of using water level difference in the open channel has the advantages of low cost, small buried depth, and linear collection of water, but it is easy to be polluted, and the water will cause evaporation and seepage during the transportation process. If the underground channel is used Water delivery can avoid the occurrence of these situations. The use of underdrain water delivery, the water is not easy to evaporate, and in the process of water delivery, it has the advantage of not being easily polluted by the surrounding environment or man-made. However, the underdrain water delivery method adopted in the prior art , mostly use water pipelines made of hard materials, buried deep underground for water delivery, which has the disadvantages of high cost and unsuitable maintenance.
