Abstract

The invention relates to the technical field of fish way engineering in the water and electricity industry, and particularly relates to a natural vertical seam type fish way structure with the adjustable flow speed. The natural vertical seam type fish way structure comprises a fish way bottom plate, wherein fish way side walls are vertically arranged on the two sides of the top of the fish way bottom plate, the fish way bottom plate and the fish way side walls are of an integrally-formed structure, and a plurality of speed adjusting units are arranged between the two fish way side walls at equal intervals. According to the natural vertical seam type fish way structure, a large number of natural building materials such as sandy gravel are used, the flow speed of the fish way water flow is adjusted, the characteristics of a natural river channel are simulated to the maximum extent, a good fish passing environment and the most suitable water flow condition are created for fish passing objects, the advantages of being high in fish passing efficiency and environmentally friendly are achieved, and the defects in the prior art can be well overcome.

Description

technical field

[0001] The invention relates to the field of fishway engineering in the hydropower industry, in particular to a natural vertical seam fishway structure with adjustable flow velocity and a construction method thereof. Background technique

[0002] Domestic research work on fish passing facilities is more than 300 years later than that of foreign countries, and there is a lack of technical information on fish passing facilities. The earliest reference to the fishway concept in China was the Qililong Hydropower Station on the Fuchun River; in 1966, the Longgang Gate in Dafeng County built the first fishway in my country; during the construction of the Gezhouba Water Conservancy Project, there was great controversy over the construction of fish passage facilities, and the final choice was The problem of protecting rare fishes such as Chinese sturgeon in the Yangtze River is solved by artificial breeding and release. In the following 20 or 30 years, the river barr...
