An assembled fishway and construction method

Abstract

The invention provides an assembled fishway and a construction method, mainly comprising multi-section fish pond structural unit components and fish pond lower supporting structural columns supporting the fish pond structural unit components; the cross section of the fish pond structural unit components is consistent with the fishway, and the fish pond structural unit components It includes the bottom plate and the fishway groove walls on both sides; the fish pond structural unit components are prefabricated components in the factory; the integral fishway is formed by splicing several fish pond structural unit components; a water-stop structure is set between adjacent fish pond structural unit components. The invention improves the construction efficiency and construction quality of the fishway, reduces construction interference with the main structure, accelerates construction progress, reduces construction safety risks, and saves construction investment.

Description

technical field [0001] The invention relates to an assembled fishway and a construction method, which are applicable to the technical field of design and construction of auxiliary buildings of water conservancy and hydropower projects. Background technique [0002] Large and medium-sized water conservancy and hydropower projects constructed in alpine and valley areas often build artificial water tanks as fish migration channels, which are called fishways, in order to reduce the impact on fish migration habits after dam construction and operation cut off rivers. Limited by technical indicators such as fishway water depth and flow velocity, a gentle and stable slope must be maintained in the fishway. Therefore, the length of the fishway is often very long. For example, a high dam of about 100m requires a fishway length of about 3km to 4km. On the one hand, the construction of Changyu Road is limited by the terrain and geological conditions, making it difficult to arrange const...

AI Technical Summary

Problems solved by technology

[0004] (1) The fishway is long along the line, the cross-section is small, and the structure mostly involves high-altitude operations, the construction efficiency is low, the construction safety risk is high, and a lot of manpower and material resources are required, and the cost is high

[0005] (2) The layout of the fishway requires a large amount of construction sites along the line for stacking steel bars, formwork and other materials, as well as operating and parking construction equipment. However, the site in the alpine and canyon areas is limited and the layout is difficult, which has a great impact on the surrounding environment

[0006] (3) There are many construction procedures of the fishway and the operation time is long. On the one hand, its own efficiency is low, which affects the construction progress; At the same time, it also increases the safety risk caused by cross-operation
