A construction method of an anti-collision device for a water conservancy project dam wave wall

Abstract

The invention provides a construction method for the anti-collision device of the anti-wave wall of a water conservancy project dam. By setting the second-stage concrete at the bottom of the anti-wave wall and fixing it with horizontal pre-embedded steel bars, it can effectively prevent the damage of the main body structure of the anti-wave wall ; The second-phase concrete pouring uses steel formwork, which will not be dismantled after the maintenance is completed, forming a steel-concrete structure, which improves the overall mechanical performance. Detachable damping plates are installed on the outside of the wave wall and the second-phase concrete surface to achieve flexible protection , improve the anti-collision effect, the detachable structure is easy to replace and install, and can save engineering cost.

Description

technical field [0001] The invention relates to the field of hydraulic engineering, in particular to a construction method for an anti-collision device of a dam wave wall of a hydraulic engineering dam. Background technique [0002] Water conservancy projects are projects that benefit the people by making full use of water resources, promoting water conservancy, and eliminating water damage. With the continuous improvement of my country's scientific and technological level, water conservancy projects have made major breakthroughs in both theory and practice, and have successively built Xiaolangdi and the Three Gorges, which have attracted worldwide attention. Through water conservancy projects, the reasonable matching of water resources has been effectively realized, which not only fully utilizes water energy resources, but also reduces flood damage. [0003] A dam is a typical water conservancy project. It is often built in the main stream of a river to re-match water resour...

AI Technical Summary

Problems solved by technology

[0004] According to different dam bodies, most of the anti-wave walls are built on the top of the dam body, which are mainly used for anti-wind and wave structures during flood periods. The thickness of anti-wave wall structures is often not large, but the loads they bear are mostly dynamic loads, especially during floods. There may be floating objects such as large trees in the upstream, which are easy to damage the structure of the dam wave wall, and then affect the storage function of the dam

[0005] The current reinforcement measures are mostly realized by increasing the ratio of steel bars or concrete strength, which cannot achieve flexible protection and cannot be replaced. Therefore, the protection effect is limited, and replacement is inconvenient, and the actual maintenance cost after damage occurs is higher.
