A dam explosion-proof and anti-icing device and its construction method

Abstract

The application relates to a dam explosion-proof and anti-icing device and its construction method. The dam explosion-proof device is a four-layer composite structure, the first layer is an arc-shaped double-layer shell structure, and the second layer is a double-layer shell structure, the arc-shaped buffer energy-absorbing layer is set, the third layer is a cavity structure, and the fourth layer is a metal sandwich panel structure; the anti-icing device is a waterproof electric heating plate, which makes the water surface of the dam The water temperature is above 0°C to prevent the water surface from freezing. The fixed installation of explosion-proof and anti-icing devices is realized by embedded bolts, and the impact energy of the explosion is buffered by the above-mentioned four-layer structure arrangement, so that the impact energy after the explosive contacts the first layer of explosion is buffered and consumed layer by layer, ensuring the safety of the dam structure.

Description

Technical field: [0001] The application relates to the field of safety protection of hydraulic engineering buildings, in particular to an explosion-proof and anti-icing device for a hydraulic engineering dam and a construction method thereof. Background technique: [0002] Reservoir dams are set up to play flood control, power generation, irrigation and other functions. The safety of reservoir dams has an extremely important impact on the production and life of downstream people. If accidents such as dam failure occur, it may bring huge losses of life and property to downstream people. . Most of the current research on dam safety is limited to the study of the dam structure itself, ignoring the occurrence of abnormal situations such as terrorist attacks on the dam. However, many attacks on the dam in the last century have caused serious damage. Losses, dam explosion protection has gradually entered the field of vision of engineers and has been valued by the industry. [00...

AI Technical Summary

Problems solved by technology

However, there are very few engineering projects where the above research is applied to non-military fields, especially less research on riot resistance in water conservancy projects

[0004] In addition, in winter, the freezing of the water surface of the reservoir will cause damage to the dam surface and generate huge stress at the same time, which will damage the stability and safety of the dam. Therefore, the attention to the anti-icing of the dam, especially the anti-icing of the dam in northern my country is also increasing. However, the existing anti-icing technology is not effective, and there is no technology that considers anti-icing and explosion protection of dams
