Description

Technical Field

[0001] The invention relates to the technical field of dam protection, in particular to an anti-scouring dam protection device for water conservancy projects. Background Art

[0002] A dam is a wall or long pile of materials such as earth, stone or concrete, usually built along the edge of a river, lake or coastline. Its main function is to protect the surrounding land from flooding and seawater intrusion, but it is also used to regulate water levels, prevent soil erosion, and provide hydroelectric power.

[0003] Most modern dams are built with high-strength concrete, but when the water flow rate is high, the dam may still be damaged. Therefore, in order to increase the service life of the dam, anti-scouring dam protection devices are generally built to improve the protection effect of the dam and reduce the resistance of large water. However, the existing anti-scouring structures generally protect the dam by resisting the impact force of water flow. This protection method converts the impact force acting on the dam to the anti-scouring structure, thus achieving the protection purpose. However, the anti-scouring structure will also be worn or even damaged due to long-term impact of water flow, and the long-term use effect is not good. For this reason, an anti-scouring dam protection device for water conservancy projects is proposed for improvement. Summary of the invention
