Abstract

The invention relates to a debris flow pile group protection structure and system based on an energy conversion enhancement mechanism. The debris flow pile group protection structure comprises a ground beam, a cantilever beam, a fixed pile and a rotating pile, the ground beam is installed on the ground, the cantilever beam is parallel to the ground beam, the fixed pile is perpendicular to the cantilever beam and the ground beam, and the two ends of the fixed pile are fixedly connected with the cantilever beam and the ground beam correspondingly; and the upper end of the rotating pile is rotationally connected with the cantilever beam, and the rotating pile is connected with the ground beam through an energy dissipation anchor cable structure. Compared with the prior art, on the basis that the advantages of an original pile group structure are reserved, dissipation of debris flow impact energy by the pile group structure is further improved, the energy of debris flow is further absorbed or converted through the pile group structure besides energy dissipation through internal interaction inside the debris flow, therefore the debris flow pile group protection structure is suitable for prevention and treatment of the debris flow with different water contents, and the protection effect is good.

Description

technical field

[0001] The invention relates to the field of disaster prevention and mitigation of geological disasters, in particular to a protection structure and system for debris flow pile groups based on an energy conversion enhancement mechanism. Background technique

[0002] Debris flow refers to landslides or torrents caused by heavy rain, snowstorm, earthquake or other natural disasters, and carries a large amount of solid debris such as sand and stones. This kind of natural disaster mostly occurs in narrow valleys and areas with steep terrain. It has the characteristics of suddenness, fast flow rate, short duration, large flow rate, large amount of solid matter, and strong destructive power. It often causes great property losses and casualties.

[0003] my country is a country with frequent debris flow disasters and extremely serious losses, especially in strong earthquake areas, strong earthquake disturbances, excessive and unreasonable post-earthquake reconstruct...
