Method for preventing debris flow disaster and reusing debris flow products

Abstract

The invention relates to a method for preventing debris flow disaster and reusing debris flow products. The problems that the debris flow blocking dam body has bad flood relief effect and damage to the dam body is easily caused in the prior art, and the problem that prevention measures on impact on the dam body by large stones do not exist are solved. The method is characterized by comprising the following steps: building a stone blocking pile at the gentle slope position of a mountainside and building a water diversion trench below the stone blocking pile; building a mud blocking damp at the position at the foot of a mountain, building a water blocking damp below the mud blocking damp at the foot of the mountain, and building a plurality of flood discharging trenches on the upper part of the mud blocking damp; and reusing the debris flow products. By the method, impact of the debris flow on the mud blocking damp can be reduced and the flowing direction of the flood in the debris flow is guided, so that the degree and the influence range of the debris flow disaster are effectively reduced; and mud and water which are generated by the debris flow can be separated and the debris flow products can be reused.

Description

technical field [0001] The invention belongs to the technical field of prevention and control of natural disasters, and in particular relates to a method for preventing debris flow disasters and reusing mud-rock flow products that can reduce the degree and scope of debris flow disasters, separate mud and water generated by debris flow, and realize the reuse of debris flow products . Background technique [0002] Debris flow is a torrent formed by torrential rains and floods that will contain sand and soft soil mountains after saturation and dilution; a typical debris flow is composed of viscous mud rich in silt and clay in suspension of coarse solid debris. Debris flows often have the characteristics of sudden eruption, ferociousness, and rapidity, and have the dual effects of collapse, landslide and flood damage, so the degree of damage is more serious than single collapse, landslide and flood, and the scope is wider. Mud-rock flow has great harm to residential areas, tran...

AI Technical Summary

Problems solved by technology

The debris flow retaining dam in the first two methods cannot produce the effect of flood discharge when encountering a large debris flow disaster, and the dam is prone to damage

The above methods also do not mention the preventive measures against the larger rocks mixed in the debris flow, which cannot reduce the impact of the larger rocks in the debris flow on the dam body

At the same time, none of the existing technologies mentioned the concept of mud and flood reuse, nor did they have specific descriptions and hints on the separation and treatment methods of flood and mud.
