System and method for inducing and controlling landslide with compressed air

Abstract

The invention discloses a system and a method for inducing and controlling landslide with compressed air. The system comprises a compressed air acting face, a set landslide body, a compressed air injection pipe, a compressed air distribution pipe, a pressure stabilization chamber, a pressure gage and an air compressor; the compressed air injection pipe extends to the compressed air acting face from the surface of the set landslide body, and is connected with the pressure stabilization chamber through the compressed air distribution pipe; and the pressure stabilization chamber is connected withthe air compressor through a pump chamber connection pipe. The landslide can be controlled manually, existing buildings below the landslide body are protected, or the generation of barrier lakes is avoided; the defects that mountain water resources and other materials are limited in the acquiring way, and are inconvenient to carry are overcome; and the effect of eliminating landslide hazard can be achieved only by using a simple device system, the construction amount is small, the construction and implementation costs are greatly reduced, environment pollution is avoided, the operability is high, and the application range is wider.

Description

technical field [0001] The invention relates to the field of engineering construction, in particular to a system and method for inducing and controlling landslides by using compressed air. Background technique [0002] Our country is a mountainous country. When building transportation facilities in mountainous areas, we often face the threat of landslides, such as figure 1 Among them, there is a landslide-prone body 101 above the proposed highway 102, which poses a serious threat to the proposed highway 102. In the prior art, the retaining wall 103 is usually constructed between the landslide-prone body 101 and the proposed road 102, or structural measures such as anchor rods 104 are set in the landslide-prone body 101 to improve the stability of the landslide-prone body and ensure the road 102 below. security. However, the construction cost of these methods is high, the construction difficulty is relatively large, and the durability is limited, so it cannot fundamentally ...

AI Technical Summary

Problems solved by technology

However, the construction cost of these methods is high, the construction difficulty is relatively large, and the durability is limited, so it cannot fundamentally prevent and control landslide disasters, and cannot completely eliminate the potential safety hazards caused by landslide disasters.

[0003] Moreover, the lithology of the rocks on the landslide-prone mountains is poor, the rock strata are broken, loose, strongly weathered, the soil is soft, and the shear strength is low. Therefore, it is difficult to use local materials for construction on landslide-prone mountains, and the water resources on the mountains are not easy Obtaining, the required water and other materials need to be transported from downhill to the required location, which greatly increases the difficulty and cost of construction
