Landslide inflatable drainage treatment method

Abstract

The invention discloses a landslide inflatable drainage treatment method which comprises the flowing steps of: firstly, arranging boreholes, inside which air pipes are inserted, wherein the air pipes inserted in the boreholes are divided into two segments, namely, a closed borehole wall segment and an open borehole wall segment; connecting the air pipes and cross joint valves with an air compressor and the air pipes inserted in the boreholes; then pressing air into all the boreholes and inflating potential landslide mass, and squeezing out groundwater in the potential landslide mass by air pressure so as to achieve air-water displacement. When the pressed-in air bursts from the earth surface, the pressing of the air into the potential landslide mass is stopped. After a 1 to 2-day interval,inflation is conducted again for 3 to 5 times to achieve the aim of improving the stability of the potential landslide mass. By applying the invention, the landslide control project cost is low, thecontrol project implementation process is simple and convenient, and the governance process does not involve earth and stone excavation works, thus quickly producing reinforcing effects, with especially obvious effects in landslide rescue disposal.

Description

A method for treating landslides with aeration and drainage technical field The invention relates to a method for treating landslides, in particular to a method for treating landslides with aeration and drainage. Background technique Landslides are common geological disasters, especially in the process of engineering construction in hilly areas, landslide disasters often cause significant losses to engineering construction. The vast majority of landslides are closely related to rainfall, because rainfall causes the groundwater level of the slope to rise, leading to the occurrence of landslides. Most landslides are characterized by sliding in the rainy season and relatively stable in the dry season. Especially for cohesive soil slopes containing gravel, they are mostly residual slope accumulations, ancient collapses or ancient landslide accumulations, and their stability is closely related to groundwater level changes. The rise of the slope groundwater level is a cumulati...

AI Technical Summary

Problems solved by technology

The main problems existing in landslide drainage measures at present are: (1) drainage measures have high requirements on the drainage environment of the slope body, and many slopes often lack favorable landform environment, which makes it difficult to guarantee the effectiveness of drainage measures; (2) so far there is no active Drainage technical measures
