Construction method of high pressure spraying microbial bacteria liquid to deposit calcium carbonate to control landslide

Abstract

The invention relates to a construction method for high-pressure spraying microbial bacterial liquid to deposit calcium carbonate to treat landslides. The plan includes the following construction steps: cleaning the slope surface of a potential landslide body, and arranging an operation platform; Drilling to form a plurality of liquid injection holes; inserting a steel flower tube closed at the bottom into each liquid injection hole; injecting microbial bacterial liquid into each steel flower tube; elevating the steel flower tube according to the set speed until it is lifted to a soft sliding Stay at the surface for a set time and then continue to lift the steel flower tube; stop the microbial injection when the bottom elevation of the steel flower tube exceeds the weak sliding surface elevation by at least 1m; pull out each of the steel flower tubes, wait for the bottom of each injection hole. After the microbial deposition of calcium carbonate is completed, microbial bacterial liquid injection and soil filling are performed in each liquid injection hole again. The invention has the advantages of reducing the damage to the mountain and the ecological environment, and has the advantages of fast construction speed and low construction cost.

Description

technical field [0001] The invention relates to the technical field of disaster relief and emergency rescue, in particular to a construction method of high-pressure spraying microbial bacterial liquid to deposit calcium carbonate to treat landslides. Background technique [0002] Landslides are one of the most common geological hazards. my country has a vast territory and there are a large number of mountainous slopes, and the area affected by landslides is also considerable. Most houses in mountainous areas are built on mountains, so landslides mostly occur in front of and behind houses, seriously threatening the people and property of people in mountainous areas. Safety has led to the severe emergency response and prevention tasks of geological disasters for many years. Every rainy season, the emergency response to landslides makes the relief workers overwhelmed and caught off guard. At present, the commonly used landslide disposal methods mainly include landslide removal...

Problems solved by technology

However, it did not strengthen the most critical weak sliding surface in the landslide. At the same time, the two most critical factors for the deterioration of the landslide: the groundwater infiltrated from the rear edge of the landslide and the surface water and rainwater infiltrated from the slope surface were not isolated. Therefore, the reinforcement effect is not good
