Post collapse ecological control method based on microorganism reinforcement technology

Abstract

The invention relates to a post collapse ecological control method based on a microorganism reinforcement technology. The scheme comprises the following construction steps of: cleaning at least one operation platform on a post collapse erosion body; drilling the surface of the post collapse erosion body to form a plurality of erosion body anchoring holes; inserting an anchoring pile into each erosion body anchoring hole, and performing microorganism grouting on each erosion body anchoring hole for multiple times to form a calcium carbonate anchoring body; laying a three-dimensional net on the surface of the post collapse erosion body and connecting the three-dimensional net with the tail end of each anchoring pile; spraying an anti-erosion material onto the three-dimensional net until the three-dimensional net is completely covered by the anti-erosion material; and spraying a layer of microorganism grouting slurry onto the surface of the anti-erosion material again to form a calcium carbonate thin layer. The method has the advantages of ecological environmental protection, no pollution, short construction period, convenience in construction, high strength and high anti-erosion capability.

Description

technical field [0001] The invention relates to the technical field of ecological prevention and control, in particular to a method for ecological prevention and control of collapsing hillocks based on microbial reinforcement technology. Background technique [0002] Collapse is defined as "an erosion phenomenon in which the hillside soil is damaged and collapsed and scoured under the action of water and gravity". During the weathering process of granite with well-developed joints, various joint surfaces will be produced under the action of gravity, weathering and landform evolution, and various structural planes will cut the weathering crust. Under this condition, the structural surface will continue to open, from closed to slightly open-wide open, which increases the instability of potential collapsed bodies and creates the geological soil foundation of collapsed hills; Continuous downcutting destroys the original balanced in-situ stress, causing the release of in-situ st...

Problems solved by technology

In the past, some scholars tried to strengthen the rock and soil mass by generating calcium carbonate through chemical reaction, but found that this method could not generate massive cemented bodies, so that the reinforcement effect was not significant enough, that is, the non-cemented calcium salt did not Can not improve the mechanical properties of rock and soil
