Ecological control method of collapsed hillock based on microbial reinforcement technology

Abstract

The invention relates to a method for ecological prevention and control of collapsed hillocks based on microbial reinforcement technology. The scheme includes the following construction steps: cleaning out at least one operating platform on the collapsed hillock eroded body; drilling holes on the surface of the collapsed hillock erosion body to form multiple erosions body anchoring holes; insert anchoring piles in each of the erosive body anchoring holes, and perform multiple microbial grouting on each of the erosive body anchoring holes to form calcium carbonate anchors; lay three-dimensional nets on the eroded ridges On the surface of the body and connected with the end of each anchoring pile; spray the anti-erosion material on the three-dimensional net until the three-dimensional net is completely covered with the anti-erosion material; spray a layer of microbial grouting slurry on the surface of the anti-erosion material again to form a layer The calcium carbonate thin layer has the advantages of ecological environmental protection, no pollution, short construction period, convenient construction, high strength and strong corrosion resistance.

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 collapsed hillocks based on microbial reinforcement technology. Background technique [0002] Collapse is defined as "the erosion phenomenon in which the soil mass on the slope is damaged by the action of water and gravity". During the weathering process of granite with developed joints, various joint surfaces will be produced under the action of gravity, weathering and landform evolution, and various structural surfaces will cut the weathering crust, under the effect of gravity and weathering forces (mainly including sunlight, climate, rain) The structural plane will continue to open, from closed to slightly open to wide open, which increases the instability of the potential collapse body and produces the geological soil foundation of the collapsed ridge; The continuous downward cutting will destroy the...

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
