Recyclable screw-in anchor rod-microorganism grouting reinforcement device and method

Abstract

A recyclable screw-in type anchor rod-microorganism grouting reinforcement device comprises a bacterial liquid tank, a water tank, a cementing liquid tank and a screw-in type anchor rod. Materials in the bacteria liquid tank, the water tank and the cementing liquid tank are input into the screw-in anchor rod through a grouting pump and a pipeline; the screw-in type anchor rod is hollow inside and provided with a slurry outlet hole in the outer wall; after the screw-in type anchor rod is screwed into the slope body, materials are injected into the slope body from the slurry outlet holes. According to the recyclable screw-in type anchor rod-microorganism grouting reinforcement device, green and environment-friendly materials are adopted, the reinforcement mode is changed, and it is guaranteed that the grouting reinforcement effect is reliable.

Description

technical field [0001] The invention relates to a grouting reinforcement device for shallow side slopes, in particular to a recyclable screw-in bolt-microorganism grouting reinforcement device and method. Background technique [0002] Since the beginning of the 21st century, the scope of human engineering activities has continued to expand, and resource development and demand have continued to expand. At the same time, the engineering geological and hydrogeological conditions gradually deteriorated. Geological disasters such as collapses, landslides, and debris flows caused by slope instability are increasing day by day. [0003] For some loose medium slopes such as granite residual soil and gravel soil with relatively slow dip angles, which generally do not cause large-scale landslide damage under the action of heavy rain, there will be relatively serious soil erosion and local shallow slump problems. At present, there is no systematic countermeasures for the reinforcemen...

AI Technical Summary

Problems solved by technology

[0004] 1) When anti-slide piles, retaining walls, prestressed anchor cables and other measures are used for reinforcement, due to the loose soil quality of such slopes, there will be problems such as poor reinforcement effect, unstable reinforcement performance and high energy consumption of reinforcement materials.

[0005] 2) When traditional grouting is used for reinforcement, the grouting materials used are cement, lime or chemical grouting materials. Such traditional grouting materials will make the soil alkaline and cause damage and pollution to the surrounding vegetation and groundwater.

[0006] 3) When using shallow anchor bolts for reinforcement, the force range of conventional anchor bolt reinforcement is small and the reinforcement effect is not suitable for this kind of situation; when using spray anchor support, a layer of concrete formed on the surface of the slope, a On the one hand, it affects the ecological environment, on the other hand, the large deformation of loose soil often leads to the deformation and damage of the concrete layer
