A control method for grouting reinforcement grout diffusion

Abstract

The invention discloses a control method for grouting reinforcement grout diffusion, which comprises 1) strengthening the basic unit by grouting, completing the grouting reinforcement action in the first stage, and realizing the purpose of grouting reinforcement in surrounding rocks; The judging unit monitors and judges the whole process of the grouting process, and if it finds the needling-type diffusion of the reinforcement grout, it transmits the response command to the grout column spherical diffusion control unit; 3) the grout column spherical diffusion control unit receives the grout and After the judgment conclusion and action command of the acupuncture-type diffusion, adjust the grout diffusion mode to the column-type diffusion mode, and then continue grouting; 4) After the first stage of grouting is completed, use the grouting reinforcement effect evaluation unit to The grouting reinforcement effect is evaluated, and the parameters of the grouting reinforcement basic unit, the grout needle-punched diffusion judgment unit and the grout column spherical diffusion control unit are adjusted according to the evaluation results, and the second-stage grouting is performed using the adjusted parameters reinforcement.

Description

technical field [0001] The present invention relates to a grouting reinforcement method and process, in particular to a grouting reinforcement method and process for cylindrical surface grouting of mine roadways, hydropower chambers, tunnels, and subway surrounding rocks under the condition of fractured surrounding rocks with developed cracks system. Background technique [0002] With the rapid development of my country's infrastructure construction, more and more projects such as mine chambers, roadways, water conservancy and hydropower, railways, highways, subway tunnels and other projects are facing harsh geological conditions. Especially in the case of well-developed cracks in the surrounding rock, the surrounding rock has poor integrity and insufficient bearing capacity, which can easily cause engineering accidents such as landslides, roof falls, and slabs, resulting in frequent casualties, which hinder the smooth construction of the project and the protection of mine r...

AI Technical Summary

Problems solved by technology

[0006] The problem addressed by the present invention is that the grout needle-punched diffusion existing in the current broken surrounding rock grouting reinforcement project leads to unreasonable distribution of grout and low material utilization rate. The present invention improves The ability of manpower to control the spread of grout can effectively control the spread range and mode of the grout, try to avoid the needle-like spread of the grout in the grouting reinforcement of the broken surrounding rock, so that the grout can be more concentrated in the predetermined reinforced rock mass range, Reduce material waste and obtain better surrounding rock control effect at a lower cost
