Fractured rock mass intelligent grouting measurement and control system and implementation method thereof

Abstract

The invention discloses a fractured rock mass intelligent grouting measurement and control system and an implementation method thereof. The system comprises microseismic detectors, a data substation,an underground monitoring host, a server, a grouting pump, an intelligent control valve and a grouting control end. According to the implementation method comprises, real-time signal sources are monitored in slurry diffusion through utilization of a microseismic monitoring technology; positioning is carried out timely; a practical effective diffusion range of slurry is obtained after verificationis carried out; the practical effective diffusion range is compared with a required grouting diffusion diameter to obtain an evaluation parameter; a difference value between the evaluation parameter and a threshold set by a server terminal is computed; the difference value is fed back to the grouting control end based on a set diffusion computing return program; grouting parameters are dynamicallyadjusted; accurate control over a grouting system is realized based on effect of the intelligent control valve; and intelligent pressure increased and reduced grouting or flow increased and reduced grouting is carried out or grouting is stopped in real time. According to the system and the method, the grouting parameters are dynamically and intelligently adjusted, the effective diffusion range ofthe slurry is accurately realized, slurry material waste is reduced, cost is reduced, and safety and high efficiency of grouting engineering are ensured.

Description

technical field [0001] The invention belongs to the technical field of rock mass grouting, and relates to a measurement and control system and implementation method for intelligently controlling and dynamically adjusting grouting parameters based on the actual conditions of grouting diffusion in a grouting project, in particular to an intelligent grouting measurement and control for cracked rock mass systems and implementation methods. Background technique [0002] In various civil engineering constructions, it is often encountered in construction difficult layers such as broken zones, loose zones, weak bottom layers, water inrush layers, etc., and grouting technology is used as a solution The methods for water inrush and instability damage problems have been widely used.

Problems solved by technology

However, the proportion of ultra-long and wide tunnels and subsea tunnels in my country's construction is increasing, which poses more severe challenges to grouting technology and theory.

[0003] Due to the complexity and concealment of engineering rock mass, researchers have conducted extensive research on grouting theory and grouting effect analysis, but the relationship between theoretical research and engineering application is still in its infancy, especially for on-site grouting. The implementation process of the system currently lacks the accurate identification of the grout diffusion range in the actual grouting project, and the lack of dynamic adjustment of the grouting parameters based on the actual diffusion problem
