Along with the fast development of China's infrastructure construction, road and rail tunnel, coal mine roadway, subway, water power chamber etc. are built more and more extensive. But along with the minimizing of superficial part resource is even exhausted, the mining degree of depth is more and more darker; At present increasing tunnel construction is among high mountain; Increasing underground engineering is in the severe geological environment such as large buried depth, soft rock, fault tectonic, causes Rock Slide Stability control difficulty to increase severely, and engineering project disaster takes place frequently.
Grouting and reinforcing is to improve rock stability, ensures the important technique measure of engineering safety; Grouting for water blocking is the major technique of processing at present prominent water burst problem in Geotechnical Engineering. But, because current slurry injection technique develops still imperfection, cause slip casting effect to can not get ensureing, distinct issues are the most: owing to there being the perforation crack that cannot directly observe in a large number in Rock And Soil, in slip casting process, how slurries spread, are diffused into the information such as what scope and cannot obtain, and cause the formulation of slip casting strategy very passive. During such as slip casting in the serious country rock of cranny development, often run into slurries pressure and remain on from start to end very low level always, slurries are only along the situation of advantage passage diffusion, even sometimes slurries only along a Directional Extension to injected hole beyond 10m ~ 20m and other direction wall-rock crack of injected hole periphery without any the situation of slurries filling. With this understanding, although grouting amount is very large, but very low to the integral-filled rate of wall-rock crack, cannot in country rock, form continuous filling reinforcing area, can not reach expection consolidation effect, but also waste material.
Therefore in, slip casting process, the monitoring of slurries dispersal pattern, diffusion parameter has important value for the research of grouting and reinforcing mechanism, technical development, scheme optimization. But still there is no at present the three-dimensional diffusion information that monitors slurries that corresponding equipment and technology can be effective, quantitative, real-time. Therefore, urgently developing at present a kind of monitoring system and method addresses the above problem.
