The invention discloses a grouting slurry diffusion multi-factor testing system of a fractured rock mass. The testing system is composed of a plurality of subsystems: a fixing system, a fracture imitating system, a parameter regulation system, a monitoring system, a control system and a grouting system. When a test is carried out, the fracture imitating system is mounted through the fixing system,the parameter regulation system and the monitoring system are mounted and the control system is connected; after each system is debugged, the grouting system is connected. An imitated fracture is made of a PVC (Polyvinyl Chloride) transparent plate and adjustment of spreading width of an imitated rock mass fracture, roughness, a fracture inclined angle, fracture height and a water content condition can be realized through utilizing the parameter regulation system, so that a slurry diffusion rule under a plurality of factors is analyzed. All components have a coordinated effect to realize testing researches of influencing slurry diffusion by multi-fracture parameters. The grouting slurry diffusion testing system is innovatively improved, and the accuracy, integrity, operability and low cost of a test are sufficiently considered; the grouting slurry diffusion multi-factor testing system has great significance on researches of a grouting theory, grouting engineering and a grouting technology.
Description
technical field [0001] The invention relates to a laboratory test system for grouting engineering, in particular to a multi-factor test system for grouting grout diffusion in cracked rock mass. Background technique [0002] As a highly practical engineering technology, grouting is widely used in anti-seepage and water blocking projects such as mining engineering and tunnel engineering, and its technical means are relatively mature. However, the problems encountered in the current engineering practice cannot be well explained by theory, that is to say, the current theoretical research on grouting cannot be adapted to the application of engineering technology. Therefore, it is necessary to deeply analyze and expand the grouting theory. However, the complexity of the geological environment of rock and soil and the concealment of the grouting engineering have brought great difficulties to the research of grouting diffusion and grouting reinforcement. The indoor model test has be...
