Problems solved by technology
[0006] To sum up, in the prior art, the experimental devices for rock mass fissure seepage and slurry flow simulation lack consideration of complex non-smoothness such as the heterogeneity of the hydraulic opening of the fracture surface, the undulating roughness characteristics of the fracture surface, and the occlusal state of local protrusions. Under the condition of plane cracks, the transparent and visualized quantitative observation of the parameters of the grouting process by some existing devices is still not perfect

Description
technical field [0001] The invention relates to the field of physical model tests of dynamic water grouting in rock mass fissures. More specifically, the invention relates to an experimental device and a pressure monitoring system for simulating the grouting process of rock mass fissures. Background technique [0002] There are discontinuities / cracks in natural rock mass, and the existence of these discontinuities provides channels for the migration of water or other harmful substances in the rock mass. It is very difficult to treat inrush water grouting in rock mass engineering, and there is no mature technology and theory for fissure water grouting technology. Due to the lack of scientific guidance, most deep-buried mines and tunnels have perennial water inrush problems. In order to solve the problem of water inrush control in water-bearing structures in rock mass engineering, it is necessary to study the seepage of fissure water and the law of grout diffusion in the proc...
