Embodiment Construction

[0028] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0029] Such as Figure 1-Figure 4 , a simulated crack grouting model test platform with a variable inclination angle, including a simulated crack 1, a pressurized water tank 2 and a liftable support 3. The simulated crack is composed of two tempered glass plates parallel to each other, 3mm apart, and 1000×560mm in size. A 20mm grouting hole 4 is reserved at the center of the lower glass plate at a distance of 350mm from one short side. During the test, the simulated crack 1 can be reassembled as needed, the width of the simulated crack 1 can be adjusted, and porous media can be filled in the simulated crack 1 to simulate seepage grouting under different media conditions. The stabilized pressure water tank 2 is hinged with the short side of the simulated crack 1 that is closer to the grouting hole 4. There is a water inlet hole on the outside of the sta...

Abstract

The invention discloses a variable-dip-angle simulated fracture grouting model test platform. The variable-dip-angle simulated fracture grouting model test platform comprises a simulated fracture, a pressure stabilizing water tank and a liftable supporting base, wherein the simulated fracture comprises two glass panels, a grouting hole is formed in the lower side glass panel, and the space between the two glass panels is filled with porous media, the pressure stabilizing water tank is hinged to the upper side glass panel of the simulated fracture, the liftable supporting base is fixed to the lower end of the lower side glass panel of the simulated fracture and comprises a connecting disk, a lifting rod and a base, the connecting disk is fixed to the lower side glass panel of the simulated fracture, the lifting rod is fixed to the lower end of the connecting disk, and the other end of the lifting rod is fixed to the base. The simulated fracture can be assembled again as required, the width of the simulated fracture is adjusted, the simulated fracture can be filled with porous media, and permeation grouting under different medium conditions is simulated. The test platform is a model test device capable of being used for researching influences of fracture parameters, grout parameters and other parameters on grout diffusion in the fracture flowing water grouting simulating process.

Description

technical field [0001] The invention relates to a simulated crack grouting model test platform with variable inclination angle. Background technique [0002] Water inrush disaster is a kind of severe geological disaster often encountered in underground engineering. The main treatment method for water inrush disasters is grouting, especially the dynamic water grouting technology is mostly at the stage of empirical development, without mature theories and technologies, and lack of scientific guidance, resulting in perennial water inrush problems in most deep mines and tunnels. While bringing safety threats to the project, it also burdened the enterprise with a heavy economic burden, wasted national resources, and caused certain damage to the ecological environment. [0003] The basic form of water conduction channel for water inrush in most underground engineering is simulated fracture (fault can be regarded as a special form of simulated fracture). Therefore, the basis of th...
