[0058] Such as figure 1 , figure 2 , image 3 , Figure 4 Shown in is a visual test device for simulating tunnel water inrush. The water source required by the model is supplied by high-pressure water pump 3; the model box 1 is a cuboid device made of tempered glass, and the joints between the glasses are sealed with glass glue. To achieve no water seepage and no water leakage; the box is filled with fluid-solid coupling similar material 7, which is used to simulate the anti-outburst rock mass of the tunnel; the upper cover of the box body can be disassembled from the main body, and it is sealed with the box body by a rubber gasket 14 and bolts 15 Fixed; the right side of the box is open without any obstruction.
[0059] The left side of the box is connected to the high-pressure water pump 3 through a water inlet pipe 4 with a diameter of 50 mm. A flow meter 5 is arranged between the water inlet pipe 4 and the box body. The water inlet pipe 4 is located in the center of th...
