Its main purpose is to meet the needs of power generation, irrigation, urban industry and residential water use. A water diversion tunnel can be pressurized or non-pressurized. A pressurized water diversion tunnel usually needs to withstand huge internal water pressure, including potential water hammer pressure, which will cause the tunnel wall to rupture under pressure, resulting in water seepage and accumulation in the tunnel. Over time, the tunnel itself will deform and crack over a large area. Therefore, their tunnel walls often need to be firmly lined, sometimes even steel plate lining, to reinforce the tunnel walls. For this purpose, application number: 202420365074.4 discloses a water-rich crushed surrounding rock reinforcement device for a water diversion tunnel, including a support plate, the upper surface of the support plate The surface is fixedly connected with an arc plate, and a slide groove is provided on the side of the support plate, and the inner wall of the slide groove is slidably connected with a slider, and a ball bearing is rotatably connected to one side of the slider, and the other side of the slider is fixedly connected to the connecting plate, and the upper surface of the connecting plate is fixedly connected to the circular arc plate; the device reinforces the surrounding rock in the tunnel once through the provided support plate and the arc plate. When the arc plate in contact with the surrounding rock is damaged and cracked, a control rod that can be raised and lowered on the surface of the arc plate is used to drive the top plate to move through the limit plate, and a silicone plate is provided between the top plate and the arc plate, so that the top plate and the silicone plate perform secondary reinforcement protection on the arc plate and the surrounding rock to prevent the surrounding rock from being damaged and collapsed, thereby enabling the reinforcement device to have the effect of reinforcing the water-rich damaged surrounding rock of the water diversion tunnel, thereby increasing the stability in the water diversion tunnel;

[0003] The water-rich and broken surrounding rock reinforcement device for a water diversion tunnel disclosed in the above patent performs a primary reinforcement of the surrounding rock in the tunnel through a support plate and an arc plate, and performs a secondary reinforcement and protection of the arc plate and the surrounding rock in conjunction with a top plate and a silicone plate, thereby effectively reinforcing the water-rich and damaged surrounding rock of the water diversion tunnel. However, it still has the following deficiencies during use: the height of the support plate and the width of the arc plate are fixed, so that it can only reinforce the water-rich and broken surrounding rock of the water diversion tunnel of the same size. When there is a height or width deviation between the water-rich and broken surrounding rock of the water diversion tunnel and the support plate and the arc plate, only support plates or arc plates of different specifications can be replaced, which limits the scope of application and has low flexibility of use. For this reason, the present application proposes a water-rich and broken surrounding rock reinforcement device for a water diversion tunnel. Utility Model Content

[0027] Working principle: When reinforcing the water-rich broken surrounding rock of the water diversion tunnel, first adjust the support height and support width of the arc-shaped reinforcement plate 101 according to the height and width of the water-rich broken surrounding rock of the water diversion tunnel. When adjusting the support height, turn the two knobs 17 in the positive direction. The knobs 17 drive the corresponding internal threaded tube 15 to rotate. The internal threaded tube 15 rotates on the corresponding first screw 16 and drives the first screw 16 to move upward. The first screw 16 drives the corresponding support plate 100 to slide upward on the positioning plate 14. , the support plate 100 drives the corresponding arc-shaped reinforcement plate 101 to move upward, and the two arc-shaped reinforcement plates 101 simultaneously drive the arc-shaped bendable reinforcement plate 2 to move upward. When the top of the arc-shaped bendable reinforcement plate 2 is in close contact with the middle position of the top inner wall of the water-rich broken surrounding rock of the water diversion tunnel, the knob 17 is stopped from being rotated. Under the thread locking force between the internal threaded tube 15 and the corresponding first screw 16, the support plate 100 is fixed, thereby achieving the height fixation of the arc-shaped reinforcement plate 101 and the arc-shaped bendable reinforcement plate 2;

[0028] When the support width is adjusted, the two first T-shaped compression bolts 5 are rotated in the opposite direction to separate them from the arc-shaped bendable reinforcement plate 2, thereby releasing the fixation between the arc-shaped bendable reinforcement plate 2 and the arc-shaped reinforcement plate 101, and then the arc-shaped reinforcement plate 101 can be moved in the direction away from each other, and the arc-shaped reinforcement plate 101 drives the corresponding T-shaped slide rail 4 to slide in the slider 3. In the process of moving the arc-shaped reinforcement plate 101, in order to make its curvature adapt to the top inner wall of the water-rich crushed surrounding rock of the water diversion tunnel, the arc-shaped bendable reinforcement plate 2 can be bent and adjusted. When the sides of the two arc-shaped reinforcement plates 101 that are away from each other are in contact with the two sides of the top inner wall of the water-rich crushed surrounding rock of the water diversion tunnel, the movement of the arc-shaped reinforcement plate 101 is stopped, and the first T-shaped compression bolt 5 is rotated forward to move it until it is in close contact with the arc-shaped bendable reinforcement plate 2. Under the action of the friction between a T-shaped compression bolt 5 and the arc-shaped bendable reinforcement plate 2, the fixation between the arc-shaped bendable reinforcement plate 2 and the arc-shaped reinforcement plate 101 can be achieved, thereby achieving the adjustment of the support width. After the adjustment, the entire device can be slightly moved so that the support plate 100, the arc-shaped bendable reinforcement plate 2 and the two arc-shaped reinforcement plates 101 are all tightly fitted with the inner wall of the water-rich broken surrounding rock of the water diversion tunnel. At this time, the support plate 100, the arc-shaped bendable reinforcement plate 2 and the two arc-shaped reinforcement plates 101 perform preliminary reinforcement on the inner wall of the water-rich broken surrounding rock of the water diversion tunnel. After reinforcement, the base 102 can be fixed to the ground with external bolts. The support height and support width of the entire device can be adjusted according to the size of the water-rich broken surrounding rock of the water diversion tunnel, thereby improving the applicability and flexibility of the entire device.

[0029] Then, the four second T-shaped compression bolts 12 are rotated in the opposite direction to move them out of the corresponding slots, releasing the fixation of the movable plate 9. At this time, the movable plate 9 can be moved in the direction away from each other to drive the corresponding arc-shaped reinforcement plate 10 to move. The arc-shaped reinforcement plate 10 drives the corresponding anti-slip rubber to move to squeeze the arc-shaped reinforcement plate 101. When it is squeezed to a certain position, the movable plate 9 can be stopped and the second T-shaped compression bolt 12 can be rotated forward to move it into the aligned slot to fix the movable plate 9. If the second T-shaped compression bolt 12 is not aligned with the nearest slot, the T-shaped screw 8 can be rotated forward. While the T-shaped screw 8 rotates, it drives the connecting plate 7 to move upward. The connecting plate 7 drives the two arc-shaped reinforcement plates 10 to move upward through the two guide plates 11 and the two movable plates 9 in turn. The arc-shaped reinforcement plate 10 moves upward At the same time, an extrusion force is generated with the corresponding arc-shaped reinforcement plate 101. Under the extrusion force, the arc-shaped reinforcement plate 10 moves toward the direction close to the connecting plate 7, and the arc-shaped reinforcement plate 10 drives the corresponding movable plate 9 to move. The movable plate 9 drives the corresponding second T-shaped compression bolt 12 to move toward the direction close to the connecting plate 7 until it is aligned with the nearest slot. The rotation of the T-shaped screw 8 can be stopped, and the second T-shaped compression bolt 12 is rotated forward to move into the aligned slot. At this time, the two arc-shaped reinforcement plates 10 respectively extrude and reinforce the two arc-shaped reinforcement plates 101, thereby further reinforcing the inner wall of the water-rich broken surrounding rock of the water diversion tunnel. The double-layer reinforcement method is used to improve the reinforcement stability, and the position of the two arc-shaped reinforcement plates 10 is adjustable, which can be used to extrude and reinforce the adjusted arc-shaped reinforcement plate 101, thereby improving the flexibility of use.

[0030] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
