[0042] A karst tunnel water inrush emergency treatment method of this embodiment uses the karst tunnel water inrush emergency treatment device as described above, and includes the following steps:

[0043] Step 1: The staff places the water retaining plate 1 at a preset position and supports it through the support seats 2 located on both sides of the water retaining plate 1;

[0044] Step 2: Drive the arc plate 6 and the insertion rod 7 to rotate relative to the reinforcement box 3 through the angle adjustment component so that the inclination angle of each insertion rod 7 is at a preset angle;

[0045] Step 3: After the angle of the rod 7 is adjusted, the rod 7 is driven to move relative to the arc plate 6 by pushing the insertion structure so that the rod 7 is inserted into the ground in the tunnel, and the water retaining plate 1 is supported and limited by a plurality of rods 7.

[0046] Working principle: The staff puts the water retaining plate 1 to the preset position, and supports it through the support seats 2 on both sides of the water retaining plate 1 to prevent the water retaining plate 1 from tilting during placement. The angle adjustment component drives the arc plate 6 and the plug rod 7 to rotate relative to the reinforcement box 3, so that the inclination angle of each plug rod 7 is at a preset angle. After the angle adjustment of the plug rod 7 is completed, the plug rod 7 is driven to move relative to the arc plate 6 by pushing the insertion structure, so that the plug rod 7 is inserted into the ground in the tunnel. The water retaining plate 1 is supported and limited by a number of plug rods 7, which increases the stability of the water retaining plate 1 and reduces the possibility of the water retaining plate 1 tilting after being hit by the gushing water and soil, protects personnel and equipment, and improves safety.

[0047] The compression spring 18 is initially in a compressed state. The compression spring 18 applies pressure to the slider 16 so that the end of the slider 16 is tightly inserted into the slide groove 15. The detachable driving mechanism drives the rotating shaft 5 to rotate, and the rotating shaft 5 drives the fixed seat 14 to rotate. The fixed seat 14 drives the fixed ring 12 to rotate synchronously through the slider 16. The fixed ring 12 drives the rotating sleeve 11 and the first bevel gear 19 to rotate. The first bevel gear 19 drives the screw rod 8 to rotate through the second bevel gear 20. The screw rod 8 drives the insertion rod 7 to move relative to the arc plate 6, and the insertion rod 7 drives the support part 30 to slide relative to the guide column 31 and the arc plate 6. When the support part 30 and the positioning plate 32 are in contact or the resistance encountered by the continuous movement of the insertion rod 7 is greater than the preset value, the insertion rod 7 stops moving. The seat 14 and the slider 16 continue to rotate, and the end of the slider 16 slides on the inclined surface of the slide groove 15, and finally the end of the slider 16 slides out of the slide groove 15, and the slider 16 rotates relative to the fixed ring 12. When it is necessary to pull the insertion rod 7 out of the ground in the tunnel, the detachable drive mechanism drives the rotating shaft 5 to rotate in the opposite direction. When the slider 16 slides back into the corresponding slide groove 15, as the fixed seat 14 continues to rotate, the slider 16 contacts the inner wall of the side of the slide groove 15 that is not the inclined surface, and the slider 16 cannot slide out of the slide groove 15. As the fixed seat 14 continues to rotate, the fixed seat 14 drives the slider 16 and the fixed ring 12 to rotate synchronously, so that the insertion rod 7 moves toward the arc plate 6, so that the insertion rod 7 is pulled out of the ground in the tunnel;

[0048] The servo motor 34 drives the block 36 to rotate, and the block 36 drives the rotating shaft 5 to rotate through the fixed plate 33. When the servo motor 34 needs to be disassembled, the staff drives the movable plate 42 and the positioning plate 41 to move, and the second tension spring 43 is in a tensioned state, so that the positioning plate 41 is pulled out from the positioning hole 39, and the position restriction of the plug plate 37 is released, so that the plug plate 37 can be pulled out from the second groove 40. The staff drives the servo motor 34 and the plug plate 37 to move, so that the plug plate 37 is pulled out from the second groove 40, and the block 36 slides out of the card slot 35, and the servo motor 34 is removed.

[0049] When the insertion angle of the insertion rod 7 needs to be changed, the staff drives the insertion rod 7 and the arc plate 6 to slide relative to the reinforcement box 3, and the arc plate 6 slides relative to the arc strip 21 and the connecting block 22. The arc strip 21 and the connecting block 22 are designed to make the arc plate 6 rotate smoothly. The arc plate 6 drives the fixed sleeve 23 to rotate relative to the rotating shaft 5, and the second bevel gear 20 rolls relative to the first bevel gear 19. When the angle of the insertion rod 7 is adjusted, the first tension spring 27 is in a tensioned state, and the first tension spring 27 applies tension to the support plate 26 and the prism 25. The pressing plate 24 is in close contact with the fixing sleeve 23 to preliminarily fix the insertion rod 7 and the arc plate 6 relative to the reinforcement box 3. The staff adjusts the positions of other insertion rods 7 and arc plates 6 in turn. When the positions of several insertion rods 7 are adjusted, the pressing seat 28 is driven downward by the hydraulic telescopic rod 29 to make the pressing seat 28 press the support plate 26, thereby increasing the pressure applied by the pressing plate 24 to the fixing sleeve 23, and performing secondary fixation on the positions of the fixing sleeve 23, the arc plate 6 and the insertion rod 7 to prevent the arc plate 6 and the insertion rod 7 from tilting and shaking relative to the reinforcement box 3.
