Description

Technical Field

[0001] The present invention relates to the technical field of tunnel construction, and in particular to a device for blocking and draining water from tunnel gushing. Background Art

[0002] Tunnel blasting construction is a construction method that uses the energy of explosive explosions to break up rock mass to form tunnels or caverns. For areas with poor geology and special rocky terrain, advance drilling should be used before construction to explore the geological conditions and formulate measures to deal with sudden large-scale water inrush. When water inrush occurs, it is necessary to seal the water holes and drain the water, otherwise the water inrush hole will become larger and larger with the flow of water, resulting in major hidden dangers in safety construction risks. At present, for tunnel water inrush, it is usually necessary to first concentrate the water into a water pit, and then use a water pump to pump it out of the cave. Therefore, it is necessary to wait until all the water has flowed out and the water has been drained before continuing with subsequent construction, which affects the overall construction progress.

The base 11 and the top seat 13 are both arranged horizontally, and the vertical seat 12 is telescopically arranged between the base 11 and the top seat 13 in the vertical direction. Specifically, the vertical seat 12 includes a lower support 121 and an upper support 122 slidably installed in the lower support 121. The lower support 121 is welded to the top of the base 11, and the upper support 122 is welded to the bottom of the top seat 13. The lower support 121 is provided with a lifting electric cylinder 123 for driving the upper support 122 to move up and down. The lifting electric cylinder 123 drives the upper support 122 to move in the vertical direction, that is, the top seat 13 can be adjusted to a specified height for the convenience of plugging operation.

The driving seat 22 is welded to the piston rod of the driving electric cylinder 21. The driving seat 22 is provided with a clamping mechanism 3. The outer tube 4 is provided with a flange 41 for clamping by the clamping mechanism 3. By clamping the clamping mechanism 3 on the flange 41, the relative position between the outer tube 4 and the driving seat 22 can be fixed. Then, the driving electric cylinder 21 drives the driving seat 22 to move along the length direction of the top seat 13, so that the outer tube 4 can be driven to be inserted into the water gushing hole.

[0030] Reference Figure 1 , Figure 2 As shown, the clamping mechanism 3 includes a support seat 31, a driving motor 32, a double-axis lead screw 33, two driving blocks 34 and two clamping seats 35. A driving groove 311 is provided on the support seat 31. The double-axis lead screw 33 is rotatably arranged in the driving groove 311. The driving motor 32 is fixedly arranged at one end of the support seat 31 and the output shaft of the driving motor 32 is coaxially connected with the double-axis lead screw 33.

The two clamping seats 35 are fixedly arranged on the top of the two driving blocks 34 in a one-to-one correspondence. The driving motor 32 is started to drive the double-axis lead screw 33 to rotate, and the two driving blocks 34 are driven to move in a direction close to each other at the same time. When the driving block 34 moves, it can drive the two clamping seats 35 to press against the flange 41 of the outer tube 4 at the same time. In order to prevent relative rotation between the outer tube 4 and the clamping seat 35 after being pressed together, stop blocks 411 are provided on both sides of the flange 41, and stop grooves 351 for inserting the stop blocks 411 are opened on the two clamping seats 35.

When the driving seat 22 drives the clamping mechanism 3 to move as a whole, the limiting protrusion 352 abuts against the end face of the flange 41 to ensure that the outer tube 4 is smoothly pushed into the water gushing hole.

The inner tube 5 is provided with a first driving ring 51 for driving the plurality of abutment blocks 421 to move simultaneously toward the outside of the outer tube 4. The outer abutment 43 is an abutment disk. An external thread is provided at one end of the outer tube 4 outside the water gushing hole. A threaded hole is provided on the abutment disk and is threadedly connected to the external thread of the outer tube 4.

[0032] The outer tube 4 is inserted into the water gushing hole through the driving mechanism 2 and the end of the outer tube 4 is extended from the end of the water gushing hole away from the tunnel face. Then, by rotating the inner tube 5 and causing relative movement between the inner tube 5 and the outer tube 4, the first driving ring 51 is driven to move to drive multiple abutment blocks 421 to move toward the outer tube 4 at the same time. Then, the outer tube 4 is pulled out of the water gushing hole for a distance and the abutment blocks 421 are abutted against the end of the water gushing hole away from the tunnel tunnel face. Then, by rotating the abutment plate and causing the abutment plate to abut against the end of the water gushing hole toward the tunnel tunnel face, the position of the outer tube 4 can be fixed, so that the clamping mechanism 3 can be removed from the outer tube 4 to facilitate the blocking of the next water gushing hole.
