Description

Technical Field

[0001] The present invention relates to the technical field of tunnel waterproofing, in particular to a tunnel waterproofing structure and a waterproofing construction method thereof. Background Art

[0002] A tunnel is an engineering structure buried in the ground and is a form of human utilization of underground space. Tunnels can be divided into traffic tunnels, hydraulic tunnels, municipal tunnels, mining tunnels, and military tunnels.

[0003] When building a tunnel, it is necessary to open the entrance first and then install the supporting frame. Since the overall distance of the tunnel is relatively long, the supporting frame is installed by splicing it with each other. A large amount of water stains will penetrate into the mountain, and most of them will enter the tunnel through the gaps between the supporting structures. In the long run, it will cause a certain degree of damage to the supporting structure.

[0004] However, the existing joint waterproof structure has the following problems: Most existing tunnel waterproofing structures are achieved by applying a large amount of waterproof material at the connection between two supporting structures and using glue to fix the two together. However, as the tunnel is used for a longer time, the glue will dry out due to long-term contact with air, causing cracks in the gaps, causing the waterproof material to fall off, and further allowing water to continue to flow into the tunnel through the gaps.

[0005] Therefore, we propose a tunnel waterproof structure and its waterproof construction method to solve the problems raised above. Summary of the Invention

[0015] Preferably, a plurality of arc-shaped water squeezing strips are evenly arranged on one side of the tightening belt close to the water-absorbing sponge.

[0016] A waterproof construction method for a tunnel waterproof structure comprises the following steps: S1: First, determine the size of the concrete arch according to the size of the tunnel entrance to be explored. Next, fix the absorbent sponge in the arched water blocking groove, cover the outside of the absorbent sponge with a tightening belt, and wrap both sides of the belt around the winding rollers. S2: Next, the two adjacent concrete arch holes are joined together by external force, and the double-layer rubber pad is squeezed into the inner cavity of the double-layer card slot on the adjacent side, so that the gap between the two concrete arch holes can be fully filled after joining; S3: In addition, the elevated hole frame can be placed on the outside of the adjacent concrete arch hole, and the arched water blocking groove can be accommodated between the inner cavity of the elevated hole frame, so as to isolate a small amount of water that penetrates into the inner cavity of the elevated hole frame, and the water can be directed into the inlet and outlet grooves for drainage under the arrangement of the water outlet and drainage holes; S4: The water-absorbing sponge can absorb the water that penetrates into the inner cavity of the arched water-blocking groove. When the amount of water is large, the servo motor can be started to drive the rotating shaft to rotate, and the rotation of the rotating shaft drives the winding roller to rotate, so that the tightening belt can be wound and tightened, and then the elastic force of the tightening belt can be used to quickly squeeze out the water in the water-absorbing sponge. S5: When the servo motor is working, the hydraulic push rod can be activated to push the lifting plate to move back and forth. The vertical rod can drive the first ball to knock and vibrate the tightening belt. At the same time, the connecting rod can also drive the second ball to move back and forth and knock and vibrate the filter to improve drainage efficiency. S6: When inspection and maintenance are required, the staff can pull the cover up and open the inspection port to operate.

[0017] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention drives the winding roller to rotate by a servo motor, thereby tightening and loosening the tightening belt. When the amount of water that penetrates is large, the servo motor can be used to drive the tightening belt to tighten and squeeze the water-absorbing sponge. The setting of the arc-shaped water-squeezing strip can further improve the water squeezing effect of the water-absorbing sponge. The water-absorbing sponge is first used to absorb the water that penetrates into the inner cavity of the arched water-blocking groove, and then the tightening belt is used to squeeze the water in the water-absorbing sponge through the water outlet and drainage holes, thereby improving the water adsorption and discharge efficiency, and effectively solving the problem of poor tunnel waterproof penetration effect.

[0018] 2. The present invention, through the provision of double-layer card slots and double-layer rubber pads, can first push two adjacent concrete arch holes together, and then squeeze the double-layer rubber pad on one side into the inner cavity of the double-layer card slot under the action of external force, so as to fully fill the connecting gap between the two concrete arch holes by utilizing the elastic force of the double-layer rubber pad, effectively solving the problem of existing waterproof structures in which concrete arch holes are assembled by glue and then waterproof material is applied to the gaps of the arch holes, resulting in the arch holes falling off after the glue weathers, causing the waterproof coating to fall off.

[0019] 3. The present invention can insert the concrete arch hole on one side into the elevated hole frame on the adjacent side by setting the elevated hole frame and the arched water blocking groove. At the same time, the arched water blocking groove can be accommodated in the inner cavity of the elevated hole frame, thereby preventing water dripping from the inner wall of the tunnel from directly falling between the gaps in the arch hole. The arched water blocking groove can block a small amount of moisture that penetrates into the inner cavity of the elevated hole frame, preventing moisture from flowing into the connecting gaps of the arch hole, thereby further improving the waterproof performance of the tunnel.
