Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example: Figures 1-5 As shown, this utility model provides a waterproof tunnel lining structure, including two side plates 1. A top arc plate 2 is detachably provided on the upper side of the side plate 1. Both the side plate 1 and the top arc plate are made of high-strength, corrosion-resistant reinforced concrete. Several arc-shaped drainage grooves 21 are formed on the upper surface of the top arc plate 2. Several vertical drainage grooves 11 are formed on the outer side of the side plate 1, and the vertical drainage grooves 11 are interconnected with their corresponding arc-shaped drainage grooves 21. A baffle 12 is fixedly installed inside each vertical drainage groove 11. A water storage box 3 is provided on the lower inner side of the side plate 1, and a water guide frame 31 is fixedly installed on one side of the water storage box 3. One end of the water guide frame 31 is connected to the corresponding vertical drainage groove 11. A through groove 32 is formed inside the side plate 1 to cooperate with the water guide frame 31. The water guide frame 31 is fitted into the through groove 32. Fixing blocks 33 are symmetrically fixed on both sides of the water storage box 3, and the fixing blocks 33 are connected to the corresponding vertical drainage grooves 11. The side panels 1 are connected by bolts. A waterproof strip 34 is movably bonded to the outer surface of the water guide frame 31. The waterproof strip 34 is made of EPDM rubber and has excellent weather resistance, ozone resistance and waterproof sealing performance. The waterproof strip 34 is movably fitted to the corresponding side panel 1. When water comes into contact with the top arc plate 2, the water will first flow into the arc-shaped drainage groove 21 on the top arc plate 2. Since the arc-shaped drainage groove 21 is connected to the vertical drainage groove 11 on the outer side of the side panel 1, the water flows into the vertical drainage groove 11 along the connecting channel. In the vertical drainage groove 11, the water flow will be blocked by the baffle 12. Then the water flow enters the water storage box 3 at the lower inner side of the side panel 1 through the water guide frame 31. A through groove 32 is provided between the water guide frame 31 and the side panel 1. The waterproof strip 34 on the outer surface of the water guide frame 31 is movably fitted to the side panel 1 to ensure the sealing of the connection and prevent water leakage.

[0021] A frame 51 is fixedly provided on the inner side of the side panel 1, and a waterproof soft plate 5 (ethylene-vinyl acetate copolymer) is installed in the frame 51. The waterproof soft plate 5 is movably attached to the top arc plate 2. The waterproof soft plate 5 is installed in the frame 51 on the inner side of the side panel 1, and the waterproof soft plate 5 is movably attached to the top arc plate 2, forming an effective waterproof barrier to prevent water that may penetrate from the inside.

[0022] The outer surfaces of the side plates 1 and the top surface arc plates 2 are fixedly provided with reinforcing rods 4 and reinforcing arc rods 41, and the reinforcing arc rods 41 are fixedly connected with the corresponding reinforcing rods 4, and the adjacent reinforcing rods 4 and reinforcing arc rods 41 are fixedly provided with reinforcing columns 42.

These structures work together to improve the strength of the entire tunnel lining waterproof structure, so that it can withstand external pressure and impact.

[0023] The lower surfaces of the top surface arc plates 2 are symmetrically fixedly provided with insertion columns 22, and the insertion columns 22 are inserted into the corresponding side plates 1. The two sides of the side plates 1 and the top surface arc plates 2 are symmetrically provided with recesses 23, and the recesses 23 are clamped with connecting blocks 24. The connecting blocks 24 are connected with the corresponding side plates 1 and top surface arc plates 2 through bolt cooperation. The side plates 1 and the top surface arc plates 2 are connected with each other through the structures such as the insertion columns 22, the recesses 23 and the connecting blocks 24, and are fixed at the connection through bolts. These connecting structures are tightly matched, reducing the generation of gaps and reducing the possibility of external moisture penetration. At the same time, the waterproof strips 34 on the outer surfaces of the water guide frames 31 further enhance the waterproof performance between the side plates 1 and the water guide frames 31.

[0024] Working principle: when water flow contacts the top surface arc plate 2, the water flow first flows into the arc-shaped drainage groove 21 on the top surface arc plate 2. Since the arc-shaped drainage groove 21 and the vertical drainage groove 11 on the outer side of the side plate 1 are interconnected, the water flow flows into the vertical drainage groove 11 along the communication channel. In the vertical drainage groove 11, the water flow is blocked by the baffle 12, and then the water flow enters the water storage box 3 in the lower part of the inner side of the side plate 1 through the water guide frame 31. The water guide frame 31 is provided with a through groove 32 between the water guide frame 31 and the side plate 1, and the waterproof strip 34 on the outer surface of the water guide frame 31 is movably attached to the side plate 1, ensuring the sealing performance of the connection to prevent water leakage.

[0025] The clamping frame 51 on the inner side of the side plate 1 is clamped with the waterproof soft plate 5, and the waterproof soft plate 5 is movably attached to the top surface arc plate 2, forming an effective waterproof barrier to prevent water from penetrating from the inside.

[0026] The side plates 1 and the top surface arc plates 2 are connected with each other through the structures such as the insertion columns 22, the recesses 23 and the connecting blocks 24, and are fixed at the connection through bolts. These connecting structures are tightly matched, reducing the generation of gaps and reducing the possibility of external moisture penetration. At the same time, the waterproof strips 34 on the outer surfaces of the water guide frames 31 further enhance the waterproof performance between the side plates 1 and the water guide frames 31.

[0027] The outer surface of the side plate 1 and the top surface arc plate 2 is provided with reinforcing rods 4, reinforcing arc rods 41 and reinforcing columns 42, the reinforcing rods 4 and the reinforcing arc rods 41 are fixedly connected with each other to form a stable support frame, and the reinforcing columns 42 further enhance the stability of the frame, and the structures jointly act to improve the strength of the whole tunnel lining waterproof structure, so that the tunnel lining waterproof structure can withstand external pressure and impact.
