During the operation of the laying device, the pump body 8 can absorb part of the waterproof material. , and transfer it to the laying roller 30, and the waterproof material is sprayed on the inner wall surface of the tunnel from the discharge hole 7 on the laying roller 30. In this link, the carrier 29 drives the support frame 34, and the support frame 34 is forced to drive the smoothing brush roller 35 to move, and the smoothing brush roller 35 is forced to rotate to smooth the waterproof material sprayed on the inner wall surface of the tunnel. At the same time, the waterproof material sprayed on the inner wall surface of the tunnel from the discharge hole 7 on the laying roller 30, the excess waterproof material will flow into the arc guide groove 31, the arc guide groove 31 collects the waterproof material, and then flows into the filter box 37 through the drainage pipe 32, the filter net in the filter box 37 intercepts the impurities, and then the waterproof material flows back to the liquid storage tank 13.

[0044] The following steps are involved:

[0045] S1: The waterproof material is injected into the liquid storage tank 13, the mobile trolley 1 is turned on, the drive motor 3 and the pump body 8 are operated simultaneously, the mobile trolley 1 drives the entire device to move in the tunnel, and the drive motor 3 drives the push plate 6 on the outer side of the first rotating shaft 4 to discharge the waterproof material from the first through hole 2 when the mobile trolley 1 moves, and the rubber plate 10 on the outer side of the roller 18 is driven by the transmission belt 5 to rotate synchronously;

[0046] S2: When the surface of the rubber sheet 10 contacts the waterproof material, the rotating roller 18 rotates, so that the waterproof material can be evenly laid on the ground. At the same time, the elastic effect of the telescopic spring rod 9 can effectively make the rubber sheet 10 better contact the ground and the waterproof material to complete the laying of the ground. The pump body 8 absorbs part of the waterproof material and transfers it to the laying roller 30 to spray it on the inner wall surface of the tunnel through the discharge hole 7;

[0047] S3: During this period, the connecting column 28 is compressed by the spring 27 between the two connecting rods 26, pushing the laying roller 30 to contact the inner wall surface of the tunnel, and starting the double-axis motor 20 to drive the gear 22 outside the second rotating shaft 21 to mesh with the surface of the arc-shaped toothed plate 12;

[0048] S4: The limiting block 23 slides in the limiting groove 17 through the insert block 24 to improve the limiting and guiding effects, so that the surface of the laying roller 30 can reciprocate in the lateral arc on the upper side of the arc plate 11, and the inner wall surface of the tunnel is effectively and evenly laid.

[0049] Working principle:

[0050] The first step is to inject the waterproof material into the liquid storage tank 13. This liquid storage tank has been carefully designed and has sufficient capacity to accommodate a large amount of waterproof material to ensure sufficient material supply during the entire paving process. Then, start the mobile cart 1, drive motor 3 and pump body 8 to run at the same time. The mobile cart 1 has a solid structure and a good power system, which can stably drive the entire device to move in the tunnel. As the mobile cart 1 slowly moves forward, it provides a reliable mobile platform for the entire paving work.

[0051] In the second step, the driving motor 3 starts to work while the mobile trolley 1 moves. It drives the first rotating shaft 4 to rotate with powerful power, and the pushing plate 6 outside the first rotating shaft 4 also starts to move. The pushing plate 6 is precisely designed and manufactured, and can effectively discharge the waterproof material from the first through hole 2. In this process, the stable output of the driving motor 3 ensures that the pushing plate 6 moves smoothly and powerfully, so that the waterproof material can be smoothly pushed out of the liquid storage tank 13.

[0052] In the third step, through the transmission action of the transmission belt 5, the rubber sheet 10 outside the roller 18 also starts to rotate synchronously. When the surface of the rubber sheet 10 contacts the waterproof material, as the roller 18 rotates, it can evenly lay the waterproof material on the ground. The telescopic spring rod 9 has good elasticity and transmission performance. On the one hand, it can effectively transmit the power of the drive motor 3 to the roller 18. On the other hand, its own elastic action can make the rubber sheet 10 better contact with the ground and the waterproof material. This elasticity enables the rubber sheet 10 to automatically adjust according to the unevenness of the ground, ensuring that the waterproof material can fit tightly on the ground, thereby completing the ground laying work.

[0053] The fourth step, in this process, the pump body 8 is also actively playing a role. The pump body 8 can absorb part of the waterproof material and transfer it to the laying roller 30. The waterproof material is sprayed on the inner wall surface of the tunnel from the discharge hole 7 on the laying roller 30. In this link, the connecting column 28 plays an important role. The connecting column 28 uses the compression function of the spring 27 between the two connecting rods 26 to push the laying roller 30 tightly against the inner wall surface of the tunnel. The spring 27 has good elasticity and compression performance, and can automatically adjust the position and pressure of the laying roller 30 according to the shape and unevenness of the inner wall of the tunnel, ensuring that the waterproof material can be evenly sprayed on the inner wall surface of the tunnel.

[0054] The fifth step is to start the dual-axis motor 20. The dual-axis motor 20 has a powerful power output and can drive the gear 22 on the outside of the second rotating shaft 21 to rotate. The gear 22 is meshed with the surface of the arc-shaped toothed plate 12, thereby driving the entire paving device to move laterally on the upper side of the arc-shaped plate 11, and the limit block 23 slides in the limit groove 17 through the plug block 24, which can improve the limiting and guiding effects. This design enables the surface of the paving roller 30 to move back and forth in the lateral arc on the upper side of the arc plate 11, ensuring effective and uniform paving of the inner wall surface of the tunnel. The cooperation between the limit block 23 and the plug block 24 is precise and stable, which can effectively limit the moving range of the paving device and ensure the accuracy and high quality of the paving work.

[0055] The sixth step is that during the operation of the laying device, the pump body 8 can absorb part of the waterproof material and transfer it to the laying roller 30. The waterproof material is sprayed on the inner wall surface of the tunnel from the discharge hole 7 on the laying roller 30. In this link, the carrier 29 drives the support frame 34. The support frame 34 is forced to drive the smoothing brush roller 35 to move. The smoothing brush roller 35 is forced to rotate to smooth the waterproof material sprayed on the inner wall surface of the tunnel, thereby improving the flatness of the spraying. At the same time, the waterproof material sprayed on the inner wall surface of the tunnel from the discharge hole 7 on the laying roller 30, the excess waterproof material will flow into the arc guide groove 31, the arc guide groove 31 collects the waterproof material, and then flows into the filter box 37 through the drainage pipe 32. The filter net in the filter box 37 intercepts impurities, and then the waterproof material flows back to the liquid storage tank 13, thereby effectively improving the utilization of the waterproof material and saving costs.
