[0046] In detail, in recent years, with the development of the economy, the requirements for transportation have become increasingly higher, and tunnels have become an important symbol of a city's development level. Since underground structures are usually covered by soil or buried at a certain depth below the ground, they must withstand the infiltration and erosion of groundwater. This is a prerequisite for ensuring structural safety. Therefore, the layout of the waterproof layer is particularly important. Before laying the waterproof layer, waterproof concrete needs to be sprayed during the initial support, and a quick-setting agent is added to the concrete to accelerate the solidification of the waterproof concrete. This can effectively isolate the gushing water and create good conditions for the waterproof construction inside the tunnel. After the concrete solidifies, mortar is used to level the uneven parts during the initial support process, and the protruding parts of the surface are chiseled out and the concave parts are smoothed with mortar. The protruding anchor heads should also be cut off and processed to prevent puncture of the membrane. After the above construction treatment is completed, the device can be transported to the tunnel.

[0047] Preferably, the ends of the No. 1 conveyor roller 12 and the No. 2 conveyor roller 13 are provided with threads, and the inner wall of the receiving tube 11 is also provided with threads. In the initial state, the No. 1 conveyor roller 12 and the No. 2 conveyor roller 13 are inserted into the receiving tube 11 and screwed into the receiving tube 11, and the movable block 6 is located at the end of the stroke on one side of the arc-shaped rack plate 5, so that the No. 1 conveyor roller 12 is located above the No. 2 conveyor roller 13. When it is necessary to lay a waterproof layer, a person can stand on the cross plate 2. At this time, the device is transported to the required construction position of the tunnel, and the No. 1 conveyor roller 12 and the No. 2 conveyor roller 13 are taken out from the receiving tube 11. At the same time, the geotextile and waterproof board required for the waterproof layer are respectively wound on the No. 1 conveyor roller 12 and the No. 2 conveyor roller 13, and the geotextile and waterproof board are passed through the guide assembly. Since the geotextile needs to be laid first and then the waterproof board during the construction of the waterproof layer, the geotextile is continued to be controlled on the support roller 19. Under the action of the support assembly, the support The support roller 19 presses the geotextile against the inner wall of the tunnel, and the workers can fix the end of the geotextile to the inner wall of the tunnel with nails. When the fixation is completed, the motor 7 works, driving the transmission rod 8 to rotate, thereby driving the gear 9 to rotate. Since the gear 9 is engaged with the arc-shaped rack plate 5, the movable block 6 slides on the arc-shaped rack plate 5, thereby driving the support plate 10 to move, thereby driving the No. 1 conveyor roller 12 and the No. 2 conveyor roller 13 to move. Under the action of the support plate 10, the support roller 19 is controlled by the support assembly to slide along the inner wall of the tunnel. At this time, the geotextile wrapped on the No. 1 conveyor roller 12 will be continuously released and adhere to the inner wall of the tunnel. Workers can fix the laid geotextile with nails during the laying process until the movable block 6 moves to the end of the stroke on the other side of the arc-shaped rack plate 5. The geotextile is laid. The No. 1 conveyor roller 12 is located below the No. 2 conveyor roller 13. At this time, the worker can cut the geotextile to separate the geotextile from the support roller 19.

[0048] Among them, after the geotextile is laid, the waterproof board needs to be laid. Under the action of the guide component, the waterproof board will be released and move to the matching position of the support roller 19. Under the action of the support roller 19, the waterproof board will be pressed against the geotextile. At this time, the motor 7 can control the transmission rod 8 to reverse, so that the movable block 6 moves toward the initial position to lay the waterproof board.

[0049] See also Figures 1-4 、 Figure 6-Figure 8, support roller 19, is arranged on the fixed plate 3, and the fixed plate 3 is provided with a support assembly connected to the support roller 19 and the driving mechanism, and the driving mechanism can drive the support roller 19 to move through the support assembly, and the support assembly includes a hollow rod 14 installed on the support plate 10 and connected to the guide assembly, and a movable rod 16 is movably installed in the hollow rod 14, and a No. 1 spring 18 is provided in the hollow rod 14 to abut against the movable rod 16; the support assembly also includes a slot 15 opened on the side wall of the hollow rod 14, and a limiting rod 17 engaged with the slot 15 and hollow is provided on the movable rod 16, and the limiting rod 17 is connected to the limiting mechanism and the regulating mechanism, and the movable rod 16 is rotatably connected to the support roller 19.

[0050] It should be noted that in order to ensure that the geotextile and waterproof sheet maintain a certain degree of tension during laying, it is necessary to guide the geotextile and waterproof sheet during laying. When the waterproof layer needs to be laid, the geotextile is placed on the support roller 19. In the initial state, the No. 1 spring 18 is in a compressed state, so that the movable rod 16 is located in a position away from the hollow rod 14, so that the geotextile is controlled to press against the inner wall of the tunnel through the support roller 19. When laying is required, the motor 7 works and drives the support roller 19 to rotate around the transmission rod 8. Under the action of the No. 1 spring 18, the movable rod 16 is in a compressed state. The movable rod 16 is located in a position away from the hollow rod 14, so that the geotextile is controlled to press against the inner wall of the tunnel through the support roller 19. When laying is required, the motor 7 works and drives the support roller 19 to rotate around the transmission rod 8. Under the action of the limiting mechanism, ensure that the support roller 19 always controls the geotextile to abut against the inner wall of the tunnel. When the geotextile is laid, the support roller 19 is separated from the geotextile under the action of the limiting mechanism, and the No. 1 spring 18 is compressed by the movable rod 16. At the same time, under the action of the regulating mechanism and the guiding assembly, the waterproof board is placed on the support roller 19. Under the action of the limiting mechanism, the No. 1 spring 18 is elastically released, and the waterproof board is controlled to abut against the inner wall of the tunnel through the support roller 19. At this time, the motor 7 will drive the transmission rod 8 to reverse to lay the waterproof board through the support roller 19.

[0051] See also Figure 1-Figure 5 、 Figure 8 、 Figure 9The limit mechanism is arranged on the cross plate 2 and is connected to the support assembly. The limit mechanism can drive the support roller 19 to move through the support assembly when the support roller 19 moves to the end of the stroke. The limit mechanism includes an arc limit block 4 installed on the cross plate 2 and symmetrically arranged. The end of the limit rod 17 away from the support roller 19 is movably installed with a sliding rod 33. The sliding rod 33 is provided with a limit wheel 35 that cooperates with the arc limit block 4. A reset assembly connected with the limit rod 17 and the sliding rod 33 is provided on the fixed plate 3, wherein the reset assembly includes a limit groove 32 opened on the end of the limit rod 17 toward the limit wheel 35, and a limit ring 34 is provided on the sliding rod 33 that engages with the limit groove 32. The limit rod 17 is sleeved with a No. 2 spring 36 that abuts against the limit ring 34.

[0052] Furthermore, the arc limit blocks 4 are symmetrically arranged, and the sides close to each other are arranged in an arc shape, and the side of the arc limit block 4 facing the ground is inclined. In the initial state, the arc limit block 4 and the limit wheel 35 are in a separated state, and the limit wheel 35 is located below the arc limit block 4. The second spring 36 is in a compressed state, so that the limit wheel 35 is located at the end of the stroke toward the limit rod 17. When it is necessary to lay the geotextile, the support plate 10 will rotate around the transmission rod 8, thereby driving the limit The limiting wheel 35 moves. When the limiting wheel 35 moves to abut the inclined surface of the arc-shaped limiting block 4, the limiting wheel 35 will move in the direction away from the limiting rod 17, causing the sliding rod 33 to move and drive the limiting ring 34 to move along the length direction of the limiting groove 32 to compress the No. 2 spring 36 to ensure that the limiting wheel 35 does not interfere with the arc-shaped limiting block 4, causing the movable rod 16 to move. When the geotextile is laid, it is necessary to control the separation of the geotextile and the support roller 19, and control the waterproof board to fit the support roller 19. At this time, the support plate 10 continues to move, and drives the movable rod 16 and the limiting wheel 35 to move. When the limiting wheel 35 moves to the position of contact with the arc-shaped limiting block 4, the limiting wheel 35 will slide along the arc surface, thereby driving the movable rod 16 to slide toward the inside of the hollow rod 14, so that the support roller 19 is separated from the geotextile. The movable rod 16 will also drive the guide assembly to move through the regulating mechanism, and drive the waterproof board to unfold through the limiting roller 24, so that the waterproof board can move smoothly to the position of contact with the support roller 19. When the limiting wheel 3 When the limiting wheel 35 moves to the position of separation from the arc-shaped limit block 4, the No. 1 spring 18 is elastically released and drives the supporting roller 19 to move in the direction away from the hollow rod 14 through the movable rod 16 until the supporting roller 19 presses the waterproof sheet against the geotextile. At this time, the motor 7 drives the transmission rod 8 to reverse and lays the waterproof sheet through the supporting roller 19. When the limiting wheel 35 moves to the position of contact with the inclined surface of the arc-shaped limit block 4, the limiting wheel 35 will not drive the movable rod 16 to move, ensuring that the supporting roller 19 will not be separated from the waterproof sheet.

[0053] See also Figure 1-Figure 3 、 Figure 6 The limiting roller 24 is symmetrically arranged on the fixed plate 3, and the fixed plate 3 is provided with a guide assembly connected to the supporting assembly and the limiting roller 24. The guide assembly includes a baffle 20 installed on the hollow rod 14 and symmetrically arranged. A rotating rod 21 is rotatably installed on the baffle 20, and a ratchet 22 is provided on the rotating rod 21. A belt 23 connected to the limiting roller 24 is sleeved on the rotating rod 21. The baffle 20 is rotatably connected to the limiting roller 24, and the ratchet 22 is connected to the regulating mechanism.

[0054] Furthermore, in order to place the geotextile and the waterproof sheet on the support roller 19 in sequence, it is necessary to automatically guide the next required laying object to the support roller 19 after the geotextile or waterproof sheet is laid. In the initial state, the geotextile and the waterproof sheet are respectively placed between the two baffles 20 and the limiting roller 24, and the geotextile is arranged on the support roller 19. When the geotextile is laid, the waterproof sheet needs to be laid. At this time, the movable rod 16 continues to move and drives the limiting rod 17 to move, so that the regulating mechanism moves. Under the action of the regulating mechanism, the limiting roller 24 abutting against the waterproof sheet is driven to rotate. Under the action of the limiting roller 24, the waterproof sheet is gradually released. Because the support roller 19 is in the position under the action of the limiting mechanism, Towards the end of the stroke in the hollow rod 14, therefore, the waterproof sheet will fall on the support roller 19 after being released a certain distance, and the limit rod 17 continues to move. Under the action of the limit mechanism, the No. 1 spring 18 is elastically released, causing the support roller 19 to move toward the inner wall of the tunnel and press the waterproof sheet against the geotextile. When the geotextile is laid, the control mechanism will drive the limit roller 24 in contact with the geotextile to rotate, and control the release of the geotextile to move the geotextile again to the position in contact with the support roller 19. Repeat the above steps to achieve automatic control of the waterproof sheet and the support roller 19 after the geotextile is laid, so as to ensure that the geotextile and the waterproof sheet cooperate with the support roller 19 in turn, which is convenient for the subsequent laying effect.

[0055] See also Figure 4-Figure 8 、 Figure 10The fixed plate 3 is also provided with a regulating mechanism connected to the guide assembly and the supporting assembly, and the regulating mechanism can drive the limiting roller 24 to rotate through the guide assembly. The regulating mechanism includes a cylinder 29 installed on the movable rod 16, and a movable plate 30 is provided on the output end of the cylinder 29. The movable plate 30 is provided with an inclined groove 31, and the fixed plate 3 is provided with a sliding assembly that cooperates with the inclined groove 31. The sliding assembly cooperates with the ratchet 22, wherein the sliding assembly includes a guide rail 25 installed on the limiting rod 17, and a sliding plate 26 is slidably installed in the guide rail 25. A symmetrically arranged ratchet plate 27 is provided on the sliding plate 26, and a support rod 28 engaged with the inclined groove 31 is provided on the ratchet plate 27, and the ratchet plate 27 cooperates with the ratchet 22.

[0056] In detail, in order to ensure that the limiting roller 24 does not rotate when the waterproof sheet and geotextile are laid, it is necessary to control the ratchet plate 27 and the ratchet wheel 22 to be in a separated state. In the initial state, under the action of the cylinder 29, the support rod 28 is located in the middle position of the inclined groove 31. Therefore, the sliding plate 26 is located in the middle position of the guide rail 25, and the ratchet plate 27 and the ratchet wheel 22 are in a separated state. When the geotextile is laid, the waterproof sheet needs to be laid. Therefore, it is necessary to control the limiting roller 24 that is in contact with the waterproof sheet to rotate. At this time, the cylinder 29 works to drive the movable plate 30 to move toward the direction of the support plate 10. Under the action of the inclined groove 31 and the support rod 28, the sliding plate 26 is driven to move along the length direction of the guide rail 25 and toward the second conveying roller 13. At this time, the limiting wheel 35 abuts against the arc limit block 4 and drives the movable rod 16 to move toward the hollow rod 14, thereby driving the guide rail 2 through the limiting rod 17 5 movement, so that the sliding plate 26 moves synchronously, under the action of the ratchet plate 27, the ratchet wheel 22 is driven to rotate, so as to drive the limiting roller 24 to rotate through the belt 23, thereby controlling the release of the waterproof sheet. When the limiting wheel 35 is separated from the arc-shaped limiting block 4, the waterproof sheet moves to the position cooperating with the support roller 19. Under the action of the No. 1 spring 18, the support roller 19 is reset and the ratchet plate 27 is moved toward the initial position. The ratchet wheel 22 does not rotate. Under the action of the cylinder 29, the sliding plate 26 is driven to reset, so that the support rod 28 returns to the middle position of the inclined groove 31 again, and the sliding plate 26 returns to the middle position of the guide rail 25. Similarly, when the waterproof sheet is laid, the cylinder 29 can control the sliding plate 26 to move toward the No. 1 conveying roller 12, so that the geotextile is released and moves to the position cooperating with the support roller 19. The above steps are repeated to achieve the effect of automatically controlling the geotextile and the waterproof sheet to cooperate with the support roller 19 in turn.

[0057] A method for using a tunnel mold lining waterproof layer working platform comprises the following steps:

[0058] Step 1: Wrap the geotextile around the No. 1 conveyor roller 12 and the waterproof sheet around the No. 2 conveyor roller 13. When construction is required, move the device to the required position, pass the geotextile through the guide assembly and wrap it around the support roller 19;

[0059] Step 2: Under the action of the support assembly, the geotextile on the support roller 19 is brought into contact with the inner wall of the tunnel. At this time, the drive mechanism works and drives the support roller 19 to slide along the inner wall of the tunnel through the support assembly, so that the geotextile is laid on the inner wall of the tunnel;

[0060] Step 3: After the geotextile is laid, the worker can cut the geotextile. Under the action of the limiting mechanism, the support assembly controls the support roller 19 to move away from the inner wall of the tunnel. Under the action of the regulating mechanism, the guide assembly is driven to move, thereby driving the limiting roller 24 to rotate, so as to guide the waterproof sheet to move toward the support roller 19.

[0061] Step 4: When the waterproof sheet moves to the position of abutting the support roller 19, the limiting mechanism will move toward the inner wall of the tunnel again through the support roller 19 via the support assembly, and control the waterproof sheet to abut against the inner wall of the tunnel. At this time, the driving mechanism drives the support roller 19 to rotate in the opposite direction through the support assembly to lay the waterproof sheet on the inner wall of the tunnel.
