Description

Technical Field

[0001] This invention relates to the technical field of tunnel waterproofing membrane laying equipment, and in particular to a tunnel folding waterproofing membrane laying trolley and its usage method. Background Technology

[0002] Waterproofing in underground engineering remains a major challenge. Groundwater and seepage are key factors affecting the performance, lifespan, and safety of tunnels. Groundwater reduces the mechanical properties of surrounding rock surfaces, deteriorating its integrity and stability, and worsening the tunnel environment. Groundwater plays a crucial role in many tunnel collapses. Seepage in tunnels affects the functionality and structural durability of subway systems. Furthermore, significant groundwater loss can cause a drop in the water table, soil consolidation and settlement, leading to problems such as building cracks. Large-scale groundwater drainage also increases operating costs, and in case of emergencies where drainage cannot be timely, it can jeopardize tunnel operation and equipment safety. Therefore, tunnel waterproofing is an extremely important aspect. To prevent leakage, tunnels require the installation of waterproofing materials, with waterproofing membranes being a key component. Currently, conventional tunnel waterproofing membrane installation is mostly done manually, requiring multiple workers on workbenches. This method is inefficient, results in uneven installation, and fails to guarantee the quality of the waterproofing membrane, thus failing to achieve complete waterproofing.

[0003] For example, CN102135001A, published on July 27, 2011, discloses a tunnel waterproofing membrane laying device that solves the problem of low construction quality due to high labor intensity in waterproofing membrane laying. The device includes a portal steel frame with external support rods. A reinforcing rod is fixed between two support rods. A guide tube is located above the two support rods, and a reinforcing rod is fixed between the two guide tubes. A chain box is fixed to each of the reinforcing rod and the reinforcing rod. A motor is located below the support rods, and chains are externally connected between the two chain boxes and the motor. A power gear is located on the output shaft of the motor. A laying trolley is located on the guide tube. The laying trolley includes a base, a lifting cylinder is mounted on the base, and a transmission gear is located below the base. A support seat is located at the other end of the lifting cylinder, and a rotating shaft passes through the support seat. However, in operation, the waterproofing membrane is prone to warping after being laid on the tunnel wall, resulting in poor laying performance. Summary of the Invention

Detailed Implementation

[0034] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0035] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0036] like Figure 1As shown, a tunnel folding waterproof membrane laying trolley includes an operating platform 1, a base plate 2 on the operating platform 1, a driving mechanism on the operating platform 1 for moving the base plate 2, a laying mechanism on the base plate 2 for laying the waterproof membrane, and a compaction mechanism on the base plate 2 for compacting the laid waterproof membrane. Specifically, the operating platform 1 is welded from channel steel, and the outer contour of the operating platform 1 is annular, which is adapted to the inner wall of the tunnel.

[0037] The operating platform 1 is moved into the tunnel, and the drive mechanism works to move the base plate 2 along the operating platform 1. Then, the laying mechanism on the base plate 2 moves along the inner wall surface of the tunnel to carry out the waterproof membrane laying work, which greatly improves the laying efficiency of the waterproof membrane and saves a lot of labor. When the base plate 2 moves, the rolling mechanism flattens the waterproof membrane on the inner wall of the tunnel, making the waterproof membrane laying more flat and improving the quality of the finished waterproof membrane.

[0038] Specifically, refer to Figure 1-2 The driving mechanism includes a rack 3 and a driving gear 4. The rack 3 is connected to the operating platform 1, and the driving gear 4 is connected to the base plate 2. The driving gear 4 and the rack 3 mesh. The driving gear includes a drive motor and a drive gear. The rotating shaft of the drive motor is connected to the drive gear. The drive gear meshes with the rack 3. The operation of the drive motor causes the drive gear to rotate, which in turn causes the base plate 2 to move along the rack 3. Specifically, the drive gear 4 is located on the lower side of the base plate 2, and the rack 3 is annular, which is adapted to the contour of the tunnel inner wall. The rack 3 is located in the middle of the operating platform 1. The paving mechanism and the compaction mechanism are located on the upper side of the base plate 2. In this embodiment, the drive motor is a servo motor. The specific structure and model are not described here.

[0039] Reference Figure 3 The base plate 2 is provided with mounting seats 5, and the drive teeth 4 are arranged between the mounting seats 5.

[0040] A limiting plate 7 is provided on the rack 3, and a limiting block 8 that cooperates with the limiting plate 7 is provided on the mounting base 5. The movement of the mounting base 5 causes the limiting block 8 to move on the limiting plate 7. The cooperation between the limiting plate 7 and the limiting block 8 prevents the drive tooth 4 from falling off when it moves on the rack 3. Specifically, the limiting plate 7 has a T-shaped cross section, is welded to the rack 3, and is welded to the operating table 1. The limiting plate 7 is annular, and the limiting block 8 is welded to the mounting base 5. In this embodiment, there are two limiting blocks 8, which extend to the two side plates of the limiting plate 7.

The first rotating rod 11 is connected to the crossbar 12, and both ends of the crossbar 12 are connected to the connecting rod 13. The connecting rod 13 is connected to the roller 14. In use, the base plate 2 moves, driving the first fixed rod 9... The movement of rod 9, first telescopic rod 10, first rotating rod 11, crossbar 12, connecting rod 13, and roller 14 allows the waterproof membrane on roller 14 to be laid. The operation of the first telescopic rod 10 causes the first rotating rod 11 to move, which in turn causes the crossbar 12 to move, which in turn causes the connecting rod 13 on the crossbar 12 and roller 14 to move. This adjusts the position of roller 14, ensuring that the waterproof membrane on roller 14 is in stable contact with the inner wall of the tunnel. This ensures that the waterproof membrane on roller 14 is stably attached to the inner wall of the tunnel when roller 14 moves.

The second telescopic rod 16 is connected to the base plate 2, and the moving end of the second telescopic rod 16 is hinged to the second rotating rod 17. The second rotating rod 17 is connected to the compaction roller 18. The movement of the base plate 2 causes the second fixed rod 15, the second telescopic rod 16, the second rotating rod 17, and the compaction roller 18 to move, thereby the compaction roller 18 compacts the waterproof membrane at the unwinding point on the roll 14, thus achieving a smooth contact between the waterproof membrane and the tunnel wall. The operation of the second telescopic rod 16 on the base plate 2 causes the second rotating rod 17 to move, and the movement of the second rotating rod 17 causes the compaction roller 18 to move, thereby adjusting the position of the compaction roller 18 so that the compaction roller 18 precisely fits the waterproof membrane on the tunnel wall.

[0045] Specifically, the rolling roller 18 is located on the lower side of the roll 14 to achieve the rolling operation after the waterproof membrane is unrolled. The second telescopic rod 16 is a hydraulic jack. One end of the second fixed rod 15 is welded to the base plate 2, and the other end of the second fixed rod 15 is hinged to the second rotating rod 17.

The first folding rod 22 is hinged to the second folding rod 23. The second folding rod 23 is hinged to the crossbar 12 or to the rolling roller 18. When the base plate 2 moves to adjust the crossbar 12 and the rolling roller 18, the first folding rod 22 and the second folding rod 23... 23 moves, and the connecting frame 20 connected to the first folding rod 22 moves in the slide groove of the guide seat 19. Through the cooperation of the connecting frame 20 and the slide groove, the two ends of the crossbar 12 and the rolling roller 18 are guided, thereby realizing the stable movement of the waterproof board at the unwinding point on the roll 14 connected to the crossbar 12, and realizing the stable rolling work of the rolling roller 18 on the waterproof board, thus making the finished product of the waterproof board better; and when the crossbar 12 and the rolling roller 18 move, the first folding rod 22 and the second folding rod 23 fold, thereby ensuring the stable connection between the connecting frame 20 and the crossbar 12 and the rolling roller 18.

[0050] A method for using a tunnel folding waterproof membrane laying trolley, comprising the above-mentioned tunnel folding waterproof membrane laying trolley, with the following specific steps:

[0051] Step 1: Preparations before construction;

[0052] Step 2: Move the entire laying trolley into the tunnel;

[0053] Step 3: Install the waterproof membrane onto the laying mechanism;

[0054] Step 4: The driving mechanism moves the base plate 2, which in turn moves the laying mechanism on the base plate 2, and the laying mechanism lays the waterproof membrane on the inner wall of the tunnel.

[0055] Step 5: The base plate 2 moves to activate the compaction mechanism, which then compacts the waterproof membrane.

[0056] Step 6: Welding the waterproof membrane.

[0057] The specific steps of step 1 include:

[0058] 1.1 Check whether the bottom of the operating platform 1 is blocked or obstructed by obstacles on the ground. If there are any obstacles, they should be removed.

[0059] 1.2 Check if there are any improperly placed items on the shelf; if so, place them in a place where they are not likely to fall.

[0060] The working area of ​​operating platform 1 must be on a flat surface, and any exposed hard objects such as rebar ends and anchor bolt heads must be removed. Uneven areas must be repaired by spraying and smoothing.

[0061] Step 2 includes the following specific steps:

[0062] When transporting the operating platform 1 by engineering transport vehicles, the vehicles must slow down and sound the horn as a warning, and safety signal signs for the transport route must be set up in the tunnel to ensure safe transport inside the tunnel.

[0063] Step 3 specifically involves: using a loader to assist in installing the waterproof membrane roll onto the roll 14 of the waterproof membrane laying mechanism, and manually installing and securing both ends of the roll 14 to the connecting rod 13 with bolts.

[0064] Step 4 is as follows: The drive motor works to make the drive gear rotate, and the rotation of the drive gear causes the base plate 2 to move along the rack 3. When the base plate 2 moves, the mounting seat 5 on the base plate 2 moves, causing the limit block 8 to move on the limit plate 7. The cooperation between the limit plate 7 and the limit block 8 prevents the drive gear 4 from falling off when it moves on the rack 3. During the laying operation, it must be ensured that there are no debris on the rack 3 and the drive gear 4, and no personnel or items are allowed to be within the movement path of the base plate 2.

[0065] When the base plate 2 moves, the movement of the base plate 2 drives the first fixed rod 9, the first telescopic rod 10, the first rotating rod 11, the crossbar 12, the connecting rod 13 and the roller 14 to move, so that the waterproof board is laid on the roller 14;

[0066] Furthermore, the operation of the first telescopic rod 10 on the base plate 2 causes the first rotating rod 11 to move, which in turn causes the crossbar 12 to move, which in turn causes the connecting rod 13 and the roller 14 on the crossbar 12 to move, thereby adjusting the position of the roller 14 so that the waterproof membrane on the roller 14 is in stable contact with the inner wall of the tunnel.

[0067] Step 5 specifically involves:

[0068] The movement of the base plate 2 causes the second fixed rod 15, the second telescopic rod 16, the second rotating rod 17 and the rolling roller 18 to move, so that the rolling roller 18 can roll the waterproof board at the unwinding point on the roll 14.

[0069] Furthermore, the operation of the second telescopic rod 16 on the base plate 2 causes the second rotating rod 17 to move, and the movement of the second rotating rod 17 causes the pressure roller 18 to move, thereby adjusting the position of the rolling roller 18 so that the rolling roller 18 is precisely fitted with the waterproof membrane on the inner wall of the tunnel.

[0070] Step 6 specifically involves:

[0071] The waterproof membrane must be laid in accordance with the design requirements. The waterproof membrane should have a certain degree of circumferential slack and needs to be manually fixed and adjusted. After fixing, the waterproof membrane should be welded according to the design requirements.

[0072] When the operating platform 1 is moving, pay attention to the wear of the rollers 25 and promptly remove any obstacles within the range of motion.

[0073] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
