Description

Technical Field

[0001] This invention relates to the field of tunnel waterproofing construction technology, and in particular to a waterproofing construction method based on an integrated tunnel arch trestle. Background Technology

[0002] Railway tunnels are passageways specifically designed for train transport. When railways traverse mountainous areas, due to limited traction capacity and maximum gradient requirements (less than 24%), overcoming elevation obstacles is necessary. Excavating tunnels to cross mountains is a reasonable choice, as it shortens the track, reduces gradient, improves operating conditions, and increases traction capacity. Based on their location, they can be divided into three main categories: mountain tunnels, which pass under mountains or hills to shorten distances and avoid steep gradients; underwater tunnels, which pass under rivers or straits to cross waterways or straits; and urban tunnels, which pass under cities to accommodate railways passing through large cities. Waterproofing materials are required in railway tunnels, necessitating the use of railway tunnel waterproofing material laying devices.

[0003] The existing railway tunnel waterproofing material laying devices have the following defects:

[0004] 1. Existing railway tunnel waterproofing material laying devices are generally only used to transport waterproofing materials to designated locations, and manual laying is still required, resulting in low work efficiency, harsh construction environment, and safety risks.

[0005] 2. Existing railway tunnel waterproofing material laying devices occupy most of the tunnel area, preventing other construction vehicles from passing and affecting overall construction efficiency. Summary of the Invention

[0006] In view of this, the present invention provides a waterproof paving construction method based on an integrated tunnel arch trestle bridge to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A waterproof paving construction method based on an integrated tunnel arch trestle bridge includes the following steps:

[0009] S1: Move the trestle to the tunnel construction position. The arched track is located at the starting point of the construction section. Both transport trolleys are located at the starting and ending ends of the arched track. First, the clamping arm clamps the waterproof material rolled on the mandrel and presses the waterproof material onto the tunnel lining. Then, the welding arm welds the waterproof material onto the tunnel lining. After welding is completed, the active walking unit drives the arched track to move along the walking rails to the end of the construction section and repeats the above waterproof material laying process until the waterproof material laying of the tunnel lining at the same height of the entire construction section is completed.

[0010] S2: At this point, the arched track is at the end of the construction section. Both transport trolleys move towards the center of the arched track to continue laying waterproof material and ensure that it overlaps with the waterproof material laid in S1. After welding is completed, the active walking unit drives the arched track to move along the walking rail towards the starting point of the construction section and repeats the above waterproof material laying process to complete the waterproof material laying of the tunnel lining at the same height in the entire construction section.

[0011] S3: Repeat S1 and S2. After the waterproofing material is laid on the tunnel lining of the entire construction section, the arched track moves to the next construction section to lay the waterproofing material on the tunnel lining, ensuring that it overlaps longitudinally with the waterproofing material laid in the previous construction section. After the waterproofing material is laid on the tunnel lining at the construction position of the trestle, the trestle moves to the next construction position to lay the waterproofing material until the waterproofing material is laid on the entire tunnel lining.

[0012] Furthermore, when there is insufficient working space to lay the waterproof material to the center of the tunnel lining, one side of the transport trolley moves away from the center of the arched track to leave enough working space, while the other side of the transport trolley moves closer to the center of the arched track and completes the laying of the waterproof material at the center of the tunnel lining.

[0013] A waterproof paving construction method based on an integrated tunnel arch trestle bridge includes the following steps:

[0014] S1: Move the trestle to the tunnel construction location. The arched track is located at the starting point of the construction location. A transport trolley is located at the starting end of the arched track. First, the clamping arm clamps the waterproof material rolled on the mandrel and presses the waterproof material onto the tunnel lining. Then, the welding arm welds the waterproof material onto the tunnel lining. After welding is completed, the transport trolley moves to the end of the arched track and repeats the above waterproof material laying process until the waterproof material laying of the tunnel lining in the same longitudinal direction of the entire construction location is completed.

[0015] S2: At this time, the transport trolley is located at the end of the arched track. The active walking unit drives the arched track to move along the walking rails to the end of the construction position, continue to lay the waterproof material, and ensure that it overlaps longitudinally with the waterproof material laid in S1. After the welding is completed, the transport trolley moves to the beginning of the arched track and repeats the above waterproof material laying process until the waterproof material laying of the tunnel lining in the same longitudinal direction of the entire construction position is completed.

[0016] S3: Repeat S1 and S2 until the waterproofing material for the tunnel lining at the construction location of the trestle is completed. Then move the trestle to the next construction location to lay the waterproofing material until the waterproofing material for the entire tunnel lining is completed.

[0017] The beneficial effects of this invention are as follows:

[0018] The arched laying trolley in this invention is designed to ensure clearance for vehicles to pass through and to allow other construction vehicles to pass through the tunnel. By laying waterproof materials using the trolley, there is no need for manual labor in the harsh environment of the tunnel, eliminating safety risks and reducing labor costs.

The inner side of the arched paving trolley 1 is used to accommodate the passage of other construction vehicles, and a transport trolley 2 is slidably connected to the outer side of the arched paving trolley 1. The transport trolley 2 is used to lay waterproof material on the tunnel lining 4, which is located outside the tunnel lining 3. In this embodiment, the arched paving trolley 1 is set to ensure clearance for vehicles to pass through and to allow other construction vehicles to pass through the tunnel. By laying waterproof material through the transport trolley 2, there is no need for manual labor in the harsh environment of the tunnel, eliminating safety risks and reducing labor costs.

[0041] The arched laying trolley 1 includes an arched track 11, with both ends of the arched track 11 slidably connected to the trestle 5 via a traveling mechanism.

[0042] The walking mechanism includes a walking beam 12, which is fixedly installed at both ends of the arched track 11. An active walking unit 13 is fixedly installed at one end of the bottom surface of the walking beam 12, and a passive walking unit 14 is fixedly installed at the other end. Walking rails 51 are provided on both sides of the top surface of the trestle 5. The active walking unit 13 and the passive walking unit 14 are both adapted to the walking rails 51.

[0043] The transport trolley includes a support frame 21 and a wheel set 20 adapted to the arched track 11. The support frame 21 is slidably connected to the arched track 11 through the wheel set 20. The support frame 21 has an installation groove 22 on the side away from the arched track 11. A storage unit is provided on one side of the installation groove 22 and an installation unit is provided on the other side.

[0044] The storage unit includes a mandrel 24, which is mounted on one side of the mounting groove 22 via two fixing brackets 23. The mandrel 24 is rotatably connected between the two fixing brackets 23, and a waterproof material 25 is rolled onto the mandrel 24. In this embodiment, the mandrel 24 is perpendicular to the longitudinal direction of the tunnel.

[0045] The installation unit includes a first rotating base 26 and a second rotating base 27, which are sequentially fixedly disposed on the side of the mounting groove 22 away from the mandrel 24. A clamping arm 28 is fixedly connected to the driving end of the first rotating base 26 for clamping the waterproof material 25. A welding arm 29 is fixedly connected to the driving end of the second rotating base 27 for welding the waterproof material 25. In this embodiment, both the clamping arm 28 and the welding arm 29 can rotate 360°. The welding arm 29 welds the waterproof material 25 to the tunnel lining 4 using a hot-melt pad and inspects the quality of the welding between the waterproof material 25 and the hot-melt pad.

[0046] See appendix Figure 7-8 The transport trolley on the arched laying trolley 1 can be disassembled, and multiple detachable working platforms can be evenly installed on the arched laying trolley 1. Workers can stand on the detachable working platforms to complete the work of tying steel bars or the maintenance of the tunnel.

[0047] See appendix Figure 9-10 A waterproof paving construction method based on an integrated tunnel arch trestle bridge includes the following steps:

[0048] S1: Move the trestle 5 to the tunnel construction position. The arched track 11 is located at the starting point of the construction section. Both transport trolleys 2 are located at the starting and ending ends of the arched track 11. First, the clamping arm 28 clamps the waterproof material 25 rolled on the mandrel 24 and presses the waterproof material 25 onto the tunnel lining 4. Then, the welding arm 29 welds the waterproof material 25 onto the tunnel lining 4. After welding is completed, the active walking unit 13 drives the arched track 11 to move along the walking rail 51 to the end of the construction section and repeats the above waterproof material 25 laying process until the waterproof material 25 is laid on the tunnel lining 4 at the same height of the entire construction section. In this embodiment, the construction section is 12m long, the arched track 11 is 4m long along the tunnel depth direction, and the working range of the welding arm 29 and the clamping arm 28 is 4m. The arched track 11 needs to be moved at least 3 times from the starting point to the end point of the construction section. It can also be moved gradually during the work process as needed.

[0049] S2: At this time, the arched track 11 is located at the end of the construction section. Both transport trolleys 2 move towards the center of the arched track 11 to continue laying the waterproof material 25, and ensure that it overlaps with the waterproof material 25 laid in S1. In this embodiment, the waterproof material 25 is 4m wide and the circumferential overlap length is 125mm. After the welding is completed, the active walking unit 13 drives the arched track 11 to move along the walking rail 51 towards the starting point of the construction section, and repeats the above waterproof material 25 laying process to complete the laying of waterproof material 25 on the tunnel lining 4 at the same height in the entire construction section.

[0050] S3: Repeat S1 and S2. After the waterproof material 25 of the tunnel lining 4 is laid in the entire construction section, the arched track 11 moves to the next construction section to lay the waterproof material 25 of the tunnel lining 4, ensuring that it overlaps longitudinally with the waterproof material 25 laid in the previous construction section. After the waterproof material 25 of the tunnel lining 4 at the construction position of the trestle 5 is laid, the trestle 5 moves to the next construction position to lay the waterproof material 25 until the waterproof material 25 of the entire tunnel lining 4 is laid.

[0051] When there is insufficient working space to lay the waterproof material 25 to the center of the tunnel lining 4, one side of the transport trolley 2 moves away from the center of the arched track 11 to leave enough working space, while the other side of the transport trolley 2 moves closer to the center of the arched track 11 and completes the laying of the waterproof material 25 at the center of the tunnel lining 4.

[0062] S1: Move the trestle 5 to the tunnel construction position. The arched track 11 is located at the starting point of the construction position. A transport trolley 2 is located at the starting end of the arched track 11. First, the clamping arm 28 clamps the waterproof material 25 rolled on the mandrel 24 and presses the waterproof material 25 onto the tunnel lining 4. Then, the welding arm 29 welds the waterproof material 25 onto the tunnel lining 4. After the welding is completed, the transport trolley 2 moves to the end of the arched track 11 and repeats the above waterproof material 25 laying process until the waterproof material 25 laying of the tunnel lining 4 in the same longitudinal direction of the entire construction position is completed.

[0063] S2: At this time, the transport trolley 2 is located at the end of the arched track 11. The active walking unit 13 drives the arched track 11 to move along the walking rail 51 to the end of the construction position, and continues to lay the waterproof material 25, ensuring that it overlaps longitudinally with the waterproof material 25 laid in S1. After the welding is completed, the transport trolley 2 moves to the beginning of the arched track 11 and repeats the above waterproof material 25 laying process until the waterproof material 25 laying of the tunnel lining 4 in the same longitudinal direction of the entire construction position is completed.

[0064] S3: Repeat S1 and S2 until the waterproofing material 25 of the tunnel lining 4 at the construction location of the trestle 5 is laid.

[0065] In this embodiment, the waterproof material 25 includes geotextile and waterproof board. The geotextile is laid first, and then the waterproof board is laid.

[0066] During the installation of waterproof materials, this invention ensures sufficient clearance for other construction vehicles in the tunnel to pass through. The construction process is fully automated, allowing operators to control the process on-site via buttons or remotely. This improves the quality of tunnel waterproofing, eliminates the need for manual labor in the harsh tunnel environment, eliminates safety risks, reduces labor costs, and significantly accelerates the construction progress.
