Description

Technical Field

[0001] This application relates to the technical field of personnel-machine separation platform layout in the tunnel boring machine track area, and in particular to a construction structure for personnel-machine separation platform layout in a limited site. Background Technology

[0002] The human-machine separation platform in the shield tunnel shaft track area needs to be connected to the tunnel walkway. Currently, most of them use a platform-less design. The bottom plate of the shield tunnel shaft track area is accessed by a staircase, and the structural bottom plate is directly used as a pedestrian passage and connected to the tunnel walkway. The pedestrian passage and the track area are separated by guardrails, and the left and right lines are connected through the other end of the track area.

[0003] However, the platformless design requires workers on the left and right lines to walk a long distance when changing jobs, which affects work efficiency and needs to be improved. Utility Model Content

[0004] The purpose of this application is to provide a construction structure for a human-machine separation platform in a limited site, so as to improve the problem of long walking distance in the tunnel boring machine track area.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A construction structure for a pedestrian walkway platform with limited space for separating pedestrians and machines includes a pedestrian walkway platform comprising a public platform, a left-line platform, and a right-line platform. The structure is characterized by: a pedestrian overpass connecting to a track-crossing area being provided between the left-line platform and the right-line platform; one end of the overpass connecting to the left-line platform and the other end connecting to the right-line platform; mounting plates are provided at the bottom of both ends of the overpass, and rollers are provided in the middle of the mounting plates.

[0007] By adopting the above technical solution, after arriving at the public platform, workers can directly enter the left or right platform via the pedestrian overpass in the cross-track area to carry out construction work. At the same time, depending on different construction conditions, the pedestrian overpass in the cross-track area can be moved to the corresponding construction area, so that workers can move between the left and right platforms without obstacles in any construction section.

[0008] Furthermore, a skybridge track is provided on the side of the left and right line platforms that are close to each other, and the rollers roll within the skybridge track.

[0009] By adopting the above technical solution, the pedestrian overpass in the cross-track area can be moved to the location that best meets the needs of the workers, with the help of external forces.

[0010] Furthermore, the upper surface of the overpass track is provided with positioning holes, and anti-movement bolts for fixing the pedestrian overpass in the track crossing area are inserted into the positioning holes.

[0011] By adopting the above technical solution, after moving the pedestrian overpass in the cross-track area to the area between the two positioning holes, the anti-movement bolt is inserted into the positioning hole to fix the pedestrian overpass in the cross-track area and prevent it from moving during use.

[0012] Furthermore, the bottom of the pedestrian overpass in the cross-track area is provided with a first overpass leg, and a second overpass leg is sleeved at the lower end of the first overpass leg. Both the first overpass leg and the second overpass leg are provided with telescopic holes, and a fixing device is inserted into the telescopic holes on the first overpass leg and the second overpass leg.

[0013] By adopting the above technical solution, when the ground inside the tunnel is uneven, the length of the second bridge support leg extending beyond the first bridge support leg can be adjusted by pulling out the fixing device, and then the fixing device can be inserted into the expansion hole where the first and second bridge supports overlap. This ensures that when the pedestrian overpass in the cross-track area moves to different depths of the tunnel ground, both the first and second bridge supports meet the support requirements.

[0014] Furthermore, detachable guardrails are provided on the sides of the left and right line platforms that are close to each other; platform guardrails are provided on the sides of the left and right line platforms that are far from each other and on both sides of the public platform; and pedestrian overpass guardrails are provided on both sides of the overpass.

[0015] By adopting the above technical solution, when moving the pedestrian overpass across the track area, the detachable guardrails of the section of the pedestrian overpass that the overpass passes through can be removed first. After the pedestrian overpass stops moving, the removed parts can be reinstalled. The platform guardrails ensure the safety of the workers, and the pedestrian overpass guardrails can also serve as handles when moving the pedestrian overpass across the track area, while ensuring the safety of the workers.

[0016] Furthermore, platform legs are provided at the bottom of the left and right line platforms.

[0017] By adopting the above technical solution, the platform outriggers support the left and right platforms, ensuring the stability of the left and right platforms when workers are moving on the platform.

[0018] Furthermore, a staircase leading down to the well is provided at the end of the public platform away from the right-line platform, and guardrails are provided on both sides of the staircase.

[0019] By adopting the above technical solution, workers can travel between the ground and the public platform via the downhole stairs, and the guardrails on the downhole stairs also serve a protective function, ensuring the safety of the workers.

[0020] Furthermore, the bottom of the public platform is provided with public platform support legs for support.

[0021] By adopting the above technical solution, the support legs of the public platform play a supporting role, enabling workers to carry out construction work on the public platform.

[0022] Furthermore, the left platform and the right platform are respectively provided with staircases connecting to the bottom of the tunnel, and the staircases are provided with guardrails on both sides.

[0023] By adopting the above technical solution, workers can access the storage space reserved below the left and right platforms via the stairs on the platform; the stair railings can ensure the safety of workers.

[0024] Furthermore, the left-line platform and the right-line platform are respectively connected and installed with left-line tunnel walkway slabs and right-line tunnel walkway slabs on the side away from the public platform.

[0025] By adopting the above technical solution, the walkway panels of the left and right tunnels lead to the depths of the tunnel at the ends of the left and right platforms, and can serve as temporary work panels during the extension and construction of the left and right platforms.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. The pedestrian overpass at both ends is equipped with rollers at the bottom, allowing it to roll within the overpass tracks on opposite sides of the left and right track platforms. After removing the detachable guardrails, workers can directly push the pedestrian overpass and secure it with anti-movement bolts. The operation is convenient, and workers can adjust the position of the pedestrian overpass according to actual work needs, enabling flexible cross-line construction operations and improving work efficiency.

[0028] 2. The first and second bridge legs at the bottom of the pedestrian overpass in the cross-railway area can adapt to tunnel ground at different heights: After the pedestrian overpass in the cross-railway area is moved, adjust the height of the second bridge leg to the appropriate position, and insert the fixing device into the overlapping telescopic hole of the first and second bridge legs to ensure that the first and second bridge legs meet the support requirements.

[0029] 3. A certain clearance height is designed under the left and right platforms, which can be used to store tools and materials needed for construction. Workers can reach the storage space under the left or right platform by going up and down the stairs of the platform. The stairs of the platform are also equipped with guardrails to ensure the safety of workers and make full use of the existing space. Attached Figure Description
