Description

Technical Field

[0001] This utility model relates to the field of pre-embedded channel technology, specifically a pre-embedded channel for large-diameter shield tunnels of high-speed railways. Background Technology

[0002] Pre-embedded channels can significantly improve the structural stability of tunnels. By pre-embedding channels in the tunnel segments, the segments can be more firmly connected to form a whole, thereby enhancing the tunnel's load-bearing capacity. This design not only helps resist external pressure but also provides better protection in natural disasters such as earthquakes. The pre-embedded channel design makes the installation and maintenance of tunnel segments more convenient. During construction, workers can quickly and accurately locate and install tunnel segments through the channels, greatly improving construction efficiency. In addition, if maintenance or equipment replacement is needed during tunnel use, the pre-embedded channels also facilitate these operations. The presence of pre-embedded channels allows the construction team to more precisely control the position and orientation of the tunnel segments, reducing errors and adjustment time during construction. This not only improves construction quality but also reduces construction costs and time costs.

[0003] However, traditional pre-embedded channels have the following disadvantages:

[0004] When installing electrical equipment on traditional pre-embedded channels, it is necessary to remove the pre-embedded channels, run the electrical equipment wires, and then reinstall the pre-embedded channels, which is a very cumbersome operation. Utility Model Content

[0005] The purpose of this utility model is to provide a pre-embedded channel for large-diameter shield tunnels of high-speed railways, so as to solve the problem mentioned in the background art that when installing electrical equipment on the traditional pre-embedded channel, it is necessary to remove the pre-embedded channel, run the electrical equipment wires, and then reinstall the pre-embedded channel, which is a very cumbersome operation.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a pre-embedded channel for a large-diameter shield tunnel of a high-speed railway, comprising a tunnel base, a plurality of cable laying machine housings fixedly installed at the top of the tunnel base, a connecting seat fixedly installed at the top of each of the plurality of cable laying machine housings, a screw threadedly connected to the top of each of the plurality of connecting seats, a winding assembly provided at the top of each of the plurality of screws, cable laying assemblies fixedly installed on both sides of the inner wall of each of the plurality of cable laying machine housings, each of the plurality of cable laying assemblies comprising two telescopic rods and a cable laying platform, the movable ends of the two telescopic rods being fixedly connected to both sides of the bottom end of the cable laying platform, and a plurality of cable laying blocks fixedly installed at the top of the cable laying platform.

[0007] Preferably, two symmetrically arranged support springs are fixedly installed at the bottom of the wiring platform.

After the wire passes through the wiring groove, the wire squeezes the wiring block, the wiring block squeezes the wiring platform, the wiring platform squeezes the telescopic rod, and the telescopic rod performs telescopic movement. The support springs are elastic, and the elastic deformation of the support springs buffers the squeezing force. Therefore, the wiring block guides the wire from both sides.

[0008] Preferably, each of the cable trays has a cable tray groove at its top, and two opposite cable trays cooperate to perform cable routing operations on the electrical equipment wires.

[0009] Preferably, each of the winding assemblies includes a magnetic rod and a limiting plate. The top end of the magnetic rod is fixedly connected to the bottom end of the limiting plate. The surface of the magnetic rod is provided with a plurality of dividing plates, through which the wires of the electrical equipment are arranged in an orderly manner.

[0010] Preferably, the surface of the magnetic rod is slidably connected with a plurality of movable blocks, and the middle part of the plurality of movable blocks is fixedly connected to a plurality of dividing plates respectively.

[0011] Preferably, magnetic strips are fixedly installed on both sides of the inner wall of several movable blocks, and the magnetic strips are magnetically connected to the magnetic rod. The user slides the movable block to adjust the position of the dividing plate relative to the magnetic rod, and then the user fixes the movable block to the magnetic rod by the magnetic attraction of the magnetic strip itself, thus completing the fixation of the movable block.

[0012] Preferably, a locking block is fixedly installed at the bottom end of the magnetic rod, and a locking groove is opened at the top end of the screw. The locking block and the locking groove are correspondingly set, and the magnetic rod is locked into the locking groove through the locking block, thus completing the assembly of the winding assembly and the screw.

[0013] Compared with the prior art, the beneficial effects of this utility model are: by setting up a wiring assembly and a winding assembly, the electrical equipment wires on the high-speed railway are arranged in an orderly manner through the wiring grooves on the two wiring blocks. Excess wires are wound in an orderly manner around the grooves divided by the dividing plate, which replaces the traditional operation of disassembling the tunnel pre-embedded groove, improves the installation and construction efficiency of the electromechanical system, causes virtually no damage to the tunnel structure, and extends the service life of the structure.

Several cable laying blocks 64 are fixedly installed on the top of the cable laying platform 63.

[0021] Two symmetrically arranged support springs 62 are fixedly installed at the bottom of the cable tray 63. One end of the two support springs 62 and the fixed end of the two telescopic rods 61 are fixedly connected to the side of the cable tray housing 2 facing each other.

[0025] Several movable blocks 53 have magnetic strips 55 fixedly installed on both sides of their inner walls. The magnetic strips 55 are magnetically connected to the magnetic rod 52. The user slides the movable block 53 to adjust the position of the dividing plate 54 relative to the magnetic rod 52. Then, the user fixes the movable block 53 to the magnetic rod 52 by the magnetic attraction of the magnetic strips 55 themselves.

[0026] A locking block 56 is fixedly installed at the bottom of the magnetic rod 52, and a slot 7 is opened at the top of the screw 4. The locking block 56 and the slot 7 are set in correspondence.
