Description

Technical Field

[0001] The utility model belongs to the technical field of rail transportation, and in particular relates to a signal equipment installation device and integrated signal equipment. Background Art

[0002] Currently, the signal equipment that needs to be installed on the shield tunnel wall includes signal machines, signal leaky cables and signal boxes. In the traditional installation method in the tunnel, the signal machines and signal boxes are fixed using post-planted anchor bolt technology. Post-planted anchor bolt technology is to use an electric hammer or a drilling machine to drill holes on the pipe segments, then install expansion bolts or chemical bolts, and finally connect pipelines and brackets and other structural parts. The following problems exist in construction and maintenance: 1. Intensive drilling operations are carried out on the pipe segments, which damages the pipe segment structure and causes structural water leakage; in addition, the lifespan of chemical anchor bolts and expansion bolts is limited, and secondary drilling is required at that time, which seriously reduces the lifespan of the main structure; 2. Positioning and drilling on the pipe segments one by one, the concrete pipe segments are densely reinforced, and the frequency of drilling encountering steel bars is high. It is common to drill multiple holes in one hole, which has low work efficiency and difficult to ensure installation quality; 3. Noise, vibration, a large amount of dust and other pollution are generated during the drilling process, resulting in poor working conditions and affecting the health of on-site construction personnel; 4. After years of use, the tunnel pipe segments have serious holes and cracks that leak and are difficult to repair. When adding or replacing equipment in the later stage, drilling operations are still required, which makes maintenance difficult.

[0003] To address these issues, tunnel pre-embedding technology has emerged. This involves pre-reserving installation foundations (such as chutes, lugs, and sleeves) on the tunnel wall. Equipment is secured to this foundation using bolts and other fastening methods, thus avoiding the need for drilling holes in the tunnel wall. This technology represents the future development direction of subway shield tunnel construction. Compared to traditional anchor bolt installation methods, this method offers the following advantages: 1. Factory-based processing and pre-embedding facilitate enhanced project quality control; 2. Avoiding drilling damage to the structure improves its durability and service life; 3. Pipeline installation is simple and efficient; 4. Pipeline equipment installation and construction are pollution-free, creating a favorable working environment; 5. All systems can be integrated onto the pre-reserved installation foundation, facilitating maintenance and replacement of tunnel equipment and pipelines during operation.

[0004] Among tunnel pre-embedded technologies, pre-embedded sleeve technology is an emerging pre-embedded technology. Compared with other pre-embedded technologies, it has the advantages of being quicker and more convenient to install in the later stage, high construction efficiency, and saving construction period. The sleeve can be pre-embedded according to the equipment installation requirements, eliminating the expensive external grooves and saving costs. It has gradually surpassed pre-embedded slides, hanging ears and other technologies, and has become the new mainstream pre-embedded technology for the installation and construction of urban rail transit shield tunnel equipment.

[0005] Typically, signal control cables are routed through a terminal cable box and then connected to the signal via a pigtail cable. In subway shield tunnels, the signal and axle counter are often installed side-by-side. For these two reasons, the axle counter box, terminal cable box, and other equipment must also be installed near the signal. The key difference between the pre-buried sleeve solution and the anchor bolt solution is that it cannot be installed by drilling holes in any arbitrary location in the tunnel wall. Therefore, signal equipment is traditionally installed in a decentralized manner, with the signal, axle counter box, and terminal cable box each mounted on their own bracket. This complex construction and the multiple bracket types make it difficult for construction companies to stock up on these brackets. Utility Model Content
