Subway channel assembling structure, assembling method and sleeve embedding method

Abstract

The invention discloses a subway channel assembling structure and method and a sleeve embedding method. The subway channel assembling structure comprises a pipe sheet, a plurality of sleeves, sliding grooves, a plurality of bolt rods and a plurality of locking nuts, wherein internal threads are tapped on the inner walls of the sleeves, one ends of the multiple sleeves are embedded in the pipe sheet at intervals along a straight line, and sleeve openings of the sleeves communicate with the outer part of the pipe sheet; the bottom of each sliding groove is provided with a plurality of first reserved holes arranged at intervals, the first reserved holes of the sliding grooves can correspond to the positions of sleeve openings of the sleeves embedded in the pipe sheet, one end of each bolt rod penetrates through the first reserved holes of the corresponding sliding groove and is in threaded connection with the internal threads of the corresponding sleeve, and the other end of each bolt rod is in locking connection with the corresponding locking nut, so that the sliding grooves can be locked to the pipe sheet. The subway channel assembling structure has the advantages of being simple in structure, high in installation speed, capable of avoiding vibration relaxation and capable of saving cost.

Description

technical field [0001] The invention relates to the technical field of tunnel construction, in particular to an assembly structure of a subway channel, an assembly method and a sleeve embedding method. Background technique [0002] At present, the lining segments of subway tunnels mainly use external channels or pre-embedded channels. The external channel is fixed by on-site anchoring. This method needs to drill holes in the existing segment structure, and then connect the external channel through the bolt rod. The connection process is diverse, mainly welding. The pre-embedded channel is directly embedded in the concrete segment of the tunnel, without borrowing any drilling bolts, and does not need to be fixed by welding. The channel is pre-embedded through the mold directly when pouring the segment. In the segment, after the segment is installed, take the channel at the corresponding position to install catenary and other equipment. [0003] For the existing chemical anc...

AI Technical Summary

Problems solved by technology

[0003] For the existing chemical anchor bolt drilling method, the structural steel bars of the segment may be touched during the process, which may cause damage to the segment itself, affecting the safety and durability of the segment, and the drilling time is long and the construction The noise is extremely high, which not only affects the health of workers, but also the construction efficiency is low, and the construction quality cannot be guaranteed. In addition, the catenary is subjected to dynamic load for a long time, which makes the channel connecting the catenary easy to loose due to vibration and the connection falls off; For the embedded channel, compared with the external channel fixed by chemical anchor bolts, it can reduce the construction time and improve the stability and quality of the segment structure, but the biggest problem is that the embedded channel needs to be installed in the whole pipe. The pre-embedded channel within the range of the segment, and the cost of the channel itself is relatively expensive, and it is easy to be corroded by moisture along with the concrete curing of the segment, and the overall engineering cost is also high, so it is inevitable to waste the pre-embedded channel
