Embodiment Construction
[0042] Combine below Figure 1 to Figure 16 , the present invention is further described:
[0043] Such as Figure 1 to Figure 3 As shown, the embedded sleeve 1 includes a cylinder body 11, an anchor leg 12 and a base 13, one end of the anchor leg 12 is connected to the bottom of the cylinder body 11, the other end of the anchor leg 12 is connected to the base 13, and one end of the T-bolt 14 is inserted into the cylinder In the connection hole 18 of the body 11, the positioning is locked by a limit locking mechanism.
[0044] Such as Figure 4 to Figure 8 As shown, the connecting hole 18 of the cylinder 11 has an irregular structure in the axial direction; its lower end along the circumferential direction or the inner wall direction of the cylinder is successively the first automatic locking limit block 111, the second rotatable area 114, the second The automatic locking limit block 112 and the first rotatable area 113, the two sides of the end of the T-bolt 14 are respect...

The invention relates to a rail traffic shield tunnel non-destructive quick mounting system. In the manufacturing process of a rail traffic shield tunnel, multiple pre-buried sleeves (1) are pre-buried in the circumferential direction and the axial direction of an annular tunnel and then are fixedly poured into the inner wall of the rail traffic shield tunnel through cement, T-shaped bolts (14) are exposed and are connected with the insides of the pre-buried sleeves (1), and through the cooperation of the pre-buried sleeves (1), the T-shaped bolts (14) and the bolts (17), one or more of an APantenna support, a cable support (4), a temperature sensing optical fiber support, an illuminating lamp (9), a leakage coaxial cable support, a distribution box support, an evacuating platform armrest, a water pipe support (2) and an emergency platform support (8) in the rail traffic shield tunnel are fixed. The rail traffic shield tunnel non-destructive quick mounting system has the advantages ofbeing simple in construction, shortening the work period, being flexible to install, reducing construction environment pollution and being firm and reliable to connect, low in cost and the like.
Description
technical field [0001] The invention relates to a connection and installation device in the technical field of civil engineering, in particular to a damage-free rapid installation system for a rail transit shield tunnel. Background technique [0002] At present, the installation of most subway tunnel cables, pipelines and equipment mainly adopts the anchor bolt method, that is, the drilling method is used to implant mechanical or chemical anchor bolts into the segment, and the mechanical expansion or the bonding force of chemical glue is used to fix the pipeline support. This method has great damage to the segment structure, long construction period, great construction environmental pollution and high maintenance and replacement costs. In order to solve the defects of the traditional anchoring method, the prefabricated segment can be used to pre-embed the anchor connector for the fixed installation of equipment and pipelines. As a result, the non-damage installation system h...
