scratch into formula quick-operation joint is including pre-buried T type spare and the C type spare at two section of jurisdiction body circumferential weld lateral walls of mutual concatenation, when the vertical concatenation of section of jurisdiction body, T type spare slidable mounting is in C type spare.
Based on current pin-connected panel section of jurisdiction structure, carry out the structure pertinence design of vacuum magnetic suspension operating mode, when guaranteeing structure assembly precision and intensity, additional strengthening's sealing performance to improve vacuum magnetic suspension tunnel structure's reliability.
Furthermore, the grouting holes and the caulking joints of the inner arc surface of the duct piece body are sealed by MS sealant.
Further, the spraying of section of jurisdiction body intrados has the waterproof sealing coating of 2mm thick waterproof sealing coating skin has laid the waterproofing membrane of 2mm thick.
Furthermore, the splicing part of the waterproof coiled material is lapped and welded.
The sealing coating has to have good compatibility with the waterproof coiled material while ensuring the strength so as to realize large-area waterproof sealing of the intrados of the duct piece.
Furthermore, composite fiber concrete with the thickness of 20cm is poured on the outer side of the waterproof roll.
Composite fibers are adopted to replace reinforcing steel bars in the concrete, so that the structural strength is guaranteed, and the structural weight is reduced.
Further, waterproof sealing coating is polyurea coating, just waterproofing membrane is TPO polyolefin waterproofing membrane.
The fastening of adjacent segments is completed by adopting the plug-in quick joint and the slide-in quick joint, the structure is firm and easy to install, the leakage channel of the structure can be reduced by a bolt-free structure, meanwhile, the quick joint is beneficial to quick construction, labor and time cost are saved, the assembling precision and quality of the tunnel can be effectively improved, and the occurrence probability of the leakage channel is reduced;
through adopting composite fiber concrete to replace the reinforcing bar at the innermost secondary lining of section of jurisdiction structure tunnel, can reduce structure weight in the time of guaranteeing structural strength.
