Full-prefabricated track structure and method for shield tunnel assembly integration
The invention provides a full-prefabricated track structure and method for shield tunnel assembly integration, relates to the technical field of tunnel track bed construction, and aims at solving the problem that the concrete mixing, transporting and cast-in-place speed is low in the cast-in-place construction process of a traditional cast-in-place track bed foundation. Fixed connection of the prefabricated roadbed slab, the prefabricated roadbed foundation and the shield tunnel prefabricated duct piece is achieved on site through matching of the connecting pieces and the channels, the hole grooves reserved in the connecting piece matching structure serve as positioning points of matching of the prefabricated roadbed slab and the prefabricated roadbed foundation, the assembly precision is improved, and stability of the connecting pieces can be kept through the locking pieces; a stable and reliable structure is cooperatively achieved, and looseness of connecting pieces is avoided.
本发明提供一种用于盾构隧道装配一体化的全预制轨道结构及方法，涉及隧道道床施工技术领域，针对传统现浇道床基础现浇施工过程中混凝土拌制、运输、现场浇筑速度慢的问题，将道床基础采用预制生产，在现场通过连接件配合槽道实现预制道床板、预制道床基础和盾构隧道预制管片的固连，利用连接件配合结构预留的孔槽作为预制道床板配合预制道床基础的定位点，提高装配精度并能够利用锁定件保持连接件的稳定，协同实现稳定可靠结构避免连接件的松动。
