Large-diameter shield tunnel full-prefabricated fast-assembly internal structure and construction method
The invention provides a full-prefabricated fast-assembly internal structure of a large-diameter shield tunnel and a construction method. The internal structure comprises a prefabricated middle box culvert, prefabricated side box culverts and connecting steel plates. The middle box culvert is arranged in the middle of the large-diameter shield tunnel, the middle box culvert is of a square-like frame structure, the side box culverts are of C-shaped opening structures, and openings of the two side box culverts face oppositely and are formed in the two transverse end side faces of the middle box culvert correspondingly; the longitudinal width of the middle box culvert and the longitudinal width of the side box culverts are matched with the ring width of a tunnel lining segment. First angle steel is pre-embedded in the tops of the two transverse ends of the middle box culvert, second angle steel is pre-embedded in the top connecting ends of the side box culverts, and the connecting steel plates are welded to the tops of the first angle steel and the second angle steel. Bottom connecting ends of the side box culverts are in mortise and tenon connection with the bottoms of transverse end side surfaces of the middle box culverts; according to the technical scheme, the precision and efficiency of prefabrication and assembly are improved, and higher economical efficiency is achieved.
本发明提供了一种大直径盾构隧道全预制快速装配内部结构及施工方法，所述内部结构包括预制的中部箱涵、预制的边箱涵和连接钢板；中部箱涵设置于大直径盾构隧道中部，中部箱涵为类口字型框架结构，边箱涵为C型开口结构，两个边箱涵开口朝向相对且分别设置于中部箱涵的两个横向端侧面；中部箱涵和边箱涵的纵向宽度和隧道衬砌管片的环宽相适应；中部箱涵的两个横向端顶部分别预先埋设有第一角钢，边箱涵的顶部连接端预先埋设有第二角钢，连接钢板焊接于第一角钢和第二角钢的顶部；边箱涵的底部连接端卯榫连接于中部箱涵的横向端侧面底部；通过上述技术方案，本发明提高了预制拼装的精度及效率，具有更高的经济性。
