Pipe jacking method double-barrel prefabricated pipe gallery
The pipe jacking method double-barrel prefabricated pipe gallery comprises a plurality of pipe jacking outer barrels connected in series along the axis and a plurality of prefabricated inner barrel pipe galleries connected in series along the axis, each pipe jacking outer barrel is of a barrel structure with the outer side straight and the inner side fluctuating, and each prefabricated inner barrel pipe gallery is of a barrel structure with the inner side straight and the outer side fluctuating. Each prefabricated inner barrel pipe gallery is wrapped by the two adjacent pipe jacking outer barrels, the length of the prefabricated inner barrel pipe gallery is equal to that of the pipe jacking outer barrels, the two ends of the prefabricated inner barrel pipe gallery are completely flush with the vertical faces where the center lines of the straight sections of the two outer barrels are located respectively, and in the pipe jacking method construction process, the pipe jacking outer barrels are main force transmission components; according to the pipe jacking construction type prefabricated pipe gallery, the quality is guaranteed, meanwhile, the construction speed of the pipe jacking construction type prefabricated pipe gallery is reduced, and the anti-leakage performance of the prefabricated pipe gallery is further improved.
本发明公开了一种顶管法双筒预制管廊，其包括多个沿轴线串联的顶管外筒和多个沿轴线串联的预制内筒管廊，所述顶管外筒为外侧平直内侧起伏的筒体结构，所述预制内筒管廊为内侧平直外侧起伏的筒体结构，每个所述预制内筒管廊由两个相邻的所述顶管外筒包覆，所述预制内筒管廊的长度等于所述顶管外筒，所述预制内筒管廊的两端分别与两个所述外筒中平直段的中线所处立面完全平齐，在顶管法施工过程中，顶管外筒为主传力构件，再被顶推向前时带动内部包覆的同轴的预制内筒管廊，本发明除了在保证质量的同时压缩了顶管施工式的预制管廊施工速度，还提高了预制管廊的抗渗漏性能。
