Prefabricated structure of urban open cut tunnel and construction method
The invention relates to the technical field of underground structure engineering, in particular to a prefabricated structure of an urban open cut tunnel and a construction method. The prefabricated structure of the urban open-cut tunnel comprises prefabricated pile walls, prefabricated rails and prefabricated units, pile wall connecting grooves extending in the front-back direction are formed in the opposite wall faces of the prefabricated pile walls, and the prefabricated rails are poured on the ground; the prefabricated unit comprises two end prefabricated units and at least two assembly prefabricated units, and each of the end prefabricated units and the assembly prefabricated units comprises a base, side walls integrally poured at the left end and the right end of the base, a top wall integrally poured at the tops of the side walls and a middle partition wall integrally poured between the top wall and the base. A base connecting groove and a base grouting pipe which are in sliding fit with the prefabricated track are arranged on the base; a side wall connecting block, a side wall grouting pipe and a gap grouting pipe which are in sliding fit with the prefabricated pile wall are arranged on the side wall; the adjacent prefabricated units are matched in an inserted mode and provided with inserted grouting pipes. The prefabricated structure and cast-in-place are combined, and the construction efficiency is improved.
本发明地下结构工程技术领域，尤其涉及一种城市明挖隧道的预制结构及施工方法。城市明挖隧道的预制结构包括预制桩墙、预制轨道和预制单元，预制桩墙相对的墙面上均设有沿前后方向延伸的桩墙连接槽，预制轨道浇筑在地面上；预制单元包括两个端部预制单元和至少两个拼装预制单元，端部预制单元和拼装预制单元均包括底基、一体浇筑在底基左右两端的侧墙、一体浇筑在侧墙顶部的顶墙和一体浇筑在顶墙与底基之间的中隔墙，底基上设有与预制轨道滑动配合的底基连接槽和底基灌浆管；侧墙上设有与预制桩墙滑动配合的侧墙连接块、侧墙灌浆管和缝隙灌浆管；相邻的预制单元之间插接配合且设有插接灌浆管。本发明将预制结构与现浇进行结合，提高了施工效率。
