Station hall layer support construction method for underground excavation station track laying and station hall layer parallel construction
The invention relates to the technical field of tunnel construction, in particular to a station hall layer support construction method for underground excavation station track laying and station hall layer parallel construction. 2, reinforcing steel bars are reserved in advance during station inverted arch construction; 3, reinforcing bars are reinforced according to the position of a portal frame foundation during station secondary lining construction, secondary lining concrete is poured, and after secondary lining concrete pouring is completed, a foundation is formed after formwork removal; 4, gantry steel pipe columns are installed on the reserved foundation of the second lining, then longitudinal beams and cross beams of a gantry are installed, and finally supports are installed on the cross beams; the support and the spanning type portal are combined with corresponding characteristics, and the reserved door opening serves as a construction channel and a track laying channel, so that track laying operation and station-crossing track laying construction can be organized under the condition that the support, located in a track traveling area, of a station hall layer is not dismantled; the problems that in the prior art, a station hall layer support is long in service time, concrete age time is long, and track laying operation entering construction is delayed are solved.
本专利涉及隧道施工技术领域，具体是暗挖车站铺轨和站厅层平行施工的站厅层支架施工方法，包括以下步骤：步骤1：确定站厅层门架基础位置；步骤2：车站仰拱施工时提前预留加强钢筋；步骤3：车站二衬施工时根据门架基础位置加强配筋，浇筑二衬混凝土，二衬混凝土浇筑完成、拆模后形成基础；步骤4：在二衬预留的基础上安装门架钢管柱，随后安装门架的纵梁和横梁，最后在横梁上安装支架；利用支架、跨越式门架结合相应特点，预留的门洞作为施工通道和铺轨通道双用通道，实现站厅层位于轨行区的支架在不拆除的情况下即可组织铺轨作业和过站铺轨施工，解决了现有技术中站厅层支架使用时间长、混凝土龄期时间长进而延后铺轨作业进场施工的问题。
