城市轨道交通工程区间人防门“吊模法”施工技术研究

城市轨道工程地下线作业空间狭小、施工单位多,交叉施工情况严重;地铁车站内人防门框墙施工与装修施工、轨道施工、土建结构施工、附属施工同步进行;车站范围内交叉施工严重,协调难度较大;传统地铁区间人防门施工中采用支撑立模法,这种施工方法需要占用轨行区搭设支架与轨道施工相互制约;采用“吊模法”施工地铁区间人防门,解决了模板支架影响轨道车通行的问题。

The working space of the underground line of the urban rail project is narrow,there are many construction units,and the cross construction is serious;the civil air defense door frame wall construction and decoration construction,track construction,civil structure construction and ancillary construction in the subway station are carried out at the same time;the cross construction within the scope of the station is serious,so it is difficult to coordinate.The support formwork method is adopted in the construction of the civil air defense door in the traditional subway section,which needs to occupy the track area to set up the support and restrict the track construction,and the"hanging formwork method"is used to construct the civil air defense door in the subway section.the problem that formwork support affects the passage of rail cars is solved.
