简易门式支架在城市地铁轨行区交叉施工中的应用

Application of simple portal bracket in urban subway track area crossing construction

以成都目前在建最大地下车站九江北站盾构井、轨排井结构施工为例,采用简易门式支架代替满堂式脚手架施工盾构井、轨排井,解决轨行区各专业交叉施工的影响,极大节省了施工成本和工期,以供今后类似城市地铁轨行区交叉施工参考和借鉴。

Take Jiujiang North Station,the largest underground station currently under construction in Chengdu,as an example,the shield well and rail track well structure construction,using simple portal bracket instead of full scaffolding construction shield well and rail track well,to solve the iMPact of cross-construction of various specialties in the rail track area,greatly saving construction costs and construction period,for future reference and reference of similar urban metro rail track area cross-construction.
