摘要
以北京地铁3号线某区间为例,通过对比双侧壁导坑(6导洞)侧墙、拱顶组合模架体系与简易台车体系的模板支撑体系,主要阐述了区间大断面隧道如何利用小型的简易台车进行二次衬砌施工,解决地铁施工场地紧张大型台车无法拼装以及工期效率问题。
Taking a section of Beijing Metro Line 3 as an example,this paper compared the formwork support system of double sidewall heading(6 guide holes)side wall and arch roof combined formwork system with that of simple trolley system.this paper mainly expounds how to use small simple trolleys for secondary lining construction of the section large section tunnel,so as to solve the problems of tight subway construction site,unable assembly of large trolleys and construction period efficiency.
