摘要
对于地下空间超宽的地下车站,为了确保钢支撑结构的安全,需要设置支撑钢作为临时立柱。以北京望京西站为例,介绍了临时立柱设计及施工工艺流程,并针对格构柱尺寸狭小难以设立临时立柱的问题,采用了普通焊接钢管灌注混凝土工艺的解决方法。
To guarantee the safety of steel supporting structures in metro station extra-wide underground space, temporary steel columns as supporting structure are needed. To take the Wangjing west metro station of Beijing subway as an example, introduced design and construction technological flow of temporary columns. In allusion to small size of lattice column thus hard to construct temporary columns, the common welded steel tube concrete grouting technology is used.
