摘要
依托哈尔滨地铁2号线省政府站工程,针对目前地铁暗挖车站临时支护型钢拆除和防水层铺设的不足,开发了"隔一拆二"技术和拱顶施工缝防水层接茬保护技术,解决了高寒地区富水砂层暗挖车站防水技术难题,为今后类似工程提供指导。
Taking the project of Provincial Government Station of Harbin Metro Line 2 as an example,aiming at shortcomings of the dismantling of temporary lining and laying of waterproof layer for metro station excavated by miming method at present,the technology of “one-on and two-off” and the protecting technology of waterproof layer on the construction joints at the station vault were developed.The technical problems of waterproof are solved for metro station constructed by mining method in high cold region and sand stratum with rich water,which will provide guidance for similar projects in the future.
