丙烯酸盐双浆液在非降水条件下地铁暗挖隧道止水施工中的应用

APPLICATION OF ACRYLATE TWO-COMPONENT SLURRY IN WATER-STOP CONSTRUCTION OF UNDERGROUND EXCAVATED METRO TUNNELS UNDER NON-PRECIPITATION CONDITIONS

渗水是地下工程普遍存在的问题,防水系统对地铁工程有重要意义。北京某地铁站采用丙烯酸盐双组分浆液防渗防水工艺,避免了施工降水,为该车站顺利开通打下了基础,证明了该做法用于地铁工程的可行性。

Water seepage is a common problem in underground engineering,and the waterproof system is of great significance to metro engineering.A metro station in Beijing adopted an anti-seepage and waterproofing process with acrylate two-component slurry,which avoided construction precipitation,laid the foundation for smooth opening of the station,and proved feasibility of this method for metro projects.
