摘要
根据高速铁路的运营养护特点,在广深港高速铁路狮子洋隧道设计过程中提出了盾构管片接缝防水采用双道密封与分区隔断的防水技术方案。文章针对弹性密封垫防水特点,分析了弹性密封垫及分区防水的关键技术参数,并针对弹性密封垫的正常工作状态,提出了接缝的错台量、张开量及施工期沟槽修补要求。
Considering the characteristics of operation and maintenance of high-speed railways, all option featuring a double seal and partition separation was adopted in the waterproofing design for the segment joint in the Shiziyang Tunnel on the Guangzhou-Shenzhen-Hongkong high-speed railway. The key technical parameters of an elastic seal gasket anti partition separation are analyzed in regard to waterproofing, and the requirements for joint staggering, joint opening, and groove repair during construction are addressed.
