摘要
上海轨道交通市域线机场联络线地下段工程在国内首次将预制弧形件、预制中隔墙工艺运用在Φ14.02 m大直径盾构隧道中。受隧道距离长、工期短的限制,将采用专项研发的拼装设备进行预制中隔墙拼装。介绍了上海市域铁路机场联络线的基本状况及设计理念,阐述了该工程中隔墙的拼装方案、施工难重点,可供后续项目参考。
For the first time in China,the technology of prefabricated arc parts and prefabricated middle partition wall is applied to the underground section of airport connecting line of Shanghai rail transit city line Φ14.02 m large diameter shield tunnel.Due to the limitation of long tunnel distance and short construction period,the prefabricated middle partition wall will be assembled with specially developed assembly equipment.This paper introduces the installation scheme,construction difficulties and key points of the middle partition wall in the project.It can be used as a reference for subsequent projects.
