北京地铁10号线团结湖站穿越桥桩区、拱部地层为粉细砂层,有多条市政管线近接或侵入结构体,因此,支护框架体系中“拱”的形成具有极大难度。重点介绍车站扣拱方案与扣拱施工技术,包括整体扣拱方案的确定、初期支护扣拱施工、二衬施工及沉降监测与信息反馈等。
Tuanjiehu Station of Beijing Metro Line 10 crosses the bridge pile area and the arch of the arch section is silty sand layer. There are several municipal pipelines near or intruding into the structure. Therefore, the formation of “arch” in the supporting frame system is extremely large Difficulty. It mainly introduces the construction of buckle arch construction and buckle arch construction at station, including the determination of the overall buckle arch construction, the initial support buckle arch construction, the construction of the second lining and the settlement monitoring and information feedback.
