中文摘要:
      依托北京地铁8 号线天桥站—永定门外站区间隧道工程,对砂卵石地层中盾构法施工的钢套筒接收技术开展了相关研究。首先,分析了该工程中盾构接收的难点;然后,对“钢套筒+玻璃纤维筋地连墙”接收方案进行了论述,主要包括钢套筒设计、钢套筒安装及接收准备、盾构接收施工以及洞门封堵注浆等施工环节的关键技术;最后,对钢套筒接收工法的优缺点及经济性进行了比较分析。工程实践表明,本工程中采用的施工控制技术有效确保了盾构接收施工的安全,缩短了施工工期,降低了施工成本。
英文摘要:
      Based on the interval tunnel project from Tianqiao Station to Yongdingmenwai Station of Beijing Metro Line 8, a series of research about the steel sleeve receiving technology for shield tunneling in sandy cobble stratum were carried out. Firstly, the difficulties encountered in the shield receiving process were analyzed. Subsequently, the shield receiving scheme combining the steel sleeve with fiberglass reinforced concrete diaphragm wall was discussed, which mainly included the following key technologies such as steel sleeve design, steel sleeve installation, shield receiving preparation, shield receiving construction and construction of sealing grouting for cave doors. Finally, the advantages and disadvantages as well as the economical efficiency of the steel sleeve receiving construction method were compared and analyzed. The engineering practice shows that the construction control technologies adopted in this project could effectively ensure the safety of the shield receiving construction, shorten the construction period and reduce the construction cost.
