摘要
针对在城市复杂环境条件下,无法设置常规盾构接收井的情况,以北京地铁六号线花园桥站—白石桥南站区间为例,提出设置单井+暗挖横通道的组合接收井方案;并依据海瑞克EPBφ6 250土压平衡盾构机的尺寸控制,详细介绍拆卸螺旋输送机、盾构机旋转、平移、吊出等接收方案,为以后类似工程的设计提供参考。
It is unfeasible to install a conventional shield arriving shaft in complex urban environment.Regarding the arriving of the shield of the bored running tunnel from Huayuanqiao Station to Baishiqiao South Station on No.6 Line of Beijing Metro,the proposal of ＂single shaft ＋ mined cross adit＂ is made.In addition,screw conveyor disassembly option,shield rotation option,parallel shield moving option and shield hoisting-out option are described in detail on basis of the control dimensions of Herrenknecht EPB φ6250 EPB shield.This paper can provide reference for similar projects in the future.
