摘要
北京地铁17号线望京西站至勇士营站区间盾构接收井采用倒挂井壁法开挖,针对盾构井平面尺寸较大、埋深较深的特点,在竖井沉降控制与地下水处理方面采取技术措施,保证了竖井结构稳定和施工安全。
The shield arriving shaft along the interval between Wangjing West Station and Yongshiying Station of Beijing subway line 17 adopted upside-down hanging side wall excavation method. Considering the large plane area of shield shaft and large burial depth, technical measures were adopted for shaft settlement control and ground water treatment, to guarantee the structural stability and construction safety of the shaft.
