【摘要】：文章依托北京地铁9号线工程实例,针对北京典型无水大粒径卵砾漂石地层盾构施工所面临的问题,提出了"以疏为主、以隔为辅"的盾构设备选型理念,开展了盾构机刀盘、刀具、加泥及泡沫系统、螺旋输送系统、同步注浆系统、刀盘驱动系统等关键设备的适应性研究和改造升级。实践证明,改造升级后的盾构设备适用于北京典型无水大粒径漂卵砾石地层,极大地提高了掘进速度,降低了建设成本。
[Abstract]:Based on the engineering example of Beijing Metro Line 9, aiming at the problems faced by shield tunneling construction in typical waterless and large gravelly drift-stone strata in Beijing, the paper puts forward the concept of shield equipment selection with "thinning as the main part and isolation as the auxiliary", and develops the shield machine cutter head. Research and upgrade the adaptability of the key equipment, such as tool, mud and foam system, screw conveying system, synchronous grouting system, cutter drive system and so on. It has been proved by practice that the upgraded shield equipment is suitable for typical water-free and large-size bleach gravel strata in Beijing, which greatly improves the tunneling speed and reduces the construction cost.
