随着盾构机在隧道施工中的广泛采用,无论气压平衡盾构、泥水平衡盾构、土压平衡盾构以及复合式盾构,其安全、高效、经济、环保等优点都非常突出。城市地铁因地质围岩状况、地表建筑物分布、地下水含量和埋深等的不同,盾构机的操作方法及推进参数也不同。本文以德国海瑞克EPBD6250型复合式盾构机在广州地铁隧道施工情况,介绍常见作业故障的处理。 With the widespread adoption of shield machine in tunnel construction, the advantages of safety, high efficiency, economy and environmental protection are prominent regardless of pressure balance shield, mud balance shield, earth pressure balance shield and composite shield. Urban subway due to the surrounding rock conditions, the distribution of surface buildings, groundwater content and depth of the different, shield machine operation methods and propulsion parameters are also different. In this paper, the German Herrenknecht EPBD6250 composite shield tunnel construction in Guangzhou Metro, describes the common operation of the fault handling.
