盾构掘进机是一种用于隧道和其它地下工程施工的专用机械。在移动式盾壳内装有各种施工机械,工人在盾壳的保护之下进行隧道开挖、土碴排运、盾构推进和衬砌拼装等一系列作业,使隧道一次成洞。图1为全部采用液压操纵的全断面盾构掘进机。工作时,首先开动大刀盘,边旋转边切割土层;进入盾构内的土块卸到刮板输送机上并连续向后运输,通过胶带运输机或土车转送
Shield boring machine is a special machine used for the construction of tunnels and other underground engineering. Various types of construction machinery are installed inside the mobile shield shell. Workers under the protection of the shield shell carry out a series of operations such as tunnel excavation, soil transportation, shield driving, and lining assembly to make the tunnel become a hole once. Figure 1 shows a full-surface shield boring machine fully hydraulically operated. When working, first start the large cutter head and cut the soil layer while rotating; the earth blocks entering the shield are unloaded onto the scraper conveyor and transported continuously, transported by belt conveyor or earth vehicle.
