[0002] A shield machine is a tunnel boring machine that uses the shield method. The shield construction method is that the tunnel boring machine builds a tunnel shield while excavating. It is different from the open construction method. The basic working principle is that a cylindrical steel component advances forward along the axis of the tunnel while excavating the soil. The shell of the cylindrical component is the shield, which plays a temporary support role for the excavated tunnel section that has not yet been lined. Shield machines are generally divided into hand-dug shields, extrusion shields, semi-mechanical shields and mechanical shields according to their working principles. After the project is completed, the shield machine needs to be disassembled.
