Description
Technical Field

Background
In the process of tunneling soil by the underground shield, the shield tunneling face needs shield segments to resist soil layer pressure, underground water pressure and some special loads. The shield segment is lifted to the position of the tunnel face of the shield machine through a small crane arranged in the shield machine, and then the installation work is completed.
At present, the hoisting method of the shield segment mainly comprises the steps of enabling workers to screw the shield segment splicing head into the shield segment by using a spanner, then controlling a shield crane, grabbing the splicing head by using a buckle of the crane, and conveying the splicing head to a tunneling surface for supporting. In the actual assembly operation, the splice and the duct piece are connected together by using a spanner mainly by manpower. The splicing joint has larger resistance in the process of screwing in the pipe piece, and particularly has more obvious resistance in the process of splicing the negative ring pipe piece (the old pipe piece is adopted in most cases). Workers often can only use the traditional method of extending the force arm by using the force application pipe to increase the torque. In addition, the space for assembly operation is narrow, the operation space of workers is limited, and only one or two workers can be provided with the space for assembly operation. The method can only improve the efficiency of segment assembly by alternating workers, and is time-consuming and labor-consuming. The traditional crane only relies on the buckle to nest and assemble the head top, and simple buckle joint strength is not enough, assembles the head and has the probability to drop from the bayonet socket.
