Abstract

The invention discloses an automatic calibration shield segment. The segment comprises an arc-shaped segment body, an annular groove and a longitudinal groove, a calibration groove is formed in one side of the arc-shaped segment body, the calibration groove is a table-shaped groove, a clamping frame is rotatably connected to one side of the inner wall of the calibration groove, and swing grooves are symmetrically formed in one side of the inner wall of the calibration groove. Position correcting devices are installed in the swing grooves, and calibration plates are symmetrically installed on the side, away from the calibration groove, of the arc-shaped segment body. The invention relates to the technical field of tunnel construction. According to the automatic calibration shield segment, the purpose of facilitating calibration between shield segments is achieved, the installation difficulty of the shield segments is reduced, unevenness between the shield segments can be avoided, the butt joint position of the shield segments is automatically calibrated, the inspection work after the shield segments are installed is reduced, the tunnel construction efficiency is improved, damage caused by collision between the shield segments is reduced, the service life of a tunnel is prolonged, and the firmness degree of connection between the shield segments is improved.

Description

technical field [0001] The invention relates to the technical field of tunnel construction, in particular to an automatic calibration shield segment. Background technique [0002] At present, tunnel construction methods include open-excavation method and underground excavation method. Among them, the shield tunneling method in the underground excavation method is a fully mechanized construction method. Because the shield tunneling method has the advantages of safe excavation and does not affect the facilities on the ground, it is favored. It is widely used in tunnel construction, such as railway tunnels, highway tunnels, underwater tunnels, underground railways, etc. The shield machine includes the main machine and three supporting frames behind it. The front end of the main machine is a cutter head, and different tools are installed on the cutter head. , the motor drives the rotation of the cutter head, and several groups of hydraulic jacks push the cutter head forward, so ...
