However, with the development of scheme design, the influence of complex geological conditions and other conditions gradually increases the complex requirements on tunnel excavation, and the tunnel excavation requirements of different diameters appear. For example, designers have extra requirements on the tunnel diameter of a partial section due to functional requirements, but the existing shield machine cannot gradually change the tunneling radius in the tunneling process, so that the excavation of the variable-diameter tunnel at present usually adopts a manual mode, the construction period progress is greatly influenced, the economic benefit is not high, and the safety cannot be ensured. In addition, for the emergency in construction, such as the phenomenon of shield jamming, the shield machine cannot get out of position through itself, needs external rescue, seriously affects the construction period and causes economic loss.

However, the diameter of the cutter head of the shield tunneling machine is changed by turning the turning cutter body relative to the main cutter head, and the turning cutter body can be realized only by a three-dimensional space in the turning process, which is difficult for the underground tunnel excavation environment of the shield tunneling machine.
For another example, chinese patent CN110043274A discloses a variable diameter adjustment structure for soft soil cutter head cutter of shield machine, which includes a cutter head cutter beam, a cutter head outer ring installed on the outer layer of the cutter head cutter beam, and adjustable spokes between the cutter head cutter beam and the cutter head outer ring. However, when the diameter of the cutter head of the shield machine is changed, the cutter head needs to be continuously disassembled and reinstalled, and the tunneling operation of the shield machine needs to be stopped during the diameter adjustment, so that the operation is complex, and the tunneling operation efficiency of the shield machine is influenced by stopping to adjust the diameter.
In conclusion, how to improve the cutter head structure of the shield machine and enable the diameter of the cutter head structure to be conveniently and reliably adjusted in the tunneling process of the shield machine becomes a problem to be solved urgently.
