A method and apparatus for controlling stratum deformation in a shield construction process, a non-volatile storage medium, and a processor are disclosed. The method includes: monitoring settlement characteristic parameters in a shield construction process; predicting a settlement proportion according to the settlement characteristic parameters, the settlement proportion being a ratio between a predicted settlement value and a corresponding settlement threshold; and determining construction parameters in the shield construction process according to the settlement proportion. In the method, a settlement proportion is predicted through settlement characteristic parameters monitored in a shield construction process, and then appropriate construction parameters are determined according to the settlement proportion, so that the construction parameters in the shield construction process can be corrected in real time, and the safety and scientificity of stratum deformation control in shield construction can be ensured.

A system and method for simultaneous excavation and segment erection of Tunnel Boring Machine (TBM) by Thrust shell system is an invention in tunnelling industry which will provide possibility of erection of the segmental ring while TBM is excavating and advancing forward with minimum interruption which will result in significantly increasing of the tunneling speed. The increased speed of the tunnelling will be reducing cost of the construction expressively. At this system and method, the TBM thrust cylinders will be pushing against previously installed segmental ring via combination of a thrust shell and an expandable ring while a new segmental ring is being built by TBM's segment erector within the Thrust shell's provided inner space.

The present invention discloses a movable visual inspection device for shield machines, comprising a rail and an inspection platform. The rail is installed on a shield tail, and the inspection platform includes a bottom plate, a shell, a cleaning mechanism, a power storage control system, and a traveling mechanism. Inside the shell is a visual inspection mechanism with a camera box, a camera, and a stabilizer component. The traveling mechanism drives the bottom plate along the rail. The cleaning mechanism, consisting of a glass sheet, a reel driving part, and a cleaning film, keeps the camera lens clear. The reel driving part rotates the cleaning film, which slides against the glass sheet on the camera box. This invention enables multi-faceted and multi-angle visual inspection of shield machine segments, ensures a clear camera lens, facilitates automatic cleaning and inspection position adjustment, and enhances working efficiency and inspection effectiveness.
