[0036] This embodiment provides a shield machine posture adjustment and modification device, which can return the shield machine 100 to the correct travel trajectory when the posture of the shield machine 100 deviates from the preset trajectory.

[0037] like Figs. 1-3 As shown, the shield machine posture adjustment and modification device includes a fixed part 1, a movable part 2 and a grouting assembly 3, wherein the fixed part 1 is arranged at the center of the tunnel and extends along the travel direction of the shield machine 100, and the fixed part 1 can move synchronously with the travel of the shield machine 100. The movable part 2 is sleeved on the fixed part 1 and fixed to the shield machine 100. A plurality of buttons 11 are arranged at intervals along the circumferential direction on the outer peripheral wall of the fixed part 1, and a plurality of protrusions 21 are arranged at intervals along the circumferential direction on the side of the movable part 2 facing the fixed part 1, and the plurality of protrusions 21 abut against the plurality of buttons 11 in a one-to-one correspondence.

When the shield machine 100 deviates from the preset trajectory, the movable member 2 is simultaneously driven to deviate, causing the protrusion 21 to press the button 11, thereby activating the grouting pump 31, which injects slurry into the outside of the shield machine 100 to push the shield machine 100 back to the correct trajectory. This device can automatically adjust the posture of the shield machine 100, eliminating the need for manual adjustment and achieving rapid adjustment, which helps speed up construction progress.
