when the whole TBM needs to be controlled to advance, firstly, two groups of second hydraulic rods (302) close to one end of a TBM drill bit main body (1) are controlled to extend through a TBM main control console until two groups of first supporting shoes (304) connected with the second hydraulic rods abut against the inner side of a tunnel, and then two groups of first hydraulic rods (301) are controlled to extend synchronously, so that the whole TBM is pushed to advance, and sliding blocks (303) slide in a sliding groove (306);

after the TBM deviates in the advancing direction, two groups of second hydraulic rods (302) far away from the TBM drill bit body (1) can be controlled to extend, and the other two groups of second hydraulic rods (302) can be controlled to shorten until two groups of first supporting shoes (304) at the rear end of the TBM abut against the inner side of the tunnel, and then two groups of first hydraulic rods (301) connected with the two groups of second hydraulic rods are controlled to extend, so that the whole TBM is forced to retreat in the tunnel;

thirdly, after the TBM drill bit main body (1) returns to a proper position, the third hydraulic rod (9) is controlled to extend until the bottom of the third supporting shoe (8) abuts against the inner bottom of the tunnel, meanwhile, the two groups of fourth hydraulic rods (11) are controlled to extend until the bottoms of the two groups of second supporting shoes (6) abut against the inner bottom of the tunnel, the servo motor (405) is controlled to rotate, the rack (404) and the gear (406) are used for driving, the limiting frame (402) moves towards one side of the TBM, after the moving position of the limiting plate (403) is limited, the one group of first hydraulic rods (301) on one side is controlled to shorten, the corresponding first hydraulic rods (301) on the other side extend, the TBM drill bit main body (1) and the mounting frame (2) rotate by taking the third hydraulic rod (9) as an axis for a fixed angle, the limiting frame (402) limits the position of the limiting plate (403), and the TBM drill bit main body (1) and the mounting frame (2) precisely adjust the angle and then face the correct direction again, so that the TBM drill bit main body (1) and the mounting frame (2) can face the correct direction (ii) a

Fourthly, when the limiting plate (403) rotates by taking the third hydraulic rod (9) as an axis, the limiting plate (403) drives the rolling wheel (14) to rotate, the angle sensor (12) records the rotating angle of the rolling wheel (14), the rotating angle of the rolling wheel (14) is transmitted to the TBM main control console for analysis, and the actual rotating angles of the TBM drill bit main body (1) and the mounting rack (2) are known through the TBM main control console.
