PROBLEM TO BE SOLVED: To carry out control, in which the judgment of a man is taken, by controlling the direction of a shield machine by a selective output from a jack table, in which a jack pattern corresponding to the place of the center of gravity of a shield jack synthesized is prepared. SOLUTION: The directional control method of the shield excavator is composed of a process, in which the place of the center of gravity of a shield jack based on actual target shield-jack stroke difference is obtained, a process, in which the place of the center of gravity of the shield jack based on an actual target pitching angle is acquired, and a process, in which these places of the centers of gravity of the shield jack are synthesized and a jack pattern corresponding to the synthesized places of the center of the gravity is output selectively. The two obtained places of the centers of gravity of the shield jack are synthesized, and the synthesized place of the center of gravity of the shield jack is determined while the jack pattern having the place of the center of gravity closest to the acquired synthesized place of the center of gravity of the shield jack is selected from a prepared jack pattern table, and output as a signal to a machine-side sequencer. |
