The control system uses a measuring device with a servo theodolite (9) behind the tunnelling machine, a target (6, 7) attached to the tunnelling machine and inclination sensors (8), for detecting the roll and longitudinal inclination of the machine. The measurements are evaluated by a processor, for controlling the tunnelling machine drive in dependence on the difference between the actual and required position data, with correction for the variation in the position of the servo theodolite during each measuring cycle, determined via a remote target (12) at the rear. |
