Abstract

In a device and a method for continuously driving a tunnel along a desired setpoint trajectory there is provision to influence pressing forces which are applied to installed tubbing segments by compactors using a control circuit, wherein, during the driving and during the installation of tubbing rings, an actual trajectory of the device remains in a region which is permissible for maintaining the desired set point trajectory.
