Dismantled from the cutting wheel 103 on the face 109, in Fig. 1 Overburden, not shown, is extracted from a mining space 112 arranged on the rear side of the cutting wheel 103 in the advancing direction by means of a mining space 112 in the exemplary embodiment according to FIG Fig. 1 designed as a screw conveyor discharge unit 115 can be discharged counter to the advance direction.
  • FIG Fig. 1 In the dismantling direction at the rear of the cutting wheel 103 and the drive unit 106, the exemplary embodiment is shown in FIG Fig. 1 in the area of a center shield 118, which is not necessarily radially braced for the invention, is equipped with a press bearing designed as a press bearing ring 121, against which the cutting wheel 103 in supported in the axial direction and in which a number of presses 124 operating hydraulically in an axial direction are held.

  • the navigation measurement module 712 feeds, among other things, the central control module 709 with a predetermined target trajectory to be observed for the continuous advancement of a tunnel and at certain times, for example only after a segment ring 139 has been closed or alternatively at least once during the shoring von Tübbingen 133, current navigation data assigned to the actual positioning of the tunnel boring machine.

  • Explained actual force focus 406, advantageously in relation to a clear reference system 721 can be displayed.
  • the pressing force correction module 715 in turn is connected on the output side to a navigation forecast module 724 as a further element of the central unit, with which, given the distribution of the pressing forces exerted by the presses 124 or the press pairs 127, a trajectory forecast over a future trajectory for a certain period of time, for example until one closes next tubbing ring 139 after the last determination of the current actual positioning of the tunnel boring machine, can be determined.
  • the forecast data assigned to the trajectory forecast can be traced back from the navigation forecast module 724 to the central control module 709.
  • the pressing force correction module 715 is connected to inputs of the converter modules 309 in order to use these to control the presses 124 with pressure values in order to provide pressing forces predetermined via the pressing force correction module 715.
  • the calculation of the new contact pressure takes place for an efficient advance, for example, in advance for a period from the start of the shoring of a segment 133 until the completion of the shoring of this segment 133 and thus until the start of the shoring of the next segment 133, but can be especially useful for a high-precision drive or in the case of strongly changing geologies over a small area, also for shorter consecutive periods of time.
  • the pressing force correction module 715 determines new contact forces in such a way that the trajectory forecast determined by the navigation forecast module 724 by stabilizing the actual force center of gravity 406 is at least an approximation of the actual trajectory. expediently within the framework of tolerable smaller deviations from a coincidence of the future trajectory with which the target trajectory takes place for the period of the shoring of new segments 133.
  • the presses 124 or press pairs 127 which are still in contact with tubbing segments 133, are acted upon with the newly calculated pressure values to provide correspondingly assigned contact forces, so that with a continuous advance via the regulation of the position of the actual force center of gravity 406, for example to maintain a position according to Fig. 5 even if you emigrate to an inherently undesirable situation according to Fig. 6 , compared to a position of a target force center of gravity, the predetermined target trajectory is adhered to even during the successive shoring of tubbings 133 without the need for regular interrogation of the actual positioning of the tunnel boring machine, for example during the expansion of a tubbing ring 139.
