Definitions

  • the invention relates to a trench milling machine for the parallel introduction of at least two lines, in particular pipes or cables, into the underground.
  • the trench cutting machine comprises at least two laying units.
  • Each laying unit in turn comprises a milling device for forming a gutter in the ground and a line guide for laying a cable in the gutter formed or imageable by the milling device.
  • the trencher includes a towing vehicle to hen the laying units through the subsurface along an intended direction of travel.
  • An essential advantage of the invention is in particular that at least two lines can be introduced into the ground with the trench cutter in parallel and with a defined and / or constant spacing.
  • a further advantage of the invention is that this is also possible in the case of particularly hard soils or soils in which plowing in the lines is not an option.
