Abstract (en)
[origin: WO2011120696A2] The invention relates to a method for operating a horizontal drilling device which comprises a linear drive, a rotary drive that can be displaced by means of the linear drive, and drill pipes that are designed as a string of drill pipes from a plurality of interconnected pipe strands, the rotary drive forming a through-opening into which the drill pipes can be inserted. The through-opening is provided with force transmission means for transmitting compressive and/or pulling forces and/or a torque onto the drill pipes. The invention is characterized in that a pipe strand is fixed inside the through-opening of the drill pipes and is connected to the rear end of the drill pipes or detached from the drill pipes by a linear and/or rotary movement of the rotary drive.
