Abstract

A method for operating a horizontal drilling device includes the steps of fixing a rod assembly section within a through-opening formed by a rotational drive of the horizontal drilling device, and connecting the rod assembly section to a rear end of a drill rod assembly of the horizontal drilling device or releasing the rod assembly section from the drill rod assembly by a linear and/or rotational movement of the rotational drive, wherein force transmission means for transmitting compressive and/or pulling forces and/or a rotational torque to the drill rod assembly are provided in the through-opening, wherein the rotational drive is displaceable by a linear drive of the horizontal drilling device, and wherein the drill rod assembly is configured as rod assembly string and is composed of a plurality of interconnected rod assembly sections.
