Abstract:
In a method and an apparatus for replacing old underground conduits (4), the old conduit (4) is first laid bare with the aid of a ground drilling device (8) with an overdrilling head and then, in turn, a new conduit (5) is drawn in with the aid of the drill rods (7) and at the same time—in a uniform operating step—the old conduit is pulled out of the ground.
