The invention pertains to a machine for producing or widening ground bores and/or for shattering old pipelines and laying new pipelines, consisting of a push-pull unit and a rod assembly that is connected to and driven by the push-pull unit and extends through the ground bore or the pipeline, with projections and/or recesses being arranged on the rod assembly, and with positive coupling means that engage on the projections or in the recesses arranged on the push-pull unit.

Ground-boring machine

A device for connecting a pipeline conduit to a ground-boring machine or for replacing old pipes and inserting the end of an individual pipe into a sleeve joint of the preceding pipeline conduit, comprising a tensioning frame that can be attached to the end of the pipeline conduit or the individual pipe to be connected thereto, a tensioning drive on the tensioning frame, and a cable or chain that is coupled to the machine as well as the tensioning drive.

Device for connecting a pipeline conduit to a ground-boring machine

Arrangement of an impact-sensitive device in a housing, particularly a transmitter for locating a drilling device located in a borehole in the ground, wherein the device is maintained within same by means of at least one impact-damping buffer at least in the main direction of impact and at a distance from the wall of a chamber accommodating the device.
