A long-shaft tool includes a shaft extending along a longitudinal axis and having a handle at a first end of the shaft and a second end opposite the first end with a holder for a manipulator wherein the holder has a protruding latch pin provided for engagement with a recess of a manipulator, which can be moved from the protruding position into a retracted position. The holder has a coupling half for coupling with a coupling half of a manipulator which is rotatable relative to a base body of the shaft.

A mixing system for producing a drilling fluid for ground drilling includes a feed for a powdered medium and a mixing chamber with a feed for a fluid medium. A space is provided between the feed for the powdered medium and the mixing chamber, having sliding elements therein, which sliding elements can seal off the space at one end.

A rod section having an electrical conductor which is arranged such that it is centered at the end and has an insulating sleeve and is fixed in the rod section such that when the rod section is joined to a further rod section having a fixed conductor, both conductors are joined together in a forcibly guided manner and the join is sealed by the sleeve in a forcibly guided manner.

Rod section and rod section system

The invention relates to a tool for longitudinally subdividing buried sewer pipes having an asymmetric, generally oval cross section, made substantially of a support shoe opposing a cutting blade acting in the direction of the pipe axis. The device also has two side cutting blades and is moved through the old pipe by means of a rod and a cylindrical calibration mandrel.

A method for in-situ repair of old underground pipes is disclosed. A breaking tool with a drive or a pipe section is pulled from a typical inspection shaft to the next inspection shaft (machine shaft) by a hydraulic piston-cylinder unit which has a housing that is at least partially located inside the old pipe. The extremely limited interior space of the machine shaft is thereby kept essentially free from machine parts.

Method and device for reconstructing old underground pipes

The invention relates to an apparatus and a method for joining a pipe conduit to a drilling device, expanding device or pull-in device, in which a pulling-force generator arranged in the drilling device, expanding device or pull-in device exerts a compressive force on a pipe conduit, to be pulled in, via a pulling means and an adapter and thereby holds the individual short pipes of the pipe conduit together and reduces the mechanical stress to which the short pipes are subjected.

A cutting device for cutting or bursting a pipeline includes a basic body having at least one cutting or perforating element, wherein the cutting or perforating element discontinuously cuts the pipeline in the longitudinal direction or at least discontinuously weakens the pipe material.
