Abstract
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.
