Zusammenfassung:	FIELD: construction. ^ SUBSTANCE: method comprises excavating three pits, mounting a wrench in the intermediate pit, preparing two same section of the long pipe for movement, making a pressure-tight chamber in each pipe section, the chamber being defined by the plug at its front end and piston inside it, laying the drawing rope in the exhausted pipe, connecting it to the piston and wrench drum, braking the rope and piston, and moving the pipe by filling the space defined by the plug and piston with pressurized air (gas). Both of the sections of the new pipe move simultaneously from the end pits inside the exhausted pipe to the intermediate pit. ^ EFFECT: reduced repairing period. ^ 2 dwg
