Beschreibung
Zusammenfassung:	FIELD: pipelines and their construction. ^ SUBSTANCE: invention is designed for use in trenchless restoration of worn-out pipelines by pipe-in pipe driving and fitting method with pulling length of pipes into pipeline space by pulling wire rope. Invention provides vibratory action onto length of pipes and pulling wire rope to level local deformations of pipeline walls, thus reducing friction of pipe length against walls of pipeline. ^ EFFECT: increased length of pipes pulled through pipelines as to conditions of strength. ^ 4 cl, 6 dwg
