FIELD: construction engineering; repair of pipe lines by trenchless method. SUBSTANCE: proposed device includes central rod surrounded by elastic envelope made in form of hose impregnated by reinforcing binder; it is located between inner and outer separating films; device is also provided with coat embracing the elastic envelope and protective casing. Sectional central rod is provided with blanks fitted at its ends and oriented towards each other by their closed; ends; these blanks have different diameters of section; ends of elastic envelope and inner separating film are secured on surfaces of larger diameter of blanks and ends of additional inner envelope are secured on surfaces of lesser outer diameter of blanks forming hermetic cavity between these envelopes; protective casing is rigid. EFFECT: enhanced reliability of pipe line. 5 cl, 4 dwg
