FIELD: pipelines.
SUBSTANCE: invention relates to trenchless methods of laying and replacing pipelines using hose technology and preparing the hose in place. Method of trenchless pipeline laying includes drilling of pilot well, its expansion, sealing and pipe inlet. Flexible sleeve impregnated with a polymer thermosetting binder in a viscous-fluid state is introduced into the well simultaneously with the reverse stroke of the drilling head with a dilator with the possibility of formation after tubular structure hardening in the well. Disclosed is a device for tightening articles in pipelines.
EFFECT: technical result consists in possibility of erection of pipelines and conduits of complex configuration and formation of multilayer shells in minimum number of passes.
