FIELD: pipeline construction.

SUBSTANCE: invention relates to the field of laying pipelines. The method for trenchless pipeline laying through natural and artificial obstacles consists in the fact that a whip of pipes equipped with a protective composite coating is forced into a tunnel produced by a tunneling complex located in front of the whip of pipes.
