FIELD: construction.
SUBSTANCE: invention relates to construction, particularly, to horizontal drilling technologies and equipment for trenchless laying of pipelines. Method of laying pipes is based on the technology of horizontal directional drilling with or without the use of destruction method. Prior to pulling a pipe into the trench its outer diameter is increased to match the diameter of its bell with application of a low friction coefficient and/or smaller soil sticking coefficient coating on the aligned surface.
EFFECT: technical result is broader functional capabilities and higher reliability of pipelines laying.
