FIELD: construction.
SUBSTANCE: invention relates to construction and can be used for laying in pipelines of various purposes. Method involves formation of a channel in the soil, feeding a liquid into which a solution of at least one surfactant and at least one gas-forming agent is added, forming a mixture. Gas formation is carried out directly in soil pores at its contact with gas-forming agent of mixture. Formed channel is sealed with plugs, the said mixture is supplied, filling the channel along its entire length, mixture is held in channel until softening of soil layer around channel along its entire length by conversion of physical and mechanical properties of this soil, then plugs are dismantled. Pipeline is laid with equipment designed to form a channel and equipped with an expander.
EFFECT: reduced power consumption of the laying process, use of equipment which is easy to make and operate in order to realize the method while reducing its cost.
