FIELD: construction.
SUBSTANCE: method of trenchless pipe laying in soil, including washing a channel in soil with jets of liquid filled via a pipeline tip as it is laid in the specified direction. Liquid is sent periodically, besides, prior to supply a solution is added with at least one surfactant, and at least one gasifying agent is added, forming a mixture, at the same time gas generation is carried out directly in pores of soil during its contact with the gasifying agent of the mixture. The channel in soil is expanded with jets of the specified mixture directed at the angle to the axis of the laid pipeline. The pipeline during installation is rotated around its axis.
EFFECT: higher efficiency of pipeline laying.
