FIELD: construction.
SUBSTANCE: method includes submersion of a pipe into soil with an open end, formation of a soil core in it and its removal from the pipe with the supplied fluid medium by means of breaking and squeezing out in parts. The fluid medium is supplied into the soil core at the outer side of the submerged pipe, using the channel of connection between the pipeline for supply of the fluid medium and the inner cavity of the submerged pipe.
EFFECT: increased efficiency due to reliability of soil core removal by means of creation of conditions to preserve integrity of a broken part of the soil core.
