FIELD: building, particularly accurate laying pipeline having large diameter.
SUBSTANCE: method involves forming leading well by removing soil along with adjusting well direction such that mass of removed soil is not less than half of compacted soil mass; compacting well walls; pulling pipeline through the well. Leading well is formed by directional drilling or by cyclical cleanout, for example by means of self-propelled soil extraction device with continuous direction adjustment. Mass of removed soil is preferably directly proportional to soil density on pipeline track.
EFFECT: widened field of application due to possibility of laying pipelines with different diameters, increased accuracy of laying pipeline; elimination of high-power energy installation usage, leaving original ground without change thereof.
