FIELD: construction.
SUBSTANCE: invention relates to mining and construction equipment, is used to lay pipes in soil with open end with their simultaneous cleaning from soil. Method includes tunnelling of pilot hole, formation of working well with pulling of pipeline in it with the help of pneumatic impact device by means of soil development and movement into pipeline cavity. Soil plug is also formed with the help of previously created obstacle, afterwards it is removed, using spent compressed air from pneumatic impact device.
EFFECT: increased efficiency of works and reduced energy intensity of the process.
