FIELD: construction.
SUBSTANCE: invention is related to the field of construction, namely to devices intended for trenchless installation of pipelines by method of puncture, and may find application for arrangement of hidden passages in construction of pipelines, underground communication cables and power transmission lines. Device for trenchless installation of pipelines by method of puncture comprises hollow working tip of conical shape, which connected via hinged joint and rotation support with rod fixed on flange mounted on the front end of installed pipeline according to puncture direction, vibrator of circular oscillations installed inside hollow working tip. Vibrator of circular oscillations is made in the form of electric motor with hollow shaft, stator of which is fixed in working tip, and rod is installed inside hollow shaft having displaced centre of gravity relative to axis of rotation. At the same time rod is fixed on flange.
EFFECT: improved reliability and efficiency of device operation.
