FIELD: construction.
SUBSTANCE: device for trenchless laying of pipelines by piercing comprises a working tip of conical shape, a vibrator of circular oscillations of which is arranged in the form of an electric motor with a hollow shaft, the stator of which is fixed in the working tip, and the rod is installed inside the hollow shaft, having a displaced centre of gravity relative to the axis of rotation, at the same time the rod is fixed on the flange, which is mounted on the front end of the laid pipeline along the piercing direction. The rotation device is arranged in the form of a cover with a hole, rolling in displaced surfaces of the rotating eccentric reciprocally moving along the longitudinal axis of the rod.
EFFECT: higher accuracy of pipeline laying.
