FIELD: construction.
SUBSTANCE: device for trenchless installation of pipelines by means of piercing comprises a hollow working tip of conical shape connected via a hinged joint and a support of rotation with a shaft, installed in rotation supports on a flange, which is mounted on the front end of the installed pipeline, in direction of piercing, a vibrator of circular oscillations, a vibrator drive installed in the laid pipeline and a feed mechanism. The vibrator of circular oscillations is arranged in the form of movable weights capable of radial displacement in guides rigidly fixed on the shaft, at the same time movable weights via solids of revolution are pressed by means of springs to the inner conical surface of a ring, installed in a hollow working tip capable of axial displacement by "screw-nut" transfer.
EFFECT: higher efficiency of device operation in soils with various physical-mechanical properties.
