DEVICE FOR LAYING PIPES IN THE GROUND

摘要

A device for laying pipes in the ground comprises a percussion mechanism (2) mounted coaxially to the pipe (1) on which is secured a central bushing (3) provided on its external surface with radially oriented ribs (4), and a means (5) for fastening the central bushing (3) on the pipe (1). Said means (5) comprises an additional bushing (6) mounted coaxially to the central bushing (3) and rigidly mounted on the ribs (4), at least three pressing means (3) and three shock absorbers (11), each of them being mounted between the end face of the additional bushing (6) and one of the pressing means (7). The pressing means (7) are spaced evenly along the periphery of the additional bushing (6) and each of them interacts with its end face on the side of the percussion device (2) and with the pipe (1) through openings (8) provided in its wall.
