<p>The invention relates to a clamping device on a vibrator, by means of which a pipe (11,12) is rammed into the ground. According to the invention, the clamping device is designed as a pipe collet chuck having at least two partial areas radially outwardly displaceable by means of one or more expanding elements (14, 15), wherein the length of the pipe collet chuck corresponds sub-stantially to the length of the pipe or pipe part to be rammed. The invention further relates to a me-thod for clamping the pipe using the clamping device indicated, which is inserted into the pipe along the entire length of the pipe, before the expanding elements of the pipe collet chuck are actuated for radially expanding for frictionally or positively contacting the internal wall of the pipe to be clamped.</p> |
