Abstract (en)

[origin: EP1069244A2] The method involves using a depth vibrator (11), which is inserted and withdrawn in the ground from an unbalanced mass vibrating about a vertical longitudinal axis. The unbalanced mass is suspended by a pipe screwed to a joint coupling and by a steel cable running in the pipe, which is guided through the pipe. The unbalanced mass is driven with alternating rotation directions, and is varied with time. An Independent claim is included for a depth vibrator for use with the method.
