Date May 22, 1986.The present invention relates to a method and apparatus for compacting by vibrations a soil stratum with the aid of at least one vibration-transferring member (2) which may be driven into the soil stratum, said member transferring vibrations from a vibration generating means (1) to the soil stratum. In accordance with the invention the axial extension of the member (2) is variable both before and in conjunction with the vibration compaction by the member being implemented such as to be resilient, elastic or flexible. |
