Methods for soil compaction of sands and gravels, involves generating vertical vibration movements of compression tool by vibration device which is fitted on upper end of compression tool

摘要

The method involves generating vertical vibration movements of a compression tool (2) by a vibration device (3) which is fitted on an upper end of the compression tool. The compression tool is lowered by its own weight and by the vibration movements on a predetermined target countersink depth. An independent claim is also included for a device for soil compaction of sands and gravels.
