Manufacture of compaction columns for ground improvement, by connecting ram to depth vibrator and integrating into depth vibrating process

摘要

A ram (8) is connected to a depth vibrator (5), with a positive connection (9), and integrated into the depth vibrating process, so that layers (3) that cannot be worked through or are difficult to work through, particularly unconsolidated rock and/or landfill material, can be holed through in the compaction material,. An independent claim is included for an apparatus for carrying out the method.
