Method and apparatus for compacting soil and / or soil consolidation

The invention relates to a device (1) for compacting soil and / or soil consolidation of sand and gravel, comprising a pillar-shaped compression tool (2) and a vibration device (3), wherein the compression tool (2) is vertically lowered into a ground to be compacted region defined by is to compress vibration of the compression tool (2), wherein the compression tool (2) at least to be lowered at one in the bottom region of the lower end is substantially closed and the vibration device (3) at an upper end on the compression tool (2) can be placed, wherein the compacting tool (2) by the vibration device (3) only in a vertical direction is movable. According to the invention the compression tool (2) at its lower end a tool head (2.1), on which at least one tear open (2.1.2) is arranged, which is about a horizontal pivot axis (S) in a first position and a second position pivotally wherein it is oriented in the first position substantially parallel to the compression tool (2) and is oriented in the second position substantially radially of the compacting tool (2) and projects beyond a diameter of the tool head (2.1) radially. Furthermore, the invention relates to a method for compacting soil and / or soil stabilization of sands and gravels.
