A method of compacting granular material with continuously vibrating a hollow pipe. The vibrating pipe is lowered into the material to be compacted with a crane type apparatus, maintained in a lowered position for a period of time and then withdrawn from the material. The vibration imparted to the material is increased by a number of annular rings located along the outer surface of the vibrating pipe.

DETAILED DESCRIPTION A method and apparatus for the compaction of granular material comprising an elongated hollow member which is set into vibration by a constant vibrating hammer, the member and hammer being suspended from a crane-like apparatus.
While in constant vibration, the member is lowered into the ground in a substantially vertical position to a predetermined depth, maintained in the lowered position for a period of time, and then withdrawn.
The same procedure is repeated at a plurality of locations.
