Abstract:
The system, method and apparatus described relates generally to a method of Direct Power Compaction (DPC). In one example embodiment to methods, apparatus, and systems to compact loose ground by vibration and compaction of H piles driven by vibrators or drivers (vibro-hammer). The DPC method is an efficient and highly economical technique for densifying loose soils. In the procedure piles, with an innovative H pattern structure, are driven in the ground using a combination of downward and vibratory force to move particles of the loose or sandy soil closer together and reduce the voids between them. Subsequent backfilling and vibration at the H-pile sites achieves the highest density possible and provides for an improvement ground soil structure and load bearing capacity.
