METHOD FOR DEEP COMPACTION OF SOIL Russian patent published in 2009 - IPC E02D3/10 

FIELD: construction.

SUBSTANCE: invention is related to construction and is intended for compaction of noncoherent and low-coherent soils at high depth for construction. Method includes dynamic impact at soil in place indicated on plan first by deep explosion of explosive charge placed in well, or by electric discharge produced by installation, spark gap of which is placed in well, and then by rammer strokes on soil in place indicated on plan with provision of crater on soil surface, which is periodically filled by draining material of compaction. Charge explosion or electric discharge is executed with intensity that provides for soil compaction in area specified in depth to arrange decompacted zone in the center of this area, and rammer strokes are applied to soil with intensity that provides for at least liquidation of this decompacted zone developed at depth. Compaction material is draining, mostly low-humidity, soil.

EFFECT: simplification of works, and also in increase of quality and depth and volume of soil compaction in the same rammed area.
