Ground consolidation by a rubble piles

The method is applied since 1990, protected by the patent ¹2026926 from 20.01.95

The method is successfully used in clayey grounds semifirm and hardly a semifluid consistency, in sandypriming coats, dry and there are not enough damp.

Consolidation of priming coats of the base is carried out by a rubble or concrete ramming in the slope driven wells passed by a pneumomandrel plug under a sole of the bases.

After consolidation in 2-2,5 times resistance of a ground increases and at 5-10 times amplitudes of vacillatings of the bases from movement of motor transport and underground trains decrease.
