Claims (5)

1. The method of compaction of the soil, including immersion in the soil of the injector, feeding the solution under pressure, measuring and recording the pressure of the solution, the formation of the zone of compacted soil and subsequent immersion of the injector with the formation of adjacent zones of compacted soil, characterized in that the dispersed soil is compacted by pumping the compacting and penetrating solution, ensuring the destruction of the soil structure in the zones of its weakening, with preliminary compaction of the soil along the contour of the compaction zone.  2. The method according to p. 1, characterized in that when compaction of water-saturated low-filtering soil, the flow rate of the solution is limited by the rate of outflow of water from the zone of compacted soil.  3. The method according to p. 1, characterized in that when the loess soil is compacted, the soil is pre-soaked with water supplied under pressure exceeding the structural strength of the soil.  4. The method according to p. 1, characterized in that the sealing and penetrating solution contains a rigid skeletal material, such as sand, which prevents shrinkage when the solution dries.  5. The method according to p. 1, characterized in that the composition of the sealing and penetrating solution is selected so as to ensure its plasticity in the process of compaction of the soil, depending on the filtration coefficient and the pressure of the solution.
