FIELD: construction, particularly consolidation of water-saturated ground bases of engineering structures.
SUBSTANCE: method involves treating ground with gas and introducing consolidation mix in ground. Ground is consolidated in several layers beginning from lower layer by driving injection with releasable bit to lower layer of ground to be consolidated. First of all ground is treated to dewater zone to be consolidated by air injection through side orifices of injector at pressure exceeding pressure generated by gravity of ground under compacted layer, but is not sufficient for natural ground structure damage. Then consolidation mix is injected in ground through side and lower injector orifices. During ground consolidation injector is removed from ground up to next layer to be consolidated.
EFFECT: increased efficiency of water-saturated ground consolidation and extended range of materials to be used for ground consolidation.
