FIELD: construction, particularly to consolidate ground at building base and poorly stable slopes with the use of jet technology.
SUBSTANCE: method involves determining characteristics of geological elements in geological section of ground massif to be consolidated as distribution member moves from pilot well bottom to upper part thereof, wherein the pilot well is drilled in ground to be consolidated. Geological element characteristics, namely twisting moment and drilling string compression force, are recorded during pilot well drilling. Ground is consolidated in pilot well with distribution member advancing speed determined from mathematical equation. If ground type is changed distribution member advancing speed is regulated.
EFFECT: possibility of ground consolidation by complex ground-and-cement column creation in dependence of ground strength and decreased erection time.
