The invention relates to construction engineering, in particular to soil compacting process and means for building and comstruction works. The aim of said invention is to extend operational possibilities by compacting disperssed bound soils such as clays, sandy clays and slay sands, also unbound dispersed soils such as sands and filled technogenic soils by injecting a mortar exhibiting a high-penetration capability into the soil. The inventive soil compacting method consists in injecting a cement mortar into the soil with the aid of injectors which are embodied in the form of perforated tubes provided with simultaneously destractable plugs, wherein said injection is carried out through or under a cement slab which is placed on the unbouned soil, is embodied in the form of a dead weight or carries a dead weight arranged thereon in order to ensure the soil hydraulic fracturing at a hydro fracturing pressure ranging from 3.o to 20.0 atm. |
