METHOD OF BULK SOIL CEMENTATION Russian patent published in 2018 - IPC E02D3/12 E02D27/08 

FIELD: construction.

SUBSTANCE: invention relates to the field of construction and can be applied in the engineering preparation of construction sites for new construction. In the method of bulk cementation of sandy, sandy loam, loamy soils and light clays, comprising the preparation of an aqueous portland cement slurry with a water-absorbing mineral component and introducing a prepared slurry into the soil, preliminary removal of soil containing organic impurities is carried out, in the pit formed, an aqueous suspension is prepared by uniformly mixing portland cement and water in a ratio of 1:1.2, sandy loam or loam is introduced into the suspension while stirring, to form a paste, a water-absorbing mineral component is introduced into it – a steel-smelting, or blast-furnace, or phosphoric slag, the composition of the rigid hardening mixture contains said components in the following ratio, by weight: portland cement 5–20, slag is not more than 40, water 6–20, sandy loam or loam – the rest, while bulk cementation of these soils use single-bucket excavators.

EFFECT: technical result is the development of a technological method for bulk cementation of soils and the installation of anti-filtration curtains in solving the bearing capacity of the foundation.
