METHOD OF SOIL REINFORCEMENT Russian patent published in 2015 - IPC E02D17/20 

FIELD: construction.

SUBSTANCE: method of soil reinforcement includes filling, levelling, compaction of a soil layer, arrangement of reinforcing elements on the surface of the soil layer and their filling with soil of the next layer. At the same time reinforcing elements arranged on the surface of the soil layer are made in the form of concrete slabs having vertical holes in their body in the form of cones truncated downwards, designed for provision of filtration processes and increased adhesion of concrete slabs with soil after embankment filling. Concrete slabs arranged on the surface of the soil layer of embankment are made by filling of the form with concrete mix with metal elements installed inside in the form of truncated cones, which provide for production of holes in the concrete slab. Besides, internal dimensions of the form correspond to external dimensions of the concrete slab, and the position of the concrete slab in the body of embankment, number and location of holes in the slab depend on the specified calculation. At the same time the concrete mix in the form of coarse filler and reinforcing material contains wastes of casting production in the form of slag.

EFFECT: increased stability and operational reliability of soil embankment due to increased forces of embankment soil adhesion to a reinforcing element.
