METHOD OF LIFTING AND LEVELING OF BUILDINGS/CONSTRUCTIONS Russian patent published in 2018 - IPC E02D35/00 

FIELD: construction.

SUBSTANCE: method of lifting and levelling buildings/constructions involves the installation of injection pipes and the injection of mobile mortar under the building/construction. Injection cuff pipes under the building/construction are installed horizontally in two stages. At the first stage the sandy soil is conditioned, which makes it possible to redistribute the ground material around the injector in a given radius. Injection of the main injection solution in injectable sleeve pipes, in each of which the injection solution is applied repeatedly to create volumetric bodies of the injection material at strictly defined points of the core, is executed in the second stage.

EFFECT: providing the possibility of redistribution of ground material around the injector in a given radius for its subsequent compaction during the injection of injection solution, increasing efficiency of lifting and levelling of constructions.
