FIELD: building, particularly to consolidate building or building structure foundation base. ^ SUBSTANCE: method involves driving injectors in ground; supplying high-pressure grout through ejectors; recording and measuring mortar pressure and forming grout body. Grout is injected simultaneously through three injectors installed in apexes of imaginary equilateral triangle with side dimensions equal to 5-10 injector diameters. Grout body forming is performed by driving and following lifting injectors for height equal to 1-3 injector diameters before start of grout supply to ejectors. ^ EFFECT: reduced labor inputs and increased efficiency of ground base consolidation due to providing of predetermined grout body shape in horizontal grout breaking plane. ^ 3 dwg, 1 ex |
