SLIDING SLOPE CONSOLIDATION METHOD Russian patent published in 2006 - IPC E02D3/12 

FIELD: building, particularly to prevent slope ground sliding during industrial territory development.

SUBSTANCE: method involves driving injectors into sliding ground along profiles spaced apart 1.0-2.5 m, wherein the injectors are spaced apart 1.0-2.5 m and directed transversely to sliding ground edge and are submersed for depth 0.5-1.5 m below ground sliding plane; injecting consolidating mixture under increasing pressure to create hydraulic fracturing cavities; injecting consolidating mixture under constant pressure, which 1.1-1.3 times larger than ground pressure to create compacted zones having radii of 1.5-2.5 m around the injectors so that the compacted zones are overlapped or touch each other. During injector driving in ground having coarse cut rock pieces small-diameter pilot well is drilled. The pilot well diameter may be equal to 60 mm. The injector is installed in the well and forced in ground for necessary depth. After injection operation termination injector heads are sheared and plugged.

EFFECT: increased ground physical and mechanical properties for all sliding ground thickness and increased ground stability.
