METHOD FOR DEPTH COMPENSATION COMPACTION OF SOIL Russian patent published in 2010 - IPC E02D17/00 

FIELD: construction.

SUBSTANCE: method for depth compensation compaction of soil in construction of underground object by means of compensation compaction of soil at the side of secured structure near constructed underground object, where at the side of secured structure zones of easy-to-compact soil are detected in depth of soil mass before decompaction spreads towards secured structure by the distance critical for secured structure, hardening material is supplied into detected zones of easy-to-compact soil under hydrostatic pressure, and serially (by turns) in each detected zone of easy-to-compact soil along mass depth, depth compensation compaction of soil is carried out in specified zones by discrete dynamic pulses until soil compaction is rejected, adding hardening material, if required.

EFFECT: increased reliability, quality and manufacturability of anti-deformation barrier formation, reduced labour intensiveness of works for provision of integrity of buildings located in zone covered by works of deep pit arrangement, with minimum consumption of resources and maximum possible usage of soil mass properties.
