METHOD TO PROTECT BUILDING STRUCTURE FOUNDATION BUILT IN DEEP SEASONAL FROZEN GROUND AGAINST DEFORMATION APPEARED AS A RESULT OF GROUND HEAVING

摘要

FIELD: building, particularly building structures erected on ground subjected to heaving during ground freezing and subsidence during thawing thereof.;SUBSTANCE: method involves marking compaction points on ground surface and compacting ground. Compaction areas are located on foundation axes or parallel thereto so that the areas overlap one another. Compaction is performed by simultaneous well forming along with rolling out well wall. Material for changing heaving ground properties is placed into well and rolled into well wall. Then the well is filled with nonfrost-susceptible material along with following compacting thereof. Rolled out well depth is not less than depth of seasonal frost penetration in ground.;EFFECT: increased efficiency of foundation protection.;3 dwg
