METHOD FOR ASSESSMENT OF DRILLED PIPE BEARING CAPACITY Russian patent published in 2010 - IPC E02D33/00 

FIELD: construction.

SUBSTANCE: soil field tests are carried out with punch 6, test results are evaluated, particular value of limit soil resistance under pile foot is identified, at the same time casing pipe 3 is displaced, this displacement is fixed, particular resistance of soil is calculated on side surface of pile, and using superposition principle, bearing capacity of drilled pile is identified as sum of bearing capacity under pile foot and side surface. Method makes it possible, compared to prototype, to increase accuracy of drilled pile bearing capacity assessment up to 10%, to reduce number of piles in foundation grill by 7% as a result of high value of pile bearing capacity and to reduce number of tests by 6% due to high accuracy (validity) of assessment.

EFFECT: increased accuracy of drilled pile bearing capacity assessment.
