FIELD: building, particularly to construct pile foundation in territories with severe climatic conditions.
SUBSTANCE: pile foundation with grillage includes piles driven in seasonally frozen heaving soil, grillage to connect pile heads supported directly by heaving foundation soil. Pile heads have reinforcement rod projections extending for at least 150 mm and welded with anchoring rods located in grillage body. Summary area of extended reinforcement of one pile, maximal pile stretching force and actual value of pile foundation buckling are determined from given relations taking into consideration that maximal admissible relative buckling difference is to be more or equal to actual value.
EFFECT: reduced material consumption and labor inputs, increased reliability and enhanced pile foundation operation during building and building structure usage.
