METHOD OF MAKING CAST-IN-PLACE PILES WITH ROOT-LIKE MEMBERS AND DEVICE FOR ITS EMBODIMENT Russian patent published in 2001 - IPC

FIELD: construction industry. SUBSTANCE: method includes sinking in ground of hole with subsequent formation of cavities for root-like members at an angle to hole longitudinal axis, and concreting of formed hole and cavities. Novelty in claimed method consists in that root-like cavities are formed from hole by turning of working member compacting the ground relative to hole longitudinal axis with subsequent withdrawal of it to surface through hole. Device for the method embodiment has a tube accommodating working member in the form of cylinder with pointed front part for formation of cavities for root-like members of pile, and drive of working member. Working member is located to execute turning relative to tube longitudinal axis and kinematically connected with drive. EFFECT: extended technological potentialities in making of root-like piles of any diameter, mainly, small ones. 18 cl, 15 dwg
