METHOD FOR DRIVING PILE INTO SOIL Russian patent published in 2015 - IPC E02D33/00 

FIELD: construction.

SUBSTANCE: method for driving a pile into soil consists in determination of pile parameters and hammer parameters, performance of dynamic tests by driving of the pile into soil by means of a hammer with determination of pile faults, as per which and as per pile parameters and hammer parameters, the carrying capacity of the pile is determined as per the specified dependence. Before a pyramidal pile is driven into soil, its weight and cross-sectional area of its upper and lower bases is determined, as per which such a prismatic pile is chosen, the weight of which is equal to the weight of the pyramidal pile. The cross-sectional area of the prismatic pile is equal to half sum of cross-sectional areas of the upper and lower bases of the pyramidal pile. Dynamic tests of this prismatic pile are performed. Load-carrying capacity of the pyramidal pile is determined as load-carrying capacity of this prismatic pile as per the specified ratio of parameters, considering faults obtained during tests of the prismatic pile.

EFFECT: improving operating reliability of buildings and structures at simultaneous increase of a possibility of using pyramidal piles on collapsible soils and in mass construction; improving soil compaction.
