METHOD FOR DRIVING PILES Russian patent published in 2018 - IPC E02D7/08 

FIELD: construction.

SUBSTANCE: invention relates to a construction, namely a method for optimizing pile driving. Method for optimizing pile driving, in which a pile is driven into the ground by a pile coprode containing a copra female to be placed in an abutment against the pile, and a block moving forward and backward therein. Moving the block used to drive the pile toward the end of the pile with a specified shock energy (W_kin). Determination of the magnitude of the impact kinetic variable (Q1) proportional to the kinetic energy of the block used to drive the pile when the block moves to the pile in the pile driving direction. Determination of the magnitude of the kinetic variable (Q3) of the reverse movement, which is proportional to the kinetic energy of the block, when the block returns after hitting the pile, in the direction opposite to the pile driving direction. Calculation of the ratio (Q1/Q3) of the kinetic variables with the help of certain impact kinetic variable (Q1) and kinetic variable (Q3) of the reverse motion. Comparison of the obtained ratio (Q1/Q3) of the kinetic variables with a given target value (Q1/Q3_tav) for the ratio (Q1/Q3) of the kinetic variables, with the shortest possible total time (t_tot) clogging for piles. Regulation of shock energy (W_kin) of the next impact so that the ratio (Q1/Q3) of the kinetic variables determined by the impact kinetic variable (Q1) and the kinetic variable (Q3) of the reverse movement of the next impact, has changed, approaching the set value (Q1/Q3_tav).

EFFECT: technical result is improvement of accuracy of determining the bearing capacity, reduction of material consumption and labor intensity of tests.
