FIELD: bulkheads, piles, or other structural elements specially adapted to foundation engineering, particularly concrete or concrete-like piles cast in position with enlarged footing or enlargements at the bottom of the pile.
SUBSTANCE: reinforcement device is used to erect pile foundation with the use of foundation pile having at least one longitudinal cavity. Reinforcing device comprises a number of joined reinforcement members hingedly connected with central annular member located so that reinforcement device may be collapsed during installation and erected during device usage. Reinforcement device is connected to pile by at least one member working in tension. Foundation pile reinforced with the use of said device and method for foundation pile driving and pile bottom reinforcement are also disclosed.
EFFECT: increased uniformity of reinforcement distribution over pile bottom, improved compression and stretching force damping, decreased labor inputs and material consumption.
