ABSTRACT:
A pile assembly which is driven into the earth for building foundations of engineering and construction employs a leading pile comprising a hollow column having a plurality of openings formed in a side wall thereof and a lower sharpened tip end and an open upper end, a wedge component having a plurality of elongated wedge members. The wedge component is movable downwardly in a space within the column. The leading pile has a guide component for guiding said elongated wedge members through the openings of the column into the earth when the wedge means is depressed. At least one coupling pile is connected to the leading pile comprising a hollow column having a plurality of openings formed in a side wall thereof and an open lower end and an open upper end, a wedge component having a plurality of elongated wedge members and an inner pillar for depressing the wedge component of the lower pile, which is movable downwardly in a space within the column, and a guide component for guiding the elongated wedge members through openings of the column into the earth when the wedge component is depressed.
