ABSTRACT:
A reinforced pre-cast concrete pile includes an intermediate cast-in plate attached to cast-in reinforcements of the pile. Following driving of a column of the piles, if the plate of the uppermost pile is above a reference terrain level, then the upwardly projecting part is cut off and that part severed at the lower face of its plate and such upper half is re-used in a subsequent column of piles.
