Abstract: Disclosed herein is a head-extended pile with inside and outside reinforcements for supporting load of a structure. The head-extended pile includes a reinforcement part with the same length or area extending right and left with respect to a diameter of the pile provided at the front end of the pile so that a supporting force of the pile is increased, and a durability of the pile is improved by hammering after drilled piling. When the head-extended pile is applied according to the present invention, it improves the stability of proof stress of the pile and construction workability, and better economic efficiency is expected.
