PURPOSE: A construction method of a pile which does not require a foundation is provided to improve cost-efficiency because a foundation installed between a column and a pile is not required. CONSTITUTION: A construction method of a pile which does not require a foundation is as follows. A pile insertion hole is bored in a position where a column is installed. The verticality of the bored hole is confirmed, and concrete is injected into the bored hole. A high-strength large-diameter reinforcing bar is arranged inside the concrete. A centrifugal high-capacity pile(4) is inserted into the bored hole. The empty space between the centrifugal high-capacity pile and the bored hole is filled with concrete. A base plate of a column is fixed to an uppermost end steel plate of the centrifugal high-capacity pile.
