PURPOSE: A hollow CFT making method using a rib steel pipe is provided to manufacture light and cheap post resisting in the use axle load. CONSTITUTION: A steel reinforcing bar and a reinforcement cage are inserted within a lower ribbed steel pipe. An upper rib steel pipe is assembled along with the steel reinforcing bar and the reinforcement cage. A circular steel plate, drilling an air outlet and a concrete inlet on both ends, is the electric pole by welding. Concrete is filled in the concrete inlet. The concrete is rotated and cured in a centrifugal concrete pile manufacturing method.
