PURPOSE: A PHC(Pretensioned spun High strength Concrete) pile for rotational penetration is provided to construct the pile through rotational penetration by equipping a spiral wing, and to maximize the load support force of a structure. CONSTITUTION: A PHC pile(1) for rotational penetration comprises a plurality of PHC piles(10) and a spiral wing(20). The plurality of PHC piles is shaped into a hollow cylinder, is surrounded by a reinforcing band on the circumference of both ends, and is linearly arranged into desired numbers in consideration of the penetration depth of the pile. The spiral wing is mounted on the reinforcing band by a joint side opposing two neighboring PHC piles, and comprises a first wing(21) with an upper wing piece(210) and a second wing(22) with a lower wing piece(220). |
