The purpose of the present invention is to provide a method for constructing a prestressing steel and concrete composite pile, which prevents the risk of corrosion by composing concrete outside a steel pipe, improves bending performance and durability by introducing prestressing to the concrete using pretension release PS steel, maintenance release PS steel, and posttension release PS steel and, in particular, constructs an economical and reasonable cross section by installing steel and concrete composite piles in tensile and compressive sections. To achieve the above purpose, a method for constructing a prestressing steel and concrete composite pile according to the present invention comprises the steps of: producing a prestressing steel and concrete composite pile, which comprises a steel pipe having a predetermined diameter and length, shear connecting materials welded on the outer peripheral surface of the steel pipe, steel reinforcement fixed to the outer peripheral surface of the steel pipe, pretension release PS steel fixed to the outer peripheral surface of the steel pipe, and concrete deposited and cured on the outer peripheral surface of the steel pipe; transporting the produced prestressing steel and concrete composite pile to the field; and forming a punching hole having a predetermined diameter in the ground using an auger, and inserting the prestressing steel and concrete composite pile into the punching hole or inserting the prestressing steel and concrete composite pile into the ground by a pile driver. |
