PURPOSE: A piling method by combining a prestressed concrete pile and an anchor body is provided to improve the bearing force and structural stiffness of a pile and to obtain a high-quality pile with low expenses. CONSTITUTION: The piling method by combining a prestressed concrete pile and an anchor body comprises the steps of: installing a ready-made PHC pile(10) to the ground to have a hollow part; forming a perforated part by excavating to the preset last bearing layer by driving an excavator using an auger or a tipper through the hollow part of the PHC pile(10); interposing a steel bar(20) into the hollow part of the PHC pile(10) and the perforated part of the ground; and forming an anchor body(30) by placing concrete tightly into the perforated part and the hollow part.
