PROBLEM TO BE SOLVED: To provide a pile construction technology capable of easily and largely reducing construction manhours by strengthening tip bearing power. SOLUTION: An H-shaped cross-sectional pile 4 is composed of a web 4a and flanges 4b and 4b, and its tip is composed of a base body part 5a composed of a plate-like body and two opening-closing parts 5b and 5b, and an area expanded member 5 of connecting both of these by a shaft pin 5c is fixed and arranged. A cap 5d is fixed to the tip of the opening-closing parts 5b and 5b, and the base body part 5a of the area expanded member 5 is formed in a substantially U shape formed of a combination of right/left pieces for covering both surfaces of the tip 4c of the web 4a of the pile 4, and the shaft pin 5c is fitted in its bottom part, and is connected to the opening-closing parts 5b and 5b. The base body part 5a of the area expanded member 5 composed of substantially rectangular right/left pieces 5a1 and 5a2, is arranged by extending its other end up to an upper part of the pile 4 along an obverse/reverse surfaces of the web 4a by fixing one end of wires 6 and 6 (a steel wire) by interposing and fixing the tip 4c of the web 4a between these right/left pieces 5a1 and 5a2.
