PROBLEM TO BE SOLVED: To provide a construction method for a pile capable of exhibiting big bearing capacity by using a prefabricated pile and making positioning of the pile by small energy. SOLUTION: The front end shoe 2 is installed in the lower end section of a pile body 1 of the hollow prefabricated pile to make positioning of the pile. The front end shoe 2 is separated from the pile body 1, a rod 7 passing through a hollow section of the pile body 1 is connected to the front end shoe 2, and the front end shoe 2 and the pile body 1 are buried in the ground while rotating the front end shoe 2. Gaps C and H or an opening section G are provided between the pile body 1 and a tubed part 5 of the upper part of the front end shoe 2, and the pile body 1 is positioned while taking earth and sand in the hollow section. When it reaches a supporting layer S, or when it approaches the supporting layer S, the pile body 1 is sat on a mounting section 3 of the front end shoe 2, and the positioning of the pile is continued in a state to cut off a flowing course of soil. When it reaches a predetermined depth, the rod 7 is pulled out to collect. COPYRIGHT: (C)2005,JPO&NCIPI
