Publication number: 20130272801Abstract: Since the distal backside is provided on a rear side of a wing edge in an entering direction, when a steel pipe pile is rotationally driven into the ground, the distal backside resists against the rotation moment with the wing edge at the center. Thus, while avoiding the off-centered movement of the steel pipe pile and ensuring linearity, the steel pipe pile can be penetrated into the ground. Further, since a slanted opening is provided at a front side of the wing edge in the entering direction, soil excavated in accordance with the rotational drive into the ground can be smoothly introduced into the steel pipe pile body through the slanted opening. Thus, while restraining the ground resistance in accordance with the entering, the soil introduced into the steel pipe pile body can be pushed upward, thereby reducing an increase in the penetration resistance caused by clogging within the pipe.Type: ApplicationFiled: July 9, 2012Publication date: October 17, 2013Applicant: NIPPON STEEL & SUMIKIN ENGINEERING CO., LTD.Inventors: Masamichi Sawaishi, Masatoshi Wada
