OPEN ENDED STEEL PIPE PILE FOR ROTATINGLY JACKING AND ROTATINGLY JACKING METHOD FOR OPEN ENDED STEEL PIPE PILE

摘要

PROBLEM TO BE SOLVED: To provide a steel pipe pile easily constructible and having excellent economic efficiency and a rotatingly jacking method for the steel pipe pile as an auxiliary construction method for suppressing a penetration resistance when rotatingly jacking a steel pipe pile for building structures and steel pipe bracing type retaining walls. SOLUTION: In this open ended steel pipe pile for the foundation or steel pipe bracing type retaining walls of a civil engineering and building structures, a pipe for fluid supply is disposed downward from the upper end of the steel pipe pile along the inner wall of the steel pipe pile. The lower end of the pipe extends from the lower end of the steel pipe pile to a pipe inside soil clogging start position on the upper side of the lower end of the pipe. Nozzles for fluid discharge are disposed in the pipe at one or two positions between the lower end of the pipe and the pipe inside soil clogging start position so that a fluid can be discharged in the circumferential direction along the inner wall of the steel pipe pile.
