FITTING METHOD OF STEEL PIPE PILE WITH BLADE AND CASING DRIVER USED THEREFOR

摘要

PROBLEM TO BE SOLVED: To improve the fitting workability in the case a steel pipe pile with blades is fitted to a casing driver. SOLUTION: A support device 17 holding a steel pipe pile with blades and making it stand is arranged at the lower face of a rotary driving device 7 of the casing driver. The casing driver 1 is installed in the pile center, and the steel pipe pile with blades is forced to penetrate the chucking device 8 of the casing driver 1 to ground the blade part onto the ground. The steel pipe is supported by the support device 17 and a spacer 13 is interposed between the chucking device 8 and the steel pipe. The steel pipe pile with blades is held together with the spacer 13. In this way, the steel pipe pile with blades can be fitted to the casing driver without influence of the blades.
