PILE DRIVING METHOD AND PILE DRIVING DEVICE USED THEREFOR

摘要

PROBLEM TO BE SOLVED: To provide a pile driving method and a shaft excavating device used therefor capable of driving a vertical pile of a deep depth, by suspending and supporting a scaffold without requiring a large scull and a large hoisting machine. SOLUTION: This pile driving method performs excavation work by the scaffold 20 liftably suspended and supported in a predetermined range by a hoising machine 12 by fixing a moving base 10 having the hoising machine 12 in the middle of the vertical pile 2; and advances excavation by downwardly moving a fixing position of the moving base 10 in response to the advance of the excavation by upwardly retreating the scaffold 20 by the hoising machine 12 in blasting.
