PILE DRIVING DEVICE, AND PILE DRIVING METHOD USING THE SAME
PROBLEM TO BE SOLVED: To provide a pile driving device and a pile driving method that enable low-noise pile driving work.SOLUTION: A pile driving device 19 includes fitting parts 20, 21 fitted to an arm tip of a construction vehicle, a vibration generator part 27 connected to the fitting parts 20, 21, a vibration transmission part 24 fitted on the vibration generator part 27 and having a spherical part 26 at a lower part thereof, and a press-in head fitted on the spherical part 26 of the vibration transmission part 24. The vibration generator part 27 includes a vibration generator mechanism that generates vibration in an axial direction of a pile, through rotation of an eccentric weight. The press-in head includes a recessed spherical part that surrounds the spherical part 26 so as to allow rotation around the direction of vibration generation, and a fitting recess provided at a lower part of the press-in head for supporting a top end of the pile while having the top end of the pile fitted detachably in the axial direction. The pile is pressed into a ground using vibration in the direction of vibration generation generated by the vibration generator part 27, while supporting the top end of the pile by the fitting recess.SELECTED DRAWING: Figure 2
【課題】低騒音の杭打ち作業が可能な杭打ち装置及び杭打ち方法を提供する。【解決手段】杭打ち装置１９は、建設車両のアーム先端に取付けられる装着部２０，２１と、装着部２０，２１に連結される振動発生部２７と、振動発生部２７に装着されて自身下方に球体部２６を有する振動伝達部２４と、振動伝達部２４の球体部２６に装着される圧入ヘッドとを備え、振動発生部２７は、偏心錘の回転によって杭の軸方向に沿った方向を振動発生方向とする振動を発生させる振動発生機構を有し、圧入ヘッドは、振動発生方向を軸とする回転を許容するように球体部２６を囲繞する凹球面部と、自身下部に設けられて杭の上端部をその軸方向に沿って着脱可能に嵌合させて支持する嵌合凹部とを有し、嵌合凹部で杭の上端部を支持しつつ、振動発生部２７で発生させた振動発生方向の振動を用いて杭を地中に圧入する。【選択図】図２
