HOLDING DEVICE OF VIBRATION HAMMER, AND INSTALLATION METHOD OF STEEL PIPE PILE
PROBLEM TO BE SOLVED: To provide a holding device of a vibration hammer capable of holding a steel pipe by exerting pressing force only from one direction inside or outside of the steel pipe and without deforming the steel pipe, along with an installation method of a steel pipe pile using the same.SOLUTION: A holding device 1 of a vibration hammer VH is for holding a steel pipe P, and includes a head part 2, a support part 3 extending downward from an undersurface of the head part 2, and one or a plurality of pressing means 4 provided at one or a plurality of locations in the direction of extension of the support part 3 and generating pressing force in an outward or inward direction on an inner or outer surface of the steel pipe P. The pressing force is of a magnitude sufficient for generating frictional force that can fix the steel pipe P at a time of driving or pull-out by the vibration hammer VH. Furthermore, a location of pressing by the pressing means 4 on the steel pipe P is in an intermediate region in a lengthwise direction of the steel pipe P, so as not to cause deformation by the pressing force.SELECTED DRAWING: Figure 1
【課題】鋼管の管内又は管外の一方のみから押圧力を及ぼして鋼管を把持することができかつ鋼管の変形を生じないバイブロハンマの把持装置及びこれを用いた鋼管杭の施工方法を提供する。【解決手段】鋼管Ｐを把持するためのバイブロハンマＶＨの把持装置１であって、ヘッド部２と、ヘッド部２の下面から下方に延在する支持部３と、支持部３の延在方向の１箇所又は複数箇所に設けられ鋼管Ｐの内面又は外面に対し外向き又は内向きに押圧力を発生可能な１又は複数の押圧手段４と、を有し、押圧力はバイブロハンマＶＨによる打込み又は引抜きの際に鋼管Ｐを固定可能な摩擦力を生じる大きさであり、かつ、押圧手段４が鋼管Ｐを押圧する位置は、押圧力による変形を生じない、該鋼管Ｐの長さ方向の中間領域にある。【選択図】図１
