PENETRATION ASSISTING JIG AND STEEL PIPE PENETRATION METHOD
To efficiently penetrate a core material into an underground hole filled with a filling material.SOLUTION: A penetration assisting jig for penetrating a core material into an underground hole filled with a filling material includes a rod connector connected to a rod capable of selectively applying a rotational force about an axis, a vibration, or both a rotational force and a vibration. The rod connector is provided with a notch for engaging a protruding member attached to the core material.SELECTED DRAWING: Figure 1
【課題】芯材を充填物で満たされた地中孔に、効率よく貫入することである。【解決手段】充填物で満たされた地中孔に芯材を貫入するための貫入補助治具であって、軸心まわりの回転力、または振動、もしくは回転力と振動の両者を選択的に作用させることの可能なロッドに接続されるロッド接続具を備え、該ロッド接続具に、前記芯材に取り付けた突状部材を係止する切欠き部が、設けられている。【選択図】図１
