STEEL PIPE PILE CUTTING DEVICE AND STEEL PIPE PILE CUTTING METHOD
To provide a steel pipe pile cutting device and a steel pipe pile cutting method which can cut a steel pipe pile with a variable inner diameter at a predetermined depth position.SOLUTION: A pile 2 is cut by a steel pipe pile cutting device 3 which has a main shaft 4 inserted inside a pile 2, an arm 5 for fixation which is provided at the lower part of the main shaft 4 and is stretchable in a radial direction of the pile 2, an arm 6 for a cutting machine which is provided at a lower part of the main shaft 4, and a cutting machine 7 provided at the tip of the arm 6 for the cutting machine. The arm 6 for the cutting machine is stretchable in the radial direction of the pile 2, and is rotatable around the main shaft 4. The cutting machine 7 can jet high pressure water toward the inner surface of the pile 2.SELECTED DRAWING: Figure 2
【課題】内径が変化する鋼管杭を所定に深さ位置において切断することを可能とする鋼管杭切断装置および鋼管杭切断方法を提案する。【解決手段】杭２の内部に挿入される主軸４と、主軸４の下部に設けられて杭２の直径方向に伸縮可能な固定用アーム５と、主軸４の下部に設けられた切断機用アーム６と、切断機用アーム６の先端部に設けられた切断機７とを備える鋼管杭切断装置３により杭２を切断する。切断機用アーム６は、杭２の直径方向に伸縮可能であるとともに主軸４を中心に回転可能である。また、切断機７は、杭２の内面に向けて高圧水を噴射可能である。【選択図】図２
