PILE BODY CONSTRUCTION METHOD
PROBLEM TO BE SOLVED: To provide a pile body construction method capable of shortening a provisional holding time on a gantry or omitting provisional holding while preventing downward stoppage of the pile body, and capable of reducing the construction cost and minimizing construction work with a yard.SOLUTION: A pile body construction method comprises a piled hole forming step of forming a piled hole 10 which is a piled hole 10 along a vertically downward direction from a construction surface and filled with a cement hardened body, a pile body insertion step of inserting a pile body 20 on which a bag-shaped body 50 is installed into the piled hole 10, after the pile body insertion step, and an injection step of injecting an injection material into the bag-shaped body 50 and blocking at least a part of the piled hole 10 by the bag-shaped body 50 to suppress the flow of the cement hardened body in the piled hole 10.SELECTED DRAWING: Figure 1
【課題】杭体の下げ止まりを防止しつつ架台での仮保持時間を短縮又は仮保持を省略でき、かつ施工コストの低減、及び最小限の施工ヤードでの施工が可能な杭体施工方法を提供すること。【解決手段】杭体施工方法は、施工面から鉛直下方向に沿った杭孔１０であって、セメント硬化体が充填された杭孔１０を形成する杭孔形成工程と、袋状体５０が設置された杭体２０を杭孔１０に挿入する杭体挿入工程と、杭体挿入工程の後に、袋状体５０に注入材を注入して袋状体５０により杭孔１０の少なくとも一部を封鎖することによって、杭孔１０内でのセメント硬化体の流動を抑制する注入工程と、を備える。【選択図】図１
