PROBLEM TO BE SOLVED: To provide a pile head treatment method capable of easily and reliably chipping a pile extra fill portion to small pieces after breaking the pile head during a pile head treatment.SOLUTION: The pile head treatment method is to perform a head treatment on a cast-in-place concrete pile, the method including: a laterally breaking step on a pile head extra fill 21 of a pile head; a separating step to separate the laterally beaked pile head extra fill from the pile head; a boring step to vertically bore a powder charge hole 50 from an upper surface of the separated pile head extra fill; a loading step to load a powder charged holder 40 vertically extending in a star-like polygon sectional view into the powder charge hole; and a chipping step to chip the pile head extra fill to small pieces with a kinetic crushing agent contained in the powder charged holder.SELECTED DRAWING: Figure 4
【課題】杭頭処理において破断後の杭頭余盛部を簡単かつ確実に小割可能な杭頭処理工法を提供する。【解決手段】この杭頭処理工法は、場所打ちコンクリート杭の杭頭処理を行う工法であって、杭頭部の杭頭余盛部２１を水平破断する工程と、水平破断された杭頭余盛部を杭頭部から分離する工程と、分離された杭頭余盛部の上面から装薬孔５０を縦方向に削孔する工程と、断面形状が星型多角形で縦方向に延びる装薬ホルダ４０を装薬孔に装填する工程と、装薬ホルダに収容された動的破砕剤により杭頭余盛部を小割破砕する工程と、を含む。【選択図】図４
