PILE CONSTRUCTION JIG AND ROTARY PILE
PROBLEM TO BE SOLVED: To provide a pile construction jig with a simple structure, which can be easily attached to a rotary pile and rotate the rotary pile to penetrate into the ground, and the rotary pile constructed by this pile construction jig.SOLUTION: A pile construction jig 1 rotates a rotary pile 100 with a tubular shaft part 101 to penetrate into the ground and has an outer split piece 10, which is split into multiple pieces in circumferential direction of the shaft part 101, to form a tubular member as a whole. The pile construction jig 1 comprises: an exterior body 5, which covers the shaft part 101 from outside and can contact to the shaft part 101; a fastening part 6 giving a fastening force F1 to fasten the outer split piece 10 with each other in a direction to come close; convex parts 7, which are unified with the outer split piece 10 on outer face 10b of the outer split piece 10, protrudes outward in a radial direction of the shaft part 101 at a part of the circumferential direction of the shaft part 101 and receives a rotative force from the construction device to rotate the rotary pile 100 to penetrate into the ground.
【課題】簡易な構造で、回転杭に容易に取り付けることができ、回転杭を回転貫入することが可能な杭施工治具、及び、この杭施工治具によって施工される回転杭を提供する。【解決手段】管状をなす軸部１０１を有する回転杭１００を、地盤に回転貫入する杭施工治具１であって、軸部１０１の周方向に複数に分割された外側分割片１０を有して全体で管状の部材を形成するとともに、軸部１０１を外側から覆って軸部１０１に接触可能な外装体５と、外側分割片１０同士を互いに近接する方向に締め付ける締付力Ｆ１を付与する締結部６と、外側分割片１０の外面１０ｂに外側分割片１０と一体に設けられ、軸部１０１の周方向の一部で軸部１０１の径方向外側に向けて突出し、回転杭１００を回転貫入させる施工装置からの回転力を受けるコマ部７と、を備えている。【選択図】図２
