CAST-IN-PLACE CONCRETE PILE CONSTRUCTION METHOD AND CAST-IN-PLACE CONCRETE PILE
To provide a cast-in-place concrete pile construction method capable of excavating holes for expanded bottom piles and connecting piles adjacent to each other with the same excavator, capable of efficiently and economically constructing expanded bottom piles consisting of multiple expanded bottom piles and connected piles, and a cast-in-place concrete pile.SOLUTION: A ground improvement body 15 is formed by improving the ground G of a pair of adjacent expanded bottom piles 1 or the ground G of a connecting pile 8. Preliminary excavation using an excavator 9 for piles is performed to form an excavation hole 10 in the ground G of the connected pile 8 where the ground improvement body 15 is not formed or the ground G of a pair of adjacent expanded bottom piles 1. A continuous excavation hole is formed by communicating with the excavation hole 10 formed in the preceding excavation while forming an excavation hole 11 by the subsequent excavation using the pile excavator 9 and guiding the ground G of the pair of adjacent expanded bottom piles 1 forming the ground improvement body 15 or the ground G of the connecting pile part 8 in the vertical direction with the ground improvement body 15.SELECTED DRAWING: Figure 1
【課題】隣り合う拡底杭部と連結杭部の掘削孔を同じ掘削機で掘削形成することを可能にし、効率的且つ経済的に複数の拡底杭部と連結杭部からなる拡底杭を構築可能な場所打ちコンクリート杭の構築方法及び場所打ちコンクリート杭を提供する。【解決手段】隣り合う一対の拡底杭部１の地盤Ｇ、あるいは連結杭部８の地盤Ｇを地盤改良して地盤改良体１５を形成する。地盤改良体１５を形成していない連結杭部８の地盤Ｇ、あるいは隣り合う一対の拡底杭部１の地盤Ｇを、杭用の掘削機９を用いて先行掘削して掘削孔１０を形成する。地盤改良体１５を形成した隣り合う一対の拡底杭部１の地盤Ｇ、あるいは連結杭部８の地盤Ｇを、杭用の掘削機９を用いるとともに地盤改良体１５で鉛直方向に案内しながら後行掘削して掘削孔１１を形成しつつ先行掘削で形成した掘削孔１０と連通させて連通掘削孔を形成する。【選択図】図１
