PILE CONSTRUCTION METHOD AND PILE
To provide a pile construction method and a pile capable of constructing a hardened foot part in a desired state.SOLUTION: A pile construction method comprises a step of injecting a first fixing liquid mixed with an expansive material into a pile hole provided in the ground, stirring and mixing with excavated soil, and constructing a pile peripheral part with this stirred and mixed first mixed material, a step of stirring and mixing the excavated soil and a second fixing liquid while pushing up the first mixed material by injecting the second fixing liquid into a bottom of the pile hole, and constructing a hardened foot part at the bottom of the pile hole with this stirred and mixed second mixed material, and a step of sinking prefabricated piles into the pile peripheral part and the hardened foot part.SELECTED DRAWING: Figure 2
【課題】根固め部を所望する状態に築造することができる杭の施工方法及び杭を提供すること。【解決手段】杭の施工方法は、地盤に設けた杭穴に膨張材を混ぜた第１の固定液を注入して掘削土砂と撹拌混合し、この撹拌混合した第１の混合材による杭周面部を築造する工程と、杭穴の底部に第２の固定液を注入することで第１の混合材を押し上げながら、掘削土砂と第２の固定液を撹拌混合し、この撹拌混合した第２の混合材による根固め部を杭穴の底部に築造する工程と、杭周面部及び根固め部に既製杭を沈設する工程と、を有する。【選択図】 図２
