PROBLEM TO BE SOLVED: To provide a precast pile embedding method capable of increasing an end bearing capacity and a peripheral surface frictional force and improving an extraction resistance force of a precast pile by strongly integrating a drilled hole and embedded precast pile.SOLUTION: In a precast pile embedding method, soil cement formed around a base part of a precast pile in a drilled hole is expanded by adding a bloating agent having expanding effect in a cement milk or mortar in advance.SELECTED DRAWING: Figure 1
【課題】掘削孔と埋設した既製杭を強固に一体化して、既製杭の先端支持力や周面摩擦力の増大及び引抜抵抗力の向上を図った既製杭埋込み杭工法を提供すること。【解決手段】セメントミルク又はモルタルには予め膨張作用を有する発泡剤を添加しておくことにより、掘削孔中の既製杭の基部周辺に形成したソイルセメントを膨張させる既製杭埋込み工法。【選択図】図１
