Provided is a method for burying a precast pile in which an excavation hole and a buried precast pile are strongly integrated, the end bearing capacity and the circumferential surface frictional force of the precast pile are increased, and the extraction resistance strength thereof is improved. Provided is a method for burying a precast pile in which a foaming agent having an expanding effect is added to the cement milk or mortar in advance, whereby the soil cement formed around the base of the precast pile in the excavation hole is caused to expand. |
