PROBLEM TO BE SOLVED: To provide a ready-made pile burying construction method capable of efficiently compacting a filler with a simple structure, and capable of facilitating top end control and centering of a ready-made pile. SOLUTION: This ready-made pile burying method builds up the ready-made pile 4 in an excavated excavation hole 2, and fills and compacts the filler 3 in a clearance part between the built-up pile 4 and an excavation hole wall, and has a process of pushing in the pile tip of the pile 4 up to the expected depth vicinity while rotating in the screwing-in direction of an agitating blade 52 by fitting a compacting casing 5 around the pile 4 built in the excavation hole 2 by using the compacting casing 5 for projecting the spiral agitating blade 52 on an outer peripheral surface of a cylindrical casing body 51, and projecting a pressing plate 53 inclining in the same direction as the agitating blade on a tip part outer peripheral surface of the casing body 51, and a process of inputting the filler 3 such as slag, gravel, and a crushed stone from aboveground part to a clearance part between the pushed-in compacting casing 5 and the excavation hole wall, and compacting the filler 3 of a tip part of the compacting casing 5 while pushing in the filler 3 by an inclined face of the pressing plate 53 by periodically or intermittently pushing down the casing while inversely rotating and gradually pulling up the compacting casing 5.
