<P>PROBLEM TO BE SOLVED: To prematurely remove a construction machine for foundation pile construction from a constructed foundation pile, in a foundation pile construction method for inserting a foundation pile into a construction hole in which a fluid material hardened with elapse of time is contained by the construction machine for foundation pile construction. Ž<P>SOLUTION: A first fluid material 6 formed by mixing a foundation consolidation fluid and sediment and a second fluid material 7 formed by mixing a pile periphery consolidation fluid and sediment are contained in the construction hole 5 for the foundation pile. The construction unit 17 of an earth auger 10 inserts an extension foundation pile 33 having a cap 40 for rotation on the pile head to a predetermined depth. A cap 50 for connection is attached to the cap 40 for rotation. An excavator 60 having a hydraulic shovel 61 supports the extension foundation pile 33 to a predetermined height through the cap 50 for connection until the first fluid material 6 and the second fluid material 7 are hardened to a predetermined strength.
