To provide the embedding construction method for steel pipe piles by which the steel pipe piles inserted into a drilled pit are inserted smoothly and efficiently, without requiring large thrust, while the displacement of the pile cores of the steel pipe piles can be corrected simply and the height of the pile heads of the steel pipe piles can be arranged.
A casing 1 and an auger screw 5 housed in the casing 1 are rotated mutually in reverse, while a ground is excavated, pouring cement milk into the ground and a drilled pit is formed, and rich-mix foot-protection cement milk is poured into a stratum layer in length in twice or more as large as the diameters of the steel pipe piles from the front end of the auger screw 5, when the front end of the auger screw 5 reaches into the aimed stratum layer. The casing 1 and the auger screw 5 are extracted from the drilled hole, the steel pipe pile 3 in which flat pliers 8 are connected detachably at an upper end is inserted into the drilled pit, so that the front end of the pile 3 reaches a foot protection, and the steel pipe pile 3 can be embedded into the ground by removing the flat pliers 8 from the steel pipe pile 3, after the level of a pile head and a pile core or the like are adjusted by the section of the flat pliers 8 and apter the fixed time in the steel pipe pile is elapsed.
