To provide a burying method of steel pile possible of efficiently burying a steel pile that improves the corrosion resistance of the ground surface susceptible to corrosion while improving the durability of the pile foundation of a structure using the steel pile cost-effectively.SOLUTION: After embedded the steel pile 2 that includes the anticorrosion layer 6 on the outer surface, a ground surface area 3 of a predetermined length area is set so as to sandwich a part that penetrates the ground surface. A coating layer 4 including the FRP layer 4b is formed over the ground surface area 3, and after the coating layer 4 is cured, the steel pile 2 is embedded until the middle position 3a in the vertical direction of the ground surface area 3 reaches the ground surface GL.SELECTED DRAWING: Figure 1 【課題】腐食しやすい地表面部分の耐食性を向上させた鋼杭を能率良く埋設することができ、鋼杭を用いた構造物の杭基礎の耐久性を経済的に向上させることを課題としている。【解決手段】外表面に防食層６を備えた鋼杭２の埋設された後に地表面を貫通する部分を挟む所定長の領域となる地表面領域３を設定し、地表面領域３にＦＲＰ層４ｂを含む被覆層４を設け、被覆層４の硬化後に地表面領域３の上下方向の中間位置３ａが地表面ＧＬに達するまで鋼杭２を埋設する。【選択図】図１
