JOINING STRUCTURE OF STEEL PIPE PILE

PROBLEM TO BE SOLVED: To provide a joining structure of a steel pipe pile requiring no welding at site, having excellent reliability, construction efficiency, and workability, requiring less number of parts forming a joined part, and enabling the easy machining of a joint part. SOLUTION: The end part 11 of a first steel pipe pile 1 comprises a plurality of projected parts 11a formed apart from each other in the circumferential direction so as to be projected in its axial direction. The end part 12 of a second steel pipe pile 2 is formed in a roughly complementary shape to the shape of the end part of the first steel pipe pile. A hole of a prescribed shape is formed between the projected parts 11a and 11b of the first and second steel pipe piles adjacent to each other when the end parts of these piles are fitted to each other, and the first steel pipe pile is connected to the second steel pipe pile through a pin member 13 inserted into the hole.
