PROBLEM TO BE SOLVED: To provide a connection method for a foundation pile for housing, which enables steel pipes to be easily and surely connected together on a job site without the need for welding work.SOLUTION: A tapered pipe expansion part 4, which has both surfaces provided with through-holes 7, is preformed at an end of one steel pipe 1, and a tapered pipe contraction part 3, which is formed at an end of the other steel pipe 2, is pressed into the inside of the pipe expansion part 4 and connected. Subsequently, a drill makes a hole drilled in the inside pipe contraction part 3 from each of the through-holes 7. After that, a bolt 6 is inserted between the through-holes 7 and 7 and fastened. |
