PURPOSE: A construction method of a spiral steel pipe pile is provided to stably support a foundation structure by reducing the relaxation of a steel pipe pile through a reinforcing layer. CONSTITUTION: A construction method of a spiral steel pipe pile is as follows. A spiral steel pipe pile(1) is inserted into the ground at a required depth. A bore(2), which is to be filled with a reinforcing material, is formed on the ground around the top edge of the spiral steel pipe pile using an auger drill. A reinforcing layer(3) is formed by filling the bore with concrete or mortar. The spiral steel pipe pile is connected to the adjacent spiral steel pipe pile through a coupler. |
