PROBLEM TO BE SOLVED: To stably support a pile body in all working processes when installing the pile body at a boundary point. SOLUTION: A hole 4 is excavated in a ground near a boundary point and the pile body 2 is inserted and placed in the hole 4. Supporting means 5 is mounted at the upper end of the pile body 2 for supporting the pile body 2 at its upper end. Then, sediment 6 is charged into the hole 4 and the charged sediment 6 is pressed together with the pile body 2 to be fixed at its lower end. The supporting means 5 is replaced right over the sediment 6 on the pile body 2 and fixed to the position. A mortar 7 is placed into the hole 4 and the supporting means 5 is embedded in the mortar 7. After the mortar 7 is solidified, the sediment 21 is charged into the hole 4 and pressed together.
