PROBLEM TO BE SOLVED: To solve the problem of conventionally causing unnecessary auxiliary work by settling of a support pile in an excavation hole. SOLUTION: The support pile 20 is inserted into the excavation hole 10 excavated in the substantially vertical direction from the ground surface. When fixing the support pile 20 in the excavation hole 10 by pouring cement milk into the excavation hole 10, a steel pipe 30 is fixed to a lower end part of the support pile 20, and the lower end 31 of the steel pipe 30 is allowed to abut on a bottom surface 11 of the excavation hole 10. As a result, the support pile 20 is held in the specific height from the bottom surface 11 by the steel pipe 30. Even if there is occurrence of various causes like settling the support pile 20 in the cement milk, the support pile 20 is not settled. COPYRIGHT: (C)2007,JPO&INPIT
