PROBLEM TO BE SOLVED: To provide a hybrid pile device and a method for holding strength even to a water level variation in the ground, by covering a wooden pile with a fluid solidification material having a uniform thickness, while excavating an excavation hole of the ground in a designed size of an optional design position.SOLUTION: A hybrid pile device forms a pile insertion cylindrical body of providing a clearance between an outer cylinder inner wall and the wooden pile outer periphery, by inserting the wooden pile of connecting-fixing a closed top body to the lower end, from a lower end opening of a vertically long hollow outer cylinder. A covering part of the wooden pile is formed in a total length peripheral shape by inputting a fluid solidification material in the clearance between the outer cylinder and the wooden pile in a state of pushing-down/pressing the pile insertion cylindrical body in the ground. After inputting the fluid solidification material in the clearance between the outer cylinder and the wooden pile, the outer cylinder is pulled out upward from the underground, and a hybrid pile built-in structure of the wooden pile and the covering part is constructed.SELECTED DRAWING: Figure 1 |
