PROBLEM TO BE SOLVED: To provide a screw pile that offers even greater bearing capacity. ! SOLUTION: A screw pile A comprises a hollow pile body 10 having a tip shaped like a pointed end of a cone, a spiral plate 13 installed spirally around the outer periphery of the tip side of the pile body 10, a first pile 1 installed on a side of the pile body 10 and has a through-hole 14 leading to the hollow part and an opening 11 for injecting cement milk into the hollow part, and a second pile 2 arranged in a way that may protrude from a side of the first pile 1. The second pile 2 also has a through-hole 24 leading to the hollow part of the first pile 1. When the screw pile A is buried, cement milk injected into the hollow part 12 is discharged into the ground from the through-holes 14 and 24. This solidifies the soil and forms a solidified lump integrated with the first pile 1 and the second pile 2. The solidified lump is formed to spread out on the lateral side of the first pile 1, thereby enhancing the bearing |
