Title:
SCREW PILE AND BURYING METHOD THEREOF
Document Type and Number:
Japanese Patent JP2015113563
Kind Code:
A
Abstract:
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 capacity of the screw pile A even more.
