Abstract

PURPOSE: To better the load transmission between the steel pipe and a bell section formed therebelow by fixing a deformed bar on the bottom of the lower end of the steel pipe.
CONSTITUTION: An expanded hole 2 is formed below a cylindrical hole 1 by excavation. On the other hand, the upper portion of a plurality of deformed bars 7 are connected firmly together to the steel bottom plate 6 fixed at the lower end of the steel pipe 5 to form a steel pile body 8. The pile body 8 is inserted into the cylindrical hole 1 and grouting material 9 is injected under pressure into a clearance formed by the bottom plate 6 and the expanded hole 2 through an impregnating pipe 17 to build a bell section having the deformed bar 7 imbedded with the grouting material. This facilitates the formation of the bell section made up of the grouting material of high quality, while improving the interlocking force between the deformed bar 7 and the grouting material 7.
