BURYING METHOD FOR READY-MADE PILE, FOUNDATION PILE STRUCTURE, AND READY-MADE PILE

Japanese Patent JP2005139900

A

To increase a supportive force of a pile by inserting and installing a ready-made pile, which has a bulged connection and a projection on the lower end thereof, in a widened bottom part of a pile hole filled with soil cement.

The pile hole having the widened bottom part is drilled, and cement milk is injected into the widened bottom part to form the soil cement that fills the widened bottom part, then the ready-made pile is anchored to the soil cement. The projection is formed on the lower end of the shaft of the ready-made pile, and a conically acting shearing force is transmitted from the lower face of the projection and of the pile so as to form a supportive surface on the ground surface at the bottom of the widened bottom part. The pile, therefore, is buried in the soil cement to have a predetermined gap across the lower end of the pile and the ground surface at the bottom of the widened bottom part.
