EMBEDDING METHOD FOR READY-MADE PILE

摘要

PROBLEM TO BE SOLVED: To increase a vertical load that can be borne by one pile by transmitting the load to the original ground from recessed and projected portions near the tip portion of the ready-made piles without generating a great amount of excavated slurry. SOLUTION: Excavated bore hole is made at a pile main body portion and an enlarged bottom portion. Within the excavated bore hole, a ready-made pile having ring-shaped recessed and projected portions at the tip portion is lowered and cement milk is filled. The ring-shaped recessed and projected portions are arranged inside the enlarged bottom portion of the excavated bore. When a vertical load acts to the ready-made pile, the load is transmitted at the peripheral edge of the ring-shaped recessed and projected portions of the ready-made pile.
