Claims

[Scope of Claim for Utility Model Registration] An expanded bottom pile that is made by placing a reinforcing bar cage or a ready-made pile in a hole that is excavated into the ground and has an enlarged bottom part at the tip, and pouring concrete, etc. inside and outside of the hole, or the ready-made pile. 1. A structure for reinforcing the tip of an expanded bottom pile, characterized in that a plurality of reinforcing members each having a reinforcing plate attached to the tip of a bar are inserted into the pile, and the reinforcing plates are arranged in the expanded bottom portion.
