Title:
PILE WITH METAL FITTING
Document Type and Number:
Japanese Patent JP2017031783
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a pile which prevents that the soil in the ground intrudes into a pipe when piling a metal-made pipe pile, enables piling into the tough ground by improving rigidity, is not hindered in a piling direction by small stones or the like in the ground, and does not need a large force at piling work even if the side pressure of the pile in the ground is high.SOLUTION: By attaching a metal fitting to a tip part of a conventional metal-made pipe, the intrusion of sand or the like into the pipe is prevented when piling a pile into the ground. Also, by attaching a conical metal fitting whose tip is formed flat by forging and quenching the tip part to a tip of the pile, rigidity is increased, and since a tip of the metal fitting is flat, the pile can be piled into a desired piling direction without being hindered by an obstacle such as small stones in the ground. Furthermore, by forming a ring-shaped portion which is larger than a diameter of the pile, side pressure applied from the inside of the ground can be alleviated.SELECTED DRAWING: Figure 1
