READY-MADE PILE WITH IMPROVED PILE HEAD, PILE FOUNDATION STRUCTURE AND STRUCTURE OF TWO OR MORE KINDS OF PILE AND FOUNDATION

摘要

PROBLEM TO BE SOLVED: To provide a ready-made pile with an improved pile head, the pile enabling smoothing of the bending moment generated in multiple entire piles under the foundation by being disposed in an intense part of axial force variation especially in an earthquake and improved in a pile head, and a pile foundation structure comprising this ready-made pile with the improved pile head and the concrete foundation, and further a structure of two or more kinds of pile and foundation comprising a general ready-made pile, the ready-made pile with the improved pile head and the foundation.;SOLUTION: A ready-made pile with an improved pile head 10 comprises a ready-made pile 1 and a pile head member 2 with a lower end fixed in a pile head upper end of the ready-made pile 1. The pile head member 2 exhibits a truncated cone where the diameter of a lower end coming into contact with the pile head upper end is the largest and the diameter is reduced as being separated from the pile head to become a diameter less than the pile diameter.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2017,JPO&INPIT
