JOINT STRUCTURE OF PILE HEAD SECTION AND CONSTRUCTING METHOD OF PILE

摘要

PROBLEM TO BE SOLVED: To provide a constructing method of a pile provided with a pile body having a joint structure of a pile head capable of forming a high strength at a low cost and having a good workability in a simple constitution. SOLUTION: A radially widening member 2 is provided in the head of a steel pipe 1a, The steel pipe 1a is fixed to the upper part of a cage 17a constituting a cast-in-place concrete pile 17 and erected in a pile hole 12 in a base ground 11. Concrete 22 is placed in the pile hole 12 so as to embed the cage 17a and the cast-in-place concrete pile 17 forming a lower pile structure is constructed. A peripheral setting liquid 14 is injected in the gap between the steel pipe 1a and hole wall. Concrete 22 is charged in the steel pipe 1a to construct a pile body 1 forming the super structure. The periphery of the pile body 1 is excavated to form a foundation bottom face 13. Thereafter, anchor members are disposed. The other end 3b of the anchor member is embedded in the foundation horizontal member or the superstructure or the like , a joint structure with the foundation horizontal member or the superstructure or the like is formed at the pile head of the pile body 1.
