Summary:PROBLEM TO BE SOLVED: To provide a pile top processing method capable of reducing cost for processing the pile top and carrying out safely the work as compared with conventional cases. SOLUTION: A cage cylindrically formed of a plurality of pile main reinforcements and a plurality of circularly formed hoops is inserted in a vertical hole formed in the ground and concrete is placed to construct a pile. A protection member is put on the upper outer peripheral face of the pile main reinforcements of the cage and further, a winding member is put on the upper outer peripheral face of the cage and the cage is inserted in the pile hole to fully place concrete in the hole and further form an extra fill in the outside and inside of the upper part of the cage. After the concrete has cured, the concrete at the outside of the winding member of the upper part of the cage is removed and thereafter, the winding member is removed and finally the extra-fill part in the upper part of the cage is removed together with the protection member.
