PILE COLUMN AND CONSTRUCTION METHOD OF THE SAME

PROBLEM TO BE SOLVED: To provide a pile column which is low in cost and has both of functions of a pile and a column supporting a solar panel trestle which is installed on a ground and is strong also against a wind load causing a solar panel to be floated.SOLUTION: A pile column has both of functions of a pile and a column supporting a solar panel trestle which is installed on a ground. The pile column comprises a steel single pipe cut in a predetermined length and a first mounting member mounted to the steel single pipe. The first mounting member includes: a circular cylinder having an inner diameter slightly larger than an outer diameter of the steel single pipe; a substantially roll of doughnut-like spiral blade provided projectingly on an outer periphery of the circular cylinder; an induction hole formed for inserting a bar for positioning the pile column at the center of a bottom of the circular cylinder; and a drilling blade provided projectingly on a lower end of the bottom of the circular cylinder.
