PILE, TOOL FOR PILE INSTALLATION, INSTALLATION METHOD FOR THE PILE, AND PHOTOVOLTAIC POWER GENERATION SYSTEM USING THE PILE

摘要

PROBLEM TO BE SOLVED: To provide a pile that has high pull-out strength and bearing capacity of a pile body with a simple constitution.SOLUTION: When only a tool 41 for installation is driven deeper by the length of each of groove holes 15a, 15b of a pile body 12, a push contact side 42a of a cut part 42 of each of arm parts 41d, 41e pushes down a plate-like member 13, which moves along the groove holes 15a, 15b. Therefore, the plate-like member 13 moves in a longer direction of the pile body 12 along the groove holes 15a, 15b, then moves in a direction crossing the longer direction, and further abuts on a lower end of the groove holes 15a, 15b to stop. Consequently, the plate-like member 13 is held by a region extending in a direction (a horizontal direction or an inclined direction close to the horizontal direction) crossing the longer direction of the groove holes 15a, 15b, namely, the region nearby the lower end of the groove holes 15a, 15b to be supported.
