Pile, pile installation jig, installation method of the pile, and solar power generation system using the pile

摘要

When a pile installation jig (41) is driven deeper by the length of grooves (15a), (15b) in a pile main body (12), abutment edges (42a) of notches (42) in arms (41d), (41e) push a plate-like member (13) and cause displacement of the plate-like member (13) along the grooves (15a), (15b). Thereby, the plate-like member (13) is held at portions in the grooves (15a), (15b) where the grooves (15a), (15b) extend in a direction transverse to a longitudinal direction of the pile main body (12).
