PURPOSE:To exactly hold a pile by a method in which the upper end of a pile is held by a catching cap and hung down, and under a condition that levers symmetrically and radially provided to a holder are expanded on the ground's surface, the pile is held. CONSTITUTION:The catching cap 2 of a pile holder is coupled with the coupling piece 1a of a pile 1. Levers 4 are expanded by a lever lifter 8 and contacted with the oblique end face 7a of a holder metal 7 on the ground's surface, and under that condition the pile 1 is vertically held. |
