PROBLEM TO BE SOLVED: To provide a rotary pressing pile for sheet-like articles screwable into soil easily and securely by screwing even if the ground is hard, and, in the screwed state, capable of fixing a sheet-like article by stably pressing the sheet-like article on the ground surface.
SOLUTION: The center of the lower surface of a disk-shaped pressing plate 3 for pressing the sheet-like article 2 is a conical part 22 reduced downward in diameter, and a support post 6 projects downward from the lower end of the conical part 22. A helical projection 10 is provided at least on the lower side of the outer peripheral surface of the support post 6. A screw driver engagement hole 15 for inserting a front end engagement portion of a screw driver is disposed coaxially with the axis of the support post 6 in the center of the upper surface of the pressing plate 3.
