description The invention provides a photovoltaic support screw pile with vertical fins and a using method.The screw pile comprises a steel sleeve, a spiral steel pile steel pipe, spiral steel pile blades, a vertical limiting check ring and a plurality of vertical fins, and the spiral steel pile steel pipe is provided with the multiple spiral steel pile blades in the length direction; a steel sleeve is arranged between every two adjacent spiral steel pile blades, the vertical fins are arranged on the outer wall of the steel sleeve, vertical limiting check rings are arranged at the upper end and the lower end of the steel sleeve, and the spiral steel pile steel pipe is sleeved with the steel sleeve and the vertical limiting check rings. The spiral steel pile steel pipes above and below the steel sleeve welded with the vertical fins are respectively provided with a group of limiting gears, so that pressing-in during pile forming is facilitated, pulling-out during pile pulling is also facilitated, and the overall constructi
