The invention provides a device for precision positioning of a pedal steel chisel pore-forming pile point, a manufacturing method and a using method. The device comprises a steel chisel, an ash filling barrel and a hopper, the steel chisel comprises a chisel body, a chisel head, a pedal and a level gauge, the chisel head is located at the lower end of the chisel body and in a cone shape, the pedal is located below the chisel body, and the level gauge is located at the top of the chisel body; the ash filling barrel comprises a hollow barrel body and an ash filling barrel handle located on the upper part of the barrel body, the barrel body sleeves the chisel body, the inner wall of the barrel body is attached to the outer wall of the chisel body, and the length of the barrel body is smaller than the distance from the chisel head to the pedal; the outer diameter of the lower end of the hopper is smaller than the inner diameter of the barrel body, lime can be grouted into soil in 20 cm-50 cm, instead of only scattering on the surface of the soil, when operation is conducted around and the positioning point close to a mark is covered, the covering soil can be wiped out, the marking point position can be exposed by wiping a little more soil, the hole is small, ash filling is less, positioning is accurate, deviation is not prone to occurring, the original positioning point is easy to find, time and labor are saved, and convenience and fastness are achieved.
