Further, to explain this with reference to an example shown in the drawings, the tip 3 of the pile body 2 of a desired pile, such as a steel pipe pile, an H-shaped steel pile, or a concrete pile, whose tip is formed into a pointed end 1. A spiral chisel blade or chisel screw 4 is provided, and screw pitches 6 are formed at the rear end with narrower intervals than the screw pitches 5 of the spiral chisel blade or screw 4 provided at the tip. It is provided with a pressure vane or a pressure screw 7. If necessary, intermediate blades 8 may be provided in the middle of the pile body 2 as shown in FIG. 2 to enhance the digging effect and to increase the supporting force of the pile after burial. The spiral blade can be formed very easily by cutting 10 one side of a doughnut-shaped steel plate 9 and fixing it to the pile body 2 under tension, as shown in FIG. Further, the spiral blade shown in FIG.
A blade with a small resistance can be formed by fixing the same cut part below the pile body 2. In the figure, reference numeral 12 is the lower supporting stratum, 13 is the intermediate supporting stratum, and 14 is the ground surface. It is preferable that the pitch diameter of the pressure impeller is one-half or less of the pitch diameter of the chisel impeller.

Since the present invention is constructed as described above, the pile body 2 can be rotated by attaching the tip 1 to the ground surface 14 and supporting it upright on a construction machine or other desired rotation device having a rotation device such as an earth auger or a drill piler. Due to the helical chisel blade or screw 4 and the pile body 2's own weight, it is naturally buried in the ground like a screw nail, and the excavated soil is placed at the rear end of the pile body 2. Not only does it have the effect of killing two birds with one stone by filling it with the pressure impeller 7 with a small pitch diameter and reburying it at the same time, but also has the extremely remarkable effect of being able to perform pollution-free burial with almost no noise since no concrete is poured. This is something that can occur.
