The present invention relates to a screw anchor pile used when the ground is drilled. According to the present invention, the screw anchor pile comprises: a rod part having a hollow hole inside and a grouting hole on the outer circumference surface; a blade part formed in a spiral form in the longitudinal direction of the outer circumference surface of the rod part; and a head part which includes a head wherein a discharge hole is penetrated and formed in the bottom, and bits combined with right and left sides of the head respectively and is combined with the front end of the rod part. The width of the blade part and the right and left width of the head part are the same. Therefore, the blade part can not be damaged when the ground is drilled. Moreover, as the integrated head is used, the number of welding can be reduced, thereby reducing costs for manufacturing a screw pile. |
