Abstract
The present invention relates to a screw pile for reinforcing the ground, and in particular, a pile for reinforcing the ground which can dig the ground. The screw pile includes: a bar-shaped body with a pile hole that is a passage of air and grouting solution; a screw that is formed spirally and integrally around the body; one or more grouting holes formed around the body so that grouting solution can be sprayed; a tip expanding-reinforcing plate that has a plate shape, is coupled to one end of the body on its top, and has an air discharge hole formed through the top and the bottom in the same line as the pile hole; and a excavation bit that has one end coupled to a side of the bottom of the tip expanding-reinforcing plate and the other end with a blade, in which when the bitand the screw form a hole in the ground by rotation, the tip expanding-reinforcing plate moves to the bottom of the hole and performs grounding, increasing a tip support force.
