SCREW ANCHOR PILE FOR EARTH REINFORCEMENT AND MANUFACTURING METHOD FOR THE SAME

摘要

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 bit 500 and 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.

1. A screw pile for reinforcing the ground, comprising:
a bar-shaped body 100 with a pile hole 110 that is a passage of air and grouting solution; a screw 200 that is formed spirally and integrally around the body 100; one or more grouting holes 300 formed around the body 100 so that grouting solution can be sprayed; a tip expanding-reinforcing plate 400 that has a plate shape, is coupled to one end of the body 100 on its top, and has an air discharge hole 410 formed through the top and the bottom in the same line as the pile hole 110; and an excavation bit 500 that has one end coupled to a side of the bottom of the tip expanding-reinforcing plate 400 and the other end with a blade, wherein when the bit 500 and the screw 200 form a hole in the ground by rotation and the tip expanding-reinforcing plate 400 moves to the bottom of the hole and performs grounding, thereby increasing a tip support force.
