The present invention relates to a screw pile for ground reinforcement having a front end expanding reinforcement plate coupled thereto and, more particularly, to a pile for ground reinforcement capable of excavating the ground, comprising: a rod-shaped body having a through-hole formed therein so as to serve as a passage of air and a grouting liquid; a screw wing formed in a helical shape along the outer peripheral surface of the body and installed integrally on the body; multiple grouting holes bored on the outer peripheral surface of the body such that a grouting liquid can be sprayed; a front end expanding reinforcement plate having the shape of a circular plate, one end of the body being coupled to the upper surface thereof, an air discharge hole being bored to penetrate the upper and lower surfaces of the front end expanding reinforcement plate such that the same lies on a straight line together with the through-hole; and an excavation bit having one end coupled to one side of the lower surface of the front end expanding reinforcement plate, a cutting blade being formed on the other end thereof, wherein the excavation bit (500) and the screw wing rotate and perforate the ground, and the front end expanding reinforcement plate is then seated on the bottom surface of the bored hole and grouts the same, thereby increasing the front end support force. |
