The present invention relates to a ground reinforcement screw pile with a front end extension reinforcement plate mounted thereon. More specifically, the ground reinforcement screw pile excavates the ground, and comprises: a body of a bar shape having a through hole which is formed therein and becomes a passage of grouting liquid; a screw wing formed in a spiral shape along an outer circumferential surface of the body and integratively installed on the body; a plurality of grouting holes drilled to spray the grouting liquid to the outer circumferential surface of the body; a front end extension reinforcement plate of a circular plate shape wherein one end of the body is mounted on an upper surface thereof, and an air discharge hole penetrates the upper and a lower surface thereof to be placed on a line with the through hole; and an excavation bit wherein a cutting blade is formed on one end thereof, and the other end thereof is mounted on one side of the lower surface of the front end extension reinforcement plate. The excavation bit (500) and the screw wing rotate to drill the ground, and then the front end extension reinforcement plate is seated on a bottom surface of a drilled hole and grouts the bottom surface to increase front end bearing power. |
