The present invention relates to a ground reinforcing pile with an improved end bearing capacity. The purpose of the present invention is to maximize stability of the ground by being easily installed, preventing a rupture of a pile hole, and obtaining a large end bearing capacity. According to the present invention, the ground reinforcing pile with an improved end bearing capacity comprises: a pile body (10) composed of a concrete body and a steel reinforcement to be embedded inside the concrete body; and a front end mounting means formed on a front end of the pile body, securing an end bearing capacity by being inserted and mounted in the ground around the pile body while protruding towards a circumference of the pile body in case of an installation of the pile body. The front end mounting means is composed of upper and lower finishing plates (50, 40) joined to an upper and a lower end of the pile body respectively, having nuts; a lifting rod screw-coupled to the nuts of the upper and lower finishing plates, and lifted by rotation; and an expandable mounting unit (20) of which the circumference is not exposed to the outside of the pile body, and formed into a streamlined shape convex toward a bottom connected to the lower part of the lifting rod to rotate the lifting rod on the spot, and securing a front end bearing capacity by being inserted and mounted in the ground around the underground pile hole as the circumference is projected to the outside of the pile body when a central part moves upwards due to an upward movement of the lifting rod. |
