<p>The present invention relates to an underground buried pile and, more particularly, to an underground buried pile comprising: a body portion; a skirt portion arranged on the outer peripheral surface of the body portion; and an inner portion having a coupler, which is open from the skirt portion such that a striking rod can be inserted. The present invention provides a skirt portion which is unfolded to the outer peripheral surface of the pile and reinforces the drag, when the pile is struck and inserted into the ground, thereby securing firm fixing. In addition, a plurality of piles are connected by a string or a wire such that insertion of the piles and installation of a string for connection can proceed simultaneously, thereby improving operational efficiency. A dedicated striking rod has a toothed structure formed on a head portion thereof, the toothed structure being coupled to the inner portion of the pile, thereby enabling firm installation of the pile.</p> |
