The present invention relates to a pile among the foundations of a construction structure, and, specifically, is to improve an existing hybrid composite pile. According to the present invention, a vertical bearing capacity is secured by inserting a primary pile (such as a PHC pile) by an ordinary construction method, and then a cover-type pile (a secondary pile) is additionally inserted to cover the upper section of the first pile so that an insufficient horizontal bearing capacity can be supplemented. Therefore, a required horizontal bearing capacity can be acquired through the cover-type pile regardless of horizontal bearing capacity applied to the first pile. |
