The present invention relates to a steel reinforcing material (10) embedded into a cast-in pile and a method for installing the cast-in-place pile using the same. The present invention enables spreadable rods (20) formed on the lower part of the steel reinforcing material (10) by installing multiple spreadable rods (20) of which one end is hinged to the lower part of the steel reinforcing material (10), coupling driving lines (40) connected to the ground, and inserting the spreadable rods (20) into an excavated hole inside the ground while the spreadable rods (20) are hinged to the steel reinforcing material (10), and thereafter operating the driving lines (40) on the ground. According to the present invention, the adhesion between concrete forming the cast-in pile and the steel reinforcing material (10) inserted into the concrete is remarkably improved. In addition, the strength of the pile is improved without the enlargement of a cross section by verifying the structure of the steel reinforcing material (10) formed on the front end of the pile. Accordingly, a bearing force of the pile is improved. |
