A tension reinforcing construction structure of a head extended pile and a construction method thereof are provided to effectively support the upper structure in an area where earthquake and transverse load is worried by suppressing the positive pressure of the pile upper structure with the foundation settlement of a tension member. A tension reinforcing construction structure of a head extended pile is composed of a head extended pile(10) which is manufactured to have an extended part(12) as a tube type hollow pile having a hollow(11) and installed in the perforated ground, tension members(20,30) which is installed in the hollow of the head extended pile so that the rear end protrude the rear end of the head extended pile and is formed to be longer than the head extended pile, a first filler(40) which is filled between the head extended pile and the perforated ground to fix the head extended pile, a second filler(50) which is filled in the hollow of the head extended pile to fix the tension member to the hollow of the head extended pile, and a foundation(60) which is constructed on the head extended pile. |
