PURPOSE: A construction method of a soundproof wall foundation structure using a precast concrete segment is provided to easily construct and maintain a structure and to improve a soundproofing performance. CONSTITUTION: A construction method of a soundproof wall foundation structure using a precast concrete segment comprises a step of leveling a road or a surface of a foundation structure(ST) installed on the road; a step of punching a hole on the surface of a leveled foundation structure and inserting a pile into the punched hole; a step of closely adhering a supporter vertically penetrating the pile to the leveled surface and of vertically positioning the pile in the hole; a step of vertically fixing the pile into the hole in the hardening with a chemical grouting to be stabilized by injecting the chemical grouting into the hole through a pile guide hole of the supporter; a step of disassembling the supporter after hardening the chemical grouting inside the hole and of installing a bracket at same height with the pile; a step of inserting the upper part of the pile into the pile guide hole by pulling up a segment(81) including the pile guide hole and of putting up the segment in order to be hung at the bracket; a step of connecting the segment to the pile and the bracket by injecting the chemical grouting into the pile guide hole; a step of connecting the segment to the other segment through a joint plate on the end of the segment; and a step of filling a space in between the leveled surface of the foundation structure and the segment with a filler(84). |
