A structure for installing a post in road facilities and a construction method thereof are provided to construct the post firmly by excavating around a boundary stone, mounting a trapezoid form, placing the post in the form and injecting concrete. A post(10) is installed in the center of a form(20), and the form is composed of a rear trapezoid plate(21) having a narrow upper part and a wide lower part and a side plate(22) protruded forward and extended at a side of the rear plate. The upper and lower parts of the form are opened to inject concrete easily, and the front of the form is opened and contacted to a boundary stone in injecting concrete. The post is installed firmly and stably with the rear trapezoid plate. Plural holes(211) are formed in the rear plate and the side plate of the form. Concrete flowing out through the holes is hardened so that the post is fixed firmly. |
