PURPOSE: A resinous material side ditch water pipe and construction method thereof are provided to regularly maintain a gradient in a certain space by preventing left and right width deformation regardless of outside condition in order to ease a flow of water and to strengthen hanging condition of a drain grating. CONSTITUTION: A resinous material side ditch water pipe and construction method thereof comprises a U-shaped side ditch water pipe, a latching flange(11), a side insertion hole(12), a grating holding frame(20), and a balancing bar. The U-shaped side ditch water pipe is installed at the lower part and outside of a median strip or at space between an edge of road and a sidewalk. The latching flange is generated in the edge in the upper part of opening unit of the side ditch water pipe and includes a latching projection(11a). The side insertion hole is generated by being faced with the outside of the side ditch water pipe. The grating holding frame is connected to the latching flange by a fastening member(200) and hangs the edge of the drain grating. The balancing bar is connected to the side insertion hole in order to prevent rotation and prevents gradient deformation of the side ditch water pipe. |
