PURPOSE: A prefabricated waterway duct for a slope is provided to accomplish a slope construction and a waterway duct construction efficiently by preventing the waterway duct collapse and the slope sink. CONSTITUTION: A prefabricated waterway duct for a slope(10) is formed in a C shape with open top by integrating a bottom(12), a left incline(13), and a right incline(14). A space(16) formed like a half-cylinder is formed on the rear surface of the bottom. A fastener(17) of a bar shape with a screw thread is installed in the space. One end of the fastener is fixed by being connected with a reinforcement rod inserted in the bottom. The other end of the fastener is coupled by nuts(21,22) with a grid(20) of a long plate form, in which a fastening hole(19) is formed. |
