A drainage structure mounted with a sliding steel grating of a road is provided to improve the cleaning performance of the drainage by combining the two steel gratings and preclude the steel grating from being stolen by longitudinally inserting the steel gratings in the inner groove. A drainage structure mounted with a sliding steel grating of a road comprises a drainage(200) longitudinally extended at one side or both sides of the road; an L-shaped bar longitudinally mounted at the end protrusion of the upper end of the drainage; plural steel gratings(400,400',400'') mounted at the upper end of the bar; and a hinge(440) combined with the L-shaped bar at the steel grating and installed to hinge-fold the steel grating. The hinge is adhesively welded at a groove part(410). The bar is welded with a round bar to easily slide the steel grating at the upper part of the inner groove. |
