A steel grating with a drainage function is provided to obtain steel grating and draining functions, using two spaces divided by a main body, and to move the steel grating along the installation direction of the trench by installing buffer rollers and first rolling members. A steel grating with a drainage function comprises a main body(100), connecting parts, a cover body(200), buffer rollers(130), first rolling members(131), and a hinge part. The main body is fitted to a concrete trench(10), is formed with rolling holes(110), and has a partition plate for dividing upper and lower spaces(a,b). The connecting parts are placed at two sides of the main body. The cover body is hinged to one side of an upper end of the main body. The buffer roller is arranged to expose one side of the rolling hole. A part of the first rolling member is exposed to the first rolling hole. The partition plate is opened/closed and rotatative by the hinge part. Second rolling holes(151a) are formed at two sides of the main body. The second rolling holes are formed with second rolling members(151). |
