The common structure of the sewer inlet cover plate is a grille cover plate structure. Since there are many weeds and branches and leaves in the green belt, the common grille cover plate structure is easily blocked, thus causing the sewer to be unable to drain normally. Especially in summer when there is more rain, after the sewer inlet cover plate is blocked, the drainage function of the drainage well will fail, thus causing waterlogging. Therefore, it is necessary to improve the structure of the sewer inlet cover plate to improve its performance of preventing blockage by sundries. Content of the Utility Model
