This invention relates to the field of urban construction, and more particularly to a drainage well cover for flood control and drainage, comprising a base, an mounting cylinder, and a water guide plate; the mounting cylinder is installed on the base. When flooding occurs on the road surface, the floodwater flows into the storage cylinder.
