| titleOfInvention | No-leakage manhole cover |
| abstract | The utility model relates to a manhole cover, and aims at providing a no-leakage manhole cover. The no-leakage manhole cover comprises a manhole cover and a manhole cover base, wherein the manhole cover is hinged with the manhole cover base. The no-leakage manhole cover is characterized in that a protrusion facing to the manhole cover base is arranged on the edge of the manhole cover, a groove is formed in the edge of the manhole cover base, the bottom surface of the groove is matched with the protrusion, and a drain hole is formed in one side, close to the outer edge of the manhole cover base, of the groove. The no-leakage manhole cover can prevent rainwater or other sundries from entering a manhole and prevents pipelines and lines in the manhole from being stained. Meanwhile, the manhole cover is hinged with the manhole cover base, and the manhole cover base is fixed at a well mouth, so that the manhole cover can also be prevented from being stolen. With the special groove structure, the no-leakage manhole cover is crushing-resistant and safe. |
