Rubber mute inspection well cover
The invention discloses a rubber mute inspection well cover, which comprises a flat cast iron inspection well cover matrix; a plurality of elliptical drainage holes are formed in the cast iron inspection well cover matrix; the cast iron inspection well cover matrix is a round iron cake; the drainage holes are formed in the cast iron inspection well cover matrix in a ring array; a layer of rubber shock absorption shell wraps the cast iron inspection well cover matrix; the rubber shock absorption shell comprises rubber holes corresponding to the hole walls of the drainage holes. Through the mode of the rubber mute inspection well cover disclosed by the invention, the rubber shock absorption shell wraps the cast iron inspection well cover matrix, so that sewage cannot be directly contacted with the cast iron inspection well cover matrix, the rust problem is avoided, and the service life is longer; moreover, the rubber mute inspection well cover and the mouth of an inspection well are matched more tightly, so that the mute effect is good, and the comfort of vehicles running on the rubber mute inspection well cover is enhanced.
