[0012] Furthermore, the cover plate is provided with a plurality of through holes.

[0013] The beneficial effects of the utility model are:

[0014] In the utility model, the manhole cover is placed on the manhole cover base and the base foundation, the wellbore is separated from the base foundation and the manhole cover base, and the base foundation is placed on the road surface foundation. When the manhole cover is subjected to external loads, the manhole cover base and the base foundation disperse the external loads to the road surface foundation, protect the periphery and the inner side of the manhole cover, and prevent the manhole cover from being subjected to direct pressure from the upper load on the wellbore itself.
