The manhole cover is used to cover the defense on the road or the deep well in the home to prevent people or objects from falling into the well.

The general manhole cover is divided into circular and square. In urban road management, circular is generally used, because the round manhole cover is not easy to tilt, which can better protect the safety of pedestrians and vehicles. The use of circular is mainly considered that the diameter of the circular manhole cover through the center of each circle is the same, so if the manhole cover is rolled up by the passing vehicle, because the diameter will be slightly larger than the wellhead below, It is wide, and the manhole cover will not fall into the wellhead, which has better protection.
