Manhole covers are used to cover defenses on roads or deep wells in homes. They are used to prevent people or objects from falling. They are generally divided into circular and square. Generally, a circular shape is used because the circular well cover is not easy to skew, which can better protect the safety of pedestrians and vehicles.
It is mainly considered that the length of each diameter of the circular manhole cover through its center is the same, so if the manhole cover is rolled up by the passing vehicle, because the diameter will be slightly wider than the wellhead below, Will fall into the wellhead.
