Change-Manhole cover

when the workers working under the sewer,there should be some roadblocks around the entrance of the sewer to prevent the people and cars to pass and avoid the dangerous things. C.manhole cover can divide manhole covers into halves just like two roadblocks.The workers would not worry about there being no roadblocks.The manhole cover is made up of kinds of meterials which are very high denstiy and strong that always are used to cost iron.This kind of manhole can avoid being blowed down by wind. covered by the manhole cover,the alert symbol on the manhole cover can remind pedestrians that there is a cellar well and please pay attention.
