I believe that everyone should be familiar with the manhole cover, but now that the manhole cover has been developed for many years, it can be said that "there is no eye on the three days." It was not what we thought at the beginning.
There are many kinds of manhole covers. According to the material, it can be divided into cast iron manhole cover, cement manhole cover, BMC composite manhole cover, ductile iron composite material cover, SMC composite manhole cover and so on. The cas
Ductile iron is a kind of high-strength cast iron material. It is generally described as "iron-based steel". Its strength, toughness and wear resistance are higher than ordinary materials, so the application industry is wide-ranging.
The injury of the municipal road cover due to defects such as defects and theft has occurred. This article starts with the investigation of the current situation of the manhole cover, compares the advantages and disadvantages of several manhole cover
