What's the difference between plastic manholes used in general building communities and municipal plastic manholes? Who can talk about it?
Generally speaking, there is no difference between plastic manholes and drainage manholes. Please note that this manhole cover is not made of plastic, but of composite material, which is far higher than the fatigue, destructiveness and strength of concrete, and there are steel bars in it. Usually, the main difference between the community and the municipal government is reflected in the manhole cover. Residential areas are generally not heavy, and the standard of manhole covers is relatively low. After all, the car weighs only 2 tons, and the municipal government may face a dozen tons or even dozens of tons of trucks in an instant.
