Today, let's talk about why the hole of the composite well cover is easy to break. The main reason is that too much quartz sand is added, the resin content is low, and the glass fiber can't flow inside. The surface layer of the well cover is thin. If there are small stones on it, the vehicle will crush the well cover, and the hole will appear over time (as shown in the figure below), which will affect our traffic Safety. As the manufacturer of manhole cover, it is not recommended to use the manhole cover with sand addition. There is no small matter in safety, and the responsibility is greater than days.
