Well covers are not unfamiliar to everyone. Nowadays, we usually see nodular cast iron well covers as the most, which are basically round. So the question arises. Why are the covers round in shape? Can't other shapes work? This problem will be introduced in detail by our Shandong Ductile Iron Well Cover technicians.
Usually in the environment, the most common type we see on the road is the round one. This is because the circular well cover is more stable than the square one, and it is not easy to appear the sign of unstable inclination, so it can better protect the tranquility of pedestrians and vehicles.
In fact, the shape of nodular cast iron covers is almost certainly related to the utilization of material. Since the utilization of the covers depends on the size of the wellhead, if a square covers with an area far above the wellhead are to be installed, the utilization of material and the practical cost obviously do not coincide with the direct use of the circular nodular cast iron covers.
Since square ductile iron well covers are planned, it is stated that they also have specific application areas, that is, the use of tunnels and cable wells。 The square ductile iron well covers can probably be better prepared for the entry of liquid such as rainwater, in order to prevent the cable from being immersed in water。
