Firstly, the round composite manhole cover is very useful in the road sewer. The round composite manhole cover has a strong, stable and durable structure. It can play an important role in daily maintenance of roads, sewers and fiber optic communications. In addition, the cost of materials is low, and the market is widely used to meet market demand.
In fact, the reason for using the round composite manhole cover is that the round composite manhole cover is flexible and easy to be made into square and round shapes. Its material is also very light, which can save a lot of cost in transportation and installation.
The reason people like to use round composite manhole covers is that they are not easy to tilt, which can better protect the safety of pedestrians and vehicles. However, if a square is used, since the square diagonal is significantly longer than the length of each side of the well, when the manhole cover is rolled up, it is easy to fall into the well along the diagonal direction of the wellhead, posing a hidden safety hazard.
