In the manhole covers on the road, we often see cast iron manhole covers that are uneven to the road surface, which affects the travel of pedestrians and vehicles. Why does the nodular cast iron manhole cover sink?

     Investigating the root cause, the sinking of the manhole cover is mainly due to frequent heavy pressure, which may be due to overweight vehicles, or unreasonable installation, etc., which will cause great safety hazards.

     When the cast iron manhole cover manufacturer produces and designs the main body of the cast iron manhole cover and the design scale of the structure around the well, the backfill around the well and the structural layers of the road around the well also have special reinforcement designs.

     Urban traffic has a large number of heavy vehicles, and damage can form in and around the well. Secondly, it may also be due to the unreasonable planning of the pipeline layout through the driving range of the car. The structure of the well is fixed by its own weight and vehicle load.

     Choosing our ductile iron well can greatly ensure the safety of pedestrians, prolong the life of the manhole cover and increase the bearing capacity. Better adapt to various environments.
