Ductile iron well cover is a comparative advantage in performance, but with the increase of usage rate, the problems will arise. One of the main problems is the phenomenon of well cover subsidence. What are the causes of its subsidence? In view of this problem, Shandong Ductile Iron Well Cover Manufacturer has also carried out a lot of research and analysis, the conclusions are as follows:
1. Ductile cast iron well cover and perimeter structure design scale is low. There is no special reinforcement design for perimeter backfilling and perimeter pavement structure layer.
2。 It is unreasonable to plan and lay pipelines in the scope of road for motor vehicles。
3. When installing nodular cast iron well covers, attention should be paid to a large number of heavy overloaded vehicles in urban traffic, and damage caused by inspecting wells and periwells.
4. Structural stiffness difference between inspection wells and peri-wells is large, and the settlement of inspection wells is different because of their own self-weight and vehicle load.
Ductile iron covers are constantly under heavy pressure, the covers with well rings are sinking as a whole. As a result of sinking, more problems appear in the chain, leading to the loss and damage of the covers, which has caused greater harm to the society. Therefore, we must take this into account when installing and transforming the products, and ensure the safety of production and manufacture. Guaranteed products.
