Ductile iron manhole covers have become mainstream

To cope with the risks of vehicle overload and pedestrian falling, ductile iron manhole covers (with twice the strength of ordinary cast iron) have become mainstream. Some products are embedded with "anti fall nets and anti displacement devices", and real-time monitoring of manhole cover status (such as tilting and opening alarms) is achieved through Internet of Things technology; In the renovation of old residential areas, intelligent manhole covers (integrated with sensors and communication modules) are being promoted synchronously to assist in the intelligent operation and maintenance of urban underground pipelines.
