How to solve the collapse of ductile iron well cover? [method]
In case of collapse of nodular cast iron well cover, it is either due to long-term use, or due to its own quality and improper use, which will lead to collapse beyond its load capacity. At this time, we need to re construct. The methods are as follows:
Ductile iron manhole cover
1. Clean up the collapsed earthwork and take out the ductile iron well cover. If the product is damaged, it needs to be replaced.
2. First, maintain the surrounding of the sinking road surface of the ductile iron well cover to prevent the passing vehicles from sinking in, causing unnecessary losses.
3. When replacing the ductile iron well cover, the lime soil shall be compacted strictly, and the manual compaction and layered compaction shall be adopted.
4. Check if the brick wall supporting the ductile iron manhole cover collapses. If so, re build the brick wall and plaster it.
5。 First, the cracked part of the road shall be chiseled, and the concrete slag shall be stacked aside, and then it shall be cleaned and transported out once the construction is completed。
In case of collapse of nodular cast iron well cover, it is necessary to replace and repair it in time to avoid potential safety hazard。
