Well covers are indispensable in urban roads. The well covers in Shandong are damaged, which not only affects the comfort of vehicles Adaptability, but also caused a large potential safety hazard. How to identify whether it is damaged has become a problem we have to face.

1. If it is found that the surrounding of the well cover is not very tight, there is a large gap, and there are traces of rust, there is a great danger.

2. Looking at the location of the sewer and the surrounding road conditions, if the manhole cover is only embedded in the cement floor (and is at the entrance and exit of the community), there is generally no major problem.

3. The manhole covers on the roadside green belt are generally not to be trampled, especially those with incomplete edges, which are very dangerous.

4. As for the sewer cover around the parking lot, when parking, pay attention not to park on the manhole cover.

5. Prepare for lighting when walking at night. For places where there is no street lamp or the street lamp is dim, you should bring your own flashlight for lighting.

6. The well covers in some green belts are protruding from the outside. At this time, children should be prevented from playing on them and the well covers should be prevented from falling into the inside.

7. Don’t cross the street. There are many manhole covers on the road, and you should walk on the sidewalk when crossing the road.

The quality of Shandong well cover is also closely related to whether the road surface is damaged. In order to use a well cover for a long time, in addition to ensuring the quality, it is also very important to improve the construction and do regular maintenance.
