How to repair the manhole cover

Manhole covers are very common facilities on urban roads, and their existence is directly related to the traffic and quality of life of citizens. However, due to the high utilization rate of roads, manhole covers have been subjected to wind, rain and sun friction for a long time, which is prone to various cracks and deformations, and even serious pavement damage. Let's take a look at the repair method of sewer manhole cover.

First, replace the manhole cover.

The manhole cover is seriously damaged beyond repair, and the whole manhole cover needs to be replaced. It is necessary to remove the old manhole cover with tools, clean up the damaged cement or asphalt materials at the roots, and then install a new manhole cover. The new manhole cover should also be inspected before installation to prevent a series of problems.

Second, fill the loopholes.

Small wear or holes appear on the surface of the manhole cover, so you can buy special manhole cover patches or self-made patches and stick them on the manhole cover to achieve the effect of repairing. Then coated with asphalt or cement materials, and the repaired manhole cover can be reinstalled and used.

Third, fill in the gaps.

There will be a gap between the surface of the manhole cover and the well edge, which is easy to accumulate debris and affect the normal drainage. This problem can be solved by embedding a mixture of lime and cement in the gap between the manhole cover and the edge. Slowly apply the mixture to each gap with a scraper to make it full and smooth.

Fourth, disassembly and maintenance.

If the manhole cover is tilted in a large area and cannot be used normally, it needs to be disassembled for maintenance. Relevant departments need to be informed in advance, and the surrounding environment and residents' travel cannot be affected during the demolition process. First remove the manhole cover, clean up the surrounding ditches, then repair the concrete and pipes at the bottom of the well, and finally reinstall the manhole cover.

When repairing the manhole cover, we should pay attention to ensuring high construction quality and avoid wasting maintenance funds and time again when problems arise. At the same time, attention should be paid to cleanliness in the process of repair and use to ensure road traffic safety and the quality of life of citizens.
