Manhole cover

A manhole cover is like a lid that goes over a hole in the ground. This hole is usually where there is something like pipes or cables underground that we need to reach sometimes.

The cover is usually round, and it's made of metal so that it's strong and won't break easily. It's also heavy so that it won't move around easily, especially when cars or trucks drive over it.

If we need to see what's inside the hole, we can take off the manhole cover by using a special tool. This tool is kind of like a big key that helps us unlock the cover so we can lift it up.

It's really important to have manhole covers because without them, it would be dangerous to have holes in the ground that people could fall into. Plus, we need to be able to access the things underground to fix them if something goes wrong. So the manhole cover keeps us safe and helps us do our jobs.
