I am seeking help for a recurring CATV manhole issue, just outside our property.
First of all here is a 4 second video tells what is happening at the moment.
The manhole cover is generating a metal clank noise every time a vehicle is driven on it.
Unfortunately this is only a few meters away from residential houses, and if a truck or a bus drives on it, the manhole will rock and causing some vibration of the building together with the noise.
The issue has been reported multiple times in the past, with the recent repair just happened this month. However after it was tightened, after 2-3 weeks it becomes loosen again and start to clank.
I don't understand:
- Why the manhole cover has to be a few inches below its surface? Why the lid/cover cannot be even on the road like most other manholes? (There are indeed quite a few down the same road but without the vertical gap.)
- Why this manhole has to be in the middle of the driveway, while the nearby pavement has enough space to hold it?
- Why the lid cannot be tightened up in a permanent way?
- Is there anyway to permanently fix the lid and stop it from clanking every 2 weeks?
