Inspection Chamber Question

[Ben SS]

Hello,

I'm laying down some tiles in my back garden. There are 2 inspection chambers that are close to each other and slightly angled compared to the house.

When i dug around it to see if i could turn it slightly i noticed it has a plate coming off it.

What could this be?

Ben SS, good evening.

An image would assist greatly??

Is it not just part of the base plate?

 

[Ben SS]

Haha sorry image helps

Nothing I’ve seen before near an inspection chamber. @HERTS P&D or @Hugh Jaleak might know.

You will need to dig around then and see what is underneath.

Isn't it a Recessed tray cover for manholes and inspection chambers:

This link shows the installation procedure, which might help you to move it:

Sorry, im talking about the panels to the side of it.

The final paragraph in the article, mentions lifting eyes will be required to lift the manhole cover out its frame, good possibility sand has wedged your 2 items tightly together. PS it will be very heavy.
The Finished Manhole Cover

The finished manhole cover is now placed in position, once its completed all you see in the 4 corners are the heavy gauge lifting eyes to accept standard profile lifting keys which are used to lift out the cover

Before you do much more, I'd lift the cover and see how big the chamber is underneath. Possible that might be part of a reducing slab, covering a bigger chamber underneath. Actually, are you on mains drainage?

 

[Ben SS]

Ive no idea. Its in my back garden and there is another thats 3 feet away.

If you can, post a photo of that one too. Also, perhaps the two together in the same shot?

 

[Ben SS]

Hopefully you can see both in the picture.

 

[Hugh Jaleak]

I've got half a suspicion you've a septic tank under there, given the positioning of the covers and the slab. Try and (carefully) clear the soil away between the 2 covers and see how far that slab extends. Although without lifting the covers and some pics of whats underneath, it's impossible to say for certain from behind a screen.

Ok....until 4 days ago, this area had been block paved over for many years. If I lay a new patio over it will this be a concern?
