Drain access repair/rebuild

[ellal]

I'm building a new front dividing wall, and on digging out the foundations the state of one side of our drain access has become apparent.

There is a gap between the brickwork and the cover (which needs reseating).
Ideally I'd like to take a further level of bricks out so that the foundations could be a bit more level, but am fearful of the whole thing collapsing.

So my questions are.

1. Could the bricks be left in-situ and form part of the foundation of the new wall?
2. If so how best could the cover be reseated given the gap?
3. If best to remove the bricks, how to rebuild that side - with shuttering to contain the foundations, or some sort of lintel?

The wall itself will be stepped as there is a fall of 40cm down the drive. Plan is for a double width wall with max height of 1m at highest end.

Cheers

I would leave the bricks in situ and just build around it, place concrete either side to stabilise it then cut back any brick work if needed

Thanks for the reply.

The bit I am most concerned about is the side of the drain cover next to the existing bricks. Due to the gap, in effect the existing cover is only seated on 3 sides and ideally I'd like it to be on all 4 when replacing but not sure how best to go about it.

Remove the first course of bricks on the manhole - then as the wall comes up have a row of bricks @ 90 degrees sticking out halfway of the 9inch wall to support the iron rim Iike this I-

Would that be stronger than say running a concrete lintel parallel to the new wall?
