Breeze block wall foundation

[walsh713]

Dear Colleagues,

I am thinking of building a breeze block wall (with gaps/space to be able to remove and put back the drain covers), on concrete, which has a drain tunnel running underneath it. Pictures below, and the breeze blocks will be on the red line.
Normally, when building a wall on mud earth, you dig some of it up and pour concrete for the foundation of the wall. But I can’t do this on the concrete path that has a drain tunnel running underneath it.
How do I do this properly so that the foundation for the wall is how a professional would do it, so that the foundation is solid and the wall doesn’t move?.
Thanks.

How deep is pipework? Should be able to dig both sides up deep enough for foundation . Span over access with a concrete lintel .

As above really. One would use a pile and beam method, but it's expensive and time consuming.

Dear foxhole, the breeze blocks will be single layer - the red line in the picture is the approximate boundary.
The drain underneath is about a foot underneath. I don’t want to risk the drain cracking or collapsing by digging a foundation.

Is there a link to the pile and beam method?.

On a garden wall?

I'd be inclined to design in panels (no, not necessarily timber), probably contrasting, one of which would be removable where that cover is.

If you lintel over the cover, in addition to it looking stupid and horrible, access is still severely restricted.

That's the point I was making....

However, the OP did ask how a pro' would bridge a pipe in a professional capacity.
