Patching clay pipe

[LazyDozer]

Hi There,
Was shaving off a concrete path with a manhole to recess it and unexpectedly hit a rain pipe diving near vertically along the outside of the chamber, elbow bend, straight bit, elbow and over the soil pipe encased in the path.
I have knocked a small hole in the elbow doing the vertical dive.
How best to patch this as patio goes on top. I was thinking fibreglass tape and epoxy putty. I have vacuumed out the debris.
Ideally I would change the elbow but it’s encased in hard concrete and tight against the chamber and fence.

Thanks for your help!

Glass fibre should wok as long as it keys well to the pipe, otherwise perhaps a piece of broken ceramic pot with the same curve and fixed in place with epoxy resin would do it.

Roughen up the glaze then use some overlapped scrim and mortar
