Gluing 4" underground clay pipe

[Alex]

If I was going to do it ,I would use a silicone adhesive then bind the joint with plaster type bandage.and then set the joint in a mortar bed with a water proof mix.

I need to make a new connection into a 4" clay pipe... unfortunately the socket has broken with about 2" of the rim missing.

So, I was thinking of gluing the fractured piece (which is to hand) back in and dropping in a short section of 4" pipe, also 'gluing' that in somehow to make a watertight seal. Thereafter fitting a connecter for110 mm pipe. There is an alternative of cutting off the rim off altogether and fitting the connecter to the section 4" pipe left, but this is very much plan B as this remaining section is very short (

Just go back to the next pipe or build an inspection hatch (manhole) there. It doesn't even have to come to the surface does it? And anyway it wouldn't hurt if it did. Have you ever tried rodding around a bend?

It would save all that.
