Despite it being somewhat substandard, that 90 degree long bend will probably be OK in reality as it's just for rainwater and a short length, provided you fit a roddable gully.

How to install a replacement drain gulley (Ed.)

Thanks everyone, I've a little thinking to do. Do I need a new chamber probably not,i can connect to the old one but as I've dug up all the old patio and removed lots of soil, I thought maybe a good opportunity to do the drains and start fresh. But apart from looking a little rough the old chamber is OK. Maybe just repair it and tlc it and move on. Again thank you guys you've been great.
Ivory windybottom and noseall, can you see inside my head.....that is exactly what I was thinking of. You are a pair of stars. Ten thousand thanks, I will be doing the job in 2 weekends time and will let you know how I get on.
I still say it's a botch! But in reality it is very unlikely to ever be an issue.
Not ideal, but not a bodge.
You mitigate the risks, i.e. as long as you can rod from both ends. There is a screw-on cap, stub stack inside the building and an IC at the other end on the drive.
Honestly, I'd do exactly the same faced with the scenario shown in the photo. Who wants a hatch in their kitchen, vastly preferable to have a buried bend.
But under a path, I don't know. It's a few years since I read the building regs on drainage, but I think a change of direction should have a chamber. In reality I wouldn't bother (and haven't) for a 45 degree bend. A rod would get past one no problem and still be able to be spun to ensure the head doesn't fall off. But a 90 is a bit more severe.

Nonsense. Not on a slow radius bend. Do you think they make them for fun?
It would be absolutely fine for flow, OK for sewage and definitely not a problem for rainwater.
The issue is a rod. It needs to be constantly turned to keep the end on. It can go straight through a 45, not a 90 so it would be really stiff to turn as it would need to continually bend in different directions.

Hey chaps, I've almost done my replacement, I've had a few issues, like the whole ptrap drain was literally covered from top to bottom in concrete. Don't know if that's normal but a real pain in the backside. Anyway I have posted a picture of the job so far.
