How to raise a gully by 15cm using an adapter or something

[mrfixit1]

What do you experts say? Grey water and rainwater drain into a gully that needs to come up by 15cm, it used to be underneath a concrete path that was used as a hopper, now I'm going to use gravel. Is there something I can buy off the shelf? I have an idea to use a 110 plastic hopper with a concrete adapter. The cracks in the gully are only around the top where the path was chipped out, otherwise it works fine and doesn't leak.

A tall plastic hopper and an AC4000

Or even better, a 4D900 with a bit of 6” pipe to raise the lid.

Bizarrely, a thing called a gully hopper extension!

Polythene bag around the gaps before concreting around it

Great thanks you guys! I was just thinking about this and drew a plan.

gully hopper extension

How would I stop gravel coming in through the grate? Concrete into the holes?

Put some concrete kerbs around it above the level of the gravel and grate.

Why a large hopper would one of these do the job?

Maybe its useful for emptying buckets and the like.
