I recently did exactly the same job, and laid the line inside 2 Inch
plastic duct.The depth was about 8" and i packed rough sand around the
pipe.It goes across my drive as well and i've had traffic on it, so far
so good.The only thing i was told was not to put it inside water pipe
because if you have workmen in in your later years and they start doing
any digging they might cut through it."I think it's against the rules
anyway.

I am running oil pipes under a gravel drive where people walk and cars
drive. I was going to put the copper pipe inside some spare MDPE mains
water pipe I've got so it should be well protected.

How shallow a trench could I get away with?

It's not (just) that I'm lazy, I'm also trying to avoid damaging some
propane lines which also run through the same ground. I will have to
cross them at some point. Hopefully they will be buried quite deep.

Cheers

Nick.
