Can I set this pool in the ground?

I have one of these

Can I dig an appropriate size hole and put this in it? I was going to line the hole with polythene sheet then Celotex boards to insulate and protect.
I realise this isn't conventional but I don't have the budget for a 'proper' pool and can't see why it shouldn't work.
Was then going to deck around the top and construct an overflow for excess rainwater.

Thanks!
