Just saw this, don't know if you've already proceeded. While the 80psi drip irrigation hose should work, I wouldn't bury it very deep at all. It compresses considerable easier than the 125psi hose. I recently picked up a 500' roll of the drip irrigation tubing for bucket habitats. I was suprised how easy it was smashed or kinked compared to the 125psi stuff.
Personally I would have hesitation using it in a below ground application after seeing it and having it in hand, especially in a 500' run.
Let us know how it works for you if you do decide to use it.
