If your rim tape is sound, the problem must lie elsewhere. 80 psi is way too squishy, but I reckon you're maybe leaving a bit of the tube poking out of the rim somewhere. That would explain the blow outs when you're not even riding.
Take your time when you put a new tube in, and be uber careful round about the valve. Make sure you've pulled the tube underneath it right into the rim.
I went through a week of misery during the summer when I lost my ability to fix punctures. For seven days, I had pinch flats and tubes exploding as I slept. The first one was probably changed in too much of a rush. As the situation spiralled out of control - a inner tube slaughterfest - I got panicky and didn't take my time installing the others either. Slow and steady is the way to go. I even had a couple explode while I was inflating them. The noise in a confined space isnae real. I still get a bit jittery when I'm using the track pump...
