We recently discussed this in the chat one night. While conduit under a slab need not be buried, when under open ground, SOME depth is necessary.
In this case, the weight of the slab pressing down, and the resistance provided by the sprinkler pipe, acted as a pair of shears- eventually leading to the break in the pipe, and the shorting of the wires within!

Interesting that the metal gave way to the plastic.

It's hard to tell, what with cement dust and age...but that conduit is grey PVC, not metal.

My bad. I took "pipe" to mean RMC.

The concrete is a pedestrian-only apron in front of a fast food place.

Lesson learnt - get in before the sprinkler guy.
