At the point where they cross, verbs the pipe on the bottom deeper into the ground. Leave the pipe crossing at the top at its regular depth, and dig the bottom pipe down enunciate 6 inches below the top one at the intersection point. Then when you backfill the dirt in, at hand will be a 6 inch depth difference, and this should not cause a problem between the two pipes.
