Borrowed a friend's backhoe for a couple projects 2 weeks ago & dug a trench across the driveway just before it had to go home. Trench us to deep (kind of by design). I finally picked up the required 25' of culvert yesterday. 12" double wall corrugated outside smooth inside stuff.
How well do I have to worry about tamping under & around the culvert? It's going to be snowy & muddy for the next week or 2, so good tamping really won't be possible. And the trench is slowly starting to cave in, especially with the moisture. 3' trench, 1' of culvert & generally you need 1' over the culvert, so I need to backfill a foot or so.
Not to worried about settling causing a dip as I have a box blade & maintain the driveway regularly. Not to mention needing to dump more gravel on it this summer or fall.
I'm mostly worried about the culvert crushing before stuff settles or it getting really out of kilter.
Can I skimp on tamping because of the mud? Should I wait for it to dry out a bit in a few weeks & manually re-excivate the trench as needed & tamp by hand? We can drive around for now, but it's tearing up the grass a bit.
I do need to re-grade the exit side of the trench smoother & a bit deeper a but should be able to do that with the box blade after the culver is in & leveled just past plumb so water will flow.
