Digging a trench for pipes - worm pit while I'm at it?

A hair-brained idea just came to mind that I wanted to bounce off the fine folks around here.  I will likely be digging a 1 foot trench to re-route old collapsed underground gutter downspout pipes.  This will be a significant undertaking, entailing about 130 feet total length.  While I'm at it, would it be crazy to toss some scraps below the pvc pipe before I refill the trench to create a long "Worm trough", in the spirit of the worm pit idea?  

Thanks in advance.  

I think it would be better to put those scraps on top of the pipe instead of under it.

If worms dig their tunnels under the pipe, you might be re-digging that pipe up to repair a collapse caused by worm undermining.
Worms create tunnels at that depth (only earth worms go that deep) and any weight over those tunnels could crush them, leaving an air gap between the pipe and soil.
If you have the scraps on top of the pipe, there is no possibility of harm to either the pipe or the worms, they will have a big party.

I hadn't considered collapsing pipes.  Now that you mention it, I have to make sure I backfill it right and compact the soil enough to prevent this.  

I'll definitely throw some scraps above the pipe, though.  Thanks for the tip!

The common redworm needs an ongoing supply of food in order to be happy. So, if you put food below the pipes, you are not likely to renew that food supply and once it is consumed, the worms will wander off looking for their next meal. So, if you are going to feed them, make it easy on yourself and top feed.
