Hey guys, I have to install between 2 and 4 2" PVC schedule 40 pipes under my walkway in the backyard. Anyone have a good idea on how to accomplish this quickly and cheaply?

I already dug out on both sides. The walkway is about 36" wide. Cutting into the concrete is a no-go. I was going to try cutting a piece of 2" PVC on a angle, driving it in a ways, twisting it and pulling it out to cleanout the dirt/clay in the section of pipe and reinsert and repeat. If I had only one pipe to run, no biggie. The issue is I have at least 2 and possibly 4 of these bastards to run under the walkway.

As always, any and all suggestions are appreciated. I know they make some products that are long rods that go in a section of pipe and allow you to drive it through with a sledgehammer, but I don't think I would be able to rent one locally and I would really like to get this done tomorrow so I can fill it all back in before the rains on Friday.
