If you are trying to put PVC pipe/conduit together dry it will be difficult
or impossible. Glue will soften the PVC and if you move quickly the pieces
should slide together. Look for a glue designed for this product, I do not
believe electricians use a primer.

I am trying to join sections of 2 inch (nominal) PVC conduit for burial in a
trench.
This is schedule 40 electrical conduit, not water or drain pipe.
I cannot get the sections to mate. The belled portion of the conduit
is too snug on the main body. Even with the proper primer and
cement, it is so snug that I cannot manhandle two pieces together,
much less dozens!
I found that the sweeps I bought would go on with some difficulty.
The short couplers, about 3 inches long will fit, but give very little
overlap, only about an inch if fully seated.
I notice that the electrical drops down the power poles around
here have the same PVC conduit, but instead of using the
built-in bell ends, the crews apparently just use the short couplers
on the straight end ( I guess they cut off the bells?).
I am worried that the short couplers may not provide adequate
strength when the conduit is stressed to drop in into the trench.
Any experience?
