Raceways in concrete for bridge

[Gategator37]

I will be working on a bridge in the upcoming months. I am researching some information on how to drain the PVC so water doesn't build up and leak at the couplings. I can see this causing spalding on the conrete. Does anyone have a picture of a connector or coupling that has a drain. I am new at bridges, so any information would be much appreciated.

Thanks in advance.

I would think this would all be engineered. No?
