Differential Settlement Connections
Differential Settlement Connections
(OP)
Got a problem here in that I have a large concrete detention vault on piling to design on a site that could see 18 to 24" of long term settlement.
Does anyone have any flexible connection details for stormwater pipe into and out of the vault, plus water and sewer for the same situation, that they could share?
Any input would be appreciated. Thanks all.

This is a site with a five story wood frame condo on a PT podium slab with parking under, all resting on a pile foundation, piles extending up to 75 feet into an old flood plain outwash area. Bottom line is real lousy material leading to large differential settlements. These settlements are trying to be mitigaged with preloading the site, but the geothech has to finalize the figures yet. This is the worst case scenario and I want to pin down my options here.
I don't think drainage out of the detention tanks will be a problem, but going in, that's another matter to consider. My buddy's doing the Civil site drainage, but I'm doing the tank. As you said, it's going to be interesting to say the least. The water table elevation will be an interesting issue too.
