reinforced concrete diaphram wall between concrete filled pipe piles

[foreng]

I want to install a 5m reinforced concrete diaphram wall between concrete filled pipe piles on a bridge pier. Looking for some reference material or has anyone complete a similar design. I've sized the reinforcement for moment and shear due to lateral loading on the bent. Trying to determine the best way to attach the wall to the pipe (i.e. run reinforcment through holes cut in piles, etc...)

If the pile sheath is steel maybe shear tabs and stirrups welded to them must work well. However it may be simpler and more ductile embed the stirrups in bored holes with epoxy; this may require some minimum size of the piles. It might be feasible then just make a central row of connectors, not one per side, for a more clean reinforcement scheme.
