install sump between piers
install sump between piers
(OP)
We wanted to install sump with less than 4' clearance from the piers. Would it be ok to excavate with a trench box? The other option might be to fabricate precast sump (with no integral bottom) lowered to design elevation by means of hydro/vacuum/fluid jet excavation. Sump bottom to be doweled-in cast in place with key way and/or approved water stop provisions.
Please advice which way to go.
