Tying a Concrete Facing to an Existing Bin Wall
Tying a Concrete Facing to an Existing Bin Wall
(OP)
Hi, we are working on putting together a bid for a Design/Build project where we are to rehabilitate an existing bin wall by "tying" new rebar to the existing wall and then placing a cast in place 8" wall facing on the front of it. The spill thru slopes in front of the pile supported abutments were pulled back to allow another lane of traffic to pass under the bridge 20 years or so after it was originally built. They used a light gage crib wall to support the embankment. By light gage I mean the stringer gages are 12 at the bottom and 16 at the top. The wall is about 18.67' tall. As in most design/build scopes, it is mainly left up to the contractor to come up with a solution. The only guidance like I mentioned above. Face the existing wall with 4000 psi concrete. Provide reinforcing steel and tie the steel to the face of the existing bin wall. Minimum wall thickness of 8".
Anyone have any good ideas on how to tie rebar to the existing light gage bin stringers?
Thanks,
Greg

How thick are the vertical connectors in a bin wall? I assume these are more of a bent plate element as opposed to a rolled light gage product? Could a nut be welded onto the vertical connector? Or could you even weld a headed stud onto the vertical elements?
