A correlator trench and conveyor pit assembly features a six-inch concrete wall reinforced with number four bars at twenty-four inches on center with standard hooks. The wall ties into a concrete slab-on-grade reinforced with number four bars at eighteen inches on center each way, and sits on an eight-inch concrete footing reinforced with number four transverse bars and three continuous longitudinal number four bars with three inches of clear cover. A twelve-inch epoxy dowel with a four-inch epoxy embedment ties the wall to the slab. The trench opening is framed with L3x3x3/8 angles anchored by half-inch diameter expansion anchors at twelve inches on center with a four-inch minimum embedment to support manufacturer-specified grating.
