Document Description
The purpose of the project is to repair scour areas on the toe of the Our House Diversion Dam spill apron. Repair work would take place in the following steps: 1) install water diversion; 2) pressure wash the scour area with water to clean the area and expose sound concrete; 3) drill dowels into the concrete; 4) epoxy dowels into the holes; 5) mobilize a concrete pump and hoses to a level area near the apron, all underlain with polyethylene plastic sheeting for ground protection; 6) apply bonding agent on the surface to receive shotcrete; 7) place shotcrete; 8) clean up shotcrete rebound and remove the plastic sheeting; 9) allow shotcrete to cure; and 10) remove water diversion (after completion of mechanical sediment removal work). Additionally, the anchorages of the access bridge of the dam will be repaired simultaneously.
