HOLLOW REBAR FOR POST-GROUTING THE BASE OF REINFORCED CONCRETE DRILLED SHAFTS
Performing post-grouting of a drilled shaft includes forming the drilled shaft using a plurality of hollow rebar tubes, where each of at least one pair of hollow rebar tubes has a central longitudinal opening, coupling the at least one pair of hollow rebar tubes to a grout delivery mechanism disposed below the shaft, and providing grout to the grout delivery system through the at least one pair of hollow rebar tubes. Each of the at least one pair of hollow rebar tubes may include threads or ridges that eliminate debonding of the hollow rebar tubes from concrete of the drilled shaft. The hollow rebar tubes may be TITAN 52/26, TITAN 73/53 and/or TITAN 73/56 hollow threaded rebar. Each of the at least one pair of hollow rebar tubes may further provide structural reinforcement of the drilled shaft. The grout delivery mechanism may include a perforated pipe.
