摘要

Performing post-grouting of a drilled shaft includes forming the drilled shaftusing aplurality of hollow rebar tubes, where each of at least one pair of hollowrebar tubes has acentral longitudinal opening, coupling the at least one pair of hollow rebartubes to a groutdelivery mechanism disposed below the shaft, and providing grout to the groutdeliverysystem through the at least one pair of hollow rebar tubes. Each of the atleast one pair ofhollow rebar tubes may include threads or ridges that eliminate debonding ofthe hollowrebar tubes from concrete of the drilled shaft. The hollow rebar tubes may beTITAN 52/26,TITAN 73/53 and/or TITAN 73/56 hollow threaded rebar. Each of the at least onepair ofhollow rebar tubes may further provide structural reinforcement of the drilledshaft. Thegrout delivery mechanism may include a perforated pipe.
