Research on the Construction Application of Segmental Hoisting Technology of Super-Long Rebar Cage
Addressing issues like unstable center of gravity,construction environment limitations,and lifting equipment constraints that may arise during the hoisting of super-long rebar cages,this paper takes the hoisting project of the ground-connected wall rebar cages in the second bid section of the raw water pipeline(main section)bypassing Songmushan Lake Reservoir in Dongguan,Guangdong Province,as a case study.By analyzing the processes of rebar cage fabrication and reinforcement,lifting point selection,machinery choice,segmental hoisting construction,and hoisting verification,the study summarizes the challenges,solutions,and key control points encountered in the practical application of segmental hoisting technology.The results of this research can provide design experience and engineering case references for the hoisting construction of super-long rebar cages,aiming to enhance construction safety and efficiency.
