Abstract
The overall construction program has been changed in the extension project of Three Gorges Project ship lift. Because of it, the tower column, rack, nut post, counterweight, and longitudinal guide rail should be constructed at the same time which forms the grade separation operation. In this case, conventional shelving scheme can not meet the requirement of construction. So the aerial comprehensive lifting platform is adopted which can quickly change the vertical construction site and meet the requirements of different parts and working procedures. This platform contains hoist lifting platform, gear-rack lifting platform, and hanging lifting platform. Comprehensive lifting platform can meet the requirements of the installation of metal structure, construction of second stage concrete, installation of mechanical and electrical equipment, concrete pouring of second stage concrete, and pagel grouting. It can relief the intense construction period. This technique after design can be popularized and applied in similar project.
