Abstract
According to technology requirements of installation precision and characteristics of rack, nut column of Three Gorges Project ship lift, and combined with the integrated environment the installation method and installation accuracy control elements have been in detailed analysis, put forward the suitable rack, nut column installation construction process and control measures for Three Gorges Project ship lift. In engineering practice, use the test of datum point to control installation precision of the rack and nut column, put forward the method that screw of finish machining technology to cooperate with jack to readjust as reinforcement measures of installation of the rack, nut column. Thus various high precision standard technical difficulties of installation of the rack, nut column, have been solved, provides the beneficial reference for the similar engineering construction.
