Based on the layout characteristics of the first-stage and second-stage metal structure embedded parts, and combined with the site construction environment, this article analyzes the high precision installation method in detail. At the same time, various construction plans which are suitable for Three Gorges Project ship lift are put forward. These construction plans which have been successfully used in Three Gorges Project have solved many technological problems, such as the deformation control of the embedded parts, fast and accurate positioning, high precision measurement and so on. Meanwhile, these technologies provide a reference for the constructions of similiar projects.
