High precision installation technology of metal structure embedded parts of Three Gorges Project ship lift

针对三峡升船机工程金属结构一期及二期埋件的布置特点,并结合现场施工环境,对高精度安装作业进行了详细分析,提出了适宜三峡工程金属结构埋件安装的多种施工方案,并在三峡工程中得到广泛成功应用,解决了施工中埋件变形控制、快速高精度调整定位和高精度测量保障等技术难题,为同类工程的施工提供了借鉴。

Based on the layout characteristics of the first-stage and second-stage metal structure embed-ded parts, and combined with the site construction environment, this article analyzes the high precision installa-tion 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 accu- rate positioning, high precision measurement and so on. Meanwhile, these technologies provide a reference for the constructions of similiar projects.
