摘　　要：大型pccp管道空间弯头的安装既是管道安装的难点,也是安装的重点。文中通过对空间弯头吊装最佳吊点布设、起吊钢丝绳内力计算和吊装钢丝绳选择、钢桁架受力分析与制作安装等一系列的改进,由传统的分节安装改进为整体安装,达到了保证安装质量、提高工作效率、节省工程投资的目的。对类似工程管配件设计和安装施工都具有指导作用。The installation of the large space elbow of PCCP water conveyance pipeline is the difficulty of the pipeline installation, also is the focus of the installation. Through the series of optimization of the optimum lifting point layout in the hoisting of the space elbow, the internal force calculation of hoisting steel wire rope, the selection of hoisting steel wire rope, the force analysis of steel trusses and the fabrication and installation of the steel trusses,the traditional subsection installation is improved to the whole installation, which achieve the purpose of the en suring the installation quality, improving the work efficiency and saving the project investment, which has the guiding function for the accessories design and installation construction of the similar project pipeline.
