向家坝水电站冲沙孔复合钢衬施工技术

The Construction Technique for Sand Excluding Hole Composite Steel Lining at Xiangjiaba Hydropower Station

为了提高安装质量,加快施工进度,向家坝水电站冲沙孔复合钢衬在安装过程中采取了摞节凑合节制安施工技术,成功实现了摞节凑合节整体安装就位。该项技术通过对钢衬制造及安装全过程精细控制和管理,保证了工程质量,减少了现场安装工作量,经济效益显著。

In order to improve the quality of the installation and speed up the construction schedule,we installed whole embedded expansion joint during the installation process,successfully finished the installation of a expansion joint.As a result of the accurate control and management in the whole process of manufacture and installation,both the quality of the project is ensured and a lot of installation work is reduced,which gave significant economic benefits.
