渠道防渗新技术已经在水利工程建设中得到了广泛的应用,渠道防渗是南水北调中线工程建设过程中的重点和难点,是工程建设质量控制的关键点。文章结合南水北调工程建设的实践,通过对南水北调中线干线工程土工膜工程的质量控制与改进、渠道倒虹吸与渠道连接处防渗的质量控制、钢筋混凝土衬砌板之间防渗的质量控制等经验进行提炼,对南水北调中线工程渠道防渗工程的质量控制与改进经验进行了总结,以期对类似的引调水工程渠道防渗工作提供借鉴。
New technologies for seepage prevention of channels have been widely used in water conservancy projects. Anti-seepage of water channels is the key and difficult point in the construction of the midline of the South-to-North Water Diversion Project, and is the key point for the quality control of the project construction. Based on the practice of the South-to-North Water Diversion Project construction, this paper analyzes the quality control and improvement of geomembrane project of South-to-North Water Diversion Middle Route Project, the quality control of seepage control of channel inverted siphon and channel connection and the quality control of impermeable between reinforced concrete lining And summarizes the quality control and improvement experience of canal seepage control project in the midline of South-to-North Water Diversion Project so as to provide reference for similar channel seepage control of diversion water project.
