帷幕灌浆施工是水库除险加固工程的技术关键,不但提高了坝基的防渗效果系数,也实现了工程低成本造价目标,是目前小型水库大坝渗漏处理的最优选方案。文章以辽河流域最重要的水利枢纽工程之一清河水库为背景,探讨了大坝除险加固工程中帷幕灌浆的设计、试验及施工过程,证明帷幕灌浆施工技术在大坝除险加固工程中的特殊价值。
The curtain grouting construction is the key technology of the reservoir reinforcement project, which not only improves the seepage prevention effect coefficient of the dam foundation, but also realizes the low-cost cost objective of the project, which is the most preferable solution for the dam leakage treatment in small reservoirs at present. In this paper, the Qinghe reservoir, one of the most important water control projects in the Liaohe River Basin, is taken as the background. The design, test and construction of curtain grouting in the dam reinforcement project are discussed. It is proved that the curtain grouting technology in the project of dam reinforcement and reinforcement Special value
