防渗技术在小浪底北岸灌区堤坝工程中的应用

Application of Seepage Prevention Technology for Dams in the Irrigation Area of Xiaolangdi North Bank Irrigation Area

堤坝是灌区工程的关键,只有做好堤坝的防渗施工才能够充分发挥堤坝的作用。但是,灌区工程堤坝在运行过程中很容易受到各种因素的影响,例如:材料缺陷、技术缺陷、自身形变等,在这些因素的影响下,灌区工程堤坝很容易出现渗漏的情况。为了提升堤坝的防渗性能,可以在堤坝中应用灌浆防渗技术、防渗墙技术以及复合土工膜技术等防渗技术,其中灌浆防渗技术包括劈裂式帷幕灌浆施工技术、高压填充式灌浆施工技术、灌浆加固技术以及低压速凝式灌浆技术等类型,施工单位需要根据堤坝的实际情况选择合适的防渗技术。在应用防渗技术的同时,施工单位也需要优化堤坝防渗体系、清除滑坡,为防渗技术的应用奠定基础,优化防渗技术的应用效果,提升堤坝的防渗性能。

The dam is the key to the irrigation area project.Only by doing a good job in the anti-seepage construction of the dam can the dam function fully.However,the dams in the irrigation area are easily affected by various factors during the operation,such as material defects,technical defects,self-deformation,etc.Under the influence of these factors,the dams in the irrigation area are prone to seepage.In order to improve the anti-seepage performance of dams,anti-seepage technologies such as grouting anti-seepage technology,anti-seepage wall technology and composite geomembrane technology can be applied in the dam.For types of construction technology,grouting reinforcement technology,and low-pressure quick-setting grouting technology,the construction unit needs to choose the appropriate anti-seepage technology according to the actual situation of the dam.While applying the anti-seepage technology,the construction unit also needs to optimize the dam anti-seepage system and clear the landslide,so as to lay a foundation for the application of the anti-seepage technology,optimize the application effect of the anti-seepage technology and improve the anti-seepage performance of the dam.
