摘　　要：围堰施工技术不仅是我国水利工程中的一个重点,更是一项复杂的、系统性的技术,水利工程的建设与成功离不开围堰施工技术的应用,因此,通过对围堰技术进行分析探索,对我国未来水利工程的发展有着不可忽视的意义。以陕西省榆林引水工程大禹沟一级泵站黄河取水口围堰为实例,简要介绍围堰填筑的施工工艺流程,确定围堰压实度参数,高压旋喷防渗墙的修建以及围堰填筑后基坑抽排水的施工,最终使围堰施工质量达到设计规范的要求,保障后续工程的安全进行。The construction technology of cofferdam is not only a key point in China's water conservancy projects,but also a complex and systematic technology.The construction and success of hydraulic engineering cannot be separated from the application of cofferdam construction technology.Therefore,analyzing and exploring cofferdam technology has significant implications for the future development of water conservancy projects in China.Taking the Yellow River intake cofferdam of the Dayugou primary pump station in Yulin Water Diversion Project in Shaanxi Province as an example,this paper briefly introduces the construction process of cofferdam filling.By determining the compaction parameters of the cofferdam,constructing the high-pressure rotary jet grouting anti-seepage wall,and constructing the foundation pit drainage after the cofferdam is filled,the quality of the cofferdam construction can ultimately meet the requirements of the design specifications,ensuring the safety of subsequent projects.
