水利工程围堰施工技术研究

Research on Construction Technology of Cofferdams in Hydraulic Engineering

摘要: 随着水利工程规模的不断扩大，围堰施工技术在水利项目中的重要性愈加突出。围堰技术通过构建临时性或永久性围护结构，有效地隔离水流，保证施工区域干燥与安全。本文研究了围堰技术的不同类型，包括土石围堰、钢板桩围堰、木板桩围堰等，并分析了它们在实际施工中的应用优势与不足。同时，探讨了围堰施工中面临的防渗、防冲刷、材料选择等关键问题，并提出了相应的优化措施。研究旨在为水利工程围堰施工提供理论依据和实践指导，推动施工技术的进步。

Abstract: With the continuous expansion of hydraulic engineering projects, the importance of cofferdam construction technology in hydraulic projects has become increasingly prominent. Cofferdam technology effectively isolates water flow by constructing temporary or permanent retaining structures, ensuring a dry and safe construction area. This paper examines different types of cofferdam technologies, including earth-rock cofferdams, steel sheet pile cofferdams, and wooden sheet pile cofferdams, and analyzes their advantages and limitations in practical construction. Additionally, it explores key challenges in cofferdam construction, such as seepage prevention, scour protection, and material selection, and proposes corresponding optimization measures. The study aims to provide theoretical foundations and practical guidance for cofferdam construction in hydraulic engineering, promoting advancements in construction technology.
