围井法在高喷墙防渗性能检测中的应用

Application of Surrounding Well Method in Seepage Prevention Performance Detection of High Pressure Spray Wall

为探索围井法在水利工程高压摆喷防渗墙性能检测方面应用的具体流程及效果,在分析围井法检测原理及技术应用要点的基础上,以位于永修县梅棠镇大塘村的枹桐水库为例,对水库大坝除险加固所采用的三管法高压摆喷灌浆工艺进行概述,并对围井法检测过程及结果进行了分析探讨。分析结果为水利工程大坝除险加固中应用围井法检测高压摆喷灌浆防渗施工质量提供了可靠依据。

The purpose of this paper is to explore the specific process and effectiveness of the application of the surrounding well method in the performance detection of the high-pressure swing spray grouting anti-seepage walls in water conservancy projects.Based on the analysis of the detection principle and technical application points of the surrounding well method,taking the Futong Reservoir located in Datang Village,Meitang Town,Yongxiu County as an example,the three pipe high-pressure swing grouting process technology used to strengthen the reservoir dams is summarized.The detection process and results of the the surrounding well method are analyzed and discussed.The analysis results provide a reliable basis for the application of the surrounding well method to detect the quality of high-pressure swing grouting anti-seepage construction in the reinforcement of water conservancy project dams.
