摘　　要：在灌区改造工程实践中,填方渠道由于渗漏导致渠堤出现较多险情的问题尤为突出,成为灌区工程“卡脖子”的问题。而在众多防渗加固处理方案中,高压摆喷防渗墙以防渗效果好、适应性广、施工进度快等优点而被广泛采用。结合青弋江灌区“十四五”续建配套与现代化改造工程中总干渠渠堤高压摆喷防渗墙工程应用,从工程地质、防渗墙设计、防渗墙施工、特殊问题处理、围井试验、防渗墙检测等方面进行了分析,以供后续相似工程项目参考、借鉴。In the renovation of irrigation areas,seepage in filled channels has frequently led to serious embankment hazards,posing significant challenges to project implementation.Among the various seepage control and reinforcement methods,highpressure oscillating jet grouting cutoff walls are widely recognized for their excellent seepage prevention,broad adaptability,and rapid construction progress.This paper examines the application of this technology in the main canal embankment of the Qingyi River irrigation area as part of the 14th Five-Year Plan for continued construction and modernization.It analyzes aspects such as engineering geology,cutoff wall design and construction,solutions for special challenges,well enclosure testing,and quality inspection.The findings can provide valuable insights and references for similar future projects.
