摘要
闸坝水平铺盖的渗漏检测一直是水利水电渗漏检测工程领域的难题。采用新型水下声纳渗漏流速检测和水下摄像及喷墨示踪的综合检测技术,对四川某闸坝的混凝土铺盖展开检测,清晰给出了渗漏流速分布等值线图,成功检测出水平铺盖渗漏部位,为后续闸坝的渗漏处理提供了有力支撑。介绍了渗漏检测原理、工艺、方法和检测成果分析等内容,可供其它类似工程的渗漏检测借鉴。
The seepage detection of impervious blanket of sluices is a difficult problem in seepage detection of water conservancy field. A comprehensive inspection for the impervious blanket of a sluice dam in Sichuan was carried out by a newly developed underwater sonar- seepage system together with underwater video and inkjet tracer technology. By the sonar- seepage detection system,the contour map of seepage velocity is obtained and the seepage location was positioned accurately,providing solid foundation for next seepage treatment construction. The principle,technique,method and result analysis of sonar- seepage system are presented,which could be referred by similar projects.
