混凝土结构物渗漏检测技术

The Leakage Testing Technology of Concrete Structures

基于地质雷达技术和微波湿度方法建立了一种全新的混凝土结构物渗漏检测技术。该技术采用地质雷达对结构物进行整体扫描,判定渗漏部位;并以此为基础,利用微波湿度仪对渗漏程度和渗漏范围进行精确判定。两种技术手段结合可以避免各自局限性,提高测试精度。实验研究和工程应用结果表明:该技术体系具有快速、准确、全面、高效等优点,可以应用于混凝土结构渗漏的定位和评价。

A new technology for evaluating leakage of concrete structures was established based on ground penetrating radar and microwave moisture detection technique. The condition of the concrete structure was firstly evaluated with ground penetrating radar to find the location of leakage, and then the degree and range of leakage were diagnosed accurately with the microwave moisture detection technique. Combination of the two methods could minimize the limitation of the individual and improve the accuracy. The results of experimental research and engineering application demonstrated that the system had numerous merits in locating and evaluating the degree of leakage in concrete structure. It was accurate, efficient, and comprehensive, meeting the requirements of engineering purpose.
