红外热像法在地下工程防水质量和渗漏检测中的应用

Application of Infrared Thermography in the Waterproof and Leakage Detection of Underground Buildings

利用红外热像法,对不同地下建筑工程防水层的施工质量与地下水渗漏点进行了检测试验,检测项目包括远/近距离对比试验、淋水前后对比试验、不同介质对比试验和修缮前后对比试验。结果表明,这项检测技术具有精度高、操作简便、对场地要求低的优点,是地下工程防水工程质量和渗漏检测的重要技术手段。

Waterproofing construction quality and groundwater leakage of different underground buildings are detected by infrared thermography, including distance contrast, before and post water pouring contrast, different materials contrast and before and after reparation contrast. The results show that infrared thermography has the advantages of high precision, easy operation and low requirements on site. Infrared thermography is an important technology for waterproofing construction quality and leakage detection of underground engineering.
