Analysis of Technologies and Development Trends of Leakage Detection for Drainage Pipes
The leakage of drainage pipes will pollute the underground soil,and also cause more serious accidents such as cavities and collapses,which should be detected in time.The development trend of leakage detection tech-nology are surveyed through literature to analyze the characteristics,advantages,disadvantages,and current re-search hot-pots of mainstream or potential technologies such as CCTV,QV,soil sampling,ground penetrating radar,aerial thermal imaging,multi-electrode resistivity method,and shallow transient electromagnetic.Analysis shows that CCTV detection technology still needs further development in multiple technical directions in China;Any single detection technology cannot handle all types of detection tasks.In order to obtain accurate and complete status information of underground pipes,multiple technologies should be comprehensively applied;Shallow transient electromagnetic is a potential leakage detection technology.
