Application analysis of fine detection technology of urban underground pipeline
Fine detection of underground pipelines means that on the basis of conventional underground pipeline detection,special exploration is carried out for key pipelines or pipelines difficult to detect in engineering construction,and special instruments and methods are used to provide more accurate and detailed results of the status of underground pipelines for urban planning,design and construction through high-quality,high-density or high-precision detection. Non-metal gas pipelines,large buried pipelines and trenchless buried power lines are often difficult to detect in actual geophysical exploration work. Taking the survey project of urban underground municipal infrastructure in Yuhang district of Hangzhou as an example,this paper fully analyzes the application effect of fine exploration method in the detection of the above three difficult pipelines and finally draws some useful conclusions.
