Research and Application Analysis of Magnetic Gradient Method in the Detection of Deep Buried Metal Pipelines
In the era of rapid urban construction,the underground space is becoming increasingly complex,and the risk of safety acci-dents in the underground pipeline construction process is becoming higher,resulting in a large number of demands for the refined de-tection of underground pipelines.This paper introduces the development status of deep buried pipeline detection,discusses the detec-tion principle of magnetic gradient technique in the well,studies the detailed process,data processing method,depth calculation method,and result curve analysis of metal pipeline detection with magnetic gradient technique,and finally expounds the practical ap-plication of magnetic gradient technique in three engineering scenarios of underwater pipelines,precast concrete pipelines,and small diameter pipelines.It meets the detection requirements of deep buried metal pipelines in actual engineering construction.
