As a key infrastructure ensuring urban operation

the safe and stable operation of urban underground pipelines is of vital importance.However

the positioning of deep-buried non-metallic pipelines[1](generally referring to those with a burial depth of more than 3 meters) has always been an industry challenge

posing significant safety risks to the construction of transmission and substation projects.Focuses on the detection technology for deep-buried non-metallic pipelines

elaborates on the principles of detection methods

operation processes

and application cases

and verifies and analyzes them through practical projects.The aim is to provide effective technical support and practical references for solving the detection problems of deep-buried non-metallic pipelines.
