摘要
在需要探测的金属管道附近打勘探孔,将管道探测仪器的探头放入勘探孔内,利用电磁原理探测超常埋深地下金属管道位置。论述了探测方法与原理、探测数据的分析方法,给出了应用实例。实际探测结果准确可靠,燃气管道深度探测误差不大于1.5m,水平位置探测误差不大于1.0m。
Through drilling exploration holes near the metallic pipeline which needs to be detected and putting the detection probes into the exploration holes, the location of extraordinary buried depth underground pipeline is detected by electromagnetic principle. The detection method and principle and the analysis method of detected data are discussed, and the application case is given. The practical detection result is exact and reliable. The vertical detection error of gas pipeline is not more than 1.5 m, and the horizontal detection error is not more than 1 m.
