地下管道探测技术及其发展趋势研究

Study of Underground Pipeline Detection Technology and Its Development Trends

国内地下管道存在资料缺失、管道状况不明的问题,给管理工作带来极大困难。文中综合研究了目前常用的地下管道探测方法,发现电磁感应法对地下管道探测效果显著。磁法具有探测能力强、分辨率高的特点,适用于金属管道探测。探地雷达法适用于非金属管道探测,但有效探测深度有限,可以采用惯性陀螺仪定位法和声学定位法进行补充。近年来,基于多学科技术交叉融合的综合探测方法成为地下管道探测技术发展的新趋势。

The problem of incomplete information and unknown conditions of underground pipelines in China bring great difficulties to management.This article provided a comprehensive study of the commonly used underground pipeline detection methods and it was found that electromagnetic induction method was effective for underground pipeline detection.The magnetic method had the characteristics of strong detection ability and high resolution,which was suitable for metal pipe detection.Groundpenetrating radar method was widely used for non-metal pipeline detection,but its effective detection depth was limited.The inertial gyroscope positioning method and acoustic positioning method can be used to complement the limitations of ground-penetrating radar.In recent years,an integrated approach that combines multiple disciplines has become a new trend for the development of underground pipeline detection.
