摘要
简要介绍地下管道可检测范围，防腐层漏点地表位置，在管体位置漏点大小，开挖验证，防腐层绝缘电阻，管体腐蚀程度，管体是否穿孔等判断技术。
A number of judgment technology of underground pipeline detection are described in brief such as scope of detection, aboveground positioning of underground pipeline coating holiday, holiday size on the pipeline, excavation verification, anti -corrosion coating insulation resistance, condition of pipeline and pitting or hole penetration on the pipeline.
