浅谈城市地下管线探测方法

Introduction to Urban Underground Pipeline Detection Method

本文根据南通市多期地下管线探测的实践,简要介绍了城市地下管线存在的问题、地下管线探测的内容和意义、地下管线基于物理性质的分类以及当前地下管线生产作业中主要采用的探测方法,并结合当地地下管线的敷设特点和作业手段,对主要专业管线的探测方法进行了详细描述,讨论了一些作业方法和特殊地下管线的探测过程,并提出了优先确定地下管线的探测顺序及其判断原则、重视明显管线点查找和地下管线施工信息的收集、增强目标管线的磁场信号、灵活运用各种探测方法等建议。

In this paper, according to the Nantong city stage of underground pipeline detection practice, it briefly introduces the existing problems of city underground pipelines, the content and significance of the underground pipeline detection, the classification based on the physical properties of the underground pipeline, and the detecting method which used in current underground pipeline operation. Combined with the local underground pipeline laying characteristic and operation method, the main professional pipeline detecting method is described in detail. It discusses some operation methods and special underground pipeline detection process, and proposed the priority determining underground pipeline detection sequence and the judgment principle, the attention to significant pipeline point search and construction of underground pipeline information collection. It enhance the target pipelines magnetic signal, and the flexible use of various detection methods and suggestions.
