城市复杂埋设条件下的非金属燃气管线探测

Detection of Non-Metallic Gas Pipeline Under Complex Urban Burial Conditions

非金属燃气管线探测是管线探测行业的难点。本文在分析非金属燃气管线探测难点的基础上,介绍如何利用管线埋设的现场情况及已有资料情况实施初步定位,并提出了采用探地雷达验证的方法来提高定位准确度。最后针对探测定位过程中应注意的事项进行了说明。

The detection of non-metallic gas pipeline is a difficult point in the pipeline detection industry.On the basis of analyzing the difficulties in detecting non-metallic gas pipelines,this paper introduces how to carry out preliminary positioning by using the field situation of pipeline burial and the existing data,and puts forward the method of using ground penetrating radar to improve the positioning accuracy.Finally,the matters needing attention in the detection and positioning process ar e explained.
