管线探测技术在城市道路改造中的应用
Application of Pipeline Detection Technology in the Reconstruction of the City Roads

城市地下管线探测中，常遇到的地下管线主要分为三种类型：一类为金属管线，主要为给水管道、部分燃气管道等；一类为各种光缆、电缆线，主要为通讯电缆和电力电缆等；一类为非金属管线，主要为排水管道、部分供水管道和部分燃气管道等。地下管线材质的不同，其地球物理特征也会有明显的差异。本文结合实例阐述了电磁感应法及地质雷达法在不同类型管线中的应用效果。通过电磁感应法和地质雷达法在城市管线探测中的应用研究，能有效的确定管线在地下的分布规律，对后期城市道路的钻探及开挖具有指导性的意义。
In the detection of urban underground pipelines, there are three types of underground pipelines: One is metal pipeline, mainly including water supply pipeline and partial gas pipeline; the other is various optical cables and cable cables, mainly including communication cables and power cables; the other is non-metal pipeline, mainly including drainage pipeline, partial water supply pipeline and partial gas pipeline. The geophysical field characteristics of underground pipelines with different materials are obviously different. This paper expounds the application effect of electromagnetic induction method and geological radar method in different types of pipelines. Through the application of electromagnetic induction method and geological radar method in the detection of urban pipelines, the distribution law of pipelines in the underground can be effectively determined, which is of guiding significance for the later drilling and excavation of urban roads.
