地下管线材质结构对探测作业的干扰

Interference of Material Structure of Underground Pipeline to Detection Operation

本文讨论了不同类型地下管线材质结构对于探测作业的干扰。分析了电力、电信、热力、燃气、给水、排水等几类常见地下管线材质结构对于探测作业时作业员接收到的二次场信号强度和稳定性的分析,以及对于管线探测作业的干扰程度,提出了作业员可以放心使用的电磁法探测地下管线的工作方式和需要注意事项,实现了帮助作业员将地下管线依据类别和材质结构的不同建立起一体化的探测工艺流程。

This paper discusses the interference of different types of underground pipeline material structure to the detection operation.This paper analyzes the material structure of electric power,telecommunication,thermal power,gas,water supply,drainage and other common underground pipelines,analyzes the strength and stability of the secondary field signal received by the operators during the detection operation,as well as the interference degree of the pipeline detection operation,puts forward the working mode and matters needing attention that the operators can detect the underground pipelines with the electromagnetic method at ease,and realizes help operators to establish an integrated detection process flow for underground pipelines according to different types and material structures.
