非金属材质排水管线的综合探测方法研究

针对城市中最常见的非金属材质排水管线,结合徐州市城市排水系统研究——排水管网普查工作,总结出“直接、观察、辨音、询查、物探”的综合探测方法,简述各种方法的实用性及优缺点。基于探测“泰奎大沟”的实例,阐述了使用地质雷达(GPR)获得地下反射波剖面,并分析排水管线反射特征来确定平面位置及深度,得到了很好的效果。五种方法可以综合使用,以获得排水管线埋深、管径、流向、空间位置等属性数据,提高管线探测的准确率,为管线探测者提供宝贵的经验。

Research on Comprehensive Detection Method of Nonmetal Drainage Pipeline

This article in view of the city of the most common nonmetal pipeline-drains,Xuzhou urban drainage system research—a classic case of drainage pipe network census,summarizes the comprehensive detection methods of“direct measurement,observation,sound identification,inquiry and geophysical exploration”,and briefly describes the practicability,advantages and disadvantages of various methods.Based on the example of detecting“Tai Kui”big river,this paper uses ground penetrating radar to obtain the underground reflection wave profile,and analyzes the reflection characteristics of drainage pipelines to determine the plane position and depth,which has achieved good results.The five methods can be used comprehensively to obtain the attribute data of buried depth,pipe diameter,flow direction and spatial position of drainage pipeline,improves the accuracy of pipeline detection,and provides valuable experience for pipeline detector.
