摘要

提出一种垃圾填埋场土工膜渗漏快速检测方法,包括测试小车上配套的测试探极、信号处理电路、数据采集系统、GPS定位装置、计算机数据分析与模型建立系统;测试探极通过导线和高压(1 000v)信号源正极,高压(1 000v)信号源的负极直接连接高压电极,在垃圾场内形成高压直流电场,采用电压场多维矢量分析.该方法无需对垃圾填埋场大规模翻土或大量铺设检测电极,且不同于平面电压场分析法,可对渗漏点快速定向定位搜索,从而提高检测效率、降低劳动强度.%A landfill geomembrane leakage rapid detection method is given,including the test probe test trolley supporting poles,signal processing circuit,data acquisition systems,GPS positioning device,computer data analysis and model systems; test probe through the wire andconnecting the high voltage electrode,the negative terminal of the source of high voltage (1 000 V) positive electrode,the high voltage(1 000 V) direct signal source to form a high-voltage DC electric field,using multi-dimensional vector analysis of the voltage field.The method does not require large-scale dig landfill,and does not require a large number of laying the detection electrode.Unlike the previous flat-voltage field analysis,is can rapidly get the direction and location of the leakage point,to improve the detection efficiency and reduce labor intensity.
