Application of GPR method in special oily sewage pipeline leakage detection
The exploration and determination of leakage of underground pipes is always a difficult problem,especially for some special underground pressureless metallic pipes,which were used to transport the high temperature sewage.In this paper,the ground penetrating radar (GPR) method was applied to detect the special oily sewage pipes leakage problems.The analysis result showed that the veracity of the exploration was controlled by the diffused form of the contamination and the general conductivity and permittivity of the contamination and the water of pores,while these factors is influenced by the porosity and the saturation of the soil,and the reciprocity between the contamination and the water of pores.These brought the variation of physical and chemic properties of the contaminated zone.Finally,we divided three types of the GPR profiles according to the anomaly characteristics,and got the possible leakage position.The results showed the feasibility of using GPR method to detect the special oily sewage pipes problems.
