皮尔逊检测法在埋地燃气管道泄漏定位的应用

Application of Pearson Detection Method to Buried Gas Pipeline Leakage Location

由于检测孔查漏法无法准确定位城市埋地钢质燃气管道的泄漏位置,提出基于检测孔查漏法确定的泄漏管段大致范围,采用皮尔逊检测法确定燃气管道防腐层的破损点,最终针对防腐层破损点采用开挖方式确定具体的泄漏位置。

Because the hole leakage detection method cannot accurately locate the leakage position of city buried gas steel pipeline, it is proposed that an approximate range of leakage section is determined based on the hole leakage detection method, and the damaged point of the anticorrosive layer of gas pipeline is determined by Pearson detection method, finally the concrete leakage location of damaged point of the anticorrosive layer is identified by excavation type.
