摘要
本文通过对某新建油库大型储罐外底板外加电流阴极保护系统投运时出现输出电流异常原因的调查分析,发现采用混凝土钢筋桩基-承台基础的大型储罐基础内钢筋与周边防雷接地极存在搭接电导通问题,从而影响储罐外底板阴极保护系统的正常投运;本文针对该问题提出了解决措施及建议.
Abstract
Through cause investigation analysis of output anomaly of cathodic protection current,in large storage tank operation in a newly build oil depot,using impressed current cathodic protection,bad bond conductance between the steel bar in large storage tank foundation using reinforced concrete pile foundation-cap foundation,and the perimeter lightning protection grounding pole,thus affecting the normal operation of the edge plate cathodic protection system of large storage tank.This paper puts forward some measures and suggestions to solve this problem.
