- 摘要:
- 深井阳极床因具有占地面积小、保护电位均匀、接地电阻相对较小等特点,在许多复杂环境下的钢质管道阴极保护工程中得到应用。但深井阳极一次性投资高、施工复杂且要求一次成功,这就给施工提出更高的要求。文章从阳极井位的确定与打井方式的选择、阳极体下井、回填和接地电阻的测量等方面阐述了深井阳极施工注意事项。
Deep well anode bed is used in many steel pipeline cathodic protection projects in complex circumstances owing to its advantages such as less occupied area, uniform protection potential and relative small grounding resistance. On the other hand, deep well anode has the disadvantages such as higher one-time investment, complicated installation work and needing successful installation in one time, which bring forward higher requirements for installation and construction. The matters needing attention in deep well anode instal-lation are described with respects to anode well locating, well digging method selection, putting anode into well, backfill and grounding resistance measuring.2009,06(06): 39-40 收稿日期：2008-12-2分类号：TG174.41作者简介：杨万国（1961-），男，甘肃武威人，高级工程师，注册自动化系统工程师，1981年毕业于兰州石油学校自动化仪表专业，后在职依次取得专科、本科学历，现从事电气、仪表、通信、阴极保护工程施工及管理工作。
