摘　　要：研究共结构双层内衬改造技术,其结构共由5层组成,分别为基础层(防腐层和加强密封层组成)、中空监测层、内衬加强层、防油防腐层和导静电层。采用该技术对加油站埋地单层钢制油罐进行改造,经过罐内清洗、喷砂除锈、基础层施工、中空监测层施工、内衬加强层施工、防油防腐层施工、导静电层施工和整个系统气密性的保压检测,圆满完成了双层内衬油罐的现场改造。采用GB30040规定的Ⅰ级真空泄漏监测方法,可以在油品泄漏前报警,实现埋地油罐整体安全水平的提升,具有重要的现实意义。The research object of this article is a co- structural double wall lining reform technology, whose structure is consist of basic layer （ anticorrosion layer and strengthening sealing layers）, hollow moni- toring layer, reinforced lining layer, geese proofing layer and electricity conducting layer. Then we use this technology to modify a single wall underground steel storage tank, through tank cleaning, sandblast- ing, building of basic layer, hollow monitoring layer, reinforced lining layer, grease proofing layer, elec- tricity conducting layer and tightness pressure detec- ting of the whole system, the modification of the on site internal lining double wall tank was succeed. In this paper, we talked about the total structure of the double wall lining reform technology using level I leak detection method in GB30040 -vacuum leak de- tection that can alarm before the oil spill, which en- hance the overall safety level of underground storage tank. It is of great practical significance.
