基于导电混凝土技术的接地设计

Grounding Design Based on Conductive Concrete Technology

笔者介绍了导电混凝土技术现状、相关材料及制备;分析了导电混凝土的原理及制备流程,并依托110 k V太汉线迁改工程,积极运用导电混凝土基础自然接地,取消人工接地敷设,实现基础工程与接地工程同步完成。通过与常规接地方式比较,导电混凝土基础自然接地方式降阻效果较好,极大地减少接地施工开挖面积,降低了因征地及青苗问题造成的阻工风险,方便施工单位施工。

This paper introduces the present situation,related material,fabrication process and principle of conductive concrete technology.Taking the 110kV T ai-H an Transmission Line Relocation Project as an example,the artificial laying grounding method is replaced by the natural conductive concrete foundation grounding method,which achieves foundation works and grounding works are completed at the same time.Compared with the conventional grounding method,the conductive concrete foundation grounding method can effectively reduce the resistance,decrease excavation area of grounding construction,lower the delay risk caused by land expropriation and crop problems and provide convenience for construction.
