接地装置是关系到建筑物和设备以及人身安全极为重要的设施，因此当前对建筑物和广播电视塔等的防雷接地要求以及对各种用电设备的工作接地和保护接地的要求越来越严格，因而对接地工程也提出了越来越高的要求。传统的接地方法一般采用钢材直接埋入地下，这对于高土壤电阻率地 Grounding devices are extremely important facilities related to buildings, equipment, and personal safety. Therefore, there are more and more requirements for lightning protection grounding of buildings, radio and television towers, etc., as well as working grounds and protective earthing requirements for various electrical equipment. Strict, and therefore put forward increasingly high requirements for grounding projects. The traditional grounding method generally uses steel directly buried underground, which is for high soil resistivity
