Especially on the rammed subgrade with hard soil, the grounding body needs to be pulled out from the soil at the end of the work, and a sledgehammer is used to strike the shaking mode. After several times of use, the traditional grounding electrode needs to be scrapped and replaced. Some even insert the grounding electrode into the soft soil in order to save effort, causing the grounding resistance to fail to meet the standard and losing the protective effect.
