Grounding device convenient to construct

The grounding device comprises a steel grounding rod, the outer wall of the steel grounding rod is plated with a metal composite layer after the steel grounding rod is subjected to phosphating treatment, and the metal composite layer comprises 55% of copper, 35% of silver, 8% of nickel and 2% of silicon. The grounding device is formed by compounding a plurality of metal materials, the interior of the grounding device is a steel pipe with extremely high rigidity and toughness after processing, and the surface of the grounding device is a composite layer formed by spraying and firing copper, silver, silicon and nickel metals, so that the electrical conductivity and the thermal conductivity are enhanced, the corrosion resistance of the material is improved, a grounding rod is tamped into the ground through a knocking method and is vertically grounded, and the depth can reach 60 meters; the resistance is reduced by deeply utilizing the humidity of soil, the effect is obvious, the resistance value is stable, earth
