Zusammenfassung: | The invention discloses a vertical deep drilling well landfill type grounding body installation method. The method includes the steps that step 1, a vertical well is drilled; step 2, a vertical grounding body is put into the vertical well; step 3, soil or a resistance reducing agent is guided into the vertical well; step 4, tamping is conducted by using a filler tamping device; and step 5, the upper end of the grounding body is welded to and linked with a neutral point line of a distribution transformer. Therefore, the technical problems that in the prior art, a vertical grounding body adopts a 'forced insertion type' grounding mode, the vertical grounding body possibly meets a rock layer or a relatively hard soil layer and cannot be hit into the ground in the process of hitting into the ground, and the grounding resistance cannot be effectively reduced are solved.
