1. Drilling: Excavate a circular pit with a diameter of 50cm × 50cm on the selected construction site, and drill a hole with a diameter of 12cm × 300cm on the vertical ground in the pit;
2, preparation of filler: LD can be used to reduce resistance or ion release agent, and its into a thin mud;
3. Remove the electrolytic ion grounding rod from the package and check the integrity of the product.
4. Fill the bottom of the hole with the prepared slime-like filler;
5, will be connected to the electrolytic ion grounding rod into the hole, the top of the grounding rod and the bottom of the round pit flush;
6. Take out the lead-out line; use multiple strands of copper wire of not less than 35mm2 or galvanized flat steel of not less than 40mm x 4mm as the lead-out wire, and conduct crimping of the lead-out wire and the ground rod to prevent corrosion.
7. Fill the remaining filler material around the grounding rod to the top of the grounding rod at a distance of 10cm. Measure the grounding resistance. After the requirements are met, cover the grounding rod with soil.
Note: When a set of grounding rods does not meet the resistance requirements, two or more sets can be used in parallel. The spacing between the rods and the rods should not be less than 5m. The outlet wire should be a 35mm2 stranded copper wire. The lead wire and the ground rods should be pressed. Then, node anti-corrosion treatment.
