FXI-25 Nano Carbon Composite Anti Corrosion Galvanized Flat Steel HFDJ1-50-3-1 Composite Anti Corrosion Grounding Electrode

Description :

　　(1) The burial depth of the nano carbon carbon composite anti-corrosion grounding device should not be less than 0.8m at the top

　　(2) The buried position of the nano carbon carbon composite anti-corrosion grounding device should not be less than 1.5m away from the building. When encountering buried grounding bodies such as garbage and ash, the soil should be replaced and compacted layer by layer.

　　(3) When the nano carbon carbon composite anti-corrosion grounding device is connected by welding, the weld seam at the welding point should be full and have sufficient mechanical strength, without defects such as slag, bite, cracks, virtual welding, and pores. After knocking and cleaning the coating at the welding point, apply anti-corrosion special coating for anti-corrosion treatment.

　　(4) Drill holes at the location of the grounding body according to the design and insert the grounding body. The installation of the grounding body is strictly prohibited from using the tapping installation method. After the grounding body is installed into the installation hole (well), the backfill soil should not contain stones or construction waste, and should be compacted layer by layer during backfilling.

　　(5) Fill and compact with soil to ensure close contact between the grounding body and the soil, leaving about 20cm at the upper end for connection with the horizontal grounding wire, and conduct inspection.

　　(6) Laying of horizontal grounding wires connecting grounding bodies; Before laying, it should be straightened, and then the grounding wire should be placed in the trench. The horizontal wiring should be connected to the grounding electrode using the designed connection method in sequence. The flat grounding wire should be placed on the side rather than flat. When connecting by welding, the welding slag should be removed after welding, and the surface anti-corrosion coating should be applied to the welded and damaged parts using the process method specified by the factory. Leave sufficient connection length for use at the location where the grounding wire needs to be led out.

　　(7) The exposed grounding wire should be painted black, and the paint should be uniform without any omissions, but the terminal clamps and grounding terminals should not be painted.

　　(8) After the connection is completed, the quality supervision department should be promptly requested to conduct a hidden inspection (material, position, welding quality, section specifications, etc.), which should meet the design and construction acceptance requirements. Only after passing the inspection can backfilling be carried out, layered compaction should be carried out, and the grounding resistance shake test value should be recorded on the hidden inspection record sheet.
