1、钻孔:在选好的施工场地开挖直径50cm×50cm垂直地面的圆坑或方坑,在坑里钻出直径12cm×300cm垂直地面的孔洞;

 

2、配制填充料:可使用LD降阻剂或者离子缓释剂,将其和成稀泥状;

3、将铜包钢接地棒从包装中取出,检查产品是否完整。

4、将配制好的稀泥状填充料填入孔洞底部;

5、将接铜包钢接地棒植入孔洞中,接地棒顶部与圆坑的底部平齐;

6、接好引出线;引出线采用不小于35mm2的多股铜线或不小于40mm×4mm的镀锌扁钢,引出线与接地棒体实行压接,接点防腐处理;

7、将其余填充料填在接地棒周围至接地棒顶端10cm时止,测量接地电阻,达到要求后,用土填盖在接地棒周围。

1. Borehole drilling: excavate round or square pits with a diameter of 50 cm x 50 cm on the vertical ground in selected construction sites, and drill holes with a diameter of 12 cm x 300 cm on the vertical ground in the pits;
 
 
 
 
2. Preparing filling material: LD drag reducer or ion slow-release agent can be used to make it into dilute mud.
 
 
 
3. Remove the copper clad steel grounding rod from the package to check whether the product is complete.
 
 
 
4. Fill the prepared slurry filling material into the bottom of the hole.
 
 
 
5. Implant the copper-clad steel grounding rod into the hole, and the top of the grounding rod is level with the bottom of the pit.
 
 
 
6. Connect the lead-out wires well. The lead-out wires are made of multi-strand copper wires not less than 35 mm2 or galvanized flat steel less than 40 mm x 4 mm. The lead-out wires are pressed with the grounding rod body and the contacts are anticorrosive.
 
 
 
7. Fill the rest of the filler around the grounding rod until the top of the grounding rod is 10 cm. Measure the grounding resistance. After meeting the requirements, fill it with soil around the grounding rod.
