The PC circular foundation of a street lamp forming in the outside is inserted into the excavation hole formed on the ground. A conductive concrete grounding layer is installed on the bottom of the PC circular foundation of a street lamp. At least one foundation reinforcing bar is inserted into the PC circular foundation of a street lamp. The front end of the foundation reinforcing bar is connected with the anchor bolt and the other end thereof is connected with the conductive concrete grounding layer. The conductive concrete grounding layer is electrically connected with the anchor bolt around which a grounding wire is bound. |
