The invention discloses an anti-electric-shock street lamp working well. The anti-electric-shock street lamp working well comprises a grounding hole body adopting a plain concrete structure and a hole lid arranged above the grounding hole body, wherein a shielding steel frame is arranged at a hole opening of the grounding hole body, and a grounding wire hole and a branch wire hole which allow a grounding wire and a street lamp branch wire to enter, as well as a cable inlet and a cable outlet which allow cable trunk lines to be led in and out are further formed in the grounding hole body; the grounding wire hole is higher than the branch wire hole, the cable inlet and the cable outlet; the shielding steel frame is connected with a street lamp metal bar grounding device through the grounding wire, and the street lamp branch wire is connected with the cable trunk wire in the hole. According to the anti-electric-shock street lamp working well adopting the structure, the shielding steel frame and a shielding steel cover are arranged at the hole opening and connected with the street lamp metal bar grounding device of a street lamp through the grounding wire, so that massive electric leakage cables can be shielded, dangerous voltage is reduced, electric shock accidents are prevented, large change of the whole grounding wire is not required, and the working well has the characteristics of concise structure, low cost and the like.
