1. The poles, lamp panels, wiring, and lifting and lowering motor mechanisms of mid-pole lamps and high-pole lamps should comply with the current industry standard "Technical Conditions for High-Pole Lighting Facilities" (CJ/T3076-1998). Structure of medium and high pole lighting facilities. 2. Three-phase power supply should be used for mid-pole lights and high-pole lights, and the three-phase load should be evenly distributed, and protection devices must be installed in each circuit. 3. Stakes should be provided for the top elevation of the foundation. 4. The excavation depth and size of the foundation pit shall comply with the design regulations. The allowable deviation of the depth of the foundation pit should be ten 100mm, -50mm. When the deviation between the foundation pit depth and the designed pit depth is more than 100mm due to soil quality reasons, it should be handled according to the following regulations: (1) When the deviation is +100mm and -50mm, paving and grouting should be used. (2) When the deviation exceeds +300mm of the specified value, the part exceeding +300mm can be tamped with soil or sand or stone. Then use paving stone grouting treatment. The concrete foundation of the high pole light is shown in the drawing. 5. The length of the anchor bolts buried in the concrete should be greater than 20 times its diameter, and should be welded firmly with the main reinforcement. The anchor bolts should be removed from rust, and the threaded part should be protected. The diameter of the center of the flange holes should be the same, and the deviation should be smaller than that of the bolts. Double nuts and spring washers should be used. 6. The formwork for pouring concrete should be made of steel formwork. The surface should be flat and the joints should be tight. The formwork should meet the requirements of the design size of the foundation. Before the concrete is poured, the surface of the formwork should be coated with a release agent.
