1. Determine the position of standing lamp; According to the geological survey, if the surface 1m 2 is soft soil, the excavation depth should be deepened; At the same time, it shall be confirmed that there are no other facilities (such as cables, pipelines, etc.) below the excavation position, and there are no long-term shading objects on the top of the street lamp, otherwise the position shall be changed appropriately.
2. Reserve (excavate) 1m 3 pits meeting the standards at the position of vertical lamps; Carry out positioning and pouring of embedded parts. The embedded parts are placed in the middle of the square pit, one end of the PVC threading pipe is placed in the middle of the embedded parts, and the other end is placed in the storage place of the battery (as shown in Figure 1). Pay attention to keep the embedded parts and foundation on the same level as the original ground (or the top of the screw is on the same level as the original ground, depending on the needs of the site), and one side should be parallel to the road; In this way, it can be ensured that the lamp post is upright without deflection. Then, C20 concrete shall be poured and fixed. During the pouring process, the vibrating rod shall not be stopped to ensure the overall compactness and firmness.
3. After construction, the residual sludge on the positioning plate shall be cleaned in time, and the impurities on the bolts shall be cleaned with waste oil.
4. In the process of concrete solidification, watering and curing shall be carried out regularly; The chandelier can be installed only after the concrete is completely solidified (generally more than 72 hours).
