I. Pre - installation Preparations
Tools and Materials List
1.Street Lamp Components: Lamp poles (Select appropriate specifications according to the designed height, usually made of steel), lamps (LED lamps are common, determine the power and lighting angle), lamp shades, and lamp bases.
II. Foundation Construction
Foundation Pit Excavation
1.Determine the size of the foundation pit according to the height and weight of the lamp pole. Generally, for 8 - 12 - meter - high street lamp poles, the depth of the foundation pit is 1.5 - 2 meters, and the side length of the bottom of the pit is 1 - 1.5 meters (square foundation pit). Use a shovel or a small excavator for excavation to ensure that the pit walls are vertical and the pit bottom is flat. If underground pipelines are encountered during the excavation process, stop the operation immediately, communicate with relevant departments, and take protective or avoidance measures.
2.Lay a 10 - 15 - centimeter - thick gravel or sand cushion at the bottom of the pit, and compact it with a plate vibrator to enhance the bearing capacity of the foundation.
Steel Bar Binding and Anchor Bolt Installation
1.Bind the steel bar framework in the pit according to the design requirements. The steel bars should be evenly spaced, and the intersection points should be firmly bound with iron wire to enhance the integrity and stability of the foundation.
2.Fix the anchor bolts on a customized bolt positioning template, adjust the bolt spacing and verticality to accurately match the bolt holes of the lamp pole bottom flange. The length of the anchor bolts exposed above the ground is determined according to the lamp pole installation requirements, generally 10 - 15 centimeters. Wrap the exposed part with plastic film to prevent the threads from being contaminated during concrete pouring. Then weld the positioning template and the steel bar framework to ensure that the position of the anchor bolts remains unchanged during the pouring process.
Formwork Erection and Concrete Pouring
1.Erect the foundation formwork. The formwork can be made of steel or wood. It is required to be tightly spliced and firmly supported to prevent grout leakage and deformation during concrete pouring. The size of the formwork is slightly larger than that of the foundation pit for convenient construction.
2.Mix the concrete according to the concrete mix ratio (for example, cement : sand : gravel = 1:2:3), ensure uniform mixing and that the slump meets the requirements. Slowly pour the concrete into the foundation pit, and at the same time, use a vibrating rod to vibrate it to expel the air bubbles in the concrete and make the concrete compact. During the pouring process, check the position of the anchor bolts at any time and adjust them in case of deviation.
3.When the concrete is poured to about 5 - 10 centimeters from the ground, use a level to level the top surface of the foundation to ensure that the foundation is horizontal. After the concrete begins to set, finish the surface of the foundation to make it smooth and prevent water accumulation.
III. Lamp Installation
Lamp Assembly
1.Assemble the components of the lamp on the ground, such as installing the lamp shade, fixing the lamp base, and connecting the light source. Check whether the appearance of the lamp is damaged and whether the components are firmly connected.
2.Fit the clamp to the light pole, insert bolts, then tighten gradually in a diagonal order with moderate force to prevent damage to integrated components;
Installing the Lamp on the Lamp Pole
1.Gently shake the clamp to confirm no looseness, check the distance from the street light's integrated circuits and equipment, ensuring firm installation without interfering with overall functionality.
IV. Electrical Connection
Wiring in the Lamp Pole
1.Align with the pole's curvature, fit the arc-shaped support to the preset position on the pole, and calibrate its fit with the clamp; Insert bolts to fix the support and clamp, tighten diagonally to prevent loosening, and fit the integrated street light structure; Gently shake to check for no displacement, ensure the support is stable, and that it does not affect the street light's integrated functions.
V. Lamp Pole Installation
Lamp Pole Lifting
1.Select a crane with an appropriate tonnage. Park the crane on a flat and solid ground to ensure that the crane outriggers are stable and the operating radius meets the lamp pole lifting requirements. Check the crane boom, hook, ropes and other components to ensure they are safe and reliable.
2.Tie the lifting ropes at a suitable position on the top of the lamp pole. The ropes should be evenly distributed and have sufficient strength to prevent the lamp pole from tilting during lifting. Slowly lift the crane boom to lift the lamp pole to a certain height, and move the crane to align the bottom of the lamp pole with the anchor bolts in the foundation pit.
3.Lower the lamp pole to align the bolt holes of the lamp pole bottom flange with the anchor bolts, and initially tighten the nuts, but do not fully tighten them for subsequent adjustment of the lamp pole verticality.
Lamp Pole Verticality Adjustment
Measure the verticality of the lamp pole from multiple directions (at least two mutually perpendicular directions) to ensure that the lamp pole is perpendicular to the ground in all directions. After the adjustment is completed, tighten the nuts according to the specified torque (for example, the torque of 8.8 - grade bolts is 200 - 250N•m) to fix the lamp pole.
VI. Commissioning and Maintenance
Commissioning
1.After the street lamp installation is completed, check whether all electrical connections are correct and firm, whether the lamps are stably installed, and whether the verticality of the lamp poles meets the requirements.
2.Close the switch in the distribution box to conduct a power - on commissioning of the street lamps. Check whether the lamps are lit normally, observe whether the brightness and color of the lamps are uniform. If there are lamps that do not light or have abnormal light emission, troubleshoot the faults in a timely manner. Possible causes include lamp damage, loose wire connections, and blown fuses.
3.Check the street lamp control system, such as whether the time - controlled switch accurately turns on and off the street lamps according to the set time, and whether the photosensitive controller can automatically control the on - off of the street lamps according to the ambient light. If there are problems, adjust the control system parameters or replace the faulty components.
