1. Determine the installation location According to the road condition and the location of the light source, choose the direction of the light source, to meet the maximum irradiation area of the road. According to the construction drawings to survey the actual road section, verify whether the drawings and the actual match, if not, that is, stop work, report to the leadership waiting for processing, if consistent with the construction design drawings for pointing.
Points to note in the process of laying out.
A. Solar street light solar street light installation video must be installed in sufficient light and solar panels above the light-facing surface throughout the day without blocking shadows. Installation location and trees, manhole covers and other fixed facilities conflict, should be appropriately moved to the deployment point, position within 8 meters to avoid facilities, and
B. Installation location clearly marked underground fiber optic cable, cable, water pipe, overhead trees, high-rise shade, should be appropriately moved to the deployment location within 5 meters to avoid pipelines, such as can not be avoided, then apply for the use of manual excavation of the excavation pit and reported to the leadership of the processing; solar street light installation method
C. installation location above the high-voltage lines, overhead power lines, should be canceled this standing light point and can not lay the length of the road, the location of the record and reported to the company for the record.
D. There should be no direct light source above the solar panel. To avoid misidentification of the lighting control system and lead to misoperation. How to install solar street lights
E. If the installation of street lights on the side of the road next to the river, because the lights will be installed on the side without the river, so as to avoid construction caused by the loosening of the soil, easy to be washed causing landslides. Solar street light manufacturer
2. digging pits According to the construction drawings required in the location of the installed lights for excavation work, and according to the drawings to grasp the distance between the pit and the edge of the road, the width of the pit, depth, the pit can not be too wide, too shallow, and not too narrow, too deep. Mechanical excavation of the pit can be used when there are no pipelines and other facilities underground, and manual excavation must be used if there are uncertain pipelines and other facilities underground.
Precautions.
A. Survey the situation, if the surface 1.2 meters are loose soil, then the excavation depth should be deepened; excavate the pit in the position of the standing lamps and lanterns in accordance with the drawing standard, and carry out the positioning of the pre-buried parts pouring.
B. After excavating the foundation pit, confirm the location of the battery box buried, to about 0.5 meters from the pole is appropriate, the area is about 3 times the area of the battery box, the depth varies according to the region, generally in 60-120CM (specific consultation with my company's technical staff).
C. From the beginning of digging to the end of the installation, if the construction section has been passed, to do blocking measures to prohibit pedestrians and vehicles to enter the construction site.
3.Pouring Foundation pre-built parts are placed in the middle of the foundation pouring pit (pay attention to keep the pre-built parts, the foundation and the original ground on the same level or the top of the screw and the original ground on the same level, one side should be parallel to the road; so as to ensure that the light pole is not deflected after erecting the end), then one end of the PVC pipe is placed at the battery box, and the other end is pierced from the upper fixed plate of the foundation parts in the foundation pouring pit about 30cm. Finally, pour it with C20 concrete. When pouring, it is better to vibrate with vibrating pump to make the concrete more even and firm, and finally grind the whole cement surface.
Cautions.
A. Seal both ends of the PVC pipe with plastic sheet or fabric before pouring to prevent the concrete from entering the pipe and causing blockage.
B. Concrete consistency should be moderate, not too thin and not too thick.
C. Incoming concrete should come appropriately according to the number of staff so as not to affect the quality of the base pouring by causing too long waiting time for concrete.
D. The pit should be prepared before pouring, such as the height of the pit, the presence of debris, and if there are pipelines in the pit should be declared in advance to the leader to do proper treatment.
E. After construction, timely clean up the residual mud and slag on the positioning plate, and clean the impurities on the bolts with waste oil, or wrap adhesive tape around the screw before pre-burying; F. During the process of concrete solidification, water should be poured regularly for maintenance, and the concrete should be completely solidified (generally 4-7 days) before the chandelier can be installed.
