The construction quality of the sidewalk is poor, and the ground sinks, which causes the cable to be deformed by force, resulting in cable armoring. After the cable head is wrapped, most of the doors cannot be closed. In addition, the advertising industry has developed rapidly in recent years, and the advertising load is also connected to the courtyard accordingly. With the continuous development of urban construction, courtyard lights continue to extend. Especially in the northeast region, which is in the high-cold zone, the winter comes, making the cables and soil form a whole.

Mainly manifested in the following points: First, the depth of the cable trench is not enough, and the sand-covering bricks are not constructed according to the standard; The second is that the production and installation of the aisle pipe do not meet the requirements, and the two ends are not made into horns according to the standard; The third is dragging on the ground when laying cables; Fourth is that the embedded pipes of the foundation are not constructed according to the standard requirements.

In the foundation, the upper surface of the buried ground cage must be level (measure and test with a level), and the anchor bolts in the ground cage must be perpendicular to the upper surface of the foundation (measure and test with a square); before installation, two threading pipes The end must be blocked to prevent foreign objects from entering or blocking during or after installation, which may cause difficulty in threading or unable to thread during installation; the soil around the foundation must be compacted; the solar LED street light foundation needs to be maintained for 2 to 7 days after the production is completed (determined according to weather conditions ); The installation of solar led street lights can only be carried out after the foundation of solar led street lights has passed the acceptance.

Before designing the installation layout of solar LED street lights in a certain place, designers must carefully inspect the surrounding environment of the installation site to avoid unreasonable installation sites. If there is groundwater seepage, immediately stop the installation process; the bottom of the tank where the battery compartment is placed in the foundation must be equipped with drainage holes or according to the requirements of the drawings.
