How deep is the concrete pier of solar lamp?

Generally, it should be below the frozen soil, 1.5m in the north and 1.2m in the south.

Pay attention to this question:

1: Influence of geology on foundation depth

Different geology has different forces on the embedded parts of solar lamp poles, and the pressure they can bear is also different. Therefore, the construction designer will determine the ratio of the embedded height to the exposed height of the light pole according to the softness of the geology, so as to ensure that the solar street lamp will not shake or topple.

2. Influence of geographical location on buried depth

The wind is strong in mountainous areas, and solar street lamps will produce greater wind resistance. Therefore, the solar street lamps erected in mountainous areas and open spaces are far more buried than those in urban buildings. The reason is that the stability of solar street lamps will be affected even if the wind resistance caused by solar street lamps and poles in open air is to be resisted.
