[0002] Cement poles refer to power transmission equipment pillars made of cement concrete, which are used to support and fix transmission lines. Cement poles are usually used in power distribution systems in urban, rural or industrial areas, and are responsible for the bearing and stabilization of transmission lines.
[0003] Rural power grids have long suffered from weak grid structures and disrepair, which has led to frequent accidents such as pole collapse and wire breakage, and burning of distribution transformers. This has not only seriously affected the safety, economy and reliability of power supply, but also caused personal electric shock casualties. In order to provide more reliable, safe and high-quality electricity to the majority of rural power grid users, the construction of rural power distribution network transformation projects has received more and more attention.

When there is a strong wind or after a long time, the cement poles may tilt. When the cement poles tilt, it is difficult to correct the tilted cement poles. Only support rods can be installed on the sides of the cement poles, but the support rods are usually not inserted too deep into the soil layer. After raining, the soil will become soft, and the support rods will lose their supporting function, which may still cause the cement poles to collapse.
