However, the traditional three-plate foundation has low bearing capacity, no reliable connection with the tower, and poor coordination. On the other hand, the construction excavation volume is large, the construction period is long, and the construction quality is difficult to guarantee. In addition, due to the complex terrain and geological conditions, the design and construction of conventional transmission line foundations are often subject to various constraints. Therefore, it is of great significance to carry out research and application of tower foundations.

[0003] The micro pile foundation of the ring pole tower is a foundation used to improve the bearing capacity of the ring pole tower. During the long-term operation of the distribution line, due to the influence of factors such as strong winds and uneven foundation settlement, most of the distribution lines have tilted to varying degrees.
