The tower is an important guarantee for supporting the overhead line conductors and ensuring sufficient safety distances between the conductors, between the conductors and the towers, and between the conductors and the ground and crossing objects. Therefore, the safety of towers is of great significance to the normal operation of transmission lines. The roots of the towers are mostly buried in the soil. Due to the particularity of the geology and the limitation of the buried depth, the foundations of the current towers are mostly shallow buried, which can provide limited stability for the upper pole body. The height of the tower is large, and the upper structure is greatly affected by the wind, which is a wind-sensitive structure. If the stability of the upper structure is not enough, shaking will occur, which may cause confusion in the wires connected to the tower, and even the tower will overturn. Therefore, a reliable tower root reinforcement device is needed to reinforce the root of the tower to ensure the stability of the superstructure.
