[0002] Transmission towers are the core structural support for transmission lines, playing a crucial role in ensuring stable power transmission. Currently, traditional transmission towers mostly use cast-in-place foundations. These foundations require on-site manual formwork erection, reinforcement binding, pouring, and curing, necessitating a large workforce, complex construction methods, significant workload, and a long construction period. Furthermore, the types and dimensions of tower foundations vary greatly depending on the circumstances, requiring extensive formwork fabrication. Moreover, construction quality is unpredictable due to unstable factors such as the site environment and weather. Therefore, designing and providing a modular, prefabricated variant foundation for transmission towers is extremely urgent. Utility Model Content

[0026] The installation and use process of the combined prefabricated variant foundation for transmission line towers of this utility model is as follows:
