[0025] 3. After confirming the successful docking of the two concrete poles, the first flange ring 6 is fitted over the male pole 4 and the second flange ring 7 is fitted over the female pole 5, ensuring that the flange rings are tightly attached to the surface of the concrete poles and are correctly positioned, then the entire structure is fixed by passing the high-strength bolts 8 through the corresponding mounting holes on the first and second flange rings 6 and 7, and each bolt is tightened using a torque wrench according to the specified torque value to ensure that the joint has sufficient strength and stability.
[0026] After completing the above steps, the first concrete pole 1 and the second concrete pole 2 are successfully and stably connected, and this segmented modular design not only simplifies the logistics process and reduces transportation costs, but also allows for quick assembly on site, reducing the need for large lifting equipment.
