The cable 5 is pulled from the north shore to the south shore of the suspension bridge to simultaneously pay off the head and tail ends of the same cable 5, as shown in fig. 2, in order to ensure that the head and tail ends of the cable 5 are parallel to pay off, the stress direction of the cable 5 is optimized, a plurality of guide brackets are further arranged, and the head and tail ends of the cable 5 respectively pass through the guide brackets in sequence and are then adjusted to be in a parallel position relationship. After the cable is put, the middle part of the cable 5 is anchored in the rotary anchorage structure 9. The rotary anchor structure 9 is provided with a rotary cable saddle for balancing the stress condition of the middle part of the cable 5.
Because the steering frame of the traditional rotary cable needs to realize the rotation after one end of the cable 5 continuously passes through the rotary anchorage, but because the length of the cable 5 of the rotary cable is longer than that of the traditional cable 5, the corresponding steering operation process is difficult, the time cost of the steering frame is longer, and the mode of simultaneously pulling the two ends of the head and the tail of the same cable 5 to pay off is adopted, so that the cable paying off time can be greatly shortened, the cable paying off efficiency is improved, and the operation of continuously passing one end of the cable 5 through the rotary anchorage structure 9 to finish the steering is avoided, and the construction difficulty is reduced.
