Method for adjusting overall line shape of continuous catwalk of suspension bridge
The invention relates to the technical field of bridge engineering construction, in particular to a method for adjusting the overall line shape of a continuous catwalk of a suspension bridge. The adjusting method comprises the steps that after the whole catwalk is erected, a plurality of jacks are arranged at the connecting position of each catwalk bearing cable and an anchorage; the jacks are used for carrying out tensioning or loosening of two to three strokes on the catwalk bearing cables in sequence; then a guide chain is arranged at the position, at the top of a main tower, of each catwalk bearing cable, all the guide chains are pulled manually in the same direction at the same time, and one-time overall line shape adjustment is carried out on each catwalk bearing cable in the direction required to be adjusted; adjustment is carried out continuously and alternately many times till the overall line shape of the catwalk achieves a designed line shape. According to the adjusting method, the line shape of the catwalk can meet design requirements, and the safety and convenience of construction are guaranteed.
