[0022] The present invention will be further described below with reference to the drawings and examples.
[0023] 1. Set up a catwalk on a vertical surface
[0024] Such as Picture 10 with Picture 11 As shown, the catwalk 1 is composed of catwalk load-bearing cables, beams, handrail cables, surface nets, lateral wind-resistant stabilizing cables 7, and anchoring adjustment systems. The catwalk load-bearing cable 1 can use a three-span separation structure. Set up a combined catwalk on each side. Since the mid-span main cable needs to go through a space conversion process, the mid-span catwalk adopts two independent catwalks.
[0025] 2. Vertical surface braided cable
[0026] The main cable 2 is set above the catwalk 1, and the vertical plane erection technology of the main cable unit strands is relatively mature, which is divided into two types: general strand erection and reference strand erection. The main construction steps are: cable strand traction; cable strand lifting, ...
