Abstract

Provided is a suspension bridge catwalk-free construction method. A rigid portal frame is installed on the top of each cable tower, two bearing cables are erected through the rigid portal frames, the bearing cables are located above a suspension bridge main cable, the two ends of each bearing cable are fixed to suspension bridge main cable anchors, hanging baskets are hung on the bearing cables and move back and force between the cable towers of the two shores through control of traction cables, and main cable pulling and cable clamp and hanger rod installing are achieved.

Description

technical field [0001] The invention relates to a construction method for a suspension bridge without a catwalk, in particular to a construction method that does not need to erect a construction catwalk and only uses load-bearing cables, traction cables and hanging baskets to install the main cables, cable clips and suspension rods of the suspension bridge. Background technique [0002] At present, the construction of suspension bridges mostly uses construction catwalks to install main cables, cable clips and suspenders. When adopting construction catwalk to carry out construction, the construction of construction catwalk itself is complicated, and construction period is long, and cost is high. Contents of the invention [0003] In order to overcome the shortcomings of suspension bridges using construction catwalks, the present invention provides a construction method without catwalks. The construction method is to install the main cable of the suspension bridge by erectin...
