The invention discloses a hanging basket structure used in construction of a reinforced concrete arch bridge. The hanging basket structure comprises a main truss load bearing system, each of the left and right sides of the middle of the main truss load bearing system is provided with a pair of C-shaped hooks, walking devices are connected with the tops of the C-shaped hooks, the bottoms of the walking devices are located on a walking track at the top of an arch box, connecting plates are arranged on the C-shaped hooks, each of the left and right sides of the connecting plates are connected with pulling seats on the side faces of the front basket and the rear basket of the main truss load bearing system correspondingly through a plurality of cable-stayed lifting strips, an anti-roller device is arranged on the rear basket, and a lifting load-bearing screw is arranged on the main truss load bearing system. When the hanging basket structure is used, great falling in the concrete pouring process can be avoided, the angle adjustment structure of the hanging basket is relatively simple, use is convenient, and a retreat mechanism cannot affect the structure of the bridge.
