This invention discloses the structure and construction method of an arch bridge viewing platform. The specific structure includes a main beam, with prefabricated platform sections symmetrically arranged on both sides of the main beam along the bridge's centerline. The outer walls of the prefabricated platform sections are connected to cantilevered splicing sections. The ends of the two cantilevered splicing sections furthest from the bridge's centerline coincide with the ends of the main beam. End caps are provided at the ends of the main beam. The inner walls of the prefabricated platform sections are connected to main arch ribs. This invention's arch bridge viewing platform structure solves the problem of poor overall structural integrity in existing arch bridge viewing platforms. The construction method of this invention is simple to operate and allows for rapid construction.

The utility model belongs to the technical field of underground diaphragm wall construction equipment, and discloses a simple construction tool basket for underground diaphragm wall construction, a bottom plate is positioned at the bottom of the tool basket, a main body reinforcing steel bar frame comprises two U-shaped reinforcing steel bars and a plurality of supporting reinforcing steel bars welded between the U-shaped reinforcing steel bars, and the lower ends of the two U-shaped reinforcing steel bars respectively penetrate through reinforcing steel bar penetrating holes in the two ends of the bottom plate; the side doors are movably mounted at two ends of the main reinforcement frame through bolts; the safety rope fixing anchor point comprises a plurality of safety rope hooks fixed at the upper end of the main body steel bar frame; and each lifting point comprises an inclined reinforcing steel bar welded at the corner position of the main body reinforcing steel bar frame.
