11# On the morning of March 9 , the first steel box girder of ramp H , bid 4 of Luoyang Torch Avenue, manufactured and organized by Metal Structure Company, was successfully hoisted, marking the formal entry of the steel box girder construction phase of ramp H of the interchange between Torch Avenue and Luoyi Expressway.
It is reported that our company has undertaken the manufacturing and installation of steel box girders for the three parts of H ramp, J ramp and DF ramp of Torch Avenue Project, totaling more than 1800 tons of steel box girders. The H ramp steel box girder installed this time has a total length of 149 meters and a bridge deck width of 9.05 meters. It is divided into 4 spans and consists of 24 cantilever plate boxes and 1 transverse box. The steel box girder is manufactured by the metal structure company in the factory of the bridge base, and after passing the acceptance of the owner and the supervisor, it is transported to the site for hoisting and splicing in sections. The steel box girder hoisted at is H 0 -A ~ H 0 -C section box, with a total weight of 193.4 tons and a length of 33.126 meters. A 160-ton truck crane completes the hoisting operation in sections.
The ramp steel box girder was manufactured and installed on site for the first time by the metal structure company. In order to complete the hoisting task with high quality, the first shot of Yu 'an steel box girder brand was fired. Before hoisting, the production department held several special meetings to repeatedly discuss the hoisting scheme and ensure safety through expert and supervisor demonstration. At the project site, after detailed safety and technical disclosure to the participating operators, all preparations are ready. With the commander's order, the steel box girder is slowly lifted and hoisted in place according to the established plan. After the hoisting is completed, the surveyor enters the site to review the hoisting position of the steel box girder to ensure that the installation position of the steel box girder is accurate. The successful placement of
first span steel box girder has laid a good start for the installation of the remaining steel box girder of the ramp, and the remaining steel box girder will also be hoisted in sequence on this basis. Next, the metal structure company will continue to make every effort to promote the hoisting and welding construction of the remaining steel box girders to ensure high standards and high quality to complete various tasks.
