Nanning Cloud—Nanning News Network (Reporter Li Qin, Correspondent Meng Ting, Chen Jianrong) On July 6, as the last box beam fell accurately on the 3# abutment on the left side of the upper span G242 mid-bridge, the 312 box beam erection task of the Nanheng Expressway Seven-Phase Project under the responsibility of China Railway Beijing Engineering Bureau was completed 30 days ahead of schedule. At this point, the Nanheng Expressway Project civil engineering has been fully connected.
Nanheng Expressway Gear Erection has been completed. The seventh standard project of
Nanheng Expressway is located in Qingxiu District, Nanning City, Yongning District, and Hengzhou City. It has a total line of 9.58 kilometers, 5 bridges, and 312 box girder erections. This section is the first section on the entire project to complete the box girder erection task.
upper span 242 middle bridge box girder construction site.
"This time, the first box girder erection task was completed on the whole line. It is another new result achieved by the project department after taking the lead in completing the first box girder casting and the first box girder prefabrication of the Nanheng Expressway. The project will continue to strive to overcome the remaining bridge deck system and ancillary projects construction tasks to ensure that progress and quality meet both standards." According to Guo Zhanhong, head of the Nanheng Expressway Project Department of China Railway Beijing Engineering Bureau, since the box girder erection, the project department of this section has taken the initiative to face difficulties and seize effective implementation Working time, under the climate conditions of high temperature and sultry, heavy rainfall and long duration in the south, many difficulties such as bridge curve radius, large vertical and cross-slope (4%), high risk coefficient, long distance and many obstacles, large construction cross-interference, tight time and heavy tasks. Through reverse construction period, refine nodes, optimize construction plans, strengthening construction technical briefing, opening up beam rigging channels, and fully equipped beam rigging personnel, the construction organization and process control have been continuously strengthened. At the same time, full-time safety production management personnel are arranged to supervise the entire process, and the equipment technical performance and safety device pre-operation inspection work is carried out to ensure that the safety and quality of the box girder erection process is fully controlled and that the box girder erection work is carried out in an orderly manner.
Nanheng Expressway is a newly built eight-lane highway in Guangxi. It is a major project for the construction of Dongrong Road in Guangxi. The line is 110 kilometers long, with a designed speed of 120 kilometers per hour and eight-lane in both directions. It is planned to be completed and opened to traffic by 2023. After completion, it will be of great significance to improving the integrated development level of Beibu Gulf Urban Agglomeration and strengthening the radiation and driving role of Nanning.
