| Abstract: | This paper introduces the construction of the new Harbin West Passenger Station elevated corridor roof truss. Under the condition of narrow construction site and vertical operation, the 68.5m span pipe truss arch uses stepping pushing sliding construction technology for high-altitude assembly at a height of about 26.8m. The application of the technology has improved the accuracy and quality of steel truss assembly and effectively shortened the construction period as well as saving the cost. |
