As a widely used bridge construction technology, swivel construction can cross mountains, rivers and existing lines. With the rapid development of China's economy, swivel construction plays a more and more important role in the field of bridge construction. This paper analyzes and studies the development of construction technology of cross-line railway swivel bridge, and focuses on the basic design points of construction technology of continuous beam bridge swivel, T-shaped rigid frame bridge swivel and cable-stayed bridge swivel. At the same time, it analyzes and studies the development of construction technology. It also discusses the railway bridge swivel construction technology and the technical development of swivel bridge, summarizes the key and difficult points of technical control in the construction process in details, and finally summarizes the construction technology development of the whole railway swivel bridge, so as to provide reference for the construction of cross line railway swivel bridge.
