Development Of Plane Rotating Traction System: Based On The High-Speed Rail (72+128+72) M Continuous Prestressed Concrete Beam Bridge, Weinan Wang

Theses and Dissertations

With the advent of rotate construction techniques, it is easy to build a new bridge crossing over existing structures, rivers and valleys quickly, easily and safely. Although the general concept of the rotating method is similar for different engineering characteristics, it is necessary to make some changes, which are more in line with the requirements of the particular project. Based on a 3-spans (72+128+72)m continuous concrete bridge, this paper presents a new rotation method, the down-slide-way unbalanced rotation system, which can save time and reduce cost compared to the up-slide-way rotation method. Through the improvements of the traction system and …
