Development of Plane Rotating Traction System: Based on the High-speed Rail (72+128+72) m Continuous Prestressed Concrete Beam Bridge
Abstract
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 the travel system, the rotation construction period and cost-effectively saved, yet the construction quality is still guaranteed. The construction
technology of this new method will also reduce construction risks and simplify the process.
