70m平面曲线半径连续梁节段拼装架桥机优化设计及施工关键技术

Optimization Design and Key Construction Technique of Bridge Girder Erection Machine for Continuously Assembled Segments Deck with 70m Plane Curve

基于澳门轻轨项目,结合70m平面曲线半径连续梁节段拼装架桥机研究和应用,分析了小半径曲线弯道架梁技术难点,提出小半径节段梁拼装技术难点解决方案及工艺创新,总结形成一套小半径节段梁拼装施工关键技术。

Based on the light rail project in Macao, combined with the research and application of a 70 m plane curve radius continuous beam segment assembly and gantry machine, the technical difficulties of the smallradius curved girder erection were analyzed, and the solution of technical difficulties and technological innovations for the assembly of small radius segmental beams were proposed. This paper summarized the formation of a key technology for the assembly of a small radius section beam.
