Erecting method for slippage supporting structure of extra-large steel bridge section
The invention discloses a method for erecting a slippage supporting structure of an extra-large steel bridge section, which is characterized in that the slippage supporting structure formed by combining steel pipe piles and Bailey longitudinal beams is adopted, and the method specifically comprises the steps of steel pipe pile construction, parallel connection of the steel pipe piles and inclined struts, hoisting of the Bailey longitudinal beams, installation of a reinforcing supporting frame, a lateral limiting frame, a sleeper beam and a track beam, overload prepressing and the like. Compared with the prior art, the sliding supporting structure is large in bearing capacity, capable of meeting sliding construction of an extra-large steel bridge section, simple in structure, high in assembly efficiency and convenient to manufacture and install, the number of supports erected at a bridge site is small, the field installation period is greatly shortened, the influence of unfavorable environments such as strong wind and rain is small, and the welding quality of the steel box girder is further guaranteed; efficient and high-quality erection of the ultra-wide separated steel box girder of the extra-large cable-stayed bridge is ensured, the goals of economy, reasonability, high efficiency and safety are achieved, and the method has good application prospects.
本发明公开了一种特大钢桥梁段滑移支撑结构的搭设方法，其特点是采用钢管桩与贝雷纵梁组合的滑移支撑结构，具体搭设包括：钢管桩施工、平联钢管桩及斜撑、吊装贝雷纵梁、安装补强支撑架、侧向限位架、枕梁、轨道梁和超载预压等步骤。本发明与现有技术相比具有滑移支撑结构承载力大，可满足特大钢桥梁段的滑移施工，结构简单，装配效率高，制作安装便捷，桥位搭设的支架量少，大大缩短了现场安装工期，受大风、雨等不利环境的影响小，钢箱梁焊接质量得到了进一步保证，确保了特大斜拉桥超宽分离式钢箱梁高效、高质量架设，实现了经济合理及高效安全的目标，具有良好的应用前景。
