大矢跨比钢箱拱肋拼装施工关键技术研究

钢拱桥造型奇特形式优美,深受各位工程师的青睐,也是各位学者的热点研究对象。该文以石家庄市复兴大街市政化改造泊水湾公园特大桥项目为例,对钢拱肋的拼装施工关键技术进行研究,主要包括钢拱肋拼装施工的临时支架措施、钢拱肋拼装施工的起重设备选择和钢拱肋拼装施工的吊装。在整个拼装过程中,要保证构件对接口的精度问题,尽量避免在后面的提升施工中出现无法与拱脚进行顺利对接的情况,为相关工程的施工提供可靠建议。

Steel arch bridge has a unique shape and beautiful form,which is favored by all engineers,and it is also a hot research object of scholars.Taking the urbanization reconstruction of Boshui Park Bridge in Fuxing Street of Shijiazhuang City as an example,this paper studies the key technologies for the assembly and construction of steel arch ribs,which mainly include the following points,temporary support measures for the assembly construction of steel arch ribs,the selection of lifting equipment for the assembly construction of steel arch ribs for the hoisting of steel arch rib assembly construction.In the whole assembly process,it is necessary to ensure the accuracy of the interface of the components,and try to avoid the smooth docking with the arch foot in the later lifting construction,which provides reliable suggestions for the construction of related projects.
