Three-span variable-height steel-concrete mixed continuous beam construction method
The invention relates to the technical field of bridge construction, in particular to a three-span variable-height steel-concrete mixed continuous beam construction method which comprises the following steps: firstly, constructing a NO. 0 block of a steel-concrete mixed continuous beam; after completion, symmetrically pouring first to eighth hanging basket cantilevers; after completion, hoisting asteel-concrete combined section; during hoisting, arranging a rhombus hanging basket at the position of an eighth poured beam body section, arranging a hoisting platform on the rhombus hanging basket, wherein the hoisting platform is provided with four hydraulic lifters, and the four hydraulic lifters are used for hoisting the steel box girder of the steel-concrete combined section to a mountingposition of the steel box girder from a river middle girder transporting ship; after the steel box girder is hoisted in place, creating a steel-concrete combined section reinforced concrete structureof the girder section, so that a steel-concrete combined section is formed; removing the temporary lock of the NO. 0 block; constructing a mid-span closure section and forming the three-span variable-height steel-concrete mixed continuous beam. The invention has the advantages that hoisting time is short, the traffic can be opened after the vehicle is in place, the temporary occupation time of roads and navigation channels is shortened, and the adverse effect on social traffic is reduced.
本发明涉及桥梁施工技术领域，尤其是一种三跨变高度钢‑砼混合连续梁施工方法，首先施工钢‑砼混合连续梁的0#块；完成后对称浇筑1‑8#挂篮悬臂；完成后对钢‑砼结合段进行吊装，在吊装时在已浇筑的8#梁体节段位置设置菱形挂篮，所述菱形挂篮上设置有吊装平台，所述吊装平台具有四台液压提升器，四台所述液压提升器用于将所述钢‑砼结合段的钢箱梁自河中运梁船吊装至其安装位置；所述钢箱梁吊装就位后施工该梁段的钢‑砼结合段钢筋混凝土结构从而形成钢‑砼结合段；拆除0#块的临时锁定；中跨合拢段施工；形成三跨变高度钢‑砼混合连续梁。本发明的优点是：吊装时间短，就位后即可开放交通，缩短道路及航道的临时占用时间，减小对社会交通的不利影响。
