Rapid construction structure and construction method for overline steel bridge
The invention provides an overline steel bridge rapid construction structure and a construction method.A steel-concrete combined system is adopted, an overline bridge is divided into a front overline steel bridge and a rear overline steel bridge according to coming and going lanes, the middle section of a steel box girder penetrates through the position over an expressway, and one side of the steel box girder is connected with a cast-in-place concrete beam section on one side through a steel-concrete combined section; the other side of the steel box girder middle section is connected with the steel-concrete section through the closure section steel box girder and then connected with the cast-in-place concrete beam section on the other side, temporary supports are arranged in emergency lanes of the expressway respectively, and the steel box girder middle section is integrally hoisted on the outer side of the expressway through a large crawler crane after being assembled outside the expressway. Each steel box girder middle section blocks the road only when the steel box girder middle section crosses the expressway, and expressway passing is not affected at other time. The method has the advantages that the construction time is short, the construction quality is guaranteed, and the influence on the traffic of the expressway is small, and can be widely applied to the construction of the overpass bridge of the expressway.
本发明提供了一种跨线钢桥快速施工结构及施工方法，通过采用钢混组合体系，跨线桥根据来往车道分成前幅跨线钢桥和后幅跨线钢桥，高速公路正上方采用钢箱梁中间段穿越，钢箱梁一侧通过钢混结合段与一侧现浇混凝土梁段连接，钢箱梁中间段另一侧通过合龙段钢箱梁与钢混段连接后再与另一侧现浇混凝土梁段连接，在高速公路的应急车道内分别设置临时支架，钢箱梁中间段在场外拼装完成后，通过大型履带吊在高速公路外侧整体吊装，为确保交通安全，每幅钢箱梁中间段仅在钢箱梁中间段跨越高速公路时封闭道路，其它时间高速公路通行不受影响。本发明具有施工时间快，施工质量有保证，对高速道路交通影响很小的优势，可广泛应用于高速公路跨线桥施工中。
