Construction method of steel-concrete mixed combined continuous rigid frame bridge
The invention discloses a construction method of a steel-concrete mixed combined continuous rigid frame bridge, which comprises the following steps: S1, pouring of a cantilever pouring section: pouring a cantilever pouring section by using a rhombic hanging basket through a hanging basket method; S2, hoisting of a steel-concrete combined section: modifying the rhombic hanging basket on the cantilever pouring section to form a first hoisting device; enabling the first hanging system to be connected with a lifting lug on the steel-concrete combined section through a sling so as to lift the steel-concrete combined section; S3, installing steel-concrete combined sections, and carrying out cast-in-place joint pouring between the cantilever pouring section and the steel-concrete combined section; S4, hoisting a midspan steel box girder, enabling the first hoisting device to move to a position meeting the hoisting condition through a deformation anchoring system, modifying the first hoisting device, and forming a second hoisting device; enabling the two second hoisting devices on the adjacent bridge piers to hoist the two ends of the midspan steel box girder at the same time; and S5, installing a midspan steel box girder, and enabling the steel-concrete combined section and the end of the midspan steel box girder to be welded and fixed.
本发明公开了一种钢‑混凝土混合组合连续刚构桥梁的施工方法，包括如下步骤：S1：悬臂浇筑段的浇筑，利用菱形挂篮采用挂篮法浇筑悬臂浇筑段；S2：钢混结合段的起吊，对悬臂浇筑段上的菱形挂篮进行改制，形成第一起吊装置；所述第一吊挂系统通过吊索连接钢混结合段上的吊耳，从而起吊所述钢混结合段；S3：钢混结合段的安装，在悬臂浇筑段与钢混结合段之间进行现浇接缝浇筑；S4：跨中钢箱梁的起吊，所述第一起吊装置利用走形锚固系统移动至满足起吊条件的位置，对第一起吊装置进行改制，形成第二起吊装置；相邻桥墩上的两个第二起吊装置同时起吊跨中钢箱梁的两端；S5：跨中钢箱梁的安装，将钢混结合段和跨中钢箱梁的端部进行焊接固定。
