Construction method for steel-concrete mixed section of cable-stayed bridge
The invention provides a construction method for a steel-concrete mixed section of a cable-stayed bridge, which is characterized by comprising the following steps of: pre-burying a thick steel plate for later welding of a stiff skeleton during construction of a mid-span No.15 beam section, meanwhile, modifying a cantilever bridge fabrication machine into a deck crane, moving the deck crane forwards and anchoring, and entering a steel-concrete combined area steel box beam hoisting state; the steel-concrete combined section I enters a preset position, a bridge deck crane vertical lifting system is used for lifting the steel beam to a design position, a No.15 beam section and the steel-concrete combined section I are fixed, middle span No.16-No.1 beam section concrete is poured, and side span No.16-1'and No.16-2 'beam sections are constructed; connection between the deck crane and the concrete combination section I is removed, middle span 16-2 beam section concrete is poured, a side span cast-in-place section 18 'beam section support is erected, a beam end permanent support is installed, and side span cast-in-place section concrete is poured. The problems that in the prior art, the construction period is long, and the input cost is high can be solved.
本发明提供一种斜拉桥钢‑混凝土混合段施工方法，其特征在于，包括如下步骤：在中跨15号梁段施工时预埋厚钢板，用于后期焊接劲性骨架，同时将悬臂造桥机改装成桥面吊机，将桥面吊机前移并锚固，进入钢混结合区钢箱梁吊装状态；使钢混结合段Ⅰ进入预定位置，利用桥面吊机竖向提升系统将钢梁提升至设计位置、固定15号梁段与钢混结合段Ⅰ，浇筑中跨16‑1号梁段混凝土，施工边跨16‑1ˊ号、16‑2ˊ号梁段；解除桥面吊机与混结合段Ⅰ连接、浇筑中跨16‑2号梁段混凝土、搭设边跨现浇段18ˊ号梁段支架、安装梁端永久支座、浇筑边跨现浇段混凝土。本发明可以解决现有技术中施工周期长，投入成本大存在的问题。
