Construction method of large-span basket type steel box arch
The invention relates to a construction method of a large-span basket type steel box arch, and relates to the technical field of construction. Comprising the steps that a concrete beam body is constructed through a hanging basket method; an arch support concrete section is constructed, and then the end assembling supports, the middle assembling supports, the S0-S3 steel box arch sections and the S4-S10 steel box arch sections are hoisted; hoisting the lifting bracket; mounting a middle assembly bracket, the steel box arch sections from S4 to-10, a lifting bracket and the steel box arch sections from S0 to S3 at the other end in sequence; longitudinal steel strands, transverse finish rolling deformed steel bars and transverse opposite-pulling trusses of the steel box arch sections from S4 to-10 are installed; a lifting system of the S4 to-10 steel box arch sections is installed; hoisting a closure section; and mounting a suspender and integrally performing cable force adjustment. According to the invention, the material can be reused, so that the material waste is reduced, and the cost is saved; the coordinate position of the steel box arch is positioned more accurately, and adjustment is convenient and simple; construction safety is guaranteed, operation of workers is convenient, and space is large.
本发明关于一种大跨度提篮式钢箱拱的施工方法，涉及施工技术领域。包括：混凝土梁体采用挂篮法施工；施工拱座混凝土段，再吊装端部拼装支架和中部拼装支架以及S0‑S3钢箱拱节段和S4‑S10钢箱拱节段；吊装提升支架；依次安装中部拼装支架、S4至‑10钢箱拱节段、提升支架及另一端的S0至S3钢箱拱节段；安装S4至‑10钢箱拱节段的纵向钢绞线和横向精轧螺纹钢及横向对拉桁架；安装S4至‑10钢箱拱节段的提升系统；吊装合龙段；安装吊杆并整体进行索力调整。本发明材料可重复利用，减少了材料的浪费，节省了成本；更精准的定位了钢箱拱坐标位置，且调整方便简捷；保证了施工安全，工人操作方便，空间大。
