Method for constructing large-span cast-in-place reinforced concrete arch ring through cable-stayed hanging basket
The invention relates to the field of bridge engineering, in particular to a method for constructing a large-span cast-in-place reinforced concrete arch ring through a guyed hanging basket. A cable crane is installed, and 0 # section arch ring concrete is cast in situ through a support method; mounting a cable-stayed hanging basket, and tensioning a buckle cable and an anchor cable to enable the cable-stayed hanging basket to be located at a designed position; cast-in-situ arch ring sections are arranged on the cable-stayed hanging basket; after the concrete of the arch ring sections reaches the design strength, the buckling cables are converted to the reinforced concrete arch ring sections from the cable pulling hanging baskets; the guy cable hanging basket moves forwards by one section; tensioning the buckle cable and the anchor cable to enable the guy cable hanging basket to be located at a designed position; cast-in-situ arch ring sections are arranged on the cable-stayed hanging basket; and the steps are repeated until the arch ring closure section is constructed. The method for constructing the large-span cast-in-place reinforced concrete arch ring through the guyed hanging basket has the advantages of being high in work efficiency, low in safety risk, low in cost, convenient to construct and operate, capable of reducing construction risks and the like, and has good economic benefits and social benefits.
本发明涉及桥梁工程领域，尤其是涉及一种采用牵索挂篮施工大跨度现浇钢筋混凝土拱圈方法，施工方法共分为：拱座施工；安装缆索吊机，支架法现浇0#段拱圈混凝土；安装牵索挂篮，张拉扣索和锚索使牵索挂篮位于设计位置；在牵索挂篮上现浇拱圈节段；拱圈节段混凝土达到设计强度后，将扣索由牵索挂篮转换到钢筋混凝土拱圈节段上；牵索挂篮前移一个节段；张拉扣索和锚索使牵索挂篮位于设计位置；在牵索挂篮上现浇拱圈节段；重复以上步骤直至施工拱圈合龙段。该采用牵索挂篮施工大跨度现浇钢筋混凝土拱圈方法具有工效高、安全风险低、成本低、施工方便，便于操作，从而能够降低施工风险等优点，具有较好的经济效益和社会效益。
