Method for constructing large-span cast-in-place reinforced concrete arch bridge through tower crane
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 bridge through a tower crane. The construction method comprises the following steps: constructing the skewback, and assembling the tower crane near the skewback; constructing a junction pier by using a tower crane, and mounting a hanging basket; a tower crane is used as hoisting equipment, and arch ring sections are constructed on the hanging basket; arch ring segments are constructed in a mid-span advancing mode through a buckling and hanging method; another tower crane and a component storage platform are assembled on the constructed arch ring section through the tower crane near the junction pier; a tower crane near the junction pier is used for firstly hoisting a component needing to be hoisted to the component storage platform, then the tower crane on the arch ring is used for hoisting the hoisted component to the hanging basket for construction of other arch ring sections, and the tower crane on the arch ring is used for arch ring closure. The construction method of the large-span cast-in-place reinforced concrete arch bridge has the advantages of being high in work efficiency, short in construction period, 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，尤其是涉及一种利用塔吊施工大跨度现浇钢筋混凝土拱桥方法。施工方法共分为：拱座施工，在拱座附近拼装塔吊；利用塔吊施工交界墩，并安装挂篮；利用塔吊作为吊装设备，在挂篮上施工拱圈节段；采用扣挂法向跨中推进施工拱圈节段；利用交界墩附近的塔吊在已施工完成的拱圈节段上拼装另外一台塔吊和构件存放平台；利用交界墩附近塔吊先将需要吊装的构件吊放至构件存放平台，再利用拱圈上的塔吊将吊装构件吊放至挂篮上进行其余拱圈节段施工，利用拱圈上的塔吊进行拱圈合龙。该大跨度现浇钢筋混凝土拱桥施工方法具有工效高、工期短、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。
