Abstract: The skeleton of concrete filled steel tube arch bridge is made at the first step, then liftsegmented frame until the closure of arching, finally,the stiff skeleton as scaffold bear construction weight of internal pouring concrete and outsourcing concrete, and the outsourcing concrete as a partof the stress of main arch. Taking the glass ditch bridge as an object, this paper introduces the manufacture, assembly, construction and control of concrete filled steel tubular arch rib.
