Abstract

The invention discloses a steel arch frame assembling and transverse moving system and method for an upper bearing type arch bridge construction. The system comprises an arch frame assembling device for assembling a steel arch frame and an arch frame supporting and transverse moving device for supporting and transversely moving the assembled steel arch frame. The method comprises the following steps that 1, a bridge lower supporting structure and steel arch frame support are constructed, and a horizontal moving slide way and a lifting device are installed; 2, a cable crane and the arch frame are transferred to the device in section for construction; 3, the steel arch frame is assembled; 4, an arch supporting frame is jacked; 5, the arch supporting frame is lowered; 6, a transverse moving driving device is installed; 7, the arch supporting frame is transversely moved; and 8, the arch supporting frame is jacked. The steel arch frame assembling and transverse moving system and method forthe upper bearing type arch bridge construction are reasonable in design, convenience and simple are realized, the use effect is good; the arch frame assembling device and the arch frame supporting and transverse moving device are matched and used, the steel arch frame assembling process can be completed simply and quickly, the steel arch frame can be transversely moved through the arch support and the transverse moving device, and the purpose of constructing the two arch ribs through the steel arch frame is achieved.

Description

technical field [0001] The invention belongs to the technical field of bridge construction, and in particular relates to a system and method for assembling and laterally moving a steel arch frame for the construction of an upwardly supported arch bridge. Background technique [0002] The overhanging arch bridge is a bridge whose deck is set on the main load-bearing structure of the bridge span (that is, the arch rib). At the junction of the bedrock, both ends of the arch ribs of the upward arch bridge are supported on the abutment, which is an important component supporting the structure on the arch. The abutment used to support the arch rib is a permanent support, which is generally a reinforced concrete structure supported on the bedrock. Among them, the arch rib is also called the main arch or the arch ring. For the construction of the box-type box arch bridge whose arch rib is reinforced concrete arch ring, the arch rib usually adopts the pre-erected steel arch frame fo...
