Abstract

The invention relates to a concrete-filled steel tube arch bridge construction support system which comprises assembly type step anchor cable frame anchoring bottom beams, abutment pier bearing platforms, abutment pier bodies, a main pier bearing platform, flexible carrying nets, bags, counterforce prepressing anchor cables, a quick-installing quick-detaching construction support system attached to a constructed structure and a prestressed steel tube beiley beam portal system. The assembly type step anchor cable frame anchoring bottom beams are pre-buried in a soil layer and provided with anchor cable pre-buried sections used for fixing the counterforce prepressing anchor cables. The bags are arranged above the flexible carrying nets, the flexible carrying nets are provided with side end plates, and the upper portion of each flexible carrying net is divided into multiple cavities through easily-detached cavity division plates. The system has the beneficial effects that a construction method of combination of assembly type step anchor cable frame anchoring bottom beam counterforce prepressing and bag water injection weight prepressing is provided, an unnecessary construction procedure is reduced, the construction period is shortened, the construction cost of a construction organization is reduced, the engineering quality is improved, and cost can be effectively saved.

Description

technical field [0001] The invention relates to a construction support system and a construction method of a steel tube concrete arch bridge, which belongs to the field of civil engineering and is suitable for support construction of a steel tube concrete arch bridge. Background technique [0002] The arch bridge has a long history and it is one of the oldest basic bridge types. It has the advantages of beautiful appearance, light structure and large span. Due to the existence of horizontal thrust, the bending moment in the arch is greatly reduced under the action of vertical load. It is a structural system that mainly bears pressure, especially when the arch axis is reasonable, it can give full play to the characteristics of the material. However, under the development trend of modern bridges with large spans, arch bridges have also shown many shortcomings, such as the impact of large spans on their own stability, and the inconvenience of construction caused by large self-...
