The arch-first beam-second beam type is a common construction method of an arch bridge, in the construction of a general large-scale arch bridge, after a main arch is finished and a beam system is erected, partial heavy materials need to be transferred to a river channel area, certain arch bridges are located on a main channel, the material transfer by a ship for long-time sealing is impossible, and the material transfer generally needs a cableway device. Heavy-duty tower ropeways and light-duty circulating wire rope ropeways are two main implementations of such devices. The heavy-duty cable tower cableway needs to erect special temporary steel cable towers with high rise on two sides of an arch bridge, and the heavy-duty bearing steel wire rope cableway is erected on the top of the cable tower, so that the heavy-duty cable tower cableway has the advantages of high construction standardization degree, large bearing capacity and the like. However, for some arch bridges, the arch ribs are spliced on the support in the river, a river channel area does not have a large amount of heavy material transfer requirements, the arrangement is convenient, and the light cableway transfer device based on the circulating steel wire rope catenary structure with low cost can be transported as required. In recent years, light circulating wire rope ropeways are widely applied to the construction of large arch bridges.
The main types of heavy ropeway currently in use are: the cable comprises a steel tower cable way consisting of a high-rise steel cable tower, a large-diameter steel wire rope cable way, a displacement hoisting mechanism and the like, or a mountain anchor room cable way consisting of a mountain anchor room on the shore side, a large-diameter steel wire rope and a displacement hoisting mechanism. However, in the actual construction process, such heavy ropeways have the disadvantages of more auxiliary mechanisms, complex equipment layout, huge large-tonnage steel wire rope tightening mechanisms, large change of the ropeway sag during heavy load, high installation and disassembly cost and the like.
At present, a large arch bridge is built on a navigation channel at a sea exit in a coastal plain area, the distance between a bridge floor and the water surface of a navigation area is very small, and all construction measures need to be operated above a bridge bottom elevation line. In response to this special requirement, a cableway transfer device based on a circular steel wire rope catenary structure needs to be developed, and construction materials are borne and transported by cableway steel wire ropes. Its advantage does: only need seal a voyage for a short time and erect the cableway, subsequent work all can be higher than the bridge floor operation, has reduced the navigation way management and control risk, has solved the contradiction of construction and seal a voyage. It also has the advantages of convenient installation and disassembly, convenient use and low cost.
