Background

In urban rail transit construction, a double-U-shaped bridge is used as a novel bridge structure and has the advantages of clear stress, light structure weight, attractive appearance, high space utilization rate and the like. Because the width of the U-shaped bridge is large, the double-U-shaped prefabricated section beam is often adopted for construction. In order to meet the hoisting requirement of the double-U-shaped prefabricated section beam, hoisting holes must be reserved on a bottom plate of the U-shaped prefabricated section beam in the beam body prefabricating process, and after the beam body is installed, the hoisting holes are blocked.

The traditional plugging method is that a bamboo plywood with the diameter slightly larger than that of a hoisting hole channel is suspended below the hole channel through a steel wire rope to serve as a template, and finally concrete is poured into the hole to complete plugging treatment. Firstly, although the method is simple and convenient, the process is rough, the plugging effect is poor, and the problem of long-term leakage of the hoisting pore canal cannot be solved; secondly, in order to remove the bamboo plywood formwork, high-altitude operation is often required, and construction risk is high; finally, because the concrete completely depends on the cohesive force with the inner wall of the steel pipe to overcome the influence of gravity, the double-U-shaped bridge can be influenced by the vibration of the train for a long time in the future operation process, and the blocking concrete can be loosened or even fall off, so that potential safety hazards such as high-altitude falling exist.
