| Abstract: | Steel pipe arch bridge is a common type of highway bridge, but arch rib concrete is a common disease of this kind of bridge. Aiming at this problem, this paper takes the excellent performance of high strength, low viscosity, high permeability, low temperature resistance and high flexibility grouting material in the simulation test as an example to illustrate the advantages of this material in the treatment of the arch rib of the steel pipe arch bridge. The research results of this experiment have practical application significance to the treatment of arch rib concrete caving disease. |
