Lower Part the Bridge Reinforces the Design and the Construction

The fiber cloth takes one kind of new structure reinforcement material, has the light quality excel, the high elasticity module, anti-corrosive, the anti-impact, anti-to cut, the fatigue resistance to be able and characteristics and so on good ductility. This article introduced reinforces some bridge＇s mechanism with the textile fiber cloth, the reinforcement designs and constructs the craft.
