[0002] After the construction of a bridge, the bridge structure is prone to aging and failing to meet the operational strength requirements as it ages due to reasons such as inadequate tensioning during new construction. At this time, it is usually necessary to reinforce the bridge structure to reduce the occurrence of transverse cracks and cracks in the bridge. Carbon fiber cloth is required. Carbon fiber cloth products usually have good tensile strength. After tensioning the carbon fiber cloth, it is pasted to the bottom of the bridge, which can greatly improve the bridge's crack resistance and bending resistance.
