Bridge reinforcing method and device

The invention discloses a bridge reinforcing method. The bridge reinforcing method comprises the following steps of construction preparation, pretreatment, base gel applying, carbon fiber cloth pasting, carbon fiber cloth reinforcing, and carbon fiber cloth surface treatment and detection. The cementation base gel comprises a main agent and a hardening agent, and the wight ratio is 2:1. The widthof the applied lines of the cementation base gel is 600mm, and line interval is 400mm, and therefore carbon fiber materials have high tensile strength and high anti-fatigue performance, are suitable for beam, plate and column reinforcement. Carbon fiber cloth reinforcing enables crack width to be controlled at a certain degree, and therefore width and space of the cracks are obviously decreased, the cracks are thinner, denser and shorter, so that corrosion resistance and loading capacity of concrete are improved, professional design service monitoring and safety operation management performance are further improved. 本
