The pile foundation is usually erected in water, and the underwater structure of the bridge is prone to various damage defects due to high static stress and fatigue stress, continuous erosion, abrasion, cavitation, freeze-thaw and erosion in cold regions, ship collision, floating ice and earthquake attack, and usually needs to be repaired in time.

[0003] In the prior art, a basalt fiber repair and reinforcement system includes a basalt fiber ring arranged on the side of the pile foundation, a sealing ring arranged at the bottom of the basalt fiber ring, and a space for injecting concrete between the basalt fiber ring and the pile foundation.
