[0002] Road bridges are generally composed of several parts, including roadbed, pavement, bridges, tunnel projects and traffic engineering facilities. With the rapid development of my country in recent years and the huge investment in infrastructure, my country's railways and highways have developed rapidly, and bridge structures such as viaducts have also become the main road mode. After long-term use, various cracks will appear on the surface of the bridge. These cracks are likely to affect the safety of vehicles. In addition, there is a risk that the cracks will further expand and even cause partial fractures in the bridge. Therefore, timely repairs are needed.

[0003] Patent CN221663362U discloses a crack repair device for roads, bridges and tunnels. During the repair work, the device uses a discharge nozzle to inject repair material into the crack.
