[0055] Example 2

[0056] This embodiment provides a working method of the curb slipform in-situ repair device described in Embodiment 1:

[0057] The repair personnel add the raw materials for preparing the repair concrete into the concrete bin in advance, and use the mixing mechanism to prepare the repair concrete.

[0058] The traveling vehicle moves to the position of the curb to be repaired, the mold cooperates with the curb, the traveling vehicle moves, and the first pump body, the second pump body, the third pump body and the conveying mechanism are turned on. When the traveling vehicle passes the damaged curb, it first sprays cleaning water on the surface of the damaged curb through the first nozzle to remove the loose parts and floating soil of the damaged curb, and then sprays the interface agent on the cleaned surface of the curb through the second nozzle. After the mold 4 passes the damaged curb, the damaged curb is poured with repair concrete to repair the damaged curb, and then the third nozzle sprays the curing agent on the repaired curb to cure the newly poured concrete. According to the actual working conditions, the traveling vehicle moves a set distance each time, the swing arm swings downward, and the repaired curb is slit by the slitting knife. During the slitting process, the traveling vehicle must stop. After the slitting is completed, the traveling vehicle continues to move.

[0061] Moreover, due to the spraying of the interface agent, the bonding strength between the newly poured concrete used for repair and the original concrete is guaranteed. The concrete can use the existing green high-performance concrete. The durability of the repaired curb is significantly enhanced, thereby greatly extending the service life of the curb.
