Tunnel lining defect reinforcing equipment and reinforcing method thereof

The invention relates to the field of tunnel construction, in particular to tunnel lining defect reinforcing equipment which comprises a movable vehicle body arranged in a construction tunnel. And a lifting plate is arranged above the movable vehicle body. According to the tunnel lining defect reinforcing equipment, in the construction process of reinforcing a second lining of a tunnel by pasting the steel belt on the cambered surface, through mutual cooperation of the coating assembly, the knocking assembly and the connecting assembly, glue can be automatically smeared on the steel belt on the arc-shaped mounting plate, and in the smearing process, the glue can be automatically smeared along with movement of the arc-shaped mounting plate; according to the device, colloid smearing operation can be conducted on the steel belt more efficiently and evenly, vibration can be generated in the process that the steel belt abuts against the tunnel wall through the abutting and knocking effect on the arc-shaped mountin
