The knocking ball 13 is driven by the second hydraulic cylinder 7 to repeatedly knock on the wall. By listening to the sound, it can be determined whether a hollow is present. If a hollow is present, the device is rotated in direction, and the height of the drilling mechanism is adjusted to meet the height to be repaired by adjusting the first hydraulic cylinder 39 and the first piston rod 37. The drilling mechanism is flipped over by the clamping block 3 so that the drill rod 23 faces the wall and is tilted to contact the hollow position. The motor 16 drives the driving wheel 19 to rotate, and the engagement of the driving wheel 19 and the driven wheel 21 drives the drill rod 23 to rotate, and the drill rod 23 is used to drill a hole in the hollow position, and then the feeding tray 25 is covered at the drilling position. Since there is a feeding pipe 27 between the material pump 29 and the movable support box 36, when the switch of the material pump 29 is turned on, the material in the movable support box 36 will be filled into the hollow position of the wall along the feeding tray 25, and finally the knocking ball 13 is used to knock, and the filled material is vibrated to compact it, thereby achieving non-destructive repair of the hollow wall.
