[0028] Specifically, the rotating disc is connected with the work bin through the limiting ring, the end surface of the rotating disc towards the crack is provided with a concave cavity, three working cavities are arranged on the concave cavity, and the angle between adjacent working cavities is 120°, a plurality of grooves are arranged on the side wall of the concave cavity, the grooves are arranged to realize the pushing of the pusher at a greater distance, and then the drilling, cleaning, grouting and other steps of the deeper crack are realized. The drilling piece, the cleaning piece and the grouting piece are sequentially arranged in the working cavities. The part of the rotating disc near the through hole is provided with external teeth, and the external teeth are engaged with the main gear. The main gear is provided with a driving motor. The driving motor starts the main gear to drive the rotating disc to rotate. Every 120° rotation realizes the switching of the working cavities, and different operations are performed on the crack. Because the cracks are different, the steps are different, for example, some cracks do not need cleaning or drilling steps, and direct grouting; therefore, the situation of the crack needs to be analyzed or understood in advance before repairing the crack.

[0029] As shown in the figure, Figures 4-7 The drilling piece, the cleaning piece and the grouting piece are connected with the working cavities in an extension and retraction mode. The drilling piece is taken as an example for illustration. A guide cavity is arranged in the working cavity. The drilling piece includes a mobile base. A guide block is arranged on the outer wall of the mobile base corresponding to the guide cavity. An extension spring is arranged between the guide block and the guide cavity. One end of the extension spring is fixed to one end of the guide block, and the other end is fixed to one end of the guide cavity near the crack.
