Of course, in other examples, the first pipe joint 21 and the grouting member 3 are not limited to the spring 7, but components with certain deformability such as rubber, silica gel, resin and the like can be selected, so that the components arranged between the pipe joint 2 and the grouting member 3 can be elastically deformed at normal temperature, can be greatly deformed under a small force, and can be restored to the original state after the external force is removed, thereby driving the grouting plate 32 to move towards the direction of the construction surface so as to maintain the pressure of the grouting plate 32 on the construction surface.

In some embodiments of the present application, as shown in fig. 4, the steering structure 221 is spherically provided on the pipe joint 2, and the pipe joint 2 and the grouting 3 are spherically hinged by the steering structure 221. The relative rotation of the grouting piece 3 and the pipe joint 2 is realized through the spherical steering structure 221, so that the pipe joint 2 and the storage barrel 1 can automatically adjust the self inclination angle according to the positions of holes with different heights, the grouting piece 3 can automatically adjust the self inclination angle according to the construction surfaces with different inclination angles, and even if the central axis of the storage barrel 1 and the central line of the holes are not on the same horizontal plane, the grouting piece 3 can be completely clung to the construction surfaces, and the hole plugging quality is improved.

In specific examples, as shown in fig. 4, the steering structure 221 is spherically provided on the second pipe joint 22, and the connection cylinder 31 is connected to the second pipe joint 22 through the steering structure 221. The connecting cylinder 31 can rotate for a certain angle relative to the second pipe joint 22, so that the grouting plate 32 is driven to rotate, the grouting plate 32 can be always attached to a construction surface in the process of plugging holes by the hole plugging device 100, and grouting quality is improved.
