[0023] See also Figure 1-5 As shown, a grouting plug comprises a grouting pipe 1. The top of the inner cavity of the grouting pipe 1 is provided with a thread that can be connected with the grouting pipe thread, so as to facilitate the grouting of the grouting plug. The grouting pipe 1 can guide the concrete, so as to facilitate the subsequent grouting. One side of the grouting pipe 1 is fixedly connected with a mounting pipe 2. One side of the inner cavity of the mounting pipe 2 is provided with an extrusion mechanism 3. One side of the extrusion mechanism 3 is provided with a first airbag 4. One side of the first airbag 4 is fixedly connected with the inner wall of one side of the mounting pipe 2. The inner cavity of one side of the mounting pipe 2 is designed as a cylinder. The surface of the first airbag 4 is slidably connected with the inner wall of the mounting pipe 2. Under this action, the first airbag 4 can be made more stable when squeezed. Two places on one side of the first airbag 4 are connected with connecting pipes 5. The other end of the connecting pipe 5 penetrates into the interior of the grouting pipe 1. A rubber shell 6 is installed on the surface of the grouting pipe 1. The inner cavity of the rubber shell 6 is installed with a second airbag 7. The second airbag 7 and the connecting pipe 5 are connected to each other. Under this action, the squeezing mechanism 3 can squeeze the first airbag 4, so that the first airbag 4 can discharge the internal air into the interior of the second airbag 7 through the connecting pipe 5. With the cooperation of the second airbag 7, the rubber shell 6 is expanded to make the first airbag 4 The grouting plug can be stuck on the inner wall of the pipe. The surface of the grouting pipe 1 is provided with a mounting groove 8. There are four mounting grooves 8, which are distributed in a circular array at the center of the grouting pipe 1. A cleaning mechanism 9 is installed inside the mounting groove 8. The cleaning mechanism 9 can clean the inner wall of the pipe to reduce foreign matter inside the pipe and reduce the situation where the rubber shell 6 slips and detaches from the inside of the pipe after being stretched open, which effectively improves the stability of the grouting plug when in use. A scraper 10 is fixedly connected to the surface of the grouting pipe 1. The scraper 10 is designed with a rubber material, and the diameter of the scraper 10 is larger than the diameter of the rubber shell 6. Diameter, under this action, when the grouting plug is inserted into the interior of the pipe, the scraper 10 can scrape the inner wall of the pipe to clean the sewage and other foreign matter on the inner wall of the pipe. A pushing shell 11 is fixedly connected below the surface of the grouting pipe 1. The pushing shell 11 is designed as a conical structure. The diameter of the pushing shell 11 is the same as the diameter of the rubber shell 6. Under this action, after the grouting plug is inserted into the inner wall of the pipe, the pushing shell 11 can scrape off larger foreign matter such as soil inside the pipe, thereby reducing larger foreign matter such as soil on the inner wall of the pipe, which is convenient for the subsequent cleaning mechanism 9 and the scraper 10 to clean the pipe.

[0024] The cam 32 is a substantially rectangular shape, and one side of the inner cavity of the mounting tube 2 is substantially rectangular. The surface of the cam 32 is slidably connected to the inner wall of the mounting tube 2, so that the cam 32 can be guided when moving, so that the cam 32 can be more stable when moving. A connecting rod 33 is fixedly connected to one side of the cam 32, and an extrusion plate 34 is fixedly connected to one end of the connecting rod 33. The extrusion plate 34 is used in conjunction with the first airbag 4. Under this action, it is convenient for the staff to squeeze the first airbag 4, so as to facilitate the fixing of the grouting plug to the inner wall of the pipe. A connecting block 12 is fixedly connected to one end of the threaded rod 31. The connecting block 12 is a regular hexagonal design. The connecting block 12 can facilitate the staff to use auxiliary tools to drive the threaded rod 31 to rotate, so as to facilitate the staff to fix the grouting plug.

[0025] The cleaning mechanism 9 includes a compression spring 91, one end of the compression spring 91 is fixedly connected to the inner wall of the mounting groove 8, and the other end of the compression spring 91 is fixedly connected to a movable rod 92. The movable rod 92 is designed as a T-shaped structure. The surface of the movable rod 92 is slidably connected to the inner wall of the mounting groove 8. One end of the movable rod 92 is fixedly connected to a cleaning brush 93. The cleaning brush 93 is designed as an arc. Under this action, when the grouting plug moves inside the pipe, the cleaning brush 93 can clean the inside of the pipe, and under the action of the compression spring 91, pressure can be applied to the cleaning brush 93 to enhance the cleaning effect of the cleaning brush 93.

[0026] It is worth noting that the technical features such as the grouting pipe 1 proposed in this technical solution should be regarded as the prior art. The specific structure, working principle and possible control method and spatial arrangement method of these technical features can be selected according to the conventional methods in the field, and this technical solution will not be further elaborated.

[0027] Working principle: first, connect the top of the grouting pipe 1 with the grouting pipe, then insert the grouting pipe 1 into the interior of the pipe, and then when the grouting pipe 1 moves, the larger foreign matter on the inner wall of the pipe will be cleaned by pushing the shell 11, and the foreign matter inside the pipe can be cleaned with the cooperation of the compression spring 91 and the cleaning brush 93, and finally, with the cooperation of the scraper 10, the foreign matter and sewage inside the pipe can be cleaned, so as to facilitate the subsequent installation of the grouting plug, and then move the grouting pipe 1 to a suitable position, and then the staff rotates the connecting block 12, and under the action of the connecting block 12, the threaded rod 31 can be rotated to move the sleeve 32 and the extrusion plate 34 can be squeezed through the connecting rod 33 to squeeze the first airbag 4, and the air inside it is discharged into the interior of the second airbag 7 through the connecting pipe 5, so that the rubber shell 6 can be deformed, and under the action of the rubber shell 6, the grouting plug can be stuck in the interior of the pipe, and then grouting can be started.
