For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Example 1: A two-component grouting system, such as Figure 1-3As shown, it includes a component A storage tank 1, a component B storage tank 2, and a diluent storage tank 3. The component A storage tank 1 is equipped with a stirrer, which includes a motor 4, a stirring shaft 5, and stirring blades 6. The stirring blades 6 include blades I7 that are evenly arranged around the circumference of the stirring shaft 5. The blades I7 rotate synchronously under the drive of the motor 4 and the stirring shaft 5, thereby stirring the material in the component A storage tank 1. The blade I7 has a hollow structure that is connected to the stirring shaft 5. The blade I7 is evenly provided with liquid outlet holes 8. The stirring shaft 5 has a hollow structure, and its top is evenly provided with feed holes 9 and its bottom is evenly provided with discharge holes 10, which facilitates the dispersion of viscous grouting materials. The A component storage tank 1 is provided with blade II 11 symmetrically arranged above the stirring shaft 5. Blade II 11 is fixedly connected to the stirring shaft 5. Blade II 11 is "┑" shaped and matches the inner side wall of the A component storage tank 1. Blade II 11 is provided with scraper 12. Blade II 11 can effectively stir the material near the side wall of the A component storage tank 1. At the same time, scraper 12 can scrape off the material adhering to the inner wall of the A component storage tank 1. A cylindrical shell 13 is installed on the top of the A component storage tank 1. The cylindrical shell 13 is located on the top periphery of the stirring shaft 5. The inlet of the cylindrical shell 13 is connected to the outlet of the diluent storage tank 3. The diluent enters through the inlet of the cylindrical shell 13, enters the hollow structure through the inlet hole 9 at the top of the stirring shaft 5, and enters the A component storage tank 1 through the outlet hole 10 and the liquid outlet hole 8 on the blade I7, thereby diluting the A component of the grouting material. The outlets of both the A component storage tank 1 and the B component storage tank 2 are connected by pumps. The mixing tank 14 is connected to the inlet of the mixing tank 14. The mixing tank 14 is equipped with a stirring device 20. The shell of the mixing tank 14 is provided with an insulation jacket 15, which contains a heating wire 16 and a heat-conducting oil 17. The stirring device 20 stirs the mixture, and the heating wire 16 and heat-conducting oil 17 in the insulation jacket 15 heat the mixture, ensuring uniform mixing of components A and B. For materials requiring heating to react, the reaction can occur during heating. The resulting slurry is then injected into the grouting system. The outlet of the mixing tank 14 is connected to the inlet 19 of a piston-type grouting device 18. One end of the piston-type grouting device 18 has an outlet 21, and the other end has a water inlet 22. The water inlet 22 is connected to a water inlet pipe 23, which is connected to a water storage tank 24 via a water pump. The outlet 21 is connected to a grouting pipe 25, which is connected to the grouting port via a grouting pump 26. The piston-type grout injector 18 has a sealing plug 27 inside, and a scale 28 is provided on the outside of the piston-type grout injector 18. The starting position of the scale is at the grout outlet end of the piston-type grout injector 18.After mixing, the slurry enters the piston-type grouter 18 through the slurry inlet 19. Water enters the lower side of the sealing plug 27 through the water inlet pipe and water inlet 22. The water pressure pushes the sealing plug 27 upward, thereby pushing the grouting liquid through the slurry outlet 21 and the grouting pump 26 into the grouting pipe 25 and the grouting port, thereby performing grouting repair treatment on the area that needs grouting. It is highly practical.

[0018] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
