[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0017] Example: Figure 1-3 As shown, the utility model provides an extra-long concrete wall crack control structure, wherein an injection tube 1 serves as a core component, and a fixing mechanism 2 is provided on its outer surface for firmly fixing the overall structure in the concrete wall. One end of the injection tube 1 is fixedly connected to a connecting mechanism 3 so as to be connected to grouting equipment or other related components. The fixing mechanism 2 specifically includes an expansion ring 20 and an expansion cylinder 21. The expansion ring 20 is tightly attached to the outer surface of the injection tube 1, and the expansion cylinder 21 is fixedly connected to one side of the expansion ring 20. In addition, a movable thread 22 is further provided on the outer surface of the injection tube 1, and a movable cylinder 23 is connected thereto by a thread. The push port 25 at one end of the movable cylinder 23 slides with the inner surface of the expansion cylinder 21 to realize the expansion and fixation of the fixing mechanism 2.
[0018] The snap-fit connection design between the injection port 28 and the injection tube 1 makes the injection of grouting material more convenient, and also facilitates the replacement and maintenance of the injection port 28. The equally spaced anti-slip grooves 27 enhance the friction between the expansion cylinder 21 and the concrete wall, thereby improving the stability of the fixing mechanism 2. The rotating grooves 24 on the outer surface of the movable cylinder 23 allow the staff to rotate the movable cylinder 23 more easily, thereby adjusting the expansion degree of the fixing mechanism 2 to achieve a more precise fixing effect.
[0019] The connecting mechanism 3 includes a connecting plate 30, which is fixedly connected to one end of the injection tube 1 away from the fixing mechanism 2. An extrusion ring 31 is fixedly arranged on the other side of the connecting plate 30. The outer surface of the extrusion ring 31 not only has an extrusion groove 32, but also has an extrusion thread 38. The extrusion cylinder 36 is connected to it through a thread. The grouting pipe 35 is arranged on the inner side of the extrusion cylinder 36, and the grouting port 33 at one end thereof cooperates with the extrusion ring 31 to inject the grouting material into the wall cracks in combination with the injection tube 1.
[0020] The expansion cylinder 21 and the extrusion ring 31 are made of a material with plasticity, which enables them to be better extruded, expanded and deformed, thereby improving the stability and effectiveness of the fixed connection. The coordinated use of the inclined groove 34 and the extrusion ring 31 enables the grouting pipe 35 to maintain a stable position during the grouting process, thereby avoiding the deviation of the grouting port 33 and the leakage of the grouting material. The waterproof rubber ring 37 design on the outer surface of the grouting pipe 35 effectively prevents the leakage of the grouting material during the grouting process, thereby improving the grouting effect and the durability of the wall.
[0021] Working principle: When the control structure needs to be fixed, the injection tube 1 is inserted into the reserved hole next to the crack in the concrete wall. By rotating the movable cylinder 23 on the fixing mechanism 2, the threaded connection between the movable thread 22 and the injection tube 1 is utilized to push the push port 25 toward the inside of the expansion cylinder 21. As the push port 25 goes deeper, the expansion cylinder 21 is squeezed and expands. At the same time, the design of the expansion groove 26 and the anti-slip groove 27 enables the expansion cylinder 21 to better fit the wall surface and generate sufficient friction, thereby achieving a firm fixing effect.
[0022] When grouting material needs to be injected into the cracks in the wall, the grouting pipe 35 and the extrusion cylinder 36 are first matched with the extrusion ring 31 through the connecting mechanism 3. Then, by rotating the extrusion cylinder 36 and utilizing the threaded connection relationship between the extrusion thread 38 and the extrusion ring 31, under the action of the inclined groove 34, the extrusion ring 31 is deformed and bent inward, so that it can limit the grouting port 33. At this time, the grouting material can enter the injection tube 1 through the grouting pipe 35 and the grouting port 33, and then be injected into the cracks in the wall to achieve repair and control of the cracks.
[0023] Obviously, those skilled in the art may make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if such modifications and variations fall within the scope of the claims of the present invention and their equivalents, the present invention is intended to include such modifications and variations.
