This causes the grout to flow and leak freely along the construction joints, resulting in grout waste, increased construction costs, and potential pollution of surrounding areas that do not require grouting. This also affects the overall aesthetics of the building structure and the normal progress of other construction procedures. Utility Model Content

[0029] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0030] Please refer to Figures 1-8 This utility model provides a waterproof grouting device for concrete construction joints, including a grouting tank 1, a grouting pipe 7 connected to the grout outlet of the grouting tank 1, a booster pump 6 and a press valve 8 installed on the grouting pipe 7, a grouting mechanism 2 connected to one end of the grouting pipe 7, the grouting mechanism 2 being movably installed in a fixed frame 9, and positioning mechanisms 3 being provided in the fixed frame 9 on both sides of the grouting mechanism 2.

[0031] Grouting tank 1 can be detachably installed on base frame 4, and casters 5 are fixedly installed at the bottom of base frame 4.

[0032] The base frame 4 and casters 5 make it easy to move the grouting tank 1, reducing the burden of manually moving the grouting device.

[0033] One end of the booster pump 6 is fixedly connected to the grout outlet of the grouting tank 1, and the other end is fixedly connected to the grouting pipe 7.

[0034] Grouting tank 1 is used to store grouting material. Booster pump 6 is connected between the grout outlet of grouting tank 1 and grouting pipe 7. Its function is to apply pressure to the grouting material so that it can be smoothly transported through grouting pipe 7. Press valve 8 allows operators to control the grouting process at any time and flexibly adjust the grouting volume and grouting time.

[0035] The fixed frame 9 has a movable groove 91 for limiting the movement of the slurry discharge mechanism 2 and the positioning mechanism 3.

[0036] The grouting mechanism 2 includes a grouting head 21. The upper end of the grouting head 21 is fixedly connected to the grouting pipe 7. The grouting head 21 is fixedly installed inside the first slider 22. The first slider 22 is slidably connected to the inner wall of the movable groove 91. A first threaded sleeve 24 is fixedly connected to the upper surface of the first slider 22. A first fastening nut 23 is threadedly connected to the first threaded sleeve 24. The lower surface of the first fastening nut 23 abuts against the surface of the fixed frame 9.

[0037] The grout outlet head 21 of the grout outlet mechanism 2 is connected to the grouting pipe 7 and is used to inject grouting material into the construction joint. The grout outlet head 21 is installed in the first slider 22, which can slide in the movable groove 91 of the fixed frame 9 to adjust the position of the grout outlet head 21. The first threaded sleeve 24 on the first slider 22 cooperates with the first fastening nut 23. When the first fastening nut 23 is tightened, its lower surface abuts against the surface of the fixed frame 9, fixing the first slider 22 in the current position. By setting the position-adjustable grout outlet head 21, it can adapt to construction joints of different widths and positions, improving the versatility of the device. By fixing the position of the grout outlet head 21 with the first fastening nut 23, the stability of the grouting process is ensured, making the grouting more accurate.

[0038] The positioning mechanism 3 includes a positioning rod 31, the bottom of which is inserted into the construction joint for positioning. The positioning rod 31 is fixedly installed in the second slider 33, which is slidably connected to the inner wall of the movable groove 91. The second slider 33 can also slide within the movable groove 91 to facilitate adjustment of the position of the positioning rod 31. A second threaded sleeve 36 is fixedly connected to the upper surface of the second slider 33, and a second fastening nut 35 is threaded onto the second threaded sleeve 36. The lower surface of the second fastening nut 35 abuts against the surface of the fixing frame 9. The second threaded sleeve 36 and the second fastening nut 35 cooperate, and tightening the second fastening nut 35 can fix the second slider 33. An airbag 32 is fitted with an air tube 321 fixedly connected to the upper end of the airbag 32. The air tube 321 passes through the second slider 33 and is fixedly connected to a pressing airbag 34 at its upper end. The airbag 32 is connected to the pressing airbag 34 through the air tube 321. When the pressing airbag 34 is pressed, air enters the airbag 32 through the air tube 321, causing it to expand. After the airbag 32 expands, it can not only further fix the position of the positioning rod 31 in the construction joint, but also form a barrier in the construction joint. During the grouting process, when the grout is injected into the construction joint from the grout outlet 21, the airbag 32 can intercept the grout, preventing the grout from flowing out along the construction joint at will, and confining the grout to a specific grouting area.

[0039] The airbag 32 increases the stability of positioning and prevents the device from shifting during grouting. On the other hand, its ability to trap grout greatly improves the accuracy of the grouting area, avoids grout waste and pollution of unnecessary surrounding areas, thereby improving the quality and effect of waterproof grouting.

[0040] In summary, the working principle of the concrete construction joint waterproofing grouting device according to this utility model embodiment is as follows:

[0041] When performing waterproof grouting at concrete construction joints, the device is first moved to the construction joint using casters 5. The positioning rod 31 of the positioning mechanism 3 is then inserted into the construction joint. Depending on the specific conditions of the construction joint, the position of the positioning rod 31 is adjusted by sliding the second slider 33 within the movable groove 91. The second fastening nut 35 is then tightened to secure it. Next, the airbag 34 is pressed to inflate the airbag bag 32, which stabilizes the positioning rod 31 and prepares for subsequent grout interception. Then, the booster pump 6 is started, and the press valve 8 is opened. The grouting material in the grouting tank 1 is transported to the grout outlet 21 through the grouting pipe 7 under the action of the booster pump 6 and injected into the construction joint. The position of the grout outlet is adjusted by sliding the first slider 22 within the movable groove 91. During the grouting process, the airbag bag 32 plays a role in intercepting the grout, confining it to the expected area and improving the accuracy of the grouting area.

[0042] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
