Abstract
Description
Technical Field
[0001] This utility model relates to the field of adaptive grouting technology, specifically to an adaptive grouting device. Background Technology
[0002] Adaptive grouting devices achieve dynamic responses to complex geological environments through integrated mechanical structures. With their high efficiency and flexibility, they have become key equipment in various engineering fields. In soft soil strata, the device can accurately locate cavities around shield tunnels and fill them with high-pressure grout to prevent ground subsidence. Addressing the risk of goaf collapse, the device can penetrate deep into roadways for dense grouting, forming a composite foundation. It can also penetrate micro-cracks through low-pressure, slow-injection methods, forming a seepage barrier in conjunction with fast-setting grout. Directional grouting reduces water waste, and grouting solidifies waste, preventing the leaching of harmful substances. Through the deep integration of mechanics, materials, and intelligent control, adaptive grouting devices not only solve the pain points of low efficiency, high cost, and significant safety risks in traditional grouting but also drive paradigm shifts in underground engineering, water conservancy projects, and environmental protection.
[0003] When dealing with high-concentration grouts, such as cement, water glass two-component grout, and ultrafine cement grout, existing grouting equipment is prone to local vortex phenomena when using traditional blade mixers. This can lead to material agglomeration, such as cement particles clumping together, resulting in a grout uniformity of less than 10%. Low grout uniformity directly affects grouting strength, causing insufficient mixing of high-viscosity grout, which in turn affects the overall grouting effect.
[0004] During the high-speed mixing process of mechanical blades, air is drawn in, resulting in a large number of air bubbles mixed in the grout. After grouting, the air bubbles in the grout will burst and form voids, which will seriously reduce the reinforcement effect. Honeycomb structures may be formed in the foundation grouting, which will greatly affect the stability of the foundation.
[0005] Different types of grout have different requirements for mixing conditions. Grout is quite sensitive to mixing speed. If the mixing speed is too fast, it is easy to cause premature solidification. For granular grout, such as sandy grout, if the mixing force is insufficient, it is easy to cause particle settling, which in turn will block the pipeline and affect the smooth progress of grouting operation.
[0006] The slurry storage tank also has the problem of dead corner residue, especially at the edges and bottom, where slurry is prone to remain and solidify. After long-term use, these solidified slurry residues will form hard lumps, which will not only wear down the agitator head, but may even jam the agitator rod, affecting the normal operation of the equipment.
[0007] During the mixing process, some grouting material can easily adhere to the inner wall of the mixing chamber. This not only reduces the mixing quality but may also contaminate the mixing of subsequent grouting materials. Furthermore, when the device is not in use, a large amount of residual grout inside the mixing tank cannot be cleaned properly, which will lead to a decrease in the adaptive adjustment accuracy of the subsequent device and affect the quality and efficiency of the grouting operation.
[0008] Therefore, there is an urgent need for an adaptive grouting device to solve the above problems. Utility Model Content
[0009] The purpose of this invention is to provide an adaptive grouting device to solve the problems mentioned in the background art, such as insufficient mixing of high-concentration grout, easy entrapment of air bubbles by mechanical mixing, dead corner residue in the grout storage tank and easy adhesion of grout to the inner wall, and incomplete cleaning of the device interior affecting the accuracy of subsequent adaptive adjustment.
[0010] To achieve the above objectives, the present invention provides the following technical solution: an adaptive grouting device, comprising a main body, and further comprising: a defoaming component disposed on the main body, used to enhance the stirring of the grout while simultaneously defoaming.

A stirring rod is fixedly connected to the bottom surface of the two second gears.

[0014] Preferably, a first connecting plate is fixedly connected to the top surface of the main body, a water pump is fixedly connected to the top surface of the first connecting plate, a first pipe is fixedly connected to the input end of the water pump, the first pipe passes through the first connecting plate, a water tank is fixedly connected to the bottom end of the first pipe, and the water tank is fixedly connected to the main body.
[0015] Preferably, the output end of the water pump is fixedly connected to a second pipe, the second pipe passes through the first connecting plate, and the output end of the second pipe extends to the upper part of the slurry storage tank.

[0017] Compared with the prior art, the beneficial effects of this utility model are:
[0018] This invention, through the coordinated stirring of the stirring head, defoaming plate, rotary scraper head, and scraper, effectively agitates the slurry, avoiding the localized vortices and material agglomeration problems common in traditional blade mixers. This improves slurry uniformity and ensures grouting strength. The defoaming groove on the defoaming plate effectively breaks up air bubbles in the slurry during stirring, reducing voids formed after grouting and enhancing reinforcement. It also prevents honeycomb structures and other problems during foundation grouting.

Sufficient stirring force also prevents particles in granular slurry from settling and clogging pipelines. The scraper prevents slurry from adhering to the inner wall of the storage tank. The rotation of the rotary scraper head, combined with water pump supply, thoroughly cleans the inside of the device, preventing slurry from solidifying and forming hard lumps that can jam the stirring head. This also prevents residual slurry from contaminating subsequent stirring and ensures the adaptive adjustment accuracy of the subsequent device. Attached Figure Description

[0027] 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.
[0028] Example 1: Please refer to Figures 1-7 The figure shows an adaptive grouting device, which includes a main body 1 and a defoaming component disposed on the main body 1, used to enhance the stirring of the grout while defoaming and quickly cleaning the grout storage tank.
[0029] The defoaming assembly includes a slurry storage tank 2, which is fixedly connected to the main body 1. Two support plates 19 are fixedly connected to the top surface of the slurry storage tank 2. A support frame 3 is fixedly connected to the top surface of the two support plates 19. An AC motor 4 is fixedly connected to the top surface of the support frame 3. A frequency converter 5 is installed on the AC motor 4. A rotating rod 6 is fixedly connected to the output end of the AC motor 4. A stirring head 7 is fixedly connected to the bottom end of the rotating rod 6. A scraper 18 is fixedly connected to the bottom end of the stirring head 7. A grouting pump 20 is fixedly connected to the bottom surface of the slurry storage tank 2.
[0030] When the grouting device is working, the grouting material is first fed into the grout storage tank 2 through the grout feeder 29. The AC motor 4 is started. Under the action of the frequency converter 5, the output speed of the AC motor 4 can be adjusted according to the type and characteristics of the grout. The AC motor 4 drives the rotating rod 6 to rotate. The stirring head 7 at the bottom of the rotating rod 6 rotates accordingly to stir the grout in the grout storage tank 2. At the same time, the scraper 18 at the bottom of the stirring head 7 will rotate against the inner wall of the grout storage tank 2 to prevent the grout from sticking to the inner wall at the bottom of the grout storage tank 2.
[0031] Please see Figure 5 The outer wall of the rotating rod 6 in the figure is fixedly connected to a first gear 8. Two second gears 9 are provided on the first gear 8. The two second gears 9 mesh with the first gear 8. The bottom surface of the two second gears 9 is fixedly connected to a stirring rod 10. The outer wall of the two stirring rods 10 is fixedly connected to a defoaming plate 11. Multiple defoaming grooves 12 are opened on the two defoaming plates 11.
[0032] When the rotating rod 6 rotates, the first gear 8 on its outer wall also rotates. Since the first gear 8 meshes with the two second gears 9, it will drive the two second gears 9 to rotate, which in turn will cause the two stirring rods 10 to rotate. The defoaming plate 11 on the outer wall of the stirring rod 10 rotates with the stirring rod 10, further stirring the slurry. The defoaming groove 12 on the defoaming plate 11 can break the air bubbles in the slurry during the stirring process, thus playing a defoaming role.
[0033] Please see Figure 6 The rotating rod 6 in the figure is fixedly connected to the outer wall of the rotating plate 14. The bottom surface of the rotating plate 14 is rotatably connected to two rotating shafts 15. The bottom surface of the two rotating shafts 15 is fixedly connected to a third gear 16. The inner wall of the slurry storage tank 2 is fixedly connected to a gear ring 13. The two third gears 16 mesh with the gear ring 13. The bottom ends of the two rotating shafts 15 are fixedly connected to rotating scraping heads 17. The two rotating scraping heads 17 are in contact with the inner wall of the slurry storage tank 2.
[0034] The rotating rod 6 drives the rotating plate 14 to rotate. The two rotating shafts 15 on the bottom surface of the rotating plate 14 rotate together with the rotating plate 14. Since the third gear 16 meshes with the gear ring 13, while the rotating shaft 15 revolves around the rotating rod 6, the third gear 16 will roll on the gear ring 13, causing the rotating shaft 15 to rotate, so that the rotating scraper head 17 at the bottom of the rotating shaft 15 rotates, which can stir the edge of the slurry tank 2.
[0035] Example 2: Please refer to 7. This embodiment further explains Example 1. The top surface of the main body 1 in the figure is fixedly connected to a first connecting plate 21. A water pump 23 is fixedly connected to the top surface of the first connecting plate 21. The input end of the water pump 23 is fixedly connected to a first pipe 24. The first pipe 24 passes through the first connecting plate 21. The bottom end of the first pipe 24 is fixedly connected to a water tank 22. The water tank 22 is fixedly connected to the main body 1. The output end of the water pump 23 is fixedly connected to a second pipe 25. The second pipe 25 passes through the first connecting plate 21. The output end of the second pipe 25 extends to the inside of the slurry storage tank 2.
[0036] A water inlet pipe 26 is fixedly connected to one side of the water tank 22. An adapter 27 is installed on the water inlet pipe 26. A second connecting plate 28 is fixedly connected to the top surface of the main body 1. A slurry feeder 29 is installed on the second connecting plate 28. A round hole 30 is opened on the main body 1.
[0037] When the cleaning device is needed, the water pump 23 is started. The water in the water tank 22 is pumped out by the water pump 23 through the first pipe 24 and transported to the slurry storage tank 2 through the second pipe 25. Then, the AC motor 4 is started to drive the rotating rod 6 to rotate. The rotation of the rotating rod 6 drives the rotating plate 14 to rotate. The two rotating shafts 15 on the bottom surface of the rotating plate 14 rotate together with the rotating plate 14. Since the third gear 16 meshes with the gear ring 13, while the rotating shaft 15 revolves around the rotating rod 6, the third gear 16 will roll on the gear ring 13, driving the rotating shaft 15 to rotate. This causes the rotating scraping head 17 at the bottom of the rotating shaft 15 to rotate, which can rotate and scrape the inner wall of the slurry storage tank 2.
[0038] The stirring head 7 at the bottom of the rotating rod 6 rotates accordingly, scraping the bottom surface of the slurry tank 2. It works in conjunction with the rotating scraping head 17 to complete the cleaning work. The water tank 22 can be filled with water through the water inlet pipe 26. The adapter 27 can be used to connect different types of pipes.
[0039] Working principle:
[0040] When the grouting device is working, the grouting material is first fed into the grout storage tank 2 through the grout feeder 29. The AC motor 4 is started. Under the action of the frequency converter 5, the output speed of the AC motor 4 can be adjusted according to the type and characteristics of the grout. The AC motor 4 drives the rotating rod 6 to rotate. The stirring head 7 at the bottom of the rotating rod 6 rotates accordingly to stir the grout in the grout storage tank 2. At the same time, the scraper 18 at the bottom of the stirring head 7 will rotate against the inner wall of the grout storage tank 2 to prevent the grout from sticking to the inner wall at the bottom of the grout storage tank 2.
[0041] When the rotating rod 6 rotates, the first gear 8 on its outer wall will also rotate. Since the first gear 8 meshes with the two second gears 9, it will drive the two second gears 9 to rotate, which in turn will cause the two stirring rods 10 to rotate. The defoaming plate 11 on the outer wall of the stirring rod 10 rotates with the stirring rod 10, further stirring the slurry. The defoaming groove 12 on the defoaming plate 11 can break the air bubbles in the slurry during the stirring process, thus playing a defoaming role.
[0042] The rotating rod 6 drives the rotating plate 14 to rotate, and the two rotating shafts 15 on the bottom surface of the rotating plate 14 rotate together with the rotating plate 14. Since the third gear 16 meshes with the gear ring 13, while the rotating shaft 15 revolves around the rotating rod 6, the third gear 16 will roll on the gear ring 13, causing the rotating shaft 15 to rotate, so that the rotating scraper head 17 at the bottom of the rotating shaft 15 rotates, which can stir the edge of the slurry tank 2. The grouting pump 20 is used to extract the evenly stirred slurry and carry out grouting operations.
[0043] When the cleaning device is needed, the water pump 23 is started. The water in the water tank 22 is pumped out by the water pump 23 through the first pipe 24 and transported to the slurry storage tank 2 through the second pipe 25. Then, the AC motor 4 is started to drive the rotating rod 6 to rotate. The rotation of the rotating rod 6 drives the rotating plate 14 to rotate. The two rotating shafts 15 on the bottom surface of the rotating plate 14 rotate together with the rotating plate 14. Since the third gear 16 meshes with the gear ring 13, while the rotating shaft 15 revolves around the rotating rod 6, the third gear 16 will roll on the gear ring 13, driving the rotating shaft 15 to rotate. This causes the rotating scraping head 17 at the bottom of the rotating shaft 15 to rotate, which can rotate and scrape the inner wall of the slurry storage tank 2.
[0044] The stirring head 7 at the bottom of the rotating rod 6 rotates accordingly, scraping the bottom surface of the slurry tank 2. It works in conjunction with the rotating scraping head 17 to complete the cleaning work. The water tank 22 can be filled with water through the water inlet pipe 26. The adapter 27 can be used to connect different types of pipes.
[0045] The slurry can be fully stirred by the coordinated stirring of the stirring head 7, the defoaming plate 11, the rotating scraping head 17, and the scraper 18, avoiding the local vortex and material agglomeration problems that are easy to occur in traditional blade mixers, improving the uniformity of the slurry and ensuring the grouting strength.
[0046] The defoaming tank 12 on the defoaming plate 11 can effectively break the air bubbles in the grout during the mixing process, reduce the voids formed by the bursting of air bubbles after grouting, improve the reinforcement effect, and avoid problems such as honeycomb structure in foundation grouting.
[0047] The stirring speed can be adjusted by the frequency converter 5, which can meet the sensitive requirements of chemical slurry for stirring speed and prevent it from solidifying prematurely. At the same time, sufficient stirring force can avoid the situation where particles in granular slurry settle and block the pipeline.
[0048] The scraper 18 prevents the slurry from sticking to the inner wall of the slurry storage tank 2. The rotation of the scraper head 17, combined with the water pump 23, allows for a thorough cleaning of the inside of the device, reducing dead corners in the mixing chamber and preventing the slurry from solidifying and forming hard blocks that can jam the mixing head 7. It also prevents residual slurry from contaminating subsequent mixing, ensuring the adaptive adjustment accuracy of subsequent devices, facilitating maintenance and operation, and improving the quality and efficiency of grouting operations.
[0049] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
