[0002] Reinforced concrete is the largest building material used by humans and has been widely used in houses, roads, bridges, hydraulic engineering, marine engineering and other projects. However, due to its shortcomings such as high brittleness and low tensile strength, concrete often inevitably cracks due to the influence of the surrounding environment during use. When the cracks exceed the specification limit, it will accelerate the damage to the structure and shorten the service life of the structure.

This application uses a micro air compressor as a power source. During the grouting process, grouting can be carried out in a gradually pressurized manner, which can effectively overcome the grouting difficulties caused by the reduction of the pressure source in the later grouting process. However, this application has the following limitations: the cracks cannot be cleaned before grouting, and there is no sealing means, so it is difficult to completely fill the cracks after grouting, and the sealing cannot be guaranteed.

[0019] In order to make the purpose, technical solution and advantages of the utility model clearer and more understandable, the technical solution of the utility model will be further described in detail below with reference to the accompanying drawings.
[0020] like Figure 1-Figure 4 As shown, the utility model provides a grouting device for crack filling, comprising a base 1, a crack cleaning unit, a plugging material molding mold unit and a grouting unit, wherein the crack cleaning unit, the plugging material molding mold unit and the grouting unit are all arranged on the base 1; the crack cleaning unit comprises a cutting machine 10 and a storage table, the storage table is fixedly mounted on the base 1, the cutting machine 10 can be arranged on the storage table, and the cutting machine 10 is used to clean the cracks; the plugging material molding mold unit can extrude and mold the plugging material through a mold; the grouting unit is used to grout into the cracks.
[0021] Before grouting, the device first removes the cutting machine 10 from the storage table and cleans the cracks. On the one hand, it can remove impurities in the cracks, and on the other hand, it can shape the cracks to a certain extent, making the crack opening smoother. Then, the engineering glue or other sealing materials are squeezed into shape through the sealing material molding mold unit to seal the crack opening. Finally, the cracks can be filled with grout through the grouting unit.
[0022] The storage table includes a fixed plate 2 and a transverse plate 11. The fixed plate 2 is fixedly installed on the base 1, and the transverse plate 11 is fixedly connected to the fixed plate 2. A hole 12 is opened on the transverse plate 11, and the handle of the cutting machine 10 can be inserted into the hole 12. A winding rod 13 is rotatably installed on the fixed plate 2 through a torsion spring. A steel wire rope 14 is wound on the winding rod 13, and the movable end of the steel wire rope 14 is connected to the handle of the cutting machine 10. A round rod 15 is fixedly installed on the top of the fixed plate 2, and a circular ring 16 is rotatably mounted on the circular rod 15. A limiting plate 17 is fixedly connected to the circular ring 16. The limiting plate 17 can interfere with the cutting machine 10 and thus limit the handle of the cutting machine 10 from being removed from the hole 12. A threaded rod 18 is slidably penetrated on the circular ring 16, and the bottom of the threaded rod 18 is inserted into the top of the fixed plate 2 through a threaded fit.
[0023] When using the cutting machine 10, the threaded rod 18 needs to be screwed first. Since the threaded rod 18 and the fixing plate 2 are threadedly matched, the threaded rod 18 can be rotated and unscrewed from the fixing plate 2. Then the user can turn the limit plate 17 so that the limit plate 17 is turned away from the top of the cutting machine 10. Then the handle of the cutting machine 10 can be taken out of the hole 12, and the cutting machine 10 can be used to clean the crack. Moreover, since the handle of the cutting machine 10 is connected to the wire rope 14, when the cutting machine 10 is taken out, the wire rope 14 will also be unwound from the winding rod. After the use of the cutting machine 10 is completed, it is only necessary to insert the handle of the cutting machine 10 into the hole 12, because the winding rod 13 is rotatably connected to the fixing plate 2 by the torsion spring, so under the action of the torsion spring, the winding rod 13 can continue to rotate to reel in the wire rope 14, so as to prevent the wire rope 14 from being dragged on the ground, and finally the limit plate 17 is moved so that the limit plate 17 continues to be above the cutting machine 10, and then the threaded rod 18 is screwed into the fixing plate 2.
[0024] The plugging material forming mold unit includes a lower mold 3, an upper mold 4, an electric push rod 19 and a baffle assembly. The lower mold 3 is fixedly installed on the base 1, and the upper mold 4 is arranged on the lower mold 3. The baffle assembly can limit the movement of the upper mold 4 relative to the lower mold 3. The electric push rod 19 is fixedly installed on the base 1. A push plate 20 is slidably arranged in the lower mold 3. The telescopic end of the electric push rod 19 slides through the bottom surface of the lower mold 3 and is fixedly connected to the push plate 20. The baffle assembly includes an annular plate 5 and an L-shaped clamping rod 6. The annular plate 5 is fixedly connected to the fixed plate 2. The annular plate 5 can be sleeved on the upper mold 4 and fit with the upper mold 4. There are at least two L-shaped clamping rods 6 that are evenly and equidistantly rotatably installed on the annular plate 5.
[0025] When extruding the plugging material, the user first needs to push the L-shaped clamping rod 6 to prevent the L-shaped clamping rod 6 from blocking the upper mold 4, and then remove the upper mold 4, place the engineering glue or other materials in the lower mold 3, and then pass the upper mold 4 through the annular plate 5 again and fit it on the lower mold 3, push the L-shaped clamping rod 6 to block the upper mold 4, and then start the electric push rod 19 to drive the push plate 20 to move in the lower mold 3 to extrude the plugging material. After completion, push the L-shaped clamping rod 6, remove the upper mold 4, and the formed plugging material can be taken out.
[0026] The grouting unit comprises a barrel 7 , a grouting tube 8 and a plurality of grouting nozzles 9 . The barrel 7 is fixedly mounted on the base 1 , the grouting tube 8 is detachably mounted on the base 1 , and the grouting nozzles 9 are detachably mounted on the barrel 7 .
[0027] The barrel 7 stores slurry. When grouting, several grouting nozzles 9 are removed and arranged on the crack at equal distances along the length direction of the crack. Then the grouting tube 8 is removed, and the slurry is extracted from the barrel 7. The grouting tube 8 is aligned with the grouting nozzles 9 in turn to inject grouting until the crack is filled.
[0028] In summary, the overall working process of the utility model is as follows: when working, the overall device is located at the position where it needs to work, the upper mold 4 is combined with the lower mold 3, the L-shaped clamping rod 6 is rotated to block the upper mold, the electric push rod 19 is started, and the material to block the crack is squeezed and formed, and then the threaded rod 18 is rotated to make the threaded rod 18 move upward and separate from the fixed plate 2, and then the ring 16 is rotated to make the limit plate 17 fixedly connected to the ring 16 rotate at the same time and move away from the top of the cutting machine 10, and then the cutting machine 10 is removed and placed near the crack, and the cutting machine 10 is used to block the crack. Clean the cracks to reduce impurities in the cracks. After completion, put the cutting machine 10 back to its original position, turn the limit plate 17 back to the top of the cutting machine 10 and screw the threaded rod 18 into the fixed plate 2, then turn the L-shaped clamping rod 6, remove the upper mold 4, take out the material in the lower mold 3, and put it in the cracks, and block the cracks with the material (note the reserved grouting holes). After completion, place the grouting nozzle 9 at the cracks along the direction of the cracks, and then use the grouting tube 8 to extract the slurry in the barrel 7, and then let the grouting tube 8 inject the slurry into the cracks through the grouting nozzle 9 in turn to fill the cracks completely.
