Technical Field
[0001] This utility model specifically relates to a grouting device applied to the strip-groove grouting method, belonging to the technical field of grouting devices. Background Technology
[0002] The strip trench grouting method is a grouting technique for reinforcing strip foundations or specific linear cracks. Its core is to achieve directional and segmented grouting by opening trenches and burying grouting pipes. When repairing foundation cracks, traditional grouting devices have some problems in practical applications, especially when using the strip groove grouting method. Existing grouting devices often lack an effective grout guiding mechanism, making it difficult for the grout to fill the interior of the foundation cracks evenly and fully during the grouting process. In particular, when grouting at the cracked borehole, the grout is prone to forming flow resistance in the pipe, resulting in some areas not receiving enough grout filling, thus affecting the repair effect. To address the aforementioned technical issues, a grouting device for use in the strip-groove grouting method is proposed. Summary of the Invention
[0003] The purpose of this invention is to address the shortcomings of existing technologies by providing a grouting device for the strip-groove grouting method. This device guides the grout at the outlet by having a guide member penetrate deep into the crack, making it easier for the grout to fill the crack and reducing dead zones in the grouting process.
[0004] A grouting device for use in strip-groove grouting includes a main body and a guiding mechanism. The main body includes a material tank and a material pump. The material pump is installed on one side of the material tank. The inlet of the material pump passes through the material tank. The outlet of the material pump is connected to a grout outlet pipe. A grout outlet head is installed at one end of the grout outlet pipe. The guiding mechanism includes a fixing component and a guiding component. The fixing component is threaded onto one side of the slurry outlet head. A sealing ring is fixedly connected inside the fixing component. A hollow part is integrally formed at the bottom of the fixing component. A locking part is integrally formed on one side of the hollow part. The guiding component passes through the locking part. A locking ring is threaded on the outer side of the locking part. Guide grooves are evenly distributed on the outer side of the guiding component.
[0005] Furthermore, a sealing plate is fitted on one side of the slurry outlet pipe, and a sealing strip is fixedly connected to the bottom of the sealing plate.
[0006] Furthermore, an adhesive sheet is fixedly connected to the bottom of the sealing plate.
[0007] Furthermore, the top of the material barrel is integrally formed with a feeding port, and a motor is installed on the top of the material barrel. The output shaft of the motor passes through the material barrel, and a stirring blade is installed at one end of the motor output shaft located inside the material barrel.
[0008] Furthermore, a connecting plate is provided on one side of the fixing member, a vibration motor is installed on one side of the connecting plate, and a second bolt is threadedly connected to one side of the connecting plate, with one end of the second bolt threadedly connected to the fixing member.
[0009] Furthermore, a fixing plate is fixedly connected to one side of the slurry outlet pipe, and two first bolts are threadedly connected inside the fixing plate, with one end of the first bolt threadedly connected to the sealing plate. Beneficial effects
[0010] This invention adds a guide component at the grout outlet, which penetrates deep into the crack to guide the grout, making it easier for the grout to fill the crack and reducing dead zones in the grouting process. The guide component is fixed by a fixing component, which allows for adjustment of the insertion depth as needed. The fixing component has a hollowed-out part to provide sufficient outlet space for the grout. After grouting, a vibration motor can be installed in the fixing component, which drives the guide component to vibrate, thereby vibrating and defoaming the grout. Attached Figure Description

[0016] As a technical optimization of this utility model, in order to seal the crack and reduce grout leakage, a sealing plate 19 is fitted on one side of the grout outlet pipe 14. A sealing strip 31 is fixedly connected to the bottom of the sealing plate 19. The sealing strip 31 is made of flexible silicone material and can be trimmed according to the shape and size of the crack. An adhesive sheet 32 is fixedly connected to the bottom of the sealing plate 19 to fix the position of the sealing plate 19. A fixing plate 17 is fixedly connected to one side of the grout outlet pipe 14. Two first bolts 18 are threadedly connected inside the fixing plate 17. One end of the first bolt 18 is threadedly connected to the sealing plate 19. The grout outlet pipe 14 is connected to the sealing plate 19 by the first bolt 18 and the fixing plate 17, thereby reducing the shaking of the grout outlet pipe 14 during the grouting process.
[0017] As a technical optimization of this utility model, in order to prevent the slurry inside the material tank 11 from coagulating, a motor 15 is installed on the top of the material tank 11. The motor 15 is model 60M-R6430C5-E. The output shaft of the motor 15 passes through the material tank 11. A stirring blade 16 is installed at one end of the output shaft of the motor 15 inside the material tank 11.
[0018] The guiding mechanism 20 includes a fixing member 21 and a guiding member 24. The fixing member 21 is threaded onto one side of the grout outlet head 22. A sealing ring 26 is fixedly connected inside the fixing member 21. The bottom of the fixing member 21 has an integrally formed hollow part 27. A locking part 28 is integrally formed on one side of the hollow part 27. The guiding member 24 passes through the locking part 28. The locking part 28 consists of three arc-shaped pieces arranged equidistantly in annular shape, with a certain gap between each arc-shaped piece. A locking ring 23 is threaded on the outer side of the locking part 28. After the locking ring 23 is connected to the locking part 28, it squeezes the locking part 28, causing the locking part 28 to contract inward. The outer side of the guiding member 24 has equidistantly distributed guide grooves 25. The guiding member 24 is made of flexible rubber and can be bent according to the shape of the crack. A hydrophobic coating is provided on the outer surface of the guiding member 24 to reduce grout residue after grouting.
[0019] As a technical optimization of this utility model, in order to reduce air bubbles inside the grout after grouting, a connecting plate 29 is provided on one side of the fixing member 21, and a vibration motor 33 is installed on one side of the connecting plate 29. The vibration motor 33 is model BLC0612. A second bolt 34 is threadedly connected to one side of the connecting plate 29, and one end of the second bolt 34 is threadedly connected to the fixing member 21.
[0020] Working principle: The slurry is injected into the feed tank 11 through the feed port 12. The motor 15 is started to drive the stirring blade 16 to rotate, continuously stirring the slurry.

The length of the fixing member 21 is adjusted according to the crack depth. A locking ring 23 is installed on the locking part 28, causing the locking ring 23 to squeeze the locking part 28 inward. The locking part 28 covers and squeezes the guide member 24, thereby fixing the guide member 24. The sealing strip 31 is adjusted according to the shape and size of the crack and inserted into the crack to seal it. The opening of the plate 19 is aligned with the grouting area. The grout outlet 22 and the guide 24 pass through the sealing plate 19. The guide 24 extends into the crack. The material pump 13 is started to discharge the grout through the grout outlet pipe 14 and the grout outlet 22, so that the grout flows along the guide 24, thereby filling the inside of the crack. By changing the position and depth of the guide 24 in the crack, the grout can fill the dead zone inside the crack. After grouting, the grout outlet 22 is separated from the fixing part 21. A connecting plate 29 is installed at the fixing part 21, so that the vibration motor 33 on one side of the connecting plate 29 contacts the guide 24. The vibration motor 33 drives the guide 24 to vibrate, and the grout in the crack is vibrated to defoam.
