Description

Technical Field

[0001] This utility model belongs to the field of building engineering technology, specifically, it relates to a device for injecting grouting material for the bottom void of concrete slabs. Background Technology

[0002] In concrete structures such as roads, floors, and airport runways, voids often appear at the bottom of the slab due to uneven foundation settlement and water erosion. Grouting reinforcement is one of the most effective methods to repair such defects. This involves injecting high-strength grout into the voids at the bottom of the slab through drilling to fill the voids and restore the slab's support.

[0003] Existing equipment typically has a single grouting output design, usually with only one main grouting pipe, allowing operation on only one grouting hole at a time. When dealing with large-area voids in projects such as large parking lots, airport runways, or highways, this single-point operation mode is extremely inefficient, has a long construction cycle, and occupies the work surface for an extended period, significantly impacting traffic or other site operations. Therefore, we propose a device for grouting materials for voids at the bottom of concrete slabs. Utility Model Content

[0004] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:

[0005] A device for injecting grouting material for voids at the bottom of concrete slabs includes a grout tank and a pump body. Four legs are mounted on the outer wall of the grout tank. A discharge pipe is connected to the bottom of the grout tank and is connected to the input end of the pump body. A main pipe is connected to the output end of the pump body. Four branch pipes are connected to the outer wall of the main pipe. L-shaped support plates are mounted on the inner walls of the legs. A conveying hose is connected to one end of each branch pipe. Four fixing columns are mounted on the inner side of the L-shaped support plate. Limiting components for blocking the conveying hose are provided at one end of the uppermost and lowermost fixing columns. A solenoid valve is installed in the pipeline of each branch pipe. A nozzle is connected to one end of each conveying hose.

[0006] In a preferred embodiment of this utility model, the limiting component includes a clamping plate and a pulling plate. A connecting shaft is installed at one end of the fixed column. A shaft hole is opened on the clamping plate, and the connecting shaft moves through the shaft hole. A retaining ring is provided on the outer side of the clamping plate and is fixedly sleeved on the outer wall of the connecting shaft. A connecting rod is installed on the inner side of the pulling plate. A rod hole is opened at one end of the connecting shaft, and the connecting rod is inserted into the rod hole. A spring is fixedly installed between one end of the connecting rod and the inner wall of the rod hole. A pin block is installed on the inner side of the pulling plate. A pin groove is opened between the retaining ring and the outer side of the clamping plate, and the pin block is inserted into the pin groove. By setting the clamping plate, the clamping plate can limit the material conveying hose wound on the fixed column.

[0007] In a preferred embodiment of this utility model, both the connecting rod and the rod hole are rectangular in shape, and the connecting rod and the rod hole are compatible. By setting the connecting rod to a rectangle, the pull plate can be limited on the connecting shaft.

[0008] In a preferred embodiment of this utility model, there are two pin blocks and two pin slots, and the pin blocks and pin slots are adapted to each other. By setting the pin blocks, the pin blocks can be inserted into the pin slots, thereby limiting and fixing the card plate.

[0009] In a preferred embodiment of this utility model, a handle is installed on the outer side of the outrigger, and a caster wheel is installed at the bottom of the outrigger.

[0010] In a preferred embodiment of this utility model, a motor is installed at the top of the slurry tank, and a rotating shaft is installed at the output end of the motor. The rotating shaft passes through the top of the slurry tank and is rotatably connected to the slurry tank through a bearing. Multiple stirring plates are fixedly installed on the outer wall of the rotating shaft. By starting the motor, the motor can drive the stirring plates to rotate through the rotating shaft, thereby causing the stirring plates to agitate the slurry inside the slurry tank.

[0011] Compared with the prior art, the present invention has the following advantages:

[0012] This utility model is equipped with multiple branch pipes, allowing simultaneous operation on multiple grouting holes, which significantly shortens the construction time for large-area void areas. Furthermore, the four fixed columns and clamps facilitate the storage and placement of the material delivery hoses, making it easy for personnel to use flexibly and highly practical.

The following embodiments are used to illustrate this utility model.

[0022] like Figures 1 to 5 As shown, an apparatus for injecting grouting material for voids at the bottom of concrete slabs includes a grout tank 1 and a pump body 4. Four support legs 2 are installed on the outer wall of the grout tank 1. A discharge pipe 3 is connected to the bottom of the grout tank 1. The discharge pipe 3 is connected to the input end of the pump body 4. A main pipe 5 is connected to the output end of the pump body 4. Four branch pipes 7 are connected to the outer wall of the main pipe 5. An L-shaped support plate 6 is installed on the inner wall of the support legs 2. A conveying hose 9 is connected to one end of the branch pipe 7. Four fixing columns 10 are installed on the inner side of the L-shaped support plate 6. A limiting component for blocking the conveying hose 9 is provided at one end of the uppermost and lowermost fixing columns 10. A solenoid valve 8 is installed in the pipeline of the branch pipe 7. A nozzle 21 is connected to one end of the conveying hose 9.

[0023] Furthermore, the limiting assembly includes a locking plate 11 and a pull plate 20. A connecting shaft 12 is installed at one end of the fixing post 10. A shaft hole 13 is opened on the locking plate 11, and the connecting shaft 12 moves through the shaft hole 13. A retaining ring 17 is provided on the outer side of the locking plate 11 and is fixedly sleeved on the outer wall of the connecting shaft 12. A connecting rod 14 is installed on the inner side of the pull plate 20. A rod hole is opened at one end of the connecting shaft 12, and the connecting rod 14 is inserted into the rod hole. A spring 16 is fixedly installed between one end of the connecting rod 14 and the inner wall of the rod hole. A pin block 18 is installed on the inner side of the pull plate 20. A pin groove 19 is opened between the retaining ring 17 and the outer side of the locking plate 11, and the pin block 18 is inserted into the pin groove 19.

[0024] The clamping plate 11 is provided so that it can limit the material conveying hose 9 wound on the fixed column 10.

[0025] Furthermore, both the connecting rod 14 and the rod hole are rectangular in shape, and the connecting rod 14 is compatible with the rod hole.

[0026] By setting the connecting rod 14 as a rectangle, the pull plate 20 can be limited on the connecting shaft 12.

[0027] Furthermore, there are two pin blocks 18 and two pin slots 19, and the pin blocks 18 and pin slots 19 are compatible.

[0028] In this design, a pin 18 is provided so that it can be inserted into a pin slot 19, thereby limiting and fixing the card plate 11.

[0029] Furthermore, a handle 22 is installed on the outer side of the outrigger 2, and a caster wheel is installed at the bottom of the outrigger 2.

[0030] Furthermore, a motor 23 is installed at the top of the slurry tank 1, and a rotating shaft 24 is installed at the output end of the motor 23. The rotating shaft 24 passes through the top of the slurry tank 1 and is rotatably connected to the slurry tank 1 through a bearing. Multiple stirring plates 25 are fixedly installed on the outer wall of the rotating shaft 24.

[0031] By starting the motor 23, the motor 23 can drive the stirring plate 25 to rotate through the rotating shaft 24, thereby causing the stirring plate 25 to stir the slurry inside the slurry tank 1.

[0032] The implementation principle of a device for injecting grouting material for the bottom of concrete slabs is as follows: During use, open the solenoid valve 8 corresponding to the branch pipe 7, then pull the pull plate 20 outwards. The pull plate 20 drives the connecting rod 14 to stretch the spring 16, causing the pull plate 20 to disengage the pin block 18 from the pin groove 19. Then, rotate the clamping plate 11 downwards, causing it to rotate 180°, so that the clamping plate 11 no longer limits the material delivery hose 9. Then, pull the material delivery hose 9 outwards, aligning the nozzle 21 with the grouting hole. Then, start the pump body 4, causing it to draw the grout from the grout tank 1 through the discharge pipe 3, then transport it to the main pipe 5, and then through the branch pipe 7 to the material delivery hose 9. Finally, the grout is sprayed into the injection hole through the nozzle 21 to fill the void area and restore the support of the plate. After use, the material delivery hose 9 is evenly wrapped around the outer wall of the four fixed columns 10, and then the clamping plate 11 is rotated upward to rotate 180°, so that the clamping plate 11 limits the material delivery hose 9 on the fixed column 10, thereby completing the storage and placement of the material delivery hose 9. Through the above structure, multiple branch pipes 7 are set up, allowing multiple injection holes to be operated at the same time, which significantly shortens the construction time of large-area void areas. Moreover, the four fixed columns 10 and the clamping plate 11 make it easy for personnel to store and place the material delivery hose 9, which is convenient for personnel to use flexibly and has strong practicality.
