Description

Technical Field

[0001] This utility model relates to the field of compaction grouting technology, and in particular to a compaction grouting device for municipal road construction. Background Technology

[0002] Compaction grouting refers to injecting a very thick grout into holes drilled in the foundation soil and squeezing it into the soil. Grout bubbles are formed at the injection site, and the diffusion of the grout compresses the surrounding soil. The grout completely replaces the soil within the grouting area, resulting in a large plastic deformation zone in the vicinity of the grouting area, while the soil in areas farther from the grout bubbles undergoes elastic deformation, thus significantly increasing the soil density.

[0003] However, in existing technologies, after the compaction grouting on the ground is completed, it is often necessary to clean the grout storage tank to prevent the grout from solidifying and clumping on the inner wall of the tank, which would affect the next use of the tank. However, the cleaning of the grout adhering to the inner wall of the storage tank is often done by rinsing with water. This cleaning method is not convenient for cleaning the stubborn grout adhering to the inner wall of the storage tank. As a result, it takes a long time to rinse the stubborn grout adhering to the inner wall of the storage tank, which is time-consuming and affects the cleaning efficiency of the storage tank. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies: cleaning the slurry adhering to the inner wall of the slurry storage tank often only involves rinsing with water. However, this method is inconvenient for cleaning stubborn slurry adhering to the inner wall of the slurry storage tank. As a result, when it is necessary to rinse the stubborn slurry adhering to the inner wall of the slurry storage tank, it is time-consuming and affects the cleaning efficiency of the slurry storage tank.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a municipal road construction compaction grouting device, comprising a movable push plate, a support ring fixed on the upper surface of the movable push plate, a grout storage tank fixed on the inner surface of the support ring, a grout pump fixed on the lower end of the grout storage tank on the surface of the movable push plate, and an extraction pipe and an injection pipe fixedly connected to the input and output ends of the grout pump, respectively, with one end of the extraction pipe and the injection pipe respectively penetrating and fixedly connected to the grout storage tank and the movable push plate, and a circular opening opened at the upper end of the grout storage tank, with the surface of the grout storage tank located at the circular opening. A connecting frame is fixedly connected to the top of the device, and a motor is fixed to the surface of the connecting frame. A rotating shaft is fixed to the output end of the motor, and stirring rods are fixed to both sides of the rotating shaft. A movable strip slides through the upper and lower ends of the stirring rods, and a connecting column is fixedly connected to one side surface of the movable strip. The connecting column slides through and connects with the stirring rod. A scraping plate is fixedly connected to one end of the connecting column. A locking column is fixedly connected to both sides of the movable strip at the sliding groove position of the stirring rod, and the locking column engages with the stirring rod. A mobile power supply is fixedly connected to one end of the upper surface of the movable push plate.

[0006] In a preferred embodiment, a push handle is fixedly connected to the rear surface of the movable push plate.

[0007] In a preferred embodiment, protective covers are fixedly connected to both the upper and lower ends of the connecting frame, and the rotating shaft is rotatably connected to the lower protective cover.

[0008] In a preferred embodiment, shielding plates are fixedly connected to the surface of the movable strip at both the upper and lower ends of the groove of the stirring rod.

[0009] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0010] This invention relates to a method for cleaning the inner wall of a slurry storage tank. A movable strip is manually controlled to move outwards from the tank, which in turn moves the connecting column and scraper. One end of the scraper is brought into contact with the inner wall of the tank. After the movable strip completes its movement, the inner locking post disengages from the stirring rod, while the outer locking post engages with the stirring rod. This locking post design ensures the stability of the movable strip before and after its movement. A motor then drives the rotating shaft and stirring rod to rotate, causing the movable strip, connecting column, and scraper to rotate together. This allows the scraper to continuously move along the inner wall of the tank, quickly scraping off the slurry adhering to it. During this process, a handheld water hose is used to flush water into the tank through the circular opening, effectively cleaning stubborn slurry adhering to the tank and significantly improving cleaning efficiency.

[0016] 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.

[0017] Example 1

[0018] like Figure 1-3As shown, this utility model provides a technical solution: a municipal road construction compaction grouting device, including a movable push plate 1, a support ring 3 fixed on the upper surface of the movable push plate 1, and a grout storage tank 4 fixed on the inner surface of the support ring 3. The grout storage tank 4 serves to store grout. With the help of the movable push plate 1, the grout storage tank 4 can be easily pushed and moved, thereby facilitating the transport of the grout storage tank 4 to the grouting position on the road. The support ring 3 allows the grout storage tank 4 to be installed at a distance from the upper end of the movable push plate 1, creating space between the movable push plate 1 and the grout storage tank 4. This allows the extraction pipe 5, the grout pump 6, and the grouting pipe 7 to be installed directly below the grout storage tank 4. The grout pump 6 is fixed on the surface of the movable push plate 1 at the lower end of the grout storage tank 4, and the grout pump 6... The input and output ends are respectively fixedly connected to an extraction pipe 5 and an injection pipe 7, and one end of the extraction pipe 5 and the injection pipe 7 are respectively fixedly connected to the slurry storage tank 4 and the movable push plate 1. By starting the slurry pump 6, the extraction pipe 5 extracts the slurry stored in the slurry storage tank 4. The extracted slurry is transported through the injection pipe 7 and injected into the grouting position on the ground to achieve compaction grouting treatment of a part of the road. The upper end of the slurry storage tank 4 has a circular opening, which allows the user to easily add slurry into the slurry storage tank 4. A connecting frame 8 is fixedly connected to the surface of the slurry storage tank 4 above the circular opening. The connecting frame 8 facilitates the fixed installation of the motor 9 above the circular opening, and the motor 9 is fixed to the surface of the connecting frame 8. A rotating shaft 10 is fixed to the output end of the motor 9, and stirring rods 11 are fixed to both sides of the rotating shaft 10. When the slurry storage tank 4 is transported to the road grouting site, the motor 9 is started to drive the rotating shaft 10 and stirring rods 11 to rotate, so that the stirring rods 11 can stir the slurry in the slurry storage tank 4, thereby effectively preventing the slurry from settling and producing sediment. This allows the extraction pipe 5, the slurry pump 6, and the grouting pipe 7 to work together to pump the slurry normally and avoid blockage. A movable strip 13 slides through the upper and lower ends of the stirring rod 11, and a connecting column 14 is fixedly connected to one side surface of the movable strip 13. The connecting column 14 slides through and connects to the stirring rod 11. A scraper 15 is fixedly connected to one end of the connecting column 14. The two sides of the movable strip 13 are located at... Each of the sliding groove positions of the stirring rod 11 is fixedly connected with a locking post 16, which engages with the stirring rod 11. Manually pushing the moving strip 13 controls the forward and backward movement of the connecting post 14 and the scraper plate 15. When the stirring rod 11 is stirring the slurry in the storage tank 4, the locking post 16 on the inner side of the moving strip 13 engages with the sliding groove of the stirring rod 11. At this time, the connecting post 14 is completely retracted into the stirring rod 11, and the scraper plate 15 does not contact the surface of the storage tank 4. This effectively prevents the scraper plate 15 from continuously scraping the inner wall of the storage tank 4 during non-cleaning stages, reducing wear on the inner wall of the storage tank 4. When cleaning of the inner wall of the storage tank 4 is required, the moving strip 13 is manually moved towards the outside of the storage tank 4.This causes the connecting column 14 and the scraper 15 to move, so that one end of the scraper 15 comes into contact with the inner wall of the slurry tank 4. After the moving strip 13 completes its movement, the inner locking post 16 disengages from the stirring rod 11, while the outer locking post 16 engages with the stirring rod 11. The locking post 16 ensures the stability of the moving strip 13 before and after its movement. Then, the motor 9 drives the rotating shaft 10 and the stirring rod 11 to rotate, causing the moving strip 13, the connecting column 14, and the scraper 15 to rotate together. The scraper 15 continuously moves along the inner wall of the slurry storage tank 4 to quickly scrape off the slurry adhering to it. During this process, a handheld water hose is used to flush water into the slurry storage tank 4 through the circular opening, achieving rapid cleaning of stubborn slurry adhering to the tank and effectively improving cleaning efficiency. A mobile power supply 18 is fixedly connected to one end of the upper surface of the movable push plate 1. The mobile power supply 18 is electrically connected to the slurry pump 6 and the motor 9, facilitating power supply to the slurry pump 6 and the motor 9 outdoors.

[0019] Example 2

[0020] like Figure 1-3 As shown, a push handle 2 is fixedly connected to the rear surface of the movable push plate 1. The user can push the movable push plate 1 by holding it on the surface of the push handle 2 to facilitate the movement of the movable push plate 1. Protective covers 12 are fixedly connected to the upper and lower ends of the connecting frame 8, and the rotating shaft 10 is rotatably connected to the lower protective cover 12. With the help of the protective cover 12, the motor 9 installed on the connecting frame 8 is covered for protection. When slurry is poured into the slurry tank 4 from the circular opening at the top of the slurry tank 4 for storage, it is effectively prevented that the slurry will be accidentally spilled onto the motor 9 and affect its normal use. The surface of the movable strip plate 13 is fixedly connected to the upper and lower ends of the groove of the stirring rod 11. The setting of the protective cover 17 covers the upper and lower ends of the groove of the stirring rod 11, effectively preventing the slurry in the slurry tank 4 from entering the locking hole on the groove of the stirring rod 11 and thus affecting the normal connection between the locking post 16 and the locking hole on the groove of the stirring rod 11.

[0021] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
