Description

Technical Field

[0001] This utility model belongs to the field of grouting engineering, and in particular relates to an integrated equipment for grout mixing and grouting. Background Technology

[0002] Curtain grouting is a grouting process that involves injecting grout into fissures and pores in rock or soil layers to form a continuous water-blocking curtain, thereby reducing seepage flow and lowering seepage pressure, thus achieving waterproofing and reinforcement. Since the 20th century, curtain grouting has been a primary method for seepage prevention treatment of hydraulic structures' foundations, playing a crucial role in ensuring the safe operation of hydraulic structures.

[0003] As the market demands increasingly higher quality and precision in foundation treatment construction, existing grouting equipment can no longer meet modern construction requirements. Traditional grouting equipment occupies a large area and is inconvenient to move. Furthermore, the grouting materials required by this equipment necessitate the use of complementary devices, which not only increases the complexity and cost of the equipment but also, due to its large footprint, can cause inconvenience to the construction environment, especially in situations with limited space or frequent relocation of the construction site. In addition, the operation and maintenance of this equipment can be relatively complex, requiring specialized technicians, further increasing the cost and difficulty of construction.

[0004] To overcome the problems of large footprint and inconvenience in traditional curtain grouting construction, the industry may take some improvement measures, such as developing more compact and efficient equipment, and exploring modular design for rapid assembly and disassembly to improve construction efficiency and transportation convenience.

They are only for the convenience of describing this utility model and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0020] like Figure 1-2As shown, an integrated grout mixing and grouting device includes a base plate 19. A support component 9 is provided at the bottom of the base plate 19. The support component 9 includes a support block 906 that can slide up and down for support and a driving device for driving the support block 906 to slide up and down. A grouting tank 8 is fixedly mounted on the top of the base plate 19. A mixing tank 2, which is connected to the base plate 19, is fixedly mounted on the top of the grouting tank 8. A stirring device for mixing is rotatably mounted at the bottom of the grouting tank 8. The working end of the stirring device is located inside the mixing tank 2. A feeding component 3 is provided through the outer wall of the mixing tank 2. The bottom of the grouting tank 8 is connected to the grouting component. Materials enter the mixing tank 2 through the feeding component 3, and water enters the mixing tank 2 through the water supply pipe 1. After the mixed water and materials are stirred evenly by the stirring device, the mixture is fed into the grouting tank 8 through the bottom of the mixing tank 2 for later use, and then injected into the borehole 18 through the grouting head 17.

[0021] like Figure 1 As shown, the grouting assembly includes a grouting pump 12, a grouting conduit 14, a grouting head 17, and a return grouting conduit 15. The input end of the grouting pump 12 is connected to the inside of the grouting tank 8, and the output end of the grouting pump 12 is equipped with the grouting conduit 14. The output end of the grouting conduit 14 is equipped with the grouting head 17, and the return grouting conduit 15 is located near the output end of the grouting conduit 14. The output end of the return grouting conduit 15 is connected to the top of the grouting tank 8. A flow meter 13 is installed on the grouting conduit 14, and a flow meter 16 is installed on the return grouting conduit 15. After being pressurized by the grouting pump 12, the mixed grout is injected into the borehole 18 through the grouting head 17. Part of the grout returns to the grouting tank 8 through the return grouting conduit 15, maintaining the grout in a circulating flow state within the borehole section. Flow meters 13 and 16 are existing technologies and are used to measure the grouting volume and return grout volume, respectively.

[0022] like Figure 2As shown, the driving device includes a second motor 901, a drive rod 902, a worm gear 903, a worm wheel 904, and a transmission gear 905. The drive rod 902 is horizontally threaded through the base plate 19 and rotatably connected to it. The second motor 901 is fixed to one end of the base plate 19, and its output end is connected to the drive rod 902. Two worm gears 903 are provided along the length of the drive rod 902. A worm wheel 904, meshing with the worm gears 903, is rotatably mounted inside the base plate 19. A transmission gear 905 is fixed to one side of the worm wheel 904. A groove is provided at the bottom of the base plate 19, and a support block 906 is slidably mounted within the groove. A second rack 907 is vertically mounted on the support block 906, meshing with the transmission gear 905. When the second motor 901 rotates, it drives the worm gear 903 to rotate, which in turn drives the worm wheel 904 and the transmission gear 905, thereby driving the support block 906 to rise and fall. The support block 906 supports the entire device. When the device needs to be fixed after being moved to a certain position by the moving component 11, the support block 906 is lowered to contact the ground, thereby raising the entire device (the moving component 11 does not contact the ground), preventing the device from sliding and affecting operation. There are two implementations of the drive rod 902 and the support block 906. One implementation has a recessed portion in the middle of the support block 906 that adapts to the drive rod 902, so that the support block 906 is not obstructed by the drive rod 902 during its up-and-down sliding. The other implementation has the drive rod 902 located at one end of the support block 906, so that the support block 906 is not obstructed by the drive rod 902 during its up-and-down sliding.

[0023] In addition, the feeding assembly 3 includes a baffle 301, a motor 302, and a feeding trough 303; the feeding trough 303 is fixedly provided on the outer wall of the mixing tank 2, the input end of the feeding trough 303 is connected to the inside of the mixing tank 2, the output end of the feeding trough 303 is slidably provided with a baffle 301, the baffle 301 is provided with a rack in the vertical direction, the top of the feeding trough 303 is fixedly provided with a motor 302, and the output end of the motor 302 is provided with a gear that meshes with the rack. The mixing tank 2 is equipped with a level gauge 4, which is electrically connected to a motor 302. The level gauge 4 is used to monitor the amount of slurry in the mixing tank 2. The level gauge 4 is electrically connected to the motor 302 and the switch of the water supply pipe 1. When the amount of slurry is insufficient, the motor 302 drives the baffle 301 to slide upward to allow the material to enter the mixing tank 2. At the same time, the switch of the water supply pipe 1 is opened to supply water. When the amount of slurry is sufficient, the motor 302 drives the baffle 301 to slide downward to prevent the material from entering. At the same time, the switch of the water supply pipe 1 is cut off. In one embodiment, the baffle 301 and the output end of the feed trough 303 are provided with a certain damping to prevent them from sliding downward due to their own weight. The stirring device includes stirring blades 5 and a rotating rod 6. The rotating rod 6 is rotatably and vertically mounted at the bottom of the grouting tank 8. Multiple sets of blades 5 are evenly fixed along the length of one end of the rotating rod 6 located inside the mixing tank 2. The stirring device is used to mix the material and water to form a slurry. One end of the rotating rod 6 is connected to the output end of the motor to drive its rotation. A water supply pipe 1 is rotatably mounted on the top of the mixing tank 2. The output end of the water supply pipe 1 is bent, allowing it to rotate around the vertical axis during rotation to increase the direct contact area with the material. A control valve 7 is fixedly mounted at the connection between the mixing tank 2 and the grouting tank 8. A level gauge 2 10 is installed inside the grouting tank 8, and the level gauge 2 10 is electrically connected to the control valve 7. When the material is still mixing with water, the control valve 7 is closed to prevent unmixed material from entering the mixing tank 2. Multiple sets of moving components 11 are evenly arranged around the circumference of the base plate 19. Each moving component 11 includes a rotatable support frame 1102 mounted on the bottom of the base plate 19, and a rotatable roller 1101 is mounted on the bottom of the support frame 1102.

[0024] Working principle: During the batching stage: Control valve 7 is closed, baffle 301 is at a high position, and materials enter the batching tank 2 through the feed chute 303. Simultaneously, water supply pipe 1 supplies water to the batching tank 2 in proportion. At the same time, the mixing device starts working, mixing the materials evenly for grouting. When the liquid level in the batching tank 2 reaches the predetermined value, motor 1 302 controls the baffle 301 to slide downwards to block material from entering, and the water supply pipe 1 is switched off to stop water supply. During the storage stage: Control valve 7 is opened, and grout flows from the bottom of the batching tank 2 into the grouting tank 8. When the grout level in the grouting tank 8 reaches the predetermined value, control valve 7 is closed. During the usage stage: Grouting pump 12 starts working, and grout is delivered to the grouting head 17 through the grouting conduit 14. The grouting head 17 delivers the grout into the borehole 18, and some of the grout is returned to the grouting tank 8 through the return grout conduit 15.

[0025] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Any modifications, alterations, alterations, or substitutions made by those skilled in the art to the technical solutions of the present utility model without departing from the spirit of the present utility model shall fall within the protection scope defined by the claims of the present utility model.
