[0026] Reference Figures 1-5 This utility model embodiment discloses a device for reinforcing weak foundations by carbonizing micro-nano CO2 with magnesium oxide. It includes an installation plate 1 located inside the foundation and a gas storage tank 20, a micro-nano bubble generator 21, a delivery pump 22, a storage tank 23, a water storage tank 25, and a winch 19 located on the ground.

[0027] The mounting plate 1 is placed inside the pile hole. The position of the movable plate 2 is adjusted so that the roller 3 contacts the foundation surface. Tightening the nut will enable the positioning operation of the movable plate 2, so that the mounting plate 1 is stably installed inside the pile hole without shaking, and is responsible for supporting other components and providing a stable working platform.

[0028] The material conveying assembly includes a first conveying pipe 5 rotatably connected to the middle of the mounting plate 1, a rotary joint 8 fixedly connected to the top of the first conveying pipe 5, a second conveying pipe 9 fixedly connected to the top of the rotary joint 8, a third conveying pipe 14 located on one side of the second conveying pipe 9, a fourth conveying pipe 15 located on one side of the second conveying pipe 9 and opposite to the third conveying pipe 14, two second discharge pipes 16 fixedly connected to the bottom of the third conveying pipe 14, two third discharge pipes 17 fixedly connected to the bottom of the fourth conveying pipe 15, two first discharge pipes 6 fixedly connected to the bottom of the first conveying pipe 5, and a drive assembly located on the top of the mounting plate 1 for driving the first conveying pipe 5 to rotate. Multiple discharge nozzles 7 are fixedly connected at equal intervals on one side of each of the first discharge pipes 6. The drive assembly includes a motor 10 fixedly connected to the top of the mounting plate 1 and two gears 11. The two gears 11 are respectively fixedly connected to the output shaft of the motor 10 and the outside of the first conveying pipe 5. The rotation of the first conveying pipe 5 is achieved by the operation of the motor 10 driving the gears 11 to rotate.

[0029] Micro-nano CO2 bubbles inside the second conveying pipe 9 are fed into the foundation through the first conveying pipe 5, the first discharge pipe 6, and the discharge nozzle 7. The rotation of the first conveying pipe 5 drives the first discharge pipe 6 and the discharge nozzle 7 to rotate, which facilitates the uniformity of the micro-nano CO2 bubble feeding and also provides a stirring effect. Magnesium oxide curing agent inside the third conveying pipe 14 is conveyed into the foundation through the second discharge pipe 16, and water inside the fourth conveying pipe 15 is conveyed into the foundation through the third discharge pipe 17. After the micro-nano bubbles mix with the magnesium oxide, a reaction occurs, forming stable solid carbides, thereby reinforcing the weak foundation.

[0030] The top of the mounting plate 1 is equipped with a steel cable 18 connected to the winch 19. The second conveying pipe 9 is connected to the micro-nano bubble generator 21, the third conveying pipe 14 is connected to the storage tank 23, and the fourth conveying pipe 15 is connected to the water storage tank 25. The gas storage tank 20 is filled with CO. 2， The storage tank 23 is filled with magnesium oxide. There are three delivery pumps 22.

[0031] The winch 19 uses steel cable 18 to stably lift or lower the mounting plate 1 and the equipment on it, ensuring that the equipment can accurately reach different depths of the foundation for reinforcement work. CO2 in the gas storage tank 20 is fed into the micro / nano bubble generator 21 to generate micro / nano CO2 bubbles, which are then transported to the first delivery pipe 5 via the delivery pump 22, connecting pipe 24, and second delivery pipe 9. Magnesium oxide fixative is transported to the third delivery pipe 14 via the delivery pump 22 and connecting pipe 24, and water is transported to the fourth delivery pipe 15 via the delivery pump 22 and connecting pipe 24.

[0032] The top plate 13 is mounted on the top of the mounting plate 1 by two fixing rods 12. The bottom end of the steel cable 18 is fixedly connected to the top plate 13. The second conveying pipe 9, the third conveying pipe 14 and the fourth conveying pipe 15 are all fixedly connected inside the top plate 13. The bottom ends of the second discharge pipe 16 and the third discharge pipe 17 are located between the first discharge pipe 6 and the bottom of the mounting plate 1 to avoid contact with the rotating first discharge pipe 6.

[0033] The top plate 13 facilitates the connection between the steel cable 18 and the mounting plate 1, and enables the fixation of the second conveying pipe 9, the third conveying pipe 14 and the fourth conveying pipe 15, ensuring their stability.

[0034] The first discharge pipe 6 rotates counterclockwise when viewed from above to prevent the discharge nozzle 7 from directly contacting the mixture during rotation, thus facilitating smooth gas discharge. Furthermore, each discharge nozzle 7 is equipped with a one-way valve to ensure unidirectional gas flow.

[0035] Working principle: The mounting plate 1 is placed inside the pile hole. The position of the movable plate 2 is adjusted so that the roller 3 contacts the foundation surface. Tightening the nut will realize the positioning operation of the movable plate 2, so that the mounting plate 1 is stably installed inside the pile hole without shaking. It is responsible for supporting other components and providing a stable working platform.

[0036] CO2 in the gas storage tank 20 is fed into the micro-nano bubble generator 21 to generate micro-nano CO2 bubbles, which are then transported to the first delivery pipe 5 via the delivery pump 22, connecting pipe 24, and second delivery pipe 9. Magnesium oxide fixative is transported to the third delivery pipe 14 via the delivery pump 22 and connecting pipe 24, and water is transported to the fourth delivery pipe 15 via the delivery pump 22 and connecting pipe 24.

[0037] Micro-nano CO2 bubbles inside the second conveying pipe 9 are fed into the foundation through the first conveying pipe 5, the first discharge pipe 6, and the discharge nozzle 7. The rotation of the first conveying pipe 5 drives the first discharge pipe 6 and the discharge nozzle 7 to rotate, which facilitates the uniformity of the micro-nano CO2 bubble feeding and also provides a stirring effect. Magnesium oxide curing agent inside the third conveying pipe 14 is conveyed into the foundation through the second discharge pipe 16, and water inside the fourth conveying pipe 15 is conveyed into the foundation through the third discharge pipe 17. After the micro-nano bubbles mix with the magnesium oxide, a reaction occurs, forming stable solid carbides, thereby reinforcing the weak foundation. Simultaneously, the winch 19 uses steel cables 18 to stably lift or lower the mounting plate 1 and the equipment on it, ensuring that the equipment can accurately reach different depths of the foundation for reinforcement work.

[0038] The device for reinforcing weak foundations using micro-nano CO2 and magnesium oxide carbonization in this embodiment has a simple and reasonable structure and is easy to operate. Through an optimized conveying and mixing process, it can quickly complete the reinforcement work, effectively enhance the bearing capacity of weak foundations, and improve engineering efficiency.

However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
