A foundation that can meet the requirements of a building without artificial treatment is called a natural foundation, and a foundation that requires artificial reinforcement to meet the requirements of a building is called an artificial foundation. Foundation and subgrade engineering requires injecting concrete mortar into the interior of the formwork to complete.

A support plate is arranged on the mounting plate, and a clamping seat is arranged on the support plate. The clamping seat includes two semi-circular bases, and the two bases are hinged. A locking buckle that engages with each other is arranged on the side of the base away from the hinge; a groove is formed on the inner surface of the base, a fitting sleeve is arranged in the groove, an adjustment groove is formed on the fitting sleeve, and an elastic component is arranged in the adjustment groove; a fixed pipe is arranged in the fitting sleeve, and a plurality of sliding seats are arranged on the outer surface of the fixed pipe. In the present utility model, the mounting plate is fixed by a fastening groove and a fastening bolt. The outer surface of the grouting pipe of a concrete truck is sleeved with the fixed pipe. Then, the base is opened, the sliding seats of the fixed pipe are placed on the inner wall of the fitting sleeve, and the locking buckle of the base is used for installation. The device is convenient and fast to install and has good use stability.

[0004] In view of the above related technologies, the inventor found the following defects: In the currently existing grouting devices, if the grouting pipeline is not cleaned in time during use, the interior will be blocked by concrete, affecting the subsequent injection of concrete mortar. Moreover, the larger particles in the mortar have a slower feeding speed and are prone to accumulation, affecting the grouting work of the concrete. Summary of the Utility Model

Detailed Description of the Embodiments

[0022] The following further describes the present application in detail with reference to the Figures 1-4 drawings.

[0023] An embodiment of the present application discloses a grouting device for foundation and subgrade engineering. As Figure 1 shown, it includes a base plate 1. One end of the upper surface of the base plate 1 is fixedly provided with an arc-shaped support rod 17. The top of the arc-shaped support rod 17 is fixedly provided with a power box 12. Both ends of the inner wall of the power box 12 are rotatably inserted with a rotating shaft 3. A semi-tooth gear 6 is fixedly sleeved on the outer circumferential surface of the rotating shaft 3 near the top.

[0024] Please refer to Figure 2 , there are two semi-tooth gears 6. The two semi-tooth gears 6 are sequentially meshed with the teeth on both sides of the rectangular rack 14. One-half of the outer circumferential surface of the semi-tooth gear 6 is set as a smooth surface. By sequentially meshing the two semi-tooth gears 6 with the rectangular rack 14, when the two semi-tooth gears 6 rotate coaxially, the rectangular rack 14 can still move in two directions with a gap. The semi-tooth gear 6 is meshed with a rectangular rack 14 through the teeth on one side.

[0025] Please refer to Figure 1, a fixing plate 11 is fixedly arranged at the middle position of the top of the rectangular rack 14. A sliding rod 13 is fixedly inserted at the top of the fixing plate 11. Both ends of the sliding rod 13 are slidably inserted at the middle position near the top of the power box 12. The fixing plate 11 at the top of the rectangular rack 14 drives the sliding rod 13 to slide on the top of the power box 12, ensuring the stability of the rectangular rack 14 during movement. One end of the rectangular rack 14 passes through one side of the power box 12 and is fixedly provided with a vibration ring 7.

[0026] Please refer to Figure 1 , the inner diameter of the inner wall of the vibration ring 7 is the same as the diameter of the blanking pipe 5. The vibration ring 7 is arranged in an elliptical shape. The number of the vibration rings 7 is two. The two vibration rings 7 are respectively sleeved on the outer side of the blanking pipe 5. The left and right sides of the inner walls of the two vibration rings 7 are alternately slidably connected to the outer wall of the blanking pipe 5. The elliptical vibration ring 7 facilitates knocking on the outer wall of the blanking pipe 5 during left and right movement, enabling the blanking pipe 5 to vibrate, ensuring the smooth dropping of the mortar inside the blanking pipe. The blanking pipe 5 is slidably inserted into the inner wall of the vibration ring 7.

[0027] Please refer to Figure 3 , the number of the blanking pipes 5 is two. Metal bellows 2 are fixedly arranged at the bottoms of the two blanking pipes 5. A connecting clamp 18 is arranged at the bottom of the metal bellows 2. A reverse funnel-shaped pipe orifice is fixedly arranged at the top of the blanking pipe 5. The metal bellows 2 facilitate changing the direction of the pipeline, enabling the concrete mortar to be grouted in multiple directions as needed during injection. At the same time, the connecting clamp 18 facilitates connection with the grouting pipeline, preventing mortar leakage. The blanking pipe 5 is arranged parallel to the power box 12.

[0028] Please refer to Figure 1 , support plates 10 are arranged at both the upper and lower ends of the power box 12. A horizontal shaft 9 is fixedly inserted in the middle of the support plate 10. Fixed rings 8 are fixedly arranged at both ends of the horizontal shaft 9. The middle parts of the fixed rings 8 are fixedly sleeved on the outer circumferential surfaces at both ends of the blanking pipe 5. The power box 12 fixes the blanking pipe 5 through the support plates 10 and the horizontal shaft 9, avoiding the shaking of the blanking pipe 5 during work and preventing the concrete mortar from falling off during injection.

[0029] Please refer to Figure 2 , a first straight gear 4 is fixedly sleeved in the middle of the rotating shaft 3. The number of the first straight gears 4 is two. The two first straight gears 4 are respectively meshed on both sides of the second straight gear 16. The middle parts of the two first straight gears 4 are both inserted with the rotating shaft 3. By arranging the two identical first straight gears 4 on both sides of the second straight gear 16, it is realized that under the action of the second straight gear 4, both of the two first straight gears 4 can rotate. The first straight gear 4 is meshed with the second straight gear 16 through the teeth on one side of the outer circumferential surface. A motor 15 is fixedly inserted in the middle of the second straight gear 16. The bottom of the motor 15 is fixedly arranged at the middle position of the bottom of the power box 12.

[0030] The implementation principle of the grouting equipment for a foundation and subgrade engineering in an embodiment of this application is as follows: When in use, when the grouting work starts and the funnel-shaped part at the top of the feeding pipe 5 is connected to the external concrete pipe, the motor 15 is started as the power, and the rotating shaft 3 is driven to rotate through the cooperation of two spur gears. The rotating shaft 3 drives the semi-toothed gear 6 to perform a circular motion. When the two semi-toothed gears 6 perform a circular motion, they are successively engaged with the teeth on both sides of the rectangular rack 14. The toothed rack 14 moves reciprocally left and right under the action of the semi-toothed gear 6. The rectangular rack 14 drives the two vibration rings 7 to move outside the two feeding pipes 5 on both sides. When the vibration rings 7 come into contact with the outside of the feeding pipe 5 multiple times, the feeding pipe 5 is vibrated, thereby preventing the internal concrete mortar from accumulating inside the feeding pipe 5, ensuring the smoothness inside the feeding pipe 5. At the same time, the metal bellows 2 at the bottom of the feeding pipe 5 facilitates the multi-angle rotation of the mortar pipe outlet below.

[0031] The above are all the preferred embodiments of this application. Without restricting the protection scope of this application based on this, therefore: All equivalent changes made according to the structure, shape, and principle of this application shall be covered within the protection scope of this application.
