Technical Field

[0001] This invention relates to the field of highway subgrade construction, and in particular to a grouting reinforcement device for highway subgrade construction. Background Technology

[0002] In highway subgrade construction, grouting reinforcement is a crucial method for improving the subgrade's bearing capacity and stability. Traditional grouting methods typically employ separate mixing and grouting equipment, which suffers from problems such as large equipment size, inconvenient mobility, low mixing efficiency, and easy sedimentation or clogging of grouting materials. Especially in complex construction site conditions with limited space, existing equipment struggles to flexibly adjust mixing depth and container capacity, failing to adapt to grouting needs of varying scales. Furthermore, material tends to accumulate at the discharge port during grouting, affecting the continuity of grouting, and there is a lack of effective road surface leveling auxiliary structures. Therefore, there is an urgent need for a grouting reinforcement device with a reasonable structure, convenient operation, and strong adaptability to improve the efficiency and quality of highway subgrade grouting construction. Summary of the Invention

[0021] The present invention will now be described in detail with reference to the accompanying drawings, such as... Figure 1-6As shown, a grouting reinforcement device for highway subgrade construction includes a bracket 1, with self-locking first universal wheels 2 installed on both sides of the bracket 1, a slot is opened in the bracket 1, a rectangular frame 3 is inserted in the slot, a mixing structure is installed on the bracket 1, and a load-bearing mixing structure is installed on the rectangular frame 3.

[0022] like Figure 1-2 As shown, it should be noted that: bracket 1 serves as a support to support the first universal wheel 2 with self-locking. The first universal wheel 2 with self-locking facilitates the flexible movement of this device and can also lock its position. The mixing structure on the rectangular frame 3 facilitates the mixing of the grout. The mixing structure can carry materials and allow the mixing structure to mix the grout.

[0023] The stirring structure is as follows: a positioning rod 4 is installed on the upper wall of the bracket 1 near the four corners. A support column 5 is installed on the positioning rod 4. The top of the support column 5 is provided with a slot. A slot 6 is installed in the slot. A first connecting frame 7 is installed between the slots 6. A drive mounting seat 8 is installed on the first connecting frame 7. A servo motor 9 is installed on the drive mounting seat 8. A first connecting rod 10 is installed on the drive end of the servo motor 9. Multiple threaded first short rods 11 are installed on the first connecting rod 10. A tube 12 is installed on one of the first short rods 11. An arc rod 13 is installed on the tube 12. Multiple threaded stirring rods 14 are installed on the arc rod 13. The lowest first short rod 11 has a thin rod 15 fixed at its lower end. An inclined plate 16 is installed on the thin rod 15.

[0024] It should be noted that: the positioning rod 4 installed on the upper wall of bracket 1 serves as a support, facilitating the installation of support column 5. Support column 5 can be moved up and down to adjust its installation position, thereby adjusting the usage height. The slot on support column 5 facilitates the installation of the mounting base 6, and the first connecting bracket 7 on the mounting base 6 provides support for the drive mounting base 8. The servo motor 9 on the drive mounting base 8 can rotate, driving the first short rod 11 on the drive end to rotate. The first short rod 11 is extended sequentially through threaded connections, allowing for easy disassembly and length adjustment. After threaded connection, the joints are fixed with bolts to prevent loosening. The insertion tube 12... The arc-shaped rod 13 can be installed and extended sequentially through threaded connection, allowing for easy disassembly and length adjustment. After threaded connection, the connection is fixed with bolts to prevent loosening and affecting use. The stirring rod 14 on the arc-shaped rod 13 facilitates stirring of materials within the carrying and mixing structure. The number of arc-shaped rods 13 and the first short rod 11 can be increased to facilitate subsequent operation according to actual conditions. The thin rod 15 is inserted into the discharge pipe 20, and the inclined plate 16 on the thin rod 15 facilitates scraping the inside of the discharge pipe 20. When the servo motor 9 drives the rotation, it drives the stirring to rotate. At the same time, the inclined plate 16 on the thin rod 15 rotates to prevent material from accumulating and not falling.

[0025] like Figure 1 , 2 As shown in Figure 3, the load-bearing hybrid structure is as follows: a folded frame 17 is installed on the rectangular frame 3, a hemispherical shell 18 is installed on the folded frame 17, a first annular groove is provided on the hemispherical shell 18, an arc-shaped support plate is provided on the annular groove, a pair of arc-shaped support plates are joined together to form a sleeve 19, a second annular groove is provided on each sleeve 19 to facilitate the stacking of multiple sleeves 19, a discharge port is provided on the lower wall of the hemispherical shell 18, a discharge pipe 20 is inserted into the discharge port, a control valve is installed on the discharge pipe 20, a water inlet is provided on the sleeve 19, a water inlet pipe 21 is inserted into the water inlet, a first control valve 22 is installed on the water inlet pipe 21;

[0026] It should be noted that: the rectangular frame 3 serves as a support to support the folding frame 17. The hemispherical shell 18 on the folding frame 17 facilitates the accumulation of materials inside. After being connected by the arc-shaped support plate, a sleeve 19 is formed to increase the internal space of the hemispherical shell 18, which facilitates the increase of the material accumulation area. After increasing the number of sleeves 19, the first short rod 11 and the arc rod 13 on the stirring structure are increased, thereby increasing the length of the stirring structure and facilitating the mixing of materials. The discharge pipe 20 facilitates the discharge of the stirred materials, and the water inlet pipe 21 facilitates the filling of water into the structure.

[0027] As a preferred technical solution, the positioning rod 4 is provided with a strip-shaped notch, the support column 5 is provided with a fourth threaded opening, the strip-shaped notch is provided with a third threaded groove that matches the fourth threaded opening, and a third screw 25 that matches the third threaded groove is inserted into the fourth threaded opening; the use of the third screw 25 makes it easy to fix the support column 5, thereby making it easy to fix and install after the position and height of the support column 5 are adjusted.

[0028] As a preferred technical solution, further, the sleeve 19 is provided with a strip-shaped lug 26, the strip-shaped lug 26 has a limiting opening, the rectangular frame 3 has a limiting groove that matches the limiting opening, and a guide rod 27 inserted into the limiting groove is inserted into the limiting opening; such as Figure 3 As shown, the strip-shaped lug 26 can be observed through the guide rod 27, which facilitates temporary positioning of the sleeve 19 after installation.

After the sleeve 19 is installed, it can be placed on the sleeve 19, or it can be placed directly on the hemispherical shell 18 without being placed on the sleeve 19.

[0030] As a preferred technical solution, furthermore, the sleeve 19 is equipped with first arc-shaped gaskets 30 on both the upper and lower parts, and the first arc-shaped gaskets 30 have first mounting holes. The hemispherical shell 18 is provided with second arc-shaped gaskets 31, and the second arc-shaped gaskets 31 have second mounting holes that match the first mounting holes; for example... Figure 3 , 5 As shown, it should be noted that: after the first arc-shaped gasket 30 on the sleeve 19 is connected, it is fixed to facilitate the stable use of the sleeve 19. Furthermore, the first arc-shaped gasket 30 and the second arc-shaped gasket 31 on the sleeve 19 are fixedly installed to achieve the fixed use of the sleeve 19.
