[0002] Soft soil layers with high compressibility often contain a certain amount of organic matter. Due to their low strength and large settlement, soft soil often poses a great threat to road engineering. If not handled properly, it can have a significant impact on the construction and use of highways. Therefore, soft soil foundations need to be reinforced by reinforcement structures before use.

[0003] Patent document CN219690475U discloses a soft soil foundation reinforcement structure, which discloses that "an installation tube is sleeved on the outer peripheral surface of the connecting screw, the installation tube is threadedly engaged with the connecting screw, a limit groove is opened on the inner wall of the installation groove, a limit block is fixed on the outer peripheral surface of the installation tube and slides with the limit groove, and a rotating component for driving the connecting screw to rotate is provided on the pipe pile. This application can make the connection between the pipe pile and the soft soil foundation more stable."

[0004] However, the reinforcement structures mentioned in the above-mentioned documents mainly consider the problem of unstable connection between existing reinforcement structures and soft soil foundations. However, the reinforcement structures are fixed in the soft foundation for use. Due to the complexity of the components of the reinforcement structure, it would be a serious waste to use it by fixing it in the foundation.

[0005] In view of this, it is necessary to develop a soft soil foundation reinforcement structure that can both reinforce the foundation and avoid waste, which is very promising. Utility Model Content

[0024] Please see Figures 1-4 A soft soil foundation reinforcement structure;

[0025] It includes: a reinforcing cylinder 1 and a feeding cylinder 7. The reinforcing cylinder 1 is equipped with a docking assembly, which separates the reinforcing structure. The docking assembly includes a fixing block 5, a positioning groove 6, a mounting plate 12, and a positioning block 13. The fixing block 5 is installed on the bottom inner wall of the reinforcing cylinder 1. The positioning groove 6 is symmetrically opened on the top of the fixing block 5. The feeding cylinder 7 is installed inside the reinforcing cylinder 1. A rotating shaft 11 is installed inside the feeding cylinder 7 and passes through the bottom end of the feeding cylinder 7. The mounting plate 12 is installed at the bottom end of the rotating shaft 11. The positioning blocks 13 are symmetrically installed at the bottom of the mounting plate 12 and correspond to the positioning groove 6.

[0026] The reinforcing cylinder 1 is used to insert into the interior of soft soil foundation to increase the strength and stability of the soft soil foundation. When using this reinforcement structure, it needs to be installed by docking components. First, the feeding cylinder 7 is brought into the rotating shaft 11 and inserted into the interior of the reinforcing cylinder 1. The mounting plate 12 and positioning block 13 installed at the bottom of the rotating shaft 11 coincide with the fixing block 5 and positioning groove 6 on the bottom inner wall of the reinforcing cylinder 1. The mounting plate 12 is located on top of the fixing block 5, and the positioning block 13 enters the positioning groove 6. After the reinforcing cylinder 1 is inserted into the soft soil foundation for reinforcement, the feeding cylinder 7 can be separated from the reinforcing cylinder 1 by pulling it upward, so that the feeding cylinder 7 and the structure installed on the feeding cylinder 7 can be reused for other reinforcing cylinders 1, avoiding waste of materials.

[0027] Please see Figure 1 , Figure 2 and Figure 4 A soft soil foundation reinforcement structure;

[0028] The device includes a reinforcing rod 2 and a rotating shaft 11. Multiple slurry outlets 3 are provided on the outer side of the reinforcing cylinder 1. Multiple reinforcing rods 2 are installed on the outer side of the reinforcing cylinder 1, and the reinforcing rods 2 are located on one side of the slurry outlets 3. A drill bit 4 is installed at the bottom end of the reinforcing cylinder 1. A feed inlet 8 is provided on one side of the feeding cylinder 7. An insertion top plate 9 is installed on the outer side of the top end of the feeding cylinder 7. A bushing 10 is installed inside the top end of the feeding cylinder 7, and the bushing 10 is located on the outer side of the rotating shaft 11. A docking plate 14 is installed at the top end of the rotating shaft 11.

[0029] After the bottom end of the rotating shaft 11 is connected to the reinforcing cylinder 1, the top end of the rotating shaft 11 is connected to the drive structure through the docking plate 14. At this time, the reinforcing cylinder 1 and the reinforcing rod 2 enter the soft soil foundation under pressure. The bottom area of ​​the drill bit 4 is small, which makes it easy for the reinforcing cylinder 1 to be inserted into the soft soil foundation. The feed port 8 provides space for the concrete slurry to enter the feeding cylinder 7. The slurry is discharged into the reinforcing cylinder 1 through the bottom end of the feeding cylinder 7, and finally discharged into the soft soil foundation through the slurry outlet 3. At this time, under the drive of the rotating shaft 11, the reinforcing cylinder 1 drives the outer reinforcing rod 2 to rotate, so that the slurry mixes with the soft soil, which changes the properties of the soft soil and makes the soft soil foundation more stable. After mixing, the reinforcing rod 2 is located inside the soft soil foundation, which further makes the soft soil foundation more stable. Inserting the top plate 9 makes it easy to install and remove the feeding cylinder 7.

[0030] The working principle is as follows: First, the feeding cylinder 7 and the reinforcing cylinder 1 are connected and installed through the docking assembly. Then, it is inserted into the soft soil foundation. Concrete slurry is added into the inside of the feeding cylinder 7 through the inlet 8, and then enters the inside of the reinforcing cylinder 1. Finally, it is discharged through the slurry outlet 3, so that the slurry is mixed with the soft soil foundation, thereby changing the properties of the soft soil foundation and making the soft soil foundation more stable. After mixing, the feeding cylinder 7 is removed and reused.

[0031] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
