[0013] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0014] A mixing head for foundation reinforcement of in-situ solidified soil, such as Figure 1 As shown, it includes a connecting column 4 and a first blade 1, a second blade 2 and a third blade 3 fixedly disposed at equal angles at one end of the connecting column 4. The first blade 1 is a bent structure, the second blade 2 is a plate-shaped structure and the third blade 3 is a strip-shaped structure. A plurality of stirring teeth 5 are fixedly disposed on the first blade 1, the second blade 2 and the third blade 3. The other end of the connecting column 4 can be fixed on the rotating shaft 6.

[0015] The aforementioned first blade 1 includes a fixed section 11 and a bent section 12. One end of the fixed section 11 is fixed to the aforementioned connecting post 4, and the other end is fixedly connected to the bent section 12. The stirring teeth 5 are fixedly arranged on the outside of the bent section 12, and the spacing between the stirring teeth 5 is the same.

[0016] The side of the second blade 2 facing the direction of rotation is an inclined section. The width of the second blade 2 gradually decreases along the end away from the connecting column 4. The stirring teeth 5 are fixedly arranged at equal intervals on the side of the second blade 2 facing away from the direction of rotation.

[0017] A plurality of stirring teeth 5 are fixedly arranged at equal intervals along the length direction of the third blade 3 as described above.

[0018] The aforementioned first blade 1, second blade 2, and third blade 3 are fixed to the connecting column 4 by welding. The stirring tooth 5 is welded to the aforementioned first blade 1, second blade 2, and third blade 3. The first blade 1 can squeeze the local part containing boulders to the surrounding area, increasing the reinforcement efficiency. The second blade 2 is plate-shaped, which can increase the overall rigidity of the stirring head. The third blade 3 can work together with the first blade 1 and second blade 2 to reinforce the soft soil in situ.

[0019] It is worth noting that a positioning groove matching the shape of the rotating shaft 6 is provided on the end of the connecting column 4 facing the rotating shaft 6. A fixing groove is also provided on the connecting column 4. The end of the fixing groove is perpendicular to the positioning groove. An external thread is provided in the fixing groove, so that the bolt 7 can be screwed into the fixing groove to fix the connecting column 4 and the rotating shaft 6 as one unit. When disassembly is required, the bolt 7 can be loosened directly, which can achieve quick disassembly and quick replacement.

[0020] The following is a detailed explanation of the foundation reinforcement process for in-situ solidified soil.

[0021] After the mixing head is connected and fixed to the rotating shaft 6 of the mechanical equipment via bolt 7, fly ash is used as a green curing agent. 11% cement and 9% fly ash are added to the soft soil by mass fraction. After mixing with the soft soil using the aforementioned mixing head and mechanical equipment, in-situ curing of large areas of soft soil can be carried out, which can save about 35% of cement while meeting the strength requirements of in-situ cured soil.

[0022] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
