[0002] Soft soil foundations are widely distributed in China and are characterized by high water content, large void ratio, low shear strength, high compressibility, poor permeability, and long settlement stabilization time. When carrying out engineering construction on soft soil foundations, problems such as insufficient foundation bearing capacity and excessive settlement are often faced, and it is necessary to reinforce the soft soil foundation. Then a deep mixer for soft soil foundation reinforcement treatment is required. The deep mixer is a special mechanical equipment for reinforcing soft soil foundations by the deep mixing method. Through the mixing blades of the deep mixer, soft clay and the input cement slurry or cement powder are forcibly mixed in place deep in the foundation, so that the soft clay hardens into cement soil with integrity, water stability, and sufficient strength, forming a composite foundation, thereby improving the bearing capacity of the foundation and reducing foundation settlement.

Each double-headed motor 26 drives its respective round wheel mixing blades 28 to rotate and mix. Specifically, the motor one 20 drives the connecting rod one 21 to rotate. The rotation of the connecting rod one 21 drives the movable shaft plate 22 to rotate. The rotation of the movable shaft plate 22 drives the connecting rod two 23 to rotate. The rotation of the connecting rod two 23 drives the connecting shaft rod 24 to rotate longitudinally.

And the multiple round wheel mixing blades 28 are driven by the corresponding double-headed motor 26 to rotate and mix the soft soil foundation. In this way, the multiple round wheel mixing blades 28 perform small-amplitude longitudinal up and down movements and rotational mixing. And the round wheel mixing blades 28 are driven to rotate by their respective double-headed motors 26. Each double-headed motor 26 drives multiple round wheel mixing blades 28 to rotate. The rotation directions of each double-headed motor 26 are different, and the speed of each double-headed motor 26 can also be adjusted.

Inside the combined stirring installation box one 5, the combined stirring installation box two 6, the combined stirring installation box three 7 and the combined stirring installation box four 8, there are independent motor one 20 and independent double-headed motor 26. Each double-headed motor 26 drives its respective round wheel stirring blades 28 to rotate and stir. Specifically, the motor one 20 drives the connecting rod one 21 to rotate. The rotation of the connecting rod one 21 drives the movable shaft plate 22 to rotate. The rotation of the movable shaft plate 22 drives the connecting rod two 23 to rotate. The rotation of the connecting rod two 23 drives the connecting shaft rod 24 to rotate longitudinally.

In this way, the multiple round wheel stirring blades 28 perform small-amplitude longitudinal up and down movements and rotational stirring. And the round wheel stirring blades 28 are driven to rotate by their respective double-headed motors 26. Each double-headed motor 26 drives multiple round wheel stirring blades 28 to rotate. The rotation directions of each double-headed motor 26 are different, and the speed of each double-headed motor 26 can also be adjusted. In this way, the rotation directions of the multiple round wheel stirring blades 28 in each group are different. Therefore, the deep mixer for soft soil foundation is designed with combined multi-axis guiding stirring, which can use multiple round wheel stirring blades 28 together to increase the stirring speed. Moreover, the stirring directions and speeds are also different, and the stirring range can be enlarged as a whole or for small-area regions.

[0036] The soft soil foundation is stirred by the rotation of the extension seat 42 and the stirring cone rod 45. Specifically, multiple second motors 41 are started simultaneously and have the same rotation direction. The multiple second motors 41 drive the driven through-hole external gear 39 to rotate in the inner cavity 36 at the same time. The rotation of the driven through-hole external gear 39 drives the extension seat 42 and the stirring cone rod 45 to rotate to evenly stir the soft soil foundation. When stirring, there is a curing agent inside the placement groove 30. When the extension seat 42 and the stirring cone rod 45 rotate and vibrate, the curing agent inside the placement groove 30 will fall from the gaps of the petal plates 34. The curing agent will fall from the bottom pad 35 onto the stirred soft soil foundation and be mixed with the soft soil foundation during stirring to make the reinforcement more uniform.
