[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-4 A cement mixing pile enclosure structure for reinforcing a soft soil foundation comprises a mixing pile body 1, a bottom plate 2 is arranged outside the mixing pile body 1, and a fixed enclosure device 3 is arranged outside the bottom plate 2;

[0022] The fixed enclosure device 3 includes a fixed cylinder 301, a first threaded rod 302, a mounting sleeve 303, a support plate 304, a second threaded rod 305, a mounting block 306, an electric slide rail 307 and a enclosure plate 308. The bottom of the base plate 2 is fixedly installed with the fixed cylinder 301, the bottom of the base plate 2 is rotatably connected with the first threaded rod 302, the interior of the fixed cylinder 301 is fixedly installed with the mounting sleeve 303, the top of the base plate 2 is fixedly installed with the support plate 304, the interior of the support plate 304 is rotatably connected with the second threaded rod 305, the exterior of the second threaded rod 305 is rotatably connected with the mounting block 306, the interior of the mounting block 306 is fixedly installed with the electric slide rail 307, and the exterior of the mounting block 306 is hinged with the enclosure plate 308.

[0023] Specifically, Figure 4 As shown, when the fixed tube 301 enters the ground, the first threaded rod 302 is rotated, and the first threaded rod 302 moves downward along the inside of the threaded sleeve. The movement of the first threaded rod 302 drives the top block to move downward, and the friction is reduced by the set ball. Then, the slider and the slider are moved outward through the top block. During the process, the slider squeezes the spring body and sends the cone rod out of the fixed tube 301, thereby increasing the contact area of ​​the device with the soil and increasing the stability of the device.

[0024] Specifically, Figure 2 As shown, rotating the second threaded rod 305 can drive the mounting block 306 to move toward the side close to the mixing pile body 1. During the process, the limit rod will also move in the support plate 304. The purpose of setting the limit rod is to increase the stability of the mounting block 306 during movement and maintain a horizontal state. Then the moving directions of the eight electric slide rails 307 are relative. When the mounting block 306 is close to the mixing pile body 1, the electric slide rail 307 is opened to cooperate with the hinged rod to adjust the angle of the enclosure plate 308, and move it closer to the mixing pile body 1, and cooperate with the rubber block to achieve the purpose of enclosure.

[0025] Specifically, Figure 4 As shown, when the device is used up, the electric slide rail 307 can be controlled to move in the reverse direction to retract the enclosure plate 308, and then the second threaded rod 305 can be rotated in the reverse direction to move the mounting block 306 away from the mixing pile body 1, and then the first threaded rod 302 can be rotated in the reverse direction to control the first threaded rod 302 to move upward, and then the slider will move inward under the action of the spring body, thereby driving the conical rod to be retracted into the interior of the fixed cylinder 301, and then the bottom plate 2 can be lifted to retract the device.

[0026] When implementing, follow these steps:

[0027] 1) First, place the device on both sides of the mixing pile body 1, insert the fixing tube 301 into the ground, and then rotate the first threaded rod 302 to move it;

[0028] 2) Then, the first threaded rod 302 moves to drive the top block to move downward to cooperate with the ball bearing, push the slide bar and the slider outward, and squeeze the spring body, so as to send the cone rod out of the fixed cylinder 301;

[0029] 3) Rotate the second threaded rod 305 to move the mounting block 306 toward the side close to the mixing pile body 1 and make it close;

[0030] 4) Finally, open the electric slide rail 307 and cooperate with the hinge rod to adjust the angle of the enclosure plate 308, so that the enclosure plate 308 and the rubber plate fit the outside of the mixing pile body 1 to achieve the purpose of enclosure.

[0031] To sum up, the cement mixing pile enclosure structure for reinforcing soft soil foundation places the devices on both sides of the mixing pile body 1, inserts the fixed cylinder 301 into the ground, rotates the first threaded rod 302 to move downward, and through the movement of the first threaded rod 302, cooperates with the top block and the ball to push the slide rod outward, thereby driving the slider to move and squeeze the spring body to push the cone rod out of the fixed cylinder 301, and then rotates the second threaded rod 305 to drive the mounting block 306 to fit with the mixing pile body 1, starts the electric slide rail 307 and cooperates with the articulated rod to drive the enclosure plate 308 to fit with the mixing pile body 1, so as to achieve the purpose of enclosure, thereby facilitating the fixation of the device and facilitating the enclosure of mixing piles of different sizes.
