[0028] Reference Figure 1 and Figure 2As shown, this utility model provides a fluidized solidified soil preparation device, including: a static mixing component 1, a slurry treatment and conveying component 2, a curing agent storage and mixing component 3, and a pumping system; the static mixing component 1 includes a mixing cylinder 11, the mixing cylinder 11 is provided with a mixing chamber 114 and a first inlet 111, a second inlet 112, and a first outlet 113 communicating with the mixing chamber 114; the slurry treatment and conveying component 2 is connected to the first inlet 111 to facilitate conveying slurry into the mixing chamber 114; the curing agent storage and mixing component 3 is connected to the second inlet 112 to facilitate conveying curing agent into the mixing chamber 114, and the slurry and curing agent are mixed in the mixing chamber 114 to form fluidized solidified soil; the pumping system is connected to the first outlet 113 to facilitate conveying the mixed fluidized solidified soil to the construction location.

[0029] Specifically, the mud treatment and conveying assembly is used for the storage and conveying of mud, and the curing agent storage and mixing assembly 3 is used for the storage and conveying of curing agent. By connecting the mud treatment and conveying assembly and the curing agent storage and mixing assembly 3 to the first inlet 111 and the second inlet 112 of the mixing cylinder 11 respectively, the mud and curing agent are conveyed to the mixing chamber 114 for mixing.

The mud conveying pump 22 is adapted to convey the waste mud to the mixing chamber 114.

[0031] Specifically, the mud storage tank 21 is used to store waste mud from the construction site, thereby reducing waste mud transportation, dust emissions, and material waste; at the same time, the waste mud is used to prepare solidified soil, reducing reliance on raw materials and achieving a construction mode that combines energy conservation and environmental friendliness.

[0038] In some embodiments of the present invention, the static mixing assembly 1 further includes a mixer 12, which includes a rotating shaft 121 disposed in the mixing chamber 114 and mixing blades 122 rotating with the rotating shaft 121. The mixing blades 122 are in a continuous spiral shape.

[0039] Specifically, by setting the mixing blades 122 in a continuous spiral shape, the mud and curing agent are sheared and dispersed into multiple liquid columns, thereby improving the uniformity of mixing and ensuring the mixing quality.

[0040] In some embodiments of this utility model, the mixer 12 further includes a drive member 123 disposed on the mixing cylinder 11.

[0042] Specifically, by setting the cutting mechanism 14, the port clamp 141 provides an installation base for the cutting component 142. The setting of the cutting component 142 can disperse the mixed fluid material into multiple liquid columns, which is conducive to the discharge of the mixed fluid from the mixing cylinder 11 and improves the backfilling effect.

[0043] It is understandable that the mixing cylinder 11, the drive component 123 and the cutting mechanism 14 are connected by threads to achieve detachable installation, which facilitates the removal, installation and repair of each component and is not prone to damage to the device; it is suitable for mass production, with low production and maintenance costs, and the device has high working efficiency, strong reliability and good energy-saving effect.

[0044] In some embodiments of this utility model, the monitoring element 131 is inserted through the port clamp 141 and is located at the rear end of the cutting member 142 along the flow direction of the fluidized solidified soil.

[0045] To improve the accuracy of monitoring, since the cutting element 142 achieves further mixing, the monitoring element is placed at the rear end of the cutting element 142.
