Description

Technical Field

[0001] The invention relates to the technical field of solidified soil preparation, and in particular to a preparation process of fluidized solidified filling soil. Background Art

[0002] Fluidized solidified soil is a reinforcement material with certain fluidity, which is made by mixing various discarded base soils, solidifying agents and water in a certain ratio through original technology and special machinery. It has the characteristics of self-leveling and self-compacting, and its general strength can reach 0.5-10MPa. Since the soil itself does not have fluidity, a certain proportion of solidifying agent will be added to the solidified soil used for foundation trench backfill. After the solidifying agent is mixed with the soil, a series of physical and chemical changes will change the soil properties, making it have corresponding fluidity and strength.

[0003] In the process of preparing the existing fluidized solidified filling soil, it is inevitable that the mixed slurry cannot fill the entire preparation device. However, in order to improve the mixing efficiency, the existing preparation device usually adopts an inclined tank for stirring. However, when the mixed slurry cannot fill the preparation device, the mixed slurry will form an inclined surface along the bottom of the tank, which will cause the mixed slurry to be deeper in some areas and shallower in other areas. If the stirring structure is located in a shallower part of the liquid, the slurry cannot be effectively grasped and mixed.

[0004] Therefore, when the above-mentioned preparation device is in use, it is inevitable that the mixed slurry cannot be filled, which makes it difficult for the stirring structure to effectively grab and mix the slurry when it is located at a shallow liquid level, thereby affecting the working efficiency of the entire preparation device.

[0005] In order to overcome the problem that the existing preparation device is often unable to fill the preparation device due to insufficient mixed slurry during use, resulting in the stirring structure being unable to effectively grab and mix the slurry at a shallow liquid level, which can easily affect the working efficiency of the entire preparation device.
