TECHNICAL FIELD
[0001] The utility model relates to the technical field of fluidized solidified soil stirring equipment, especially relates to a relay stirring and steady flow device for fluidized solidified soil forming. BACKGROUND
[0002] Fluidized solidified soil is formed by mixing solidified agent and water into soil in a certain proportion, and has flowability in a short time and certain strength and impermeability after a certain time. Fluidized solidified soil has been widely used to replace lime soil and plain soil for foundation reinforcement, pit backfilling, temporary site construction and the like due to convenient construction, superior filling effect, controllable performance development, stable solidification effect and significant solid waste storage capacity. However, it is difficult to control the performance of fluidized solidified soil. This is because the main material of fluidized solidified soil is soil, and the amount of solidified agent used for solidification is very small, usually less than 10% of the mass of the soil. The soil has high water absorption and inter-particle adhesion, which causes the soil to easily aggregate, thereby weakening the solidification effect of the solidified agent. At the same time, impurities, particle morphology and water content in the soil and other factors also affect the uniform distribution and reaction effect of the solidified agent, thereby reducing the effect of the solidified agent. In addition, the existing stirring equipment is a large stirring device, the rotating speed of which is low and the shearing force of which is weak, so it is difficult to break up the soil and effectively mix the materials. Moreover, in order to improve the construction speed, the stirring time of the existing fluidized solidified soil is short. Ultimately, the forming quality of fluidized solidified soil fluctuates, which affects the engineering quality.
