Description

Technical Field

[0001] The utility model relates to the technical field of mixing devices, and more specifically to a material mixing device for in-situ solidification of soft soil foundations. Background Art

[0002] The foundation refers to the soil or rock that bears the load of buildings, machinery and equipment. The bearing capacity of the foundation is related to the safety of subsequent construction. Therefore, it is necessary to ensure that the foundation has good bearing capacity. However, not all land is suitable as a base material. For example, soft soil has low mechanical strength, strong compressibility, and poor bearing capacity, which can easily cause building subsidence. Therefore, soft soil needs to be treated before construction. The traditional treatment method is mostly excavation and replacement. The construction team uses an excavator to dig the soft soil out of the site and then replace it with crushed stone in the original position. With the advancement of technology, a new soft soil treatment method has come into our view. This technology, called soft soil in-situ solidification, uses Soil solidifier acts directly on the silt, solidifies the soft soil on site, and forms a composite and stable new base. Compared with the commonly used soft soil that is excavated and then transported out for stacking, the on-site solidification of soft soil realizes the use of local materials and turning waste into treasure. It has the characteristics of convenient construction, short construction period, low cost and stable solidification effect. Soil solidifier is a new type of energy-saving and environmentally friendly engineering material synthesized from a variety of inorganic and organic materials for solidifying various types of soil. For the soil that needs to be reinforced, it is mixed and formulated according to the physical and chemical properties of the soil.

[0003] Insufficient existing technology: the existing mixing device cannot accurately control the amount of various raw materials when stirring the various raw materials of the soil solidifier, which affects the quality of the subsequent finished product; at the same time, uneven mixing is prone to occur during the stirring process.
