[0002] Indoor preparation of foundation soil is a prerequisite for model test research in the field of geotechnical engineering. Field foundation soil generally contains soil particles of different particle sizes, and the relative content of different particle size soil particles is called soil gradation. If the content of different particle size soil particles is uniform and reasonable, it is well-graded soil, otherwise it is poorly-graded soil. Indoor preparation of different gradation soil is very tedious because it needs to prepare soil with different particle sizes and different contents.

[0003] Currently, indoor preparation of foundation soil is usually prepared by using single particle size soil to prepare homogeneous soil, or by taking soil from the field to the indoor oven drying and mixing, then adding water and stirring to prepare foundation soil close to the field gradation. The device used in the mud preparation process is generally a simple stirring box. The amount of soil used is calculated, and then the soil and water are manually added and stirred to prepare the required mud. Finally, the prepared soil is consolidated to prepare the foundation soil.

[0004] The device for preparing soil mud has a single function, usually only has a simple stirring function, and is suitable for stirring a large amount of purchased homogeneous soil with water to prepare homogeneous soil mud, which cannot meet the real demand for preparation of different gradation soil mud. The process of re-distributing the soil after drying in the field is complicated and cannot meet the requirement of mass preparation. If the existing simple mud preparation device is used, the soil with different particle sizes and different contents is manually distributed, then added to the stirring device with water and stirred to prepare the required mud.
