Description

Technical Field

[0001] The utility model relates to the technical field of solidified soil mixing, in particular to a solidified soil on-site mixing device. Background Art

[0002] Solidified soil refers to a technology that treats soil by adding specific chemical agents or physical methods to improve the engineering properties and stability of soil. Solidified soil is widely used in engineering fields such as soil reinforcement, contaminated soil treatment, roadbed construction, and foundation treatment. Solidified soil refers to an engineering material that changes the physical and chemical properties of soil by adding a curing agent to improve the strength, stability, and durability of soil. The basic principle of solidified soil is to form a new cementing material or filler through the reaction of the curing agent with the particles and cementing materials in the soil, thereby improving the engineering properties of the soil. Solidified soil can increase the strength and stability of the soil and is used to strengthen soft soil foundations, fill reinforcement, and prevent foundation settlement. Solidified soil can react chemically with pollutants and solidify them in the soil. It is used to treat soil containing pollutants such as heavy metals and organic matter. Solidified soil can improve the bearing capacity and deformation resistance of the roadbed and is used in the construction of roadbeds such as highways and railways.

[0003] The Chinese patent with publication number CN218857316U discloses a solidified soil on-site mixing device, which includes a shell, a circular through hole is provided at the top of one side of the shell and the bottom of the other side, and the shell is rotatably connected to a second rotating shaft and a first rotating shaft at the two circular through holes, respectively, and the second rotating shaft and the first rotating shaft are fixedly connected to a stirring rod at one end inside the shell, and fixed piles are fixedly connected to both sides of the bottom end of the shell, and a circular opening is provided at the bottom end of the main body of the two fixed piles, and the two fixed piles are rotatably connected to the same rotating rod at the two circular openings. The patent can make the flow of the mixture of soil, curing agent and water inside the shell more chaotic by the asynchronous rotation of the two stirring rods, so that a more sufficient and uniform mixing effect can be achieved in a shorter time, so that the mixing efficiency of the device for solidified soil is higher, and naturally it can also facilitate the subsequent use of the solidified soil.

[0004] Based on the above search and combined with the prior art, we found that:

[0005] The existing device can rotate at opposite and different speeds through two stirring rods. In this case, the asynchronous rotation of the two can make the flow of the mixture of soil, curing agent and water inside the shell more chaotic, so that a more sufficient and uniform stirring effect can be achieved in a shorter time. However, the curing agent contained in the solidified soil is different from the particles and binder materials in the soil, and the heavier material will precipitate during the mixing process. The existing device cannot mix the material settled at the bottom, resulting in incomplete mixing, which has limitations in actual use. Utility Model Content
