The traditional construction method of mixing stations meets the needs of building construction to some extent, but also faces many challenges. For example, as the scale of construction continues to expand and the speed of construction accelerates, some drawbacks of the traditional construction method of mixing stations gradually appear, affecting the progress and quality of the entire construction project. At the same time, the increasing awareness of environmental protection also prompts the industry to seek more green and efficient construction solutions for mixing stations.

[0003] Currently, to solve the problem of mixing station silo construction, the following methods are commonly used. One is to cast concrete structures on site, which requires setting up forms on the construction site, then pouring and curing concrete. Another is to use brick masonry structures to build silo partition walls and other structures by stacking bricks. However, both of these methods have long construction periods and are not easy to disassemble, so there is also a prefabricated mixing station that uses steel plate supports to splice.

[0004] However, the prefabricated mixing station in the related art has low splicing accuracy between steel plate supports, which not only easily causes quality problems after splicing, but also increases the difficulty of installing adjacent steel plates, affecting construction efficiency.

The first foundation 1 is arranged at the installation site, and the upper end thereof is located below the ground 100 of the installation site, and the lower end thereof extends downward away from the ground 100. This arrangement can increase the contact area between the foundation and the ground 100 and improve the stability. Alternatively, the first foundation 1 can also be made of reinforced concrete prefabricated parts.

After the limiting plate 5221 is matched with the first groove 421, the limiting plate 5221 is flush with the outer side surface of the positioning portion 42.

[0047] As shown in Figure 1 , Figure 4 and Figure 7 , the positioning member 52 is arranged on the connecting member 51, and the two can be assembled and connected or can be connected in other matching modes, and the specific matching mode is not limited.
