Different materials can be filled in the filling cavities according to different uses of the silo.

[0008] Furthermore, the load-bearing layer includes a concrete wall, a steel mesh is embedded in the concrete wall, and a plurality of longitudinal reinforcements are annularly arranged in the concrete wall. The strength of the silo wall is improved by the steel mesh and the longitudinal reinforcements.

[0009] Furthermore, the longitudinal reinforcement is vertically arranged in the concrete wall, and the longitudinal reinforcement is tied and fixed to the steel wire mesh.
