20世纪初以来, 由于其耐用性, 各种钢板仓已广泛应用于粮食行业. 虽然它们是坚固的钢结构, 如果使用和维护不当，它们会失去强度并最终损坏.

使用不当和维护不当是造成钢板仓毁坏的主要原因. 定期检查钢板仓并采用正确的进出技术可延长数年的使用寿命.

钢粮仓为薄壳结构. 保持其形状和结构, its sidewalls must be evenly loaded. In view of the fact that the side walls and bottom of the steel silo carry loads of tons of stored grain, the silo foundation must be properly designed and maintained.

1Regular maintenance inspection

For regular maintenance and inspection of steel silo, the basic parts should be checked first.

The foundation must be strong enough to support the stored grain load and prevent the empty silo from dumping or tearing by the wind. Therefore, the storage base must not show symptoms such as uneven settlement, large cracks (Figure 1), broken concrete, failure or looseness of anchor bolts. There should be a waterproof seal between the bottom surface of the warehouse body and the foundation.

Regular maintenance and inspection of steel silo should also include checking whether the silo body shows abnormal conditions such as stiffening bar bending, steel plate bulging, bolt looseness and overall abnormal shape. Sometimes it is even found that the warehouse body is tilted.

Figure 1 Such cracks in the steel silo foundation must reduce the steel silo to support grain storage Load capacity is easy to cause wind damage when the warehouse is empty.

If these symptoms occur, it must be determined whether the steel silo structure is strong. It should be pointed out that some steel plates, especially some steel plates in the middle of the warehouse body, show mild bulging, which is a normal working condition. However, excessive bulging is a sign that the corrugated steel sheet is about to be destroyed by abnormal wrinkles. (Figure 2)
