Cost effectiveness of steel plate silos

Steel Plate Silo has a light weight, low requirements for the foundation, (on average, half of the construction cycle of reinforced concrete silo), covers an area of small, labor-saving, low-cost and other characteristics, but also can be used double-wall plate will be silo in the body of the outer wall with two different materials processing synthesis of the body, which can reduce the construction cost. At the same time, the steel plate warehouse construction is basically not affected by the season, weather and other factors, the use of enterprises can quickly achieve good economic results. According to actual calculations, compared with the same capacity of reinforced concrete silo, steel plate silo steel consumption and its reinforcing steel consumption is almost equivalent to the amount of cement to save about 2/3; concrete silo because of the weight and height requirements of its high cost of the foundation, the total investment is high, to be higher than 15% to 40%, the cost analysis of the two are shown in Table 3-1.

 

  Assembled Steel Silo warehouse capacity, high degree of mechanical automation, management tends to be scientific, rationalization, network, can effectively reduce operating costs, and local can be disassembled and replaced, easy to operate. For the same silo capacity, concrete silo diameter is small, high height, relatively high height of the grain layer, grain storage management is more difficult (such as difficult ventilation or ventilation is not uniform, can not achieve the effect of ventilation of grain storage; fumigation is difficult, that is, PH3 fumigant is also difficult to penetrate the deeper layer of grain and can not achieve the effect; grain layer of grain quality of each part of the sampling and testing is more difficult, maintenance is difficult, especially after a long time of use, easy to cracks, heat preservation and Especially after a long time of use, it is easy to have cracks, insulation and moisture-proof layer damage and other phenomena, which are difficult to repair and maintenance will be more difficult.
