Slag Storage Silo Construction

  1. 1.Choose flat ground as construction platform for slag silo, including the silo's main structure, steel frame, steel column and connection machine.
  2. 2.Set up the forming machine, bending machine and the supporting frame horizontally.
  3. 3.Put the coil into the forming machine.
  4. 4.With the bending machine bending bite into the spiral rib 5 times the thickness of the silo body.
  5. 5.When the silo height reaches 2m, use automatic cutting machine to cut silo body top in horizontal.
  6. 6.Install the silo roof.
  7. 7.Keep constructing the silo body using bending and forming machines to the designed silo height.
  8. 8.According to the drawings of reinforcing ribs, weld them in the inner silo wall. (This step is constructing at the same time of step 8)
  9. 9.Use the cutting machine cut the silo body bottom plate in horizontal.
  10. 10.Reverse rotation silo to silo foundation plate, fall to the embedded steel part.
  11. 11.Connect the reinforcing rib and the embedded part, and complete the rooting work
