After completing the bottom plate of the storage tank, apply the top of the tank and the first circle of the wall, and set up temporarily bloating and fixing beams with the wall board on the lower part of the wall board. Inside the teahouse, the edge of the tank is evenly fabricated to improve the column. Electric gourds are mounted on the column, and the lower end of the electric gourd is linked to the hanging ears on the beam. Then all the electric gourds simultaneously increased the beam, the top and the first circle of the wall to the right height, and the welded welding was the second circle of the wall board. Then the electric gourd is lifted and lifted. Make the low 1 circle of wall boards and the second circle of the wall vertical opposite, and welded formed. Then raise the beam to loosen, reduce it to the lower part of the wall of the second circle and fix it with the wall board. After the welding of the 3rd wall plate is completed, it will be improved and right again. In this process, it is applied to the minimum wall board until the group welding, that is, the manufacturing of the main structure of the storage tank.
