When the expansion ring body 210 supported by the supporting member 220 on the inner wall of the storage tank is lifted by the electric chain hoist 330, since the expansion ring body 210 and the wall panel are connected together by several clamping plates 340 on the entire circumference, when the expansion ring body 210 is lifted, the wall panel is also lifted accordingly.

[0069] After the wall panel is lifted, the lower layer of wall panel is assembled. After the lower layer of wall panel and the upper layer of wall panel are welded, the expansion ring body 210 and the clamping plate 340 are moved to the lower layer of wall panel until all the storage tank wall panels are lifted and welded.
