持して構成されている。As shown in FIGS. 1 to 3, tanks for heavy oil, etc., are made by welding an annular plate 2, which is made up of a plurality of plates welded in an annular shape, to the outer periphery of a bottom plate 1, and supporting this annular plate 2. It is configured.
ところで、前記タンクにおいて、タンクの腐食は側板３
を支持するアニユラ−プレート２の部分に多（生じ、し
たがって。By the way, in the above-mentioned tank, corrosion of the tank occurs on the side plate 3.
The portion of the annular plate 2 that supports the
アニユラ−プレ〜１・２を取替える必要が生ずる。It becomes necessary to replace annual pre-1 and 2.

地盤を補強してタンクの周囲に多数のジヤツキを配置し
、これらジヤツキを前記 板に係合してタンク全体を持
ち−１こげてこれを行っていた。Conventionally, to replace the annular plate, the tank roof plate 5 was cut open and a support member was brought inside, and this support member was fixed between the tank side plate 3 and the pillars 4 and between the pillars 4 to prevent the tank from deforming. -1: L, fix a plate around the outside of the tank side plate 3 near the bottom, reinforce the ground around the tank, arrange a large number of jacks around the tank, and engage these jacks with the plate. He did this by holding the entire tank and burning it by -1.
しかし、前記の方法によると、タンク内部への支持部材
の搬入のためタンク屋根板を切開く必要があり、また、
タンク周囲の地盤の補強を要し、ジヤツキによってタン
クを持ヒげる際。However, according to the above method, it is necessary to cut the tank roof plate in order to carry the support member into the tank, and
When the ground around the tank needs to be reinforced and the tank can be lifted by jacking.
タンクが傾斜しないようにするため、タンク周囲に多く
