のである。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a method for constructing a lining tank, and more specifically to spent fuel storage pools, reactor wells, and dryer separator storage in nuclear power plants and nuclear fuel reprocessing facilities. This invention relates to a method of constructing a metal plate lined tank in a swimming pool or the like.

を打設する構築方法が採られるようになった。In the case of this conventional technology, it is necessary to wait for the concrete to cure before welding the lining plate, which not only reduces work efficiency in the process, but also makes it difficult to weld because the welding work environment at the site where the lining tank is installed is poor. It was inefficient, caused process delays, and had certain limits on quality improvement. Therefore, as shown in Fig. 2, a large number of prefabricated panels are manufactured by welding shaped steel to the lining plate 4 in advance at the factory, and a large number of them are successively welded at the installation site of the lining tank and assembled into the lining tank. , then concrete 6
The construction method of pouring concrete into concrete began to be adopted.

やや向上するものの、ライニング槽の設置現場では。According to the conventional technology shown in Fig. 2 above, the lining plate of the lining tank can be assembled before concrete pouring, and the work efficiency in the process is improved compared to the technology shown in Fig. 1. Since a large number of prefabricated panels are manufactured by welding shaped steel to the lining tank, the number of welding steps at the lining tank installation site is reduced, and in this sense, the work efficiency in the process is slightly improved, but at the lining tank installation site.

施可能とし。[Objective] Therefore, the object of the present invention is to eliminate the welding work at the installation site of the lining tank, that is, to not only weld the lining plate and the shaped steel, but also to weld a large number of prefabricated panels that have been made into a box shape. The welding work when forming the lining tank can also be carried out at an assembly location other than the lining tank installation site.

ことを特徴とするライニング槽の構築方法である。[Nine measures for solving the problems] In order to achieve the above object, the present invention has the following technical means. That is, the present invention manufactures a prefabricated panel by welding shaped steel to a metal lining plate at appropriate intervals, then assembles a plurality of the prefabricated panels to form the wall surface of a lining tank, and then pours concrete into the lining. In the tank construction method: A plurality of the above-mentioned prefabricated panels of a size that can be transported are assembled in advance at the assembly site, and the connecting parts of each prefabricated panel are welded to create an integral wall surface of the lining tank that is connected in a box shape. The lining is characterized in that the box-shaped integral wall surface is then lifted and installed at a predetermined location, and then concrete is poured around the outer periphery to produce a large metal plate lined tank. This is a method of constructing a tank.
次に添付図面に従い本発明の好適な実施例を詳述する。 Next, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.
先ず、第３図に示すように運搬可能な大きさに分割した
ライニング板７に型鋼８を適宜の間隔で溶接してプレハ
ブパネル９を製作する。First, as shown in FIG. 3, a prefabricated panel 9 is manufactured by welding shaped steel 8 at appropriate intervals to a lining plate 7 that has been divided into transportable sizes.
これは従来通り工場で行なう。This is done in the factory as usual.
次いでこれを現地の作業場所（ライニング槽の設置場所

。After this, at the assembly location under the crane (not the installation location of the lining tank itself, I, 1.), as shown in Fig. 5, the wall surface 11 of the lining tank is assembled into one piece by welding the box shape. , and a lifting framework 12 as shown in FIG.
It is lifted up by a crane and installed in a predetermined position using a crane to form the wall lining of the lining tank at once.

なくなるものである。As detailed above, according to the present invention, it is possible not only to weld a shaped steel to a lining plate, but also to connect a large number of prefabricated panels made of these prefabricated panels to each other to form a box-shaped integrally lined tank wall. This is done at a location other than the installation site of the lining tank, and since this assembly site is large and has a good working environment, welding work can be carried out efficiently and also leads to quality improvement. It is installed as a single piece at the installation location, and no welding work is done at the installation location of the lining tank.
Since the cause of impediment to work efficiency here is removed, the efficiency of the work process as a whole can be improved, and the quality can be improved. In addition, as mentioned above, since the installation is carried out all at once, the period of interference with the lining tank body and the surrounding civil works is short, which reduces problems in the progress of the process.
