In the case of a water tank for storing water, a concrete tank mainly made of concrete is mainly used, and recently, a stainless steel tank mainly made of stainless steel is mainly used.

However, recently, a PE tank having a PE material has been proposed due to the rusting due to the chlorine gas of the tap water, but the PE tank is structurally weak and needs to be improved.

In addition, although concrete tanks are used as underground burial tanks to prevent floods at national level, to solve the water shortage problem in drought and to prepare stormwater for the abnormal weather, these concrete tanks are structurally sound It is troublesome to coat the wall with epoxy or the like.

On the other hand, there is a problem that the PE tank is used as a prefabricated structure, but it is structurally complicated. As a substitute technology, new tank making techniques have been disclosed, but most of the techniques are not available in actual use because of lack of practicality.

In addition, conventional methods of manufacturing the water purification apparatus and the prefabricated tanks of the storage tanks are separately manufactured and installed in blocks, cylinders, and squares, and separate jugs are installed in the water purification plant to make it difficult to manage, There has been a problem that the production cost problem is excessive and the loss is large.
