An invention such as No. 3729 was developed. In this construction method, the side walls are manufactured as multiple plate-like long members, making it possible to reduce the amount of formwork and formwork support materials and to shorten the construction period. The structure of the joint joint between each precast panel is such that the inner surface is closed with a sealant and expanded mortar is placed in the notch to create watertightness with the precast panel material due to the expansion action of the mortar. be.
