<P>PROBLEM TO BE SOLVED: To provide an assembly rainwater storage tank which stores rainwater collected through a rain gutter or the like so as to effectively utilize it in spraying water on plants in a garden or a planter, for water sprinkling or the like, which is made of wood fitting to the landscape of the garden or streets, of which stock and transport are easy, of which assembling and disassembling are easy, which is relatively low cost and of which maintenance is easy. <P>SOLUTION: A cylindrical barrel part, which is formed of a plurality of strip-shaped side face wood plates connected in a daisy-chain fashion in advance and a polygonal base plate, is tightly bound by an outer band. A waterproof bag is stored inside the cylindrical barrel part. An inner band is inserted so as to form the opening of the waterproof bag and also hold the inner diameter of the cylindrical barrel part. Piping is laid to a piping joint installed in the waterproof bag to introduce and discharge rainwater. The assembly components of the rainwater storage tank are stored and transported in a state that the volumes are reduced by being folded and overlapped each other, and the rainwater storage tank is to be assembled at the time of installing. <P>COPYRIGHT: (C)2012,JPO&INPIT |
