Zusammenfassung:PROBLEM TO BE SOLVED: To install a rainwater storage tank without using a large heavy machine and easily construct the rainwater storage tank even if its shape is complicated. SOLUTION: In the rainwater storage tank 1, a weir 5 is installed at the outer periphery of the rainwater storage tank 1 formed on the ground by arranging a plurality of intercepting members 4 side by side, and a waterproof sheet 6 is laid down water-tightly on the ground surface surrounded by the weir 5 and on the inner peripheral surface of the weir 5 so that rainwater can be introduced into and drained from the rainwater storage tank 1 surrounded by the waterproof sheet 6. A load supporting member 9 capable of supporting a cover member 8 is vertically installed on the waterproof sheet 6, and the cover member 8 is installed thereon to shield light incident to the inside thereof.
