PREFABRICATED RAINWATER STORAGE TANK

摘要

PURPOSE: A prefabricated rainwater storage tank is provided to cleanly maintain a water storage space and to partially repair the storage tank by independently closing water storage blocks. CONSTITUTION: A prefabricated rainwater storage tank forms a water storage space by assembling and connecting a plurality of water storage blocks (10). The water storage block includes an inlet (11) and a down-stream circulation hole (12). The down-stream circulation hole is connected to an adjacent water storage block and is opened by a valve (13). The water storage space is expanded or is reduced by selectively using the water storage block. A transfer pipe connected to a pump is installed in each water storage block and independently discharges rainwater.
