PURPOSE: A rainwater storage block is provided to securely couple unit blocks by installing an upper plate which connects two or more adjacent bodies. CONSTITUTION: A rainwater storage block(100) comprises a body(120) and an upper plate(110). Multiple unit cells with inner spaces are arranged in the body. The upper plate is installed on the top surface of the body. Inlets(130), corresponding to the unit cells, are formed in the upper plate in order to flow rainwater into the inner spaces of the unit cells. The body has outlets(140), connection units, and coupling units. The outlets are formed in the bottom of each unit cell and discharge rainwater. The connection unit connects the unit cells so that the inner spaces of the unit cells can uniformly accept the rainwater. |
