摘要

PURPOSE: A pipe unit assembly for a rainwater storage tank is provided to reduce construction cost and period since a prefabricated pip unit is simply assembled and installed in the filed. CONSTITUTION: A pipe unit assembly for a rainwater storage tank comprises a plurality of perforated pipes(10), a connecting sleeve, a cutoff membrane, a triangular member, and a cutoff panel. The perforated pipe comprises a plurality of through holes(10a) for receiving rainwater. The connecting sleeve is formed on one end of a laminated perforated pipe to be connected to another perforated pipe.

The triangular member is formed to fill the gap between the perforated pipes. The cutoff panel prevents rainwater from becoming discharged and supports the perforated pipes.
