SYSTEM OF SPRINKLING RAINWATER IN APPARATUS FOR GREENING ROOFTOP

摘要

PPROBLEM TO BE SOLVED: To solve problems of the need for using tap water, confirming dried conditions of an apparatus 1 for greening the rooftop on the rooftop and operating a water sprinkling facility in sprinkling water on the apparatus 1 for greening the rooftop by a manager and further of the need for applying a fertilizer by manpower or a fertilizer applying facility even for applying the fertilizer and requiring great maintenance cost of the apparatus 1 for greening the rooftop. PSOLUTION: The system of sprinkling rainwater is designed to sufficiently carry out inspection of the apparatus 1 for greening the rooftop by storing rainwater and automatically sprinkling the rainwater and simply throw the fertilizer into a water storage tank 4 for applying the fertilizer and thereby remarkably reduce the maintenance cost. The rainwater can be stored in the water storage tank 4 during heavy rain to thereby perform regulation of flood. When a water storage tank for water for miscellaneous use is installed, the water storage tank can be used even as a water source for water for miscellaneous use. PCOPYRIGHT: (C)2006,JPO&NCIPI
