SMART GRIFT CHAMBER STRUCTURE FOR RAIN USINS SYSTEM

摘要

PURPOSE: A system for rainwater using a smart grit chamber is provided to prevent pollution caused by initial rainwater by separately discharging the initial rainwater in which foreign materials are contained. CONSTITUTION: A system for rainwater using a smart grit chamber comprises a grit chamber(10), multiple rainwater inflow pipes(11), a rainwater outflow pipe(12), a sludge drain pipe(13), an initial rainwater disposal housing(20), an initial rainwater discharge pipe(21), and a closing plate(22). The grit chamber filters soil or sand contained in the rainwater. The rainwater inflow pipes guide the rainwater flowing through the ground surface. The rainwater outflow pipe outflows the filtered rainwater to a drain pipe or a rainwater storage facility. The sludge drain pipe discharges the sludge precipitated in the floor. The initial rainwater disposal housing removes a pollutant contained in the initial rainwater flowing through the rainwater outflow pipe. The initial rainwater discharge pipe discharges the stored initial rainwater to the sludge drain pipe. The closing plate selectively closes an entrance of the sludge drain pipe.
