More Information
Summary:The invention discloses a low-lying area roof rainwater unpowered drainage system and method, and belongs to the field of municipal drainage. By means of the potential energy advantage of roof rainwater, an independent pressure flow rainwater pipe canal system is newly built, and roof rainwater of a low-lying or limited community is drained into a municipal rainwater trunk canal outside a low-lying area by means of height difference. The system is low in construction difficulty, low in disturbance to surrounding buildings, small in pipeline scale, deep in burying depth, low in excavation difficulty and extremely low in disturbance to surrounding old buildings, and a pump station does not need to be newly built or original pipelines do not need to be updated. According to the system, a traditional rainwater down pipe is combined with a rainwater gas-water separation and pressure regulator, a ground rainwater pressure drainage system is matched, and the purpose of collecting and discharging roof rainwater in th
