A rainwater and sewage separation and discharge system is provided to drain rainwater by shutting a sewage discharge port with rainwater flowing into a manhole, and to operate the rainwater and sewage separation and discharge system quickly by restricting inflow into the sewage discharge port with an auxiliary block. A manhole(10) includes a rainwater and sewage inlet(23) flowing rainwater and sewage in, a weir(40) dividing the manhole into a sewage discharge range(20) and a rainwater discharge range(30), a sewage discharge port(25) formed in the sewage discharge range, and a rainwater discharge port(35) formed in the rainwater discharge range. A rainwater inlet part(50) is placed in the rainwater discharge range, and composed of a rainwater inlet(51) opened up to flow rainwater over the weir and provided with a drain hole(55) and a rotating bar(52) combined with an upper rear part of the rainwater inlet. A turning shaft(57) is extended and installed at a sidewall of the manhole and connected to the rotating bar to turn the rainwater inlet. A cover(71) is formed to be as large as the sewage discharge port, and a cover part(70) is connected to the rainwater inlet. A restoring part(90) is connected to the rainwater part to restore the rainwater inlet in draining water through the drain hole. |
