The utility model discloses a tunnel fire-fighting system with pavement water and tunnel gushed water as water sources. The system comprises a drainage ditch, a longitudinal drainage and seepage ditch, a side ditch, a transverse drainage pipe, a pavement surface jet stream trough, a water quality sensor, a switching mechanism, a water filtering pond, a sand sediment well, a low water pond, a sewage pond, a pump room, a high water pond and a tunnel fire hydrant, wherein the water filtering pond, the sand sediment well, the low water pond, the sewage pond the pump room, the high water pond and the tunnel fire hydrant are arranged near a tunnel. The pavement water and the tunnel gushed water serve as the water sources, the water sources are more sufficient, water can be obtained conveniently, and cost is reduced. The low water pond, the pump room and the high water pond are arranged so that water pressure can be automatically provided for the tunnel fire hydrant. The water quality sensor is arranged to judge whether the water sources are polluted and controls the switching mechanism to communicate a water inlet to the pump room or the sewage pond, and accordingly corrosion caused by pollution sources on the tunnel fire hydrant and a connection pipeline is avoided.
