The invention discloses a tunnel fire system with water sources which are slope surface flowing water and road surface water. The tunnel fire system has the advantages that the slope surface flowing water is used as the water source, so that sufficient water storage of reservoirs can be guaranteed, and the cost can be reduced; an intercepting drainage ditch is built on a plurality of contour lines of slopes for collecting rainwater on slope surfaces, so that the water sources can be conveniently acquired, and the tunnel fire system is low in cost; the road surface water is used as the water source for supplementing the slope surface flowing water, and accordingly the water sources are sufficient; the slope surface flowing water in the intercepting drainage ditch is gathered by a constructed rapid flow groove, an included angle is formed between the rapid flow groove and the intercepting drainage ditch, and the water speed can be reduced by the rapid flow groove; an energy dissipation dam is arranged between the rapid flow groove and a filter pond, so that the water speed further can be reduced, and the filter pond can be protected; a water quality sensor is matched with a switching mechanism, waste water can be drained to a waste water pond when the quality of the waste water is disqualified, qualified water can be drained to a high pond, and accordingly a fire hydrant and pipelines can be prevented from being corroded by acidic materials in the waste water; the tunnel fire system is provided with a low-position pond, a pump house and a high-position pond, and accordingly water pressures can be automatically generated for the tunnel fire hydrant.
