Underwater tunnel ventilation system and ventilation method
The invention discloses an underwater tunnel ventilation system and ventilation method. Two ends of a service tunnel are provided with ventilation shaft exhaust ducts and ventilation shaft air delivery ducts and are connected with the exhaust ducts and the air delivery ducts; each exhaust duct is communicated with one main tunnel via an exhaust connection duct; each air deliver duct is communicated with the other main tunnel by an air delivery connection duct; a replacement ventilation connection duct is arranged between the two main tunnels to communicate the two main ducts; fresh air enters the air delivery duct from the ventilation shaft air delivery ducts on two ends of the service tunnel, and enters one main tunnel via the air delivery connection duct; replacement axial fans are started to cause air flow in one main tunnel to enter the other main tunnel via the replacement ventilation connection duct, and polluted air is discharged from the ventilation shaft exhaust ducts via the exhaust connection duct and the exhaust ducts. According to the ventilation system, the service tunnel is used as an air duct to import fresh air into the tunnel and discharge the polluted air, and the difficulty that an artificial island ventilation shaft needs to be arranged in every multiple kilometres for a part, which passes through a water area, of the tunnel for a long distance is solved.
