The invention relates to a tunnel ventilation system which comprises a tunnel and a fluidic ventilator arranged outside the tunnel. A cooling box is arranged in the tunnel, the fluidic ventilator is connected with an air inlet of the cooling box through an air feeding belt, an air outlet of the cooling box is connected with an air outgoing belt, multiple ice-storage rebar cage supports are arranged on one side, of the air inlet, in the cooling box, a plate-type ice-storage rebar cage is arranged on each ice-storage rebar cage support along the length direction, the top end of each plate-type ice-storage rebar cage is connected with a top plate of the cooling box, ice blocks are placed in each plate-type ice-storage rebar cage, an air way is formed between each two plate-type ice-storage rebar cages along the longitudinal direction of the tunnel, a limiting frame is arranged on one side, of the air outlet, in the cooling box along the transverse direction of the tunnel, and a condensed fog filtering net is arranged on the limiting frame. By the tunnel ventilation system, the problem of water mist pervading in the tunnel when the ice blocks are utilized to decrease environment temperature in the high-temperature tunnel in a forced manner under the circumstance that temperature of natural environment outside the tunnel is high is solved.
Description
technical field [0001] The invention relates to the technical field of tunnel construction, in particular to a tunnel ventilation system, and more particularly to a tunnel ventilation system capable of forcibly reducing the ambient temperature in a high-temperature tunnel. Background technique [0002] During tunnel construction, the heat of hydration released by the tunnel support and lining concrete, the heat emitted by mechanical operations, and the temperature rise generated by geothermal heat, coupled with the narrow space inside the tunnel, make the temperature inside the tunnel very high. [0003] In order to reduce the temperature in the tunnel and make the construction in the tunnel proceed normally, jet fans are generally used to force natural wind into the tunnel, and exhaust fans are installed in the tunnel as needed to discharge hot air outside the tunnel to form circulating air. , to reduce the temperature in the cave. But in hot summer or when the natural env...
