Embodiment Construction
[0028] The present invention will be further described below in conjunction with accompanying drawing.
[0029] see figure 1 , as can be seen from the figure, the double-chimney tunnel of the present invention is combined with the superstructure natural ventilation system, and a tunnel shaft 3 communicating with the ground is provided at the top of the tunnel 9, and a vertical shaft communicating with the tunnel shaft is provided at the upper end of the tunnel shaft 3. Structural Tunnel Solar Chimney 2. An air inlet 10 and an air outlet 11 are provided on the ground building 8 (that is, the superstructure). The air outlet 11 is higher than the air inlet 10. The air inlet and the air outlet are located on the opposite wall of the superstructure. The horizontal air channel 4 communicates with the ground building solar chimney 1 of the vertical structure, and the bottom of the ground building solar chimney 1 is provided with a load-bearing column 6 . The load-bearing column is...

The invention discloses a double-chimney type tunnel and surface structure joint natural ventilation system. A tunnel shaft is provided with a tunnel solar chimney; a surface structure is provided with an air inlet and an air outlet, the air outlet is communicated with the surface structure solar chimney through a horizontal air flue, and the tunnel solar chimney is communicated with the surface structure solar chimney through a horizontal interconnecting air flue; and fire valves are respectively arranged in the tunnel solar chimney and the surface structure solar chimney, and the two fire valves are both positioned under the horizontal interconnecting air flue. Heat storage devices are respectively arranged in the tunnel solar chimney and the surface structure solar chimney. Airflows of the two chimneys are parallel to double heat pressure, which is more conductive to the mutual complementation and promotion of the ventilation capacities of the two chimneys. The fire valves can prevent the influence of the air party on another party, and the smoke evacuation capacity of the fire party is enhanced.
Description
technical field [0001] The invention belongs to the field of HVAC and building energy saving, in particular to a natural ventilation system combined with a double-chimney tunnel and a superstructure building, and belongs to the technical field of building ventilation. Background technique [0002] Tunnels are long and narrow underground spaces dug by people for the development of transportation. In recent years, with the rapid development of China's economy and the acceleration of urbanization, my country has paid more and more attention to the construction of various traffic tunnels. In 2008, the total length of my country's highway tunnels reached 3,190 kilometers. The total length of railway tunnels in my country has exceeded 7,000 kilometers in 2010, ranking first in the world. In mountainous cities such as Chongqing and Hong Kong, urban highway tunnels have also become important traffic arteries. In recent years, the subway, as another form of tunnel, has flourished ...
