Embodiment 1

[0036] Example 1: tunnel ventilation structure

[0037] Such as figure 1 As shown, on the upway 11 of the tunnel, the overall movement direction of vehicles such as trains and automobiles or pedestrians is from left to right, so multiple or multiple groups of ejection devices are sequentially arranged on the upway 1, and the ejection devices The ejection direction is also from left to right, which is consistent with the movement direction of vehicles or pedestrians.

[0038] Equally, on the downway 14 of the tunnel, the overall movement direction of vehicles such as trains, automobiles or pedestrians is from left to right, then on this downway 14, a plurality or groups of ejection devices are sequentially set, and the ejection devices The ejection direction is also from left to right, which is consistent with the movement direction of vehicles or pedestrians.

[0039] Of course, as mentioned earlier, in figure 1 An arrow in the figure does not necessarily represent an injec...

Embodiment 2

[0040] Example 2: tunnel ventilation structure

[0041] Such as figure 1 As shown, on the upway 11 of the tunnel, the overall movement direction of vehicles such as trains and automobiles or pedestrians is from left to right, and then multiple or multiple groups of ejection devices are sequentially arranged on the upway 11, and the ejection devices The ejection direction is also from left to right, which is consistent with the movement direction of vehicles or pedestrians.

[0042] Equally, on the downway 14 of the tunnel, the overall motion direction of vehicles such as trains, automobiles or pedestrians is from right to left, then on this downway 14, a plurality or groups of ejecting devices are sequentially set, and the ejecting devices The ejection direction is also from left to right, which is consistent with the movement direction of vehicles or pedestrians.

[0043] Of course, as mentioned earlier, in figure 1 An arrow in the figure does not necessarily represent an ...

Embodiment 3

[0051] Embodiment 3: tunnel ventilation structure

[0052] Such as figure 1 As shown, on the upway 11 of the tunnel, the overall movement direction of vehicles such as trains and automobiles or pedestrians is from left to right, so multiple or multiple groups of ejection devices are sequentially arranged on the upway 1, and the ejection devices The ejection direction is also from left to right, which is consistent with the movement direction of vehicles or pedestrians.

[0053] Equally, on the downway 4 of the tunnel, the overall movement direction of vehicles such as trains, automobiles or pedestrians is from right to left, then on this downway 14, a plurality or groups of ejecting devices are sequentially set, and the ejecting devices The ejection direction is also from left to right, which is consistent with the movement direction of vehicles or pedestrians.

[0054] Of course, as mentioned earlier, in figure 1 An arrow in the figure does not necessarily represent an inj...

Abstract

A ventilation structure and method for a tunnel. The tunnel includes an uplink and a downlink. It is characterized in that an ejection device is arranged in the tunnel, and the ejection device is used to eject air from its inlet end to its outlet end. From the ejection device The direction from the entrance to the exit is the injection direction, which is the same as the direction of vehicles or pedestrians on the uplink or downlink. The injection device forms a ventilation structure in the tunnel to achieve ventilation in the tunnel.

Description

technical field [0001] The invention relates to the technical field of road traffic, such as tunnels and other closed environments with poor natural ventilation, in particular to a tunnel ventilation structure. Background technique [0002] With the development of society, infrastructure construction is in full swing, and the demand for personnel mobility has further led to infrastructure construction. In order to better realize the interconnection between different regions, more railways and roads need to be built. However, due to geographical constraints, in non-plain areas and urban areas, many railways, roads and other passages are not suitable for ground Built on. For example, in mountainous areas, if the road passages are all on the ground, they will be crooked, which reduces the efficiency of interconnection, which needs to be solved through tunnels; for example, in cities, the ground resources are expensive, so sometimes it is more appropriate to build underground p...
