Embodiment Construction

[0013] The features of the present invention and other related features will be further described in detail below in conjunction with the accompanying drawings through embodiments, so as to facilitate the understanding of those skilled in the art:

[0014] Such as figure 1 As shown, the labels respectively represent: uplink tunnel 1, downlink tunnel 2, tunnel side wall 3, tunnel side wall 4, air duct: U1, U2, U3, U4, U5, D1, D2, D3, D4, D5.

[0015] Such as figure 1 As shown, the road tunnel is a two-hole one-way road tunnel, including an uplink tunnel 1 and a downlink tunnel 2. In this embodiment, the part extending inward from the exit of the tunnel is called the tunnel exit section. For the uplink tunnel 1 and the downlink tunnel 2, the exit sections are respectively located at both ends of the tunnel.

[0016] In the upward tunnel 1, the tunnel air is affected by the piston action of the vehicle, and flows from the entrance to the exit of the upward tunnel 1. Fresh air f...

Abstract

The invention relates to a mechanical dispersion air-discharge apparatus for road tunnel belonging to the road tunnel ventilation field. a plurality of wind channels are formed on the road tunnel exitsegment in the range with the distance of 10%-30% of the tunnel overall length to the exit; the wind channels are formed on the top or side wall of the road tunnel; a blower fan is disposed in each w ind channel; and the air-discharging amount of the wind channel is no less than 70% of the total ventilation of the tunnel. The invention has the following advantages: solves the problem of centralized air-discharge well construction in road tunnel (especially city tunnel); dispersing the tunnel exhaust to reduce the influence to environment; enriches tunnel exhaust gas exhausting manners, and improves the tunnel construction feasibility of the section difficult for building wind well.

Description

technical field [0001] The invention relates to road tunnel ventilation, in particular to a mechanically dispersed air exhaust device for road tunnels. Background technique [0002] In the road tunnel, the driving vehicles will continuously emit harmful exhaust gas and smoke. When the concentration of harmful exhaust gas and smoke exceeds a certain value, it will bring harm to the drivers and passengers, affecting their health and driving safety. Therefore, in order to ensure the hygienic standard of the air environment required for the normal operation of the tunnel, the tunnel should be ventilated. Because the tunnel concentrates a certain length of automobile exhaust, when there are residents at the tunnel entrance, the tunnel exhaust gas is not allowed to be discharged concentratedly at the tunnel entrance. Therefore, urban tunnels are equipped with centralized waste gas discharge air shafts at the entrance of the cave, so that most of the exhaust gas of the tunnel can ...
