Problems solved by technology

Once a fire breaks out on the underground transportation layer, a large amount of smoke will be produced, and it will not be like an open space on the ground. If it is not discharged quickly, it will bring people's lives in danger, and people's personal safety will be threatened.

Embodiment 1

[0028] like Figure 1-Figure 3 As shown, the underground transportation ventilation and smoke exhaust system includes an air duct wall 1, an air shaft 5 and an air shaft pipe 6. On the driving road surface of the underground traffic layer, an air duct wall 1 is arranged, and the upper end of the air duct wall 1 is connected to the air duct wall. Well 5. The air shaft 5 is horizontally arranged in a state parallel to the running road surface of the underground traffic layer. The left and right ends of the air shaft 5 are connected to the concrete shell of the underground traffic layer, and then an oblique air shaft pipeline 6 is arranged to reach directly above the ground. A main fan 4 is arranged in the middle of the air shaft 5 , and a smoke outlet 2 is arranged on the side wall below the air shaft 5 on the left and right sides of the main fan 4 . An auxiliary fan 3 is provided at the connection between the air duct wall 1 and the air shaft 5 , and a smoke outlet 2 is provi...

Embodiment 2

[0033] The outside of the air vent 7 is provided with rainproof shutters. Other structures are with embodiment 1.

Abstract

Underground traffic ventilation and smoke exhaust system, including ventilation ducts, smoke outlets (2), auxiliary fans (3) and vents (7). mouth (2) and auxiliary fan (3), the upper part of the ventilation duct is provided with a vent (7), and the upper part of the vent (7) is provided with an awning (8). The beneficial effects of the present invention are: due to the large traffic volume of the underground traffic and the huge closed space, we set up an auxiliary fan, which sucks the dirty air in the garage and discharges it through the air well and the air well pipes, plus The natural ventilation of the ventilation duct system, the combination of the two can better ventilate the underground traffic, and the power of the auxiliary fan is small, which saves the cost and the usual power consumption.

Description

technical field [0001] The invention relates to an underground traffic ventilation and smoke exhaust system, which belongs to the field of urban underground road engineering and the technical field of municipal facilities. Background technique [0002] At present, urban transportation construction is in full swing. As the country further promotes the strategy of comprehensive pipe corridors and sponge cities, large and medium-sized cities in my country will surely set off a new round of climax in underground engineering construction. Due to the scarcity of underground space, the collection of "urban underground comprehensive pipe corridors" , urban underground expressways, and urban underground building space” are in great demand. [0003] The development and construction of underground space in Japan, Europe and the United States is in a leading position. It was the first to advocate and propose the concept of comprehensive and three-dimensional development of underground ci...
