Abstract

The invention discloses a lateral smoke discharging and gas collecting device. The lateral smoke discharging and gas collecting device comprises a gas collecting pipe and a detector set, wherein the gas collecting pipe is arranged in the transverse direction of a tunnel, fixed to the top of the tunnel and connected with a side wall smoke discharging opening of the tunnel; the gas collecting pipe is used for collecting hot smoke and conveying the hot smoke to the side wall smoke discharging opening when a fire disaster occurs; and the detector set is arranged at the top of the tunnel, connected with the gas collecting pipe and used for detecting the hot smoke so as to control opening and closing of the gas collecting pipe. According to the lateral smoke discharging and gas collecting device, the hot smoke with the whole cross section width at the top of the tunnel can be sucked through the gas collecting pipe and conveyed to the side wall smoke discharging opening so as to be discharged out of the tunnel, and thus the problem that in the prior art, a large amount of hot smoke on the side away from the side wall smoke discharging opening cannot be discharged is solved.

Description

technical field [0001] The invention relates to the technical field of tunnel smoke exhaust, in particular to a lateral smoke exhaust and gas collection device. Background technique [0002] In recent years, with the rapid rise of my country's infrastructure, more and more tunnels have been put into construction and use. Because tunnels are generally narrow, long and closed, the internal ventilation capacity is poor; when a fire occurs in the tunnel, the generated hot smoke tends to spread rapidly along the tunnel and is not easy to discharge, which is not conducive to the evacuation of personnel inside the tunnel and fire rescue work development. At present, many experts and scholars have conducted in-depth research on the smoke exhaust method of the tunnel when the fire occurs. [0003] At this stage, there are mainly two types of smoke exhaust methods in tunnels: natural smoke exhaust and mechanical smoke exhaust. Among them, the natural smoke exhaust mainly adopts the...
