Embodiment Construction

[0064] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0065] Such as figure 1 , 2 As shown, a system for fully enclosed barrier fire extinguishing of a highway tunnel fire includes a highway tunnel wall surface, a slide rail and a fire-blocking module; the fire-blocking module includes a movable fireproof roller shutter and a movable water curtain wall sprinkler group.

[0066] The slide rail is installed on the top of the road tunnel, about 1m away from the top, so as to avoid affecting the operation of the fan;

[0067] The mobile fire shutter is used to isolate the fire area during the fire period to form a closed area; according to the length of the tunnel, a plurality of mobile fire shutters are set in the tunnel, and the shutters are respectively stretched in two directions up and down to realize the safety of the tunnel. fully enclosed.

[0068] The mobile water curtain wall sprinkle...

Abstract

The invention relates to a totally-enclosing and isolating type fire extinguishing method for extinguishing fire in a highway tunnel, and belongs to the field of fire protection. The method comprisesthe following steps: S1, rapidly starting a fire detection module in case of fire in the highway tunnel; and rapidly and accurately determining the special firing position in the tunnel through a firedetection device; S2, rapidly moving fire stopping modules to the fire area after the accurate firing position is obtained; S3, starting and stretching fireproof rolling doors in the fire stopping modules after arriving at the firing area; blocking and closing a combustion area from two ends; and starting spraying through water curtain nozzles on the fireproof rolling doors; an S4, sensing and measuring temperature and smoke concentration in real time through a temperature and smoke concentration sensor in the fire detection module on the top part of the tunnel after two ends are closed and isolated; sending the sensed data back to a control center; and comparing and analyzing. The method is a highway tunnel fire treatment method and is low in cost, high in efficiency, safe and reliable.

Description

technical field [0001] The invention belongs to the field of fire protection, and relates to a method for fully enclosed barrier fire extinguishing in road tunnel fires. Background technique [0002] Highway tunnel fires have a high incidence rate and are highly harmful. Once they occur, they are likely to cause large-scale public safety accidents with mass casualties, especially for long-distance and extra-long-distance highway tunnels, and the impact is extremely bad. [0003] At present, the prevention and control technologies for road tunnel fires mainly include remote monitoring, alarm, jet fan smoke exhaust, shaft smoke exhaust, firefighters entering the tunnel to implement fire extinguishing, etc. For some road tunnel fires with short distances and timely fire detection, the above method has a good effect, and the fire can be extinguished at the first time without causing casualties and major property losses; Due to these reasons, the fire cannot be effectively monit...
