Flue gas layer rate of propagation is detected by the hot-wire anemometer 22 be arranged on around test burning things which may cause a fire disaster 25, this hot-wire anemometer 22 also can be arranged on the upstream and downstream of test burning things which may cause a fire disaster 25, each measuring wind speed tree (it having multiple hot-wire anemometer 22) can arrange at least three test points, to obtain the mean wind speed of this section part, testing result is also sent to sense terminals display by the communications cable and stores.
Flue gas layer form is detected by the laser sheet optical instrument 23 be arranged on around test burning things which may cause a fire disaster 25.Laser sheet optical instrument 23 can be arranged on the upstream and downstream of test burning things which may cause a fire disaster 25, and vertical scale in the middle of integrating tunnel and longitudinal scale of being positioned at the one-sided wall in tunnel carry out data record.Wherein the power of laser sheet optical instrument 23 should be greater than 300 milliwatts, and light source is the green glow of wavelength 532 nanometer.Normal lighting in testing process in closure of a tunnel fire-fighting Performance Detection section, and use video camera to carry out record to the flue gas layer form under laser sheet optical instrument 23 irradiation.
For the fume control system using central exhaust mode, also need to observe smoke evacuation, whether correctly to mend wind pattern, measure the wind speed of smoke vent opening, wind-supplying mouth, and record is along the fire and smoke spread scope of tunnel longitudinal direction.
The radiant heat flux density at test burning things which may cause a fire disaster place is detected by the radiant heat flux densometer 24 be arranged on around test burning things which may cause a fire disaster 25.This radiant heat flux densometer 24 can be arranged on, 5 meters, upstream of test burning things which may cause a fire disaster, and rational height is preferably 2 meters, and is just gathered the direction of test burning things which may cause a fire disaster 25 by sensor.
By directly observing, recording the start-up time of the evacuating personnel guidance system obtaining tunnel fire-fighting Performance Detection section, as emergency lighting start-up time, fire broadcast start-up time, Evacuation Indicatory Sign start-up time, and with the interlock situation of fire detection alarm system, fume control system.
By directly observing, recording the start-up time obtaining automatic fire extinguishing system, the duration, with interlock situation and the extinguishing effect of fire detection alarm system, fume control system.
When tap water will be adopted during as put out a fire to operate, all can adopt waterproofing work, so that fire-extinguishing operations is on the reusable impact of said apparatus to above-mentioned thermocouple tree 21, hot-wire anemometer 22, laser sheet optical instrument 23 and radiant heat flux densometer 24.Forward step S103 to subsequently.
In step s 103, trigger test burning things which may cause a fire disaster, and collect the fire-fighting performance parameter of fire detection alarm system, fume control system, evacuating personnel guidance system and automatic fire extinguishing system.Wherein the fire-fighting performance parameter of detection detecting and warning system, fume control system, evacuating personnel guidance system and automatic fire extinguishing system comprises alert locations and the time of fire alarming of fire detection alarm system, the flue gas layer form that fume control system is corresponding, smoke layer temperature, smoke layer height, fire and smoke spread speed and test burning things which may cause a fire disaster 25 place radiant heat flux density, the start-up time of evacuating personnel guidance system, and the start-up time of automatic fire extinguishing system and duration etc.Forward step S104 to subsequently.
