Description

The skyscraper rescue system

Technical field

The present invention relates to a kind of when the unexpected stormses such as breaking out of fire, the rescue system that can in time escape in time fire extinguishing of high-rise and personnel.

Background technology

After inflammable, the flammable construction material of a large amount of use of present China part external wall of high-rise building, the form that fire development spreads routine different from the past, present by new feature outer and interior, from high to low, thereby increased the difficulty that fire brigade is puted out a fire to save life and property fire of high-rise building.Fire from Beijing CCTV annex, Shanghai high-rise residential are several, be external wall and install and used a large amount of inflammable, flammable construction materials, as: the polyurethane foam that insulating layer of external wall of building uses, fire externally cause rear rapidly upwards or to building interior, spread expansion, even from roof, spread (Beijing CCTV fire just belongs to this type of) downwards, thereby cause whole building that stereo burning occurs.In addition, outdoor fire general without obvious developing stage minute,, because oxygen supply is sufficient, just can develop into fierce combustion phases very soon after outdoor fire occurs.Development has decisive influence to wind to the intensity of a fire, especially the impact of fire in the open wind-engaging is larger, and the external wall of high-rise building fire is subjected to the impact of wind-force especially, and wind brings a large amount of fresh airs to combustion zone, external wall of high-rise building is wrapped in inflammable, combustible material in a large number in addition, impels burning more fierce.Along with the change of wind direction, the fire spreading direction can corresponding change.Strong wind weather very easily forms jump fire, enlarges rapidly combustion range.Above factor causes fire of high-rise building to cause the shortening of calamity time, and hazard scope and harmfulness further enlarge, and says that objectively reaction time, the disposing capacity to fire brigade also had higher requirement.The way of fire extinguishing commonly used has when breaking out of fire:

A: fire-fighting equipment participates in the high-rise fire rescue

At present the highest motor ladder in the whole world is 101 meters, and maximum jetting height is 150 meters, but tight Ke's condition restriction the performance of its function, wind speed needs lower than 12.5 meter per seconds, the chassis of 101 meters motor ladders is very short, is not suitable for ramp and potted road surface.In addition, the motor ladder volume is huger, and the corner of part residential quarter also can't pass through.In actual fire fighting and rescue process, not having these situations of favourable climate and geographical position and support of the people occurs, even motor ladder is ascended a height smoothly, but only have a hydraulic giant and big fire fight, equal to water in big fire with the hydraulic giant that child plays, so without Ji, the water from peripheral high building to this building injection is because of the not enough fire extinguishing of strength poor effect; Also have motor ladder, in the moment of water outlet, one reaction force is arranged, be easy to occur working bucket, terraced arm because the current reaction force seriously rocks, cause personnel and vehicle dangerous.

B: helicopter participates in the high-rise fire rescue

When fire of high-rise building occurs, the smog interference that a large amount of fire hazard thermal air-flows that rise and burning generate etc. is unfavorable for helicopter near fire building, and the attached structure of various building, as facilities such as billboards, not only hinder the disaster relief, also may cause the helicopter accident that meets accident.In addition, if can't appropriateness smash the glass of building exterior wall, helicopter is got involved fire and is rescued and will be restricted, even if the relaying water supply problem can solve, but because of the restriction of distance with space, the loss of secondary disaster also is difficult to expect.

C: the fireman ascends a height and participates in the high-rise fire rescue

, to the ascend a height presentation of results of test of fire-fighting, when ascend operation, to fireman's heart rate, breathe and have a direct impact, easily cause the panic meaning of psychology disorderly according to professional institution.The physical endurance that surpasses the people along with the increase of climbing height, the people will produce anxiety and weary mood psychologically, the action scope of activities that suppresses the people, lose fight capability, the general fireman 11 floor rooms of ascending a height, average heart rate is 178n/min, the average breathing as 46.8n/min, there is 80% popular rate to surpass or near set upper limit numerical value (180n/min), 100% people breathes and surpasses required standard (40n/min).Due to fireman heart rate and tachypnea in the process of ascending a height, can cause bad psychoreaction, directly affect fireman's combat action.The fireman a complete set of fighting uniform, portable two branch lines or mains water band, bear air respiratorresuscitator arrives 10 layers, 20 layers and has arrived the limit, still more high-storey more.
