Description

[0001] Apparatus for exhausting smoke in subway platform [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention [0002] The present invention relates to a subway platform lift system for evacuating smoke generated by a fire or the like in a subway platform.

Generally, subways are attracting attention as a means of solving traffic congestion, logistics costs, and pollution problems caused by vehicles. As a result, most advanced countries are gradually expanding and promoting the sector under government support, and there is a tendency that the share of traffic is gradually increasing due to the advantages of subway such as rapidity, comfort, safety, .

However, the subway has the characteristic that many citizens use it, and there is a risk that it can cause a lot of life and property damage in the event of a disaster or an accident. Especially, the risk of subway is increasing due to crime such as various terrorism due to unstable international environment and fire to the unspecified number due to social unrest.

For example, as shown in the case of the Daegu subway fire disaster on February 18, 2003, the occurrence of a fire in the subway caused the death of many innocent civilians due to the smoke of toxic gas, There are also problems that cause a lot of losses to our society such as enormous economic and social costs and a disruption of national image.

FIG. 1 is a cross-sectional view schematically illustrating the structure of a conventional subway. As shown in FIG. 1, when a fire occurs in the subway platform 100, a large amount of toxic gas such as toxic gas instantaneously generated by a fire is generated . Most of this smoke is exhausted along the stairway passage 1200 of the subway platform 1100 and the subway waiting room 1110 because the stairway passage 1200 serves as a passage for the chimney.

That is, in the event of a fire, the smoke that is generated instantaneously is concentrated in the direction of smooth exhaust flow. The history of the subway serves as a structure like a large chimney as shown in FIG. 1, and the stairway passage 1200 has a chimney As shown in FIG.

Therefore, when smoke such as toxic gas is generated due to a fire or the like in the subway platform 1100, most of the smoke is exhausted through the stairway passage 1200, which is a fatal cause to kill passengers evacuating through the stairway passage 1200 . In addition, smoke such as toxic gas generated when a fire occurs interferes with a power failure to further darken the field of view in the subway platform 1100, thereby obstructing escape of the passenger evacuating through the stairway passage 1200, Which is a problem of inhibiting.

Meanwhile, a duct 1610 for ventilation is installed in the subway platform 1100 to exhaust the smoke generated by the fire. However, most of the installed capacity of the subway platform 1100 is installed in the subway platform 1100 It has a structural problem that it is not possible to exhaust the smoke due to the occurrence of the fire promptly and sufficiently. Therefore, exhaust through the duct 1610 installed in the subway platform 1100 is extremely small.

The ventilator 1400 is installed at a certain interval in the vehicle passageway 1300 on both sides of the subway platform 1100. The ventilator 1400 is spaced apart from the subway platform 1100 by a certain distance, The smoke generated in the subway platform 1100 can not be efficiently forced to be sucked and exhausted. Therefore, most of the smoke generated in the subway platform 1100 is forced to be discharged through the stairway passage 1200 of the subway platform 1100, which causes the problem that the smoke in the subway platform 1100 can not be quickly discharged It was.

Meanwhile, in order to solve the above-described conventional problems, a ventilation facility such as a large-capacity ventilation facility is installed in the air-conditioning room in the history of the subway and a duct 1610 of a large capacity is installed in the subway platform 1100 There can be a way. However, such a method can be applied to the subway history under construction, but there are structural problems that can not be applied to the subway history that has been completed.

The reason for this is that most subway stations have been designed and built without additional space due to the expansion of these facilities. Therefore, in order to expand the construction of the additional ventilation system, the structure of the subway history must be remodeled. In this process, the structural safety problem of the subway historical building, the excessive construction cost, and the cost of the expensive ventilation equipment are generated, It was not feasible.

As described above, the core of the safety system according to the occurrence of fire in the subway platform 1100 will be determined according to how quickly and efficiently the smoke generated in the fire is discharged. In the past, however, Due to the problems of the structure and economic feasibility, effective fire extinguishing method due to the occurrence of fire in the subway platform has not been established for over a year after the Daegu subway fire disaster has occurred.
