Structure.
Background technique
Under urban rail transit construction background now, station buried depth is by line arrangement, the influence of periphery city planting ductwork, specific
Under the conditions of, erect-position, which will appear, is arranged in railroad section by the overhead transitional region for switching to underground, therefore station is set as ground
Layer is subway concourse, and basement one is the shallow embedding pattern of platform.
The route buried depth at shallow embedding station has a various features, such as civil engineering excavated volume is few, construction area small scale, and fire-fighting is dredged
The features such as convenient is dissipated, but maximum feature is that its front and back section has local open section.Exactly because the influence of this feature, one
Part shallow embedding station uses open system in the inner ventilation mode of public area, i.e. platform public area is not provided with completely enclosed formula
Screen door is reached the cooling that platform air-conditioning system is played using section Piston Action Wind and leads to wind action, to eliminate
The installation of station layer air-conditioning system has reached energy-saving and environment-friendly effect.
But then, since shallow embedding station platform layer is located underground, according to " metro design code " and " Metro Design is anti-
Fiery standard " in relevant regulations, the platform of subway station will be arranged mechanical smoke evacuation measure, and when fire occurs for station layer, Ying Bao
Demonstrate,proving subway concourse has the downdraught that can effectively prevent flue gas upward at the stair and staircase mouth of platform, and wind speed is no less than
1.5m/s.But since the shallow embedding station under open system mode is due to station layer and the area Gui Hang is not formed strictly disjoints, in fire
It is difficult effectively to organize smoke evacuation process under operating condition, conventional Shallow-Embedded Under-Ground station is caused to be unable to satisfy the wind in specification in escape stair mouth
Speed requires, it is necessary to take forced draft as ancillary measure.
Forced draft is the process of a kind of air-conditioning and ventilation, i.e., the place air pressure of required air-conditioning is greater than critical zone
Air pressure ceaselessly will have fresh air to fill under the premise of guaranteeing air-conditioning.Forced draft machine is typically located at public area subway concourse and arrives at a station
At the building staircase mouth of platform, but because forced draft machine equipment is bulky, if being directly arranged at public area top or building staircase mouth
Near portion, then the use function of public area can be sacrificed, while adverse effect is generated to public area visual effect.
