Description
Technical Field
The utility model relates to a rail transit station designs technical field, especially relates to a shallow ventilation structure who buries station of rail transit.
Background
Under the current rail transit construction background, the station burial depth is influenced by the line arrangement and the surrounding municipal pipe network, and under specific conditions, the station position can be arranged in a transition region of a line interval from an overhead to the underground, so that the station is set to be a station hall on the ground layer, and the underground layer is a shallow-buried type of a platform.
The buried depth of the line of the shallow station has many characteristics, such as small civil engineering excavation amount, small construction occupied area, convenient and fast fire evacuation and the like, but the biggest characteristic is that a local open section exists between the front section and the rear section. Due to the influence of the characteristics, part of shallow-buried stations adopt an open system in the internal ventilation mode of the public area, namely, the platform public area is not provided with a completely closed shielding door system, and the temperature reduction ventilation effect of the platform air conditioning system is achieved by using interval piston wind, so that the installation of the platform layer air conditioning system is omitted, and the effects of energy conservation and environmental protection are achieved.
On the other hand, because the shallow station platform layer is located underground, according to the relevant regulations in the subway design specification and the subway design fire standard, the platform of the subway station needs to be provided with mechanical smoke prevention and exhaust measures, and when the platform layer is in fire, the stair and the staircase mouth from the station hall to the platform are ensured to have downward airflow which can effectively prevent the smoke from flowing upwards, and the wind speed is not less than 1.5 m/s. However, in the shallow buried station in the open system mode, because the station layer and the rail running area are not strictly separated, the smoke discharge process is difficult to effectively organize under the working condition of fire, so that the conventional shallow buried station cannot meet the requirement of the wind speed in the standard at the evacuation stair opening, and positive pressure air supply must be adopted as an auxiliary measure.
The positive pressure air supply is an air conditioner and ventilation process method, namely, the air pressure of a place needing the air conditioner is larger than the air pressure of a critical area, and fresh air needs to be continuously supplemented on the premise of ensuring the air conditioner. The positive pressure blower is generally arranged at the escalator mouth from a station hall to a station in a public area, but because the positive pressure blower is large in size, if the positive pressure blower is directly arranged above the public area or near the escalator mouth, the use function of the public area can be sacrificed, and meanwhile, the visual effect of the public area is adversely affected.
