Problems solved by technology
The wind field of the tunnel next to the underground island subway platform is too strong (fast speed and large flow), which will not only increase the air leakage of the screen door, but also increase the wind noise, aggravate the vibration of the screen door, or blow to the platform and cause waiting passengers Discomfort (when the screen door is "half-height", the wind in the tunnel will blow towards the platform)

Embodiment Construction
[0027] The present invention will be further described in detail below in conjunction with the accompanying drawings.
[0028] For the first example, see figure 2 Shown:
[0029] The method for controlling the wind field of a tunnel next to an underground island type subway platform includes a step of weakening the wind field. The step of weakening the wind field is to weaken the incoming wind at a position close to the platform at the entrance end of the tunnel.
[0030] Wherein, the wind field weakening step includes the measures of setting a wind field weakening structure at the position near the station platform at the entrance end of the tunnel, and the wind field weakening structure includes a detour air duct 10, and the detour air duct 10 runs through the underground island subway The platform connects the tunnels on both sides of the underground island subway platform.
[0031] During implementation, it is preferable to install a top plate (not shown in the figure) ...

The invention discloses a regulation method of a wind field of a tunnel beside an underground island type subway platform. The regulation method of the wind field of the tunnel beside the undergroundisland type subway platform includes the wind field weakening step, that is, the wind on the position, close to the platform, of the subway entry end in the tunnel is weakened. According to the regulation method of the wind field of the tunnel beside the underground island type subway platform, the speed and / or strength (flow capacity) of the wind field flowing through the platform in the tunnel can be weakened, the function of wind field regulation is achieved, the difficulty of sealing safety doors by the wind field of the tunnel beside the underground island type subway platform is lowered,the shaking degree of the safety doors is lowered, the condition that the wind in the tunnel blows strongly towards passengers waiting on the platform is avoided, and the use experience is improved.
Description
technical field [0001] The invention belongs to the field of subways, and in particular relates to a method for regulating and controlling the wind field of a tunnel next to an underground island type subway platform. Background technique [0002] The underground island-type subway platform is that the platform is in the middle, and there are two-way running subway vehicles on both sides of the platform. The announcement number in the prior art is: CN108346369A document, discloses " a kind of novel subway station model ", and this " a kind of novel subway station model " promptly comprises underground island type subway platform. In addition, in the document with the announcement number: CN106979802A, a "system and method for detecting air leakage of a subway platform screen door" is disclosed. This technical solution involves a kind of screen door ( Also known as "safety door") air leakage system and method, and in its background technology, the impact of screen door air l...
