Problems solved by technology

[0003] One way to deal with it is to select the corresponding exhaust (smoke) fan and exhaust the smoke through the exhaust (smoke) pipe installed on the top of the platform rail area. In this way, the cross-sectional area of ​​the exhaust (smoke) pipe is very large, and the entire platform of the station needs to be exhausted. It is difficult to maintain the exhaust (smoke) pipe on the top of the catenary in the track area, and the aging of the air pipe will bring safety hazards after several years

Embodiment Construction

[0016] The features of the present invention and other related features will be further described in detail below in conjunction with the accompanying drawings through embodiments, so as to facilitate the understanding of those skilled in the art:

[0017] like Figure 1~2 As shown, the marks in the figure are: rail area 1, smoke exhaust pipe 2, air supply pipe 3, platform waiting area 4, air supply pipe 5, rail area 6, smoke exhaust pipe 7, damper 8, damper 9, Concentrated air return port 10, centralized air return port 11, heat exhaust chamber 12, air valve 13, air valve 14, air supply chamber 15.

[0018] Example: such as figure 1 , 2 As shown, the track area 1 and the track area 6 are the track areas of the up and down subway trains, respectively located on both sides of the platform waiting area 4, and the exhaust air chamber 12 is located on one side of the platform waiting area 4. The top of 4 in the platform waiting area is provided with air supply pipe 3 and air su...

Abstract

The invention relates to ventilation and fire protection in track traffic, in particular to a subway platform ventilation and smoke removal distribution structure in a station with an opened-closed system. The subway platform ventilation and smoke removal distribution structure is characterized in that a smoke removal pipe is externally connected with an air supply pipe, the air supply pipe is communicated with a small air removal chamber by the smoke removal pipe, and a control valve is arranged at the connecting part of the smoke removal pipe and the small air removal chamber. The subway platform ventilation and smoke removal distribution structure has the advantage that as the arranged smoke removal pipe is communicated with the air supply pipe, an air (smoke) removal fan can carry out uniform smoke removal on a station platform by the smoke removal pipe and the air supply pipe. The reconstruction cost of the platform is reasonable; and the structure can be adopted under the conditions that the station construction can be influenced by conditions such as piping and the like, the height of the platform can not reach the normal height, a space does not exist for arranging an upper air removal pipe in a rail area, or an upper air removal pipe of a running subway is damaged, and the repair difficulty of the air removal pipe is extremely large due to the influence of a contact network and normal running requirements, so that the air flow composition for normal ventilation and fire hazard smoke removal of the station can be met simultaneously.

Description

technical field [0001] The invention relates to rail transit ventilation and fire protection, in particular to an opening and closing system station subway platform ventilation and smoke exhaust layout structure. Background technique [0002] When the underground rail transit station adopts the open and closed system, the ventilation (air conditioning) system is responsible for the ventilation (air conditioning) and smoke exhaust of the station at the same time. [0003] One way to deal with it is to select the corresponding exhaust (smoke) fan and exhaust the smoke through the exhaust (smoke) pipe on the top of the platform rail area. In this way, the cross-sectional area of ​​the exhaust (smoke) pipe is very large, and the entire platform of the station needs to be exhausted. It is difficult to maintain the exhaust (smoke) pipe located on the top of the catenary in the rail area, and the aging of the air pipe after several years will bring safety hazards. [0004] In subw...
