Description

Technical Field

[0001] This application relates to the field of subway station ventilation, and more specifically, to a layout structure of subway station entrances and ventilation systems and a subway station. Background Technology

[0002] Subway stations are typically located underground. To ensure air circulation and passenger comfort and safety within these stations, ventilation ducts are installed underground, while ventilation shafts are located above ground. These underground ventilation ducts and shafts facilitate ventilation, regulate temperature, control harmful gas concentrations, provide emergency smoke extraction, and prevent moisture buildup.

[0003] Currently, the ventilation ducts and entrances / exits of subway stations are arranged separately, resulting in inefficient use of underground space. On the ground, the entrance / exit pavilions and ventilation shafts are scattered and difficult to arrange neatly, which seriously affects the urban landscape and the land area occupied above the subway.

[0004] Therefore, how to provide a ventilation system for subway stations that at least partially solves the above-mentioned technical problems has become a technical problem that needs to be solved in this field. Utility Model Content

[0005] In view of this, this application proposes an arrangement structure for subway station entrances and ventilation systems, as well as a subway station.

[0006] According to the first aspect of this application, a layout structure for a subway station entrance and ventilation system is proposed. The ventilation system of the subway station is set adjacent to the entrance passage. The ventilation system of the subway station includes: a ventilation shaft, which is set at the top of the subway station entrance passage and is distributed in a straight line with the subway station entrance ground pavilion; and an air duct, which is set on the side of the subway station entrance passage and is connected to the internal space of the ventilation shaft.

[0007] Preferably, the ventilation duct is bent and located on the side of the entrance / exit passage of the subway station, and is connected to the ventilation shaft.

[0008] Preferably, the ventilation duct and / or the ventilation shaft are not connected to the entrance / exit passage of the subway station.

[0009] Preferably, the ventilation shafts are arranged in a straight line at the top of the entrance / exit passage of the subway station.

[0010] Preferably, the ventilation shaft includes: a piston ventilation shaft, an exhaust ventilation shaft, and a fresh air ventilation shaft.

[0011] Preferably, the ventilation shafts share a common wall but are spatially independent of each other.

[0012] Preferably, the cross-section of the ventilation shaft is L-shaped.

[0013] Preferably, the air duct includes: a piston air duct, an exhaust air duct, and a fresh air duct.

[0014] Preferably, the air ducts share a common wall but are spatially independent of each other.

[0015] According to a second aspect of this application, a subway station includes the layout structure of subway station entrances and exits and ventilation systems.

[0016] The proposed layout structure for the subway station entrances and ventilation system utilizes the underground space of the subway station in a compact arrangement between the ventilation system and the entrance / exit passage structure. On the other hand, placing the ventilation shafts on the top of the entrance / exit passage can effectively save the subway station's floor space. On the ground, the ventilation shafts are distributed in a straight line with the station entrance / exit ground pavilions, making the ventilation shafts neatly arranged and improving the overall aesthetics of the urban subway station.

[0017] Other features and advantages of this application will be described in detail in the following detailed description section. Attached Figure Description

[0022] The technical solution of this application will now be described in detail with reference to the accompanying drawings and embodiments.

[0023] like Figure 1 As shown, according to the first aspect of this application, an arrangement structure for an entrance and ventilation system is proposed. The ventilation system of the subway station is set adjacent to the entrance passage. The ventilation system of the subway station includes: a ventilation shaft, which is set at the top of the entrance passage of the subway station and is distributed in a straight line with the ground pavilion of the entrance passage of the subway station; and an air duct, which is set on the side of the entrance passage of the subway station and is connected to the internal space of the ventilation shaft.

[0024] The ventilation shafts mentioned above are directly installed on the top of the entrance and exit passages of the subway station, allowing the ventilation shafts to be stacked with the entrance and exit passages, making full use of underground space and effectively saving underground space.

[0025] The aforementioned ventilation ducts are located on the side of the entrance and exit passages of the subway station, at the same horizontal level as the entrance and exit passages. The ventilation duct path is relatively simple, which can reduce airflow resistance and help improve the overall ventilation effect of the ventilation system. It can also reduce the space occupied by the ventilation ducts, improve the space utilization of the station, simplify structural design and construction, reduce the required support structures, pipe connections and equipment installations, and facilitate maintenance. Maintenance personnel can directly access the ventilation ducts through the entrance and exit passages, improving maintenance efficiency.

[0026] The aforementioned ventilation shafts are not interconnected with the entrance / exit passages. The ventilation shafts expel exhaust gases, heat, and moisture entering the entrance / exit passages, while introducing fresh outside air through the entrance / exit passages into the ventilation ducts. In this application, the internal spaces of the ventilation shafts and ventilation ducts are directly connected, preventing exhaust gases or toxic / harmful gases from entering the entrance / exit passages and affecting the comfort and safety of pedestrians or passengers. Secondly, it allows for independent airflow control, ensuring more efficient airflow in different areas, effectively preventing cross-contamination, preventing air backflow, and ensuring safe evacuation of passengers in emergencies.

[0027] like Figure 3 As shown, according to a preferred embodiment of this application, the air duct can be bent and installed on the side of the subway station entrance / exit passage, communicating with the ventilation shaft. The ventilation shaft is vertically installed at the top of the subway station entrance / exit passage, and a portion of the air duct is at the same horizontal level as the entrance / exit passage. Near the entrance / exit passage, in order to communicate with the ventilation shaft installed at the top of the entrance / exit passage, the air duct is bent, increasing its height so that the air duct communicates with the ventilation shaft. The bent air duct makes airflow more uniform, avoiding air stagnation areas or dead zones. The connection with the ventilation shaft helps ensure smooth airflow within the air duct. Furthermore, it prevents rainwater from directly splashing onto the civil defense equipment.

[0028] like Figure 2 and Figure 3As shown, to reduce the impact of polluted gases generated inside the ventilation duct on passengers or pedestrians, preferably, the ventilation duct and / or the ventilation shaft can be disconnected from the subway station entrance / exit passage. This prevents polluted gases from entering the passage, and exhaust gases, pollutants, and toxic and harmful gases in the ventilation duct cannot flow back or diffuse into the passage area. This ensures that the air in the entrance / exit passage remains fresh, preventing polluted gases from affecting passenger comfort and safety; it also prevents harmful gases from accumulating inside the station. In emergencies, such as in the event of a fire, it can minimize the accumulation of dense smoke in the entrance / exit passage or its reversal into the station.

[0029] like Figure 1 As shown, to enhance the consistency and aesthetics of the urban landscape, the ventilation shafts are preferably arranged in a straight line above the entrance and exit passages of the subway station. On one hand, by sharing walls with the entrance and exit passages, the ventilation shafts save on construction materials and reduce construction costs. On the other hand, the straight-line arrangement of the ventilation shafts ensures they are aligned with the subway station entrances and exits, resulting in a more regular ground footprint, enhancing the urban landscape above the subway station, and reducing the subway station's ground footprint, thus minimizing its impact on urban land use.

[0030] To ensure air quality within the underground station and prevent excessive air pressure during high-speed train operation, the ventilation shafts preferably include: piston ventilation shafts, exhaust ventilation shafts, and fresh air shafts. Piston ventilation shafts are primarily used when a train is running at high speed. The front of the train entering the underground tunnel generates a high-pressure wave, while the rear generates a negative-pressure wave. The various fluctuations generated by the train's movement within the tunnel gradually accelerate the air, causing it to move with the train and creating a piston effect within the tunnel. The piston ventilation shafts utilize this piston effect through air ducts to facilitate air convection and exchange within the tunnel. An appropriate number of piston ventilation shafts can be used; in this application, two are preferred. This improves airflow and pressure differential. The two piston ventilation shafts can be positioned at different locations within the station, forming symmetrical airflow paths, distributing airflow more evenly within the station, and avoiding localized airflow obstruction. They also balance the air pressure difference between the station and the tunnel, preventing airflow turbulence or congestion that might occur with ventilation shafts on one side. The aforementioned ventilation shafts can effectively expel heat, polluted areas, and exhaust fumes generated within the station, especially during peak passenger flow when air quality is poor, thus maintaining fresh and unobstructed airflow. Conversely, the aforementioned fresh air shafts can introduce fresh outside air into the station, regulating temperature and humidity, providing ample oxygen, and ensuring good air quality.

[0031] To save space in underground stations and make them more compact, preferably, the ventilation shafts can share walls but are spatially independent. This compact arrangement of ventilation shafts, sharing walls, saves construction materials and construction area, reducing construction costs; the structural connections between ventilation shafts are tighter, enhancing the overall stability of the station; the spatial independence of the ventilation shafts ensures independent and effective airflow, avoiding airflow interference between different ventilation shafts; and improving the efficiency, reliability, and safety of station ventilation.

[0032] To ensure effective ventilation, the ventilation shaft is preferably L-shaped. The L-shaped cross-section optimizes the airflow path, improves ventilation efficiency and airflow stability, and effectively utilizes limited space while increasing the cross-sectional area of ​​the airflow. This enhances structural stability, reduces air stagnation, and improves air exchange, making it particularly suitable for station environments with narrow spaces and high ventilation requirements. The L-shaped cross-section can flexibly adapt to complex layouts, ensuring reliable ventilation operation of the ventilation shaft in high passenger flow and compact spaces.

[0033] To further ensure that the ventilation shafts can independently achieve their ventilation function, preferably, the air ducts may include: piston air ducts, exhaust air ducts, and fresh air ducts. These air ducts are respectively connected to their corresponding ventilation shafts. To ensure independent ventilation, the air ducts share a wall but are spatially independent. The configuration within each air duct is based on its respective function, such as installing a ventilation fan. The air ducts can be installed in appropriate locations, as long as they can connect to the ventilation shafts. In this application, for example... Figure 1 As shown, the air duct is set perpendicular to the entrance and exit passage at the bottom of the ventilation shaft, reducing the number of air ducts and increasing the ventilation effect. In order to save underground space, the entrance and exit passage is usually set in two sections at the corner, and the air duct is set parallel to the other entrance and exit passage, further saving the utilization of underground space.

[0034] According to a second aspect of this application, a subway station includes the layout structure of subway station entrances and exits and ventilation systems.

[0035] The proposed layout structure for the subway station entrances and ventilation system utilizes the underground space of the subway station in a compact arrangement between the ventilation system and the entrance / exit passage structure. On the other hand, placing the ventilation shafts on the top of the entrance / exit passage can effectively save the subway station's floor space. On the ground, the ventilation shafts are distributed in a straight line with the station entrance / exit ground pavilions, making the ventilation shafts neatly arranged and improving the overall aesthetics of the urban subway station.

[0036] The preferred embodiments of this application have been described in detail above. However, this application is not limited to the specific details of the above embodiments. Within the scope of the technical concept of this application, various simple modifications can be made to the technical solution of this application, and these simple modifications all fall within the protection scope of this application.

[0037] It should also be noted that the various specific technical features described in the above embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, this application will not describe the various possible combinations separately.

[0038] Furthermore, various different embodiments of this application can be combined in any way, as long as they do not violate the spirit of this application, they should also be regarded as the content disclosed by this invention.
