Description

Technical Field

[0001] The present invention relates to the technical field of subway station design, and specifically to an underground station and method for jointly constructing subway equipment management rooms and the upper cover of subway annexes. Background Art

[0002] Urban rail transit, as the backbone of modern urban public transportation, its underground construction method effectively solves problems such as the shortage of ground space, traffic congestion, and environmental noise in high-density urban areas, and maximally preserves the precious urban surface landscape and functional layout. Therefore, it has become the preferred solution for the transportation development of large and medium-sized cities around the world. However, this traditional fully underground construction mode also brings huge challenges. A fully functional underground station not only includes passenger transportation areas such as platforms and concourses, but also must be equipped with a large-scale equipment and management rooms, such as environmental control rooms, substations, communication signal rooms, etc. These annex facilities occupy a large amount of underground space, resulting in a sharp increase in the overall earthwork excavation volume of the station, directly pushing up the initial construction cost of the project, and often triggering complex existing underground pipeline relocations and ground road renovation projects, significantly extending the construction period. At the same time, the huge underground structure requires continuous mechanical ventilation, all-weather artificial lighting, and uninterrupted power drainage, all of which constitute heavy long-term operation and maintenance costs.

[0003] The design of traditional underground stations also has inherent limitations in terms of operation and maintenance and land use efficiency. All key equipment, especially heavy equipment such as large ventilation units and transformers, is placed deep underground. Once routine maintenance, fault repair, or even replacement is required, it must be carried out through the reserved narrow passageways. The operating space is limited, and the hoisting operation is extremely difficult and risky. This not only significantly increases the operation and maintenance costs of large equipment, but also has a potential impact on the normal operation of the station.

[0004] In addition, subway entrances, ventilation shafts, and other annex structures themselves need to occupy a certain amount of ground land resources. However, in the traditional mode, the functions of these ground annex buildings are often relatively single, and the potential for integrating with the main functions of the station has not been fully explored, resulting in a waste of land resources. Especially in the urban center where every inch of land is precious, the maximum land value has not been realized. Summary of the Invention

Detailed implementation manners

[0053] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings of the present invention specification. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0054] Please refer to the attached Figure 1 - attached Figure 7 , the embodiments of the present invention provide an underground station with the combined construction of subway equipment management rooms and the above-ground annex of the subway, including: an underground part and a ground annex part combined with the equipment management rooms;

[0055] The underground part includes a station platform 1 located on the second basement floor and a station concourse 11 located on the first basement floor;

[0056] On the station platform 1, there are a public area toilet 4, a sewage pump room 5, a wastewater pump room 6, a platform door equipment room 7, and a lighting power distribution room 8;

[0057] The station platform 1 is connected to the station concourse 11 through an elevator 2 and a stairway 3; on both sides of the station concourse 11, there are a mechanical air duct 14 and a mechanical fan 15;

[0058] The ground annex part is located outside the scope of the planning road red line 33 and includes a subway entrance 13 and a subway entrance 2 32;

[0059] The station concourse 11 is connected to the underground parts of the subway entrance 13 and the subway entrance 2 32 through a passage 12 and a stairway 3 respectively;

[0060] The underground part is connected to the above-ground accessory part through the fire stairs 9, the strong and weak electrical shafts 10, the air duct 17, and the cable shaft corridor 34;

[0061] Gate machines 31 are installed on the ground floors of the subway entrance 13 and the subway entrance 32 to divide the paid area 20 and the non-paid area 21, and entrance channels 22 connecting to other quadrants are provided underground;

[0062] Other equipment management rooms 36 are arranged in the above-ground accessory part, where:

[0063] The rooms built jointly with the subway entrance 13 include the environmental control machine room 18, the environmental control electric control room 19, and the ground air shaft 16, and shops 35 can be set up;

[0064] The rooms built jointly with the subway entrance 32 include the station control room 23, the integrated monitoring equipment room 24, the fire pump room 25, the communication equipment room 26, the signal equipment room 27, the police room 28, the station substation 29, and the environmental control machine room 18 and the environmental control electric control room 19;

[0065] Louver windows and daylighting windows 30 are opened on the other equipment management rooms 36.

[0066] Specifically, the core area for passengers to board and alight, that is, the station platform 1 on the second basement floor, has been streamlined to only retain the necessary public area restrooms 4 for passengers, the sewage pump room 5 and the wastewater pump room 6 for treating the wastewater in the station, the platform door equipment room 7 to ensure the normal operation of the platform screen doors, and the basic lighting and power distribution room 8. Passengers move vertically between the platform and the station concourse 11 on the first basement floor through barrier-free elevators 2 and efficient escalators and stairways 3. The key ventilation and smoke exhaust functions of the station are efficiently executed by mechanical fans 15 in the mechanical air ducts 14 on both sides of the concourse, and the air exchange is completed through the ground air shafts 16. The revolutionary aspect of this design is that the vast majority of complex other equipment management rooms 36 have been innovatively separated from the underground structure and moved to the ground annex buildings jointly constructed with the subway entrance one 13 and the subway entrance two 32 outside the planned road red line 33. Not only is the paid area 20 and the non-paid area 21 efficiently demarcated by turnstiles 31 on the entrance ground floor, reducing the scale of the underground public area, but also the underground space is used to set up entrance channels 22 connecting other quadrants to maximize the passenger flow attraction; more importantly, this ground integration gives the station unprecedented beneficial effects. For example, the environmental control machine room 18 and the environmental control electric control room 19 jointly constructed with the subway entrance one 13, and the flexibly set shops 35 achieve the maximization of land value. In the comprehensive building jointly constructed with the subway entrance two 32, the station control room 23, the integrated monitoring equipment room 24, the fire pump room 25, the communication equipment room 26, the signal equipment room 27 and the police station 28 for ensuring the safe operation of the station, as well as the station substation 29 providing core power are centrally set up. These ground rooms make full use of natural lighting and ventilation by opening louvers and daylighting windows 30, greatly reducing the energy cost of long-term operation. At the same time, the underground and the ground maintain the necessary functional connection through vertical channels such as the fire stairs 9, the strong and weak electric wells 10, the air duct one 17 and the cable well corridor 34. This move not only greatly reduces the initial earth excavation and construction costs, but also fundamentally solves the pain points of difficult maintenance and hoisting of large equipment in the underground environment, significantly reducing the maintenance cost of the whole life cycle.

[0067] Please refer to the appendix Figure 1 - Appendix Figure 7 , the embodiment of the present invention provides a construction method for an underground station with the integrated construction of subway equipment management rooms and the subway annex overlying, including the following steps:

[0068] Step 1: Build the station platform 1 on the second basement floor within the underground foundation pit range within the road red line, and set elevators 2 and escalators and stairways 3 connecting to the first basement floor in the platform.

[0069] Step 2: Set a small number of necessary equipment rooms such as the public area restrooms 4, the sewage pump room 5, the wastewater pump room 6, the platform door equipment room 7, the lighting and power distribution room 8, the fire stairs 9, and the strong and weak electric wells 10 on both sides of the platform.

[0070] Step 3: Construct the station concourse 11 on the first basement floor within the scope of the underground foundation pit. In the public area of the concourse, set up Passage 12 and escalators 3 to connect the subway entrances 13 on both sides.

[0071] Step 4: Set up mechanical air ducts 14 and mechanical fans 15 on both sides of the concourse to achieve the functions of the interval piston air shaft and smoke exhaust, and connect them to the ground air shaft 16 through passages.

[0072] Step 5: Set up cable strong and weak electric wells 10, Air Duct 17, and fire stairs 9 on both sides of the concourse, and connect them to the ground annex management rooms through passages to achieve the functions of fire protection and management of the station.

[0073] Step 6: Set the subway entrance 13 outside the ground road red line range at one end of the station. Utilize the area above the open-cut entrance range to set up the environmental control machine room 18, environmental control electric control room 19, and necessary equipment rooms for the ground air shaft 16.

[0074] Step 7: Set the subway entrance 13 outside the ground road red line range at one end of the station. Set up ticket gates 31 in the ground area of the entrance to divide the paid area 20 and the non-paid area 21 to meet the function of passengers entering and leaving the station.

[0075] Step 8: Set the subway entrance 13 outside the ground road red line range at one end of the station. Set up an entrance passage 22 connecting other quadrants underground.

[0076] Step 9: Set the subway entrance 32 outside the ground road red line range at the other end of the station. Set up the station control room 23, integrated monitoring equipment room 24, fire pump room 25, communication equipment room 26, signal equipment room 27, and police room 28 on the first and second floors of the ground, which are important management and equipment rooms of the station, to meet the functional requirements of station operation and fire protection.

[0077] Step 10: Set the subway entrance 32 outside the ground road red line range at the other end of the station. Set up the environmental control machine room 18, environmental control electric control room 19, and station substation 29, all important equipment rooms of the station, on the third floor of the ground to meet the functional requirements of ventilation and air conditioning, fire protection, and electricity consumption of the station.

[0078] Step 11: Open necessary louvers and daylighting windows 30 in the station equipment management rooms to meet the relevant smoke exhaust and lighting requirements of the rooms.

[0079] Step 12: Set the subway entrance 32 outside the ground road red line range at the other end of the station. Set up ticket gates 31 in the ground area of the entrance to divide the paid area 20 and the non-paid area 21 to meet the function of passengers entering and leaving the station. Step 13: Set the subway entrance 32 outside the ground road red line range at the other end of the station. Set up an entrance passage 22 connecting other quadrants underground.

[0080] Combine the main equipment management rooms of the subway with the overlying subway annexes. On the premise of meeting the underground laying requirements of urban rail transit, significantly reduce the structural excavation length of the underground part of the subway, which can effectively reduce demolition and pipeline relocation, and lower the construction and maintenance costs of ventilation, lighting, and drainage facilities.

[0081] On the basis of retaining the advantages of underground construction of the subway, the construction method adjusts the main equipment and management rooms of the subway to the ground for construction, reducing the length and scope of the underground excavation structure, reducing demolition and pipeline relocation, and lowering the construction cost.

[0082] The construction method combines the equipment and management rooms with the subway annexes and constructs them in combination with the original excavation scope of the subway annexes without additional demolition and land acquisition.

[0083] The ground equipment management rooms are connected to the underground part through air duct 17, fire staircase 9, subway entrance 13, and subway entrance 32 to meet the station use and fire protection functions.

[0084] Necessary louvers and daylighting windows 30 are opened in the ground equipment and management rooms to utilize natural smoke exhaust and natural daylighting to meet the relevant smoke exhaust and lighting requirements of the rooms, reducing the construction and maintenance costs of ventilation, lighting, and drainage facilities.

[0085] The equipment and management rooms are located on the ground. The mechanical fan 15 and transformer equipment can be repaired and hoisted using the ground, reducing the operation and maintenance costs of large equipment facilities.

[0086] Turnstiles 31 are set in the ground areas of subway entrance 13 and subway entrance 32 to divide the paid area 20 and the non-paid area 21. The public area area of the underground station concourse 11 is correspondingly reduced, and the construction and maintenance costs of ventilation and lighting facilities are correspondingly lowered.

[0087] Entrance channels 22 connecting other quadrants are set underground at subway entrance 13 and subway entrance 32 to attract and serve the passenger flow in each quadrant.

[0088] Working principle: By coordinating the operation of the underground part of the subway station with the ground annex part combined with other equipment management rooms 36, an efficient and economical subway station construction and operation mode is realized. Specifically, when operating, passengers board and alight at the station platform 1 on the second basement floor. Only a small number of necessary equipment rooms are set on this platform layer, such as the public area toilet 4, sewage pump room 5 and wastewater pump room 6 for treating sewage, platform door equipment room 7 for ensuring platform safety, and lighting and power distribution room 8. Passengers rise to the station concourse 11 on the first basement floor through the elevator 2 and escalators 3. The mechanical air ducts 14 and mechanical fans 15 on both sides of the concourse are responsible for handling the piston wind in the interval and smoke exhaust during a fire, and are connected to the ground air shaft 16 through the passage and discharged to the ground;

[0089] Subsequently, passengers go through passageway 12 and escalator 3 in the concourse to subway entrance 13 and subway entrance 32, which are respectively located on both sides of the planned road red line 33. At the ground floor of the entrances, the fare collection area 20 and the non-fare collection area 21 are demarcated and passengers enter and exit through the installed turnstiles 31. Meanwhile, underground passageways 22 connecting other quadrants are set at each entrance to attract a wider passenger flow.

[0090] Most of the core functions of the station are moved to the ground annex buildings built in conjunction with the entrances. In the building built in conjunction with subway entrance 13, there are an environmental control machine room 18 and an environmental control electric control room 19 for the station's environmental control, and shops 35 can be flexibly set up to increase revenue. In the multi-story building built in conjunction with subway entrance 32, the core of the station operation is concentrated, including the station control room 23, integrated monitoring equipment room 24, fire pump room 25, communication equipment room 26, signal equipment room 27 and police office 28 on the first and second floors, as well as the station substation 29, another set of environmental control machine room 18 and environmental control electric control room 19 on the third floor. These other equipment management rooms 36 on the ground achieve natural ventilation and lighting through the installed louvers and daylighting windows 30, greatly reducing energy consumption.

[0091] Moreover, the underground part and the ground annex part are closely connected through the fire stairs 9, strong and weak electric wells 10, air duct 17 and cable well corridor 34, ensuring seamless docking and safety and reliability in terms of fire protection, electricity, communication and management. This way of moving the equipment and management rooms to the ground makes the maintenance and hoisting of heavy equipment such as mechanical fans 15 and transformers in the station substation 29 extremely convenient, significantly reducing the operation and maintenance costs.

[0092] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
