Description

Technical Field

[0001] This invention relates to the field of building technology, specifically to a shared atrium building structure that integrates underground rail transit stations and urban spaces. Background Technology

[0002] Urban rail transit has garnered significant attention due to its efficiency, land conservation, energy saving, and green features, leading to a surge in the number of rail transit hubs. Simultaneously, the development of underground space is also intensifying. The passenger flow brought by rail transit as a public facility can boost commercial activity, while underground commercial space can support the construction of rail transit-related properties. The natural complementarity between subway stations and commercial spaces makes the integrated development of rail transit and commercial space an inevitable trend in the intensive development of urban space. This aims to achieve a high-quality, green, shared, and open underground urban integrated space. Based on this background, this invention proposes a media space form—a shared atrium for underground rail transit and urban space—integrating transportation, commercial value, public space, and human-centered living. Summary of the Invention

[0003] This invention provides a shared atrium architectural structure that integrates underground rail transit stations and urban spaces. Its purpose is to solve the technical problem of connecting and sharing subway and urban spaces, enabling the integrated and intensive use of rail transit and commercial spaces. This effectively improves the spatial quality of both, enhancing the experience for passengers and customers. A well-designed and high-quality nodal space within the rail transit complex will be highly attractive to consumers, thus increasing the vitality of the rail transit complex.

[0004] The technical solution of this invention is implemented as follows: A shared atrium architectural structure that integrates underground rail transit stations and urban spaces includes three underground floors. The first underground floor is the urban space layer 1, the station occupies the space of the second to third underground floors, and a shared atrium 19 is set up in a part to integrate and connect the three spaces: the urban space of the first underground floor, the public area of ​​the station hall on the second underground floor, and the public area of ​​the platform on the third underground floor. The basement level includes commercial space and has a floor opening 31 that connects to the public area of ​​the station concourse below. The second underground level includes the N5 line concourse level, the N1 line and N2 line concourse levels, and the S1 line concourse level, all located on the same floor. The N5 line concourse level has a north-south oriented N5 line track 17, and public areas 3.5 and 4.6 of the N5 line concourse, and equipment area 2.7 of the N5 line, located on both sides of the N5 line track. Equipment area 2.7 is located on the east-west sides of public areas 3.5 and 4.6. The N5 line track 17 passes through the east-west oriented N1 and N2 line concourse levels and the S1 line concourse level. Public areas 3.5 and 4.6 of the N5 line concourse level are located between the N1 and N2 line concourse levels and the S1 line concourse level. The station concourse level includes public areas 1-2 and 2-3, which are divided into east-west sides by the N5 line track, and equipment area 1-4 and entrance / exit 25 at the east and west ends of the public areas; the S1 line concourse level includes public areas 5-8 and 6-9, which are divided into east-west sides by the N5 line track, and equipment area 3-10 at the east and west ends of public areas 5 and 6, and station entrance / exit 25; public areas 5-8, 3-5, 1-2, 6-9, 4-6, and 2-3 are interconnected in a north-south direction; equipment area 2-7, sunken courtyard space 24, and public area 1-2 or public area 2-3 are connected in a north-south direction. The underground three-level structure includes lines N1 and N2, line S1, and a platform level. Both lines N1 and N2 are island platforms, with one track on each side, forming a double-island flat platform configuration. Lines N1 and N2 are arranged side-by-side in an east-west direction. A platform common area 11 is provided between the two lines of line N1 and line N2, connected to the upper level's common area 2 or common area 3 via escalators 100. Equipment areas 4 12 are located at both ends of the platform common area 11 in the east-west direction. The underground three-level structure also includes line S1 and its platform common area 13, and equipment areas 2 14 at both ends, arranged parallel to and at intervals from lines N1 and N2. The S1 platform common area 13 is located on both sides of line S1 and connected to the upper level's common areas 5 8 and 6 9 via escalators 100. Lines N1, N2, and S1, along with line N5, form a four-line I-shaped, same-level, through-hall interchange station structure. In the common area 11 of the two platforms of lines N1 and N2 on the third underground level, there is a second opening 30 in the middle of the station slab, which connects to the station hall on the second underground level. At least one of the second openings 30 corresponds to the first opening 31 in the slab to form the shared atrium 19 connecting the first to third underground levels. The atrium is 40m long and 30m wide. The other second opening 30 forms the shared atrium 190 on the second to third underground levels.

[0005] The aforementioned shared atrium architectural structure integrates underground rail transit stations and urban spaces, wherein at the east and west ends of the N1N2 line, two sets of escalators are arranged in conjunction with the atrium to lead to the platform public areas in the public areas of the station halls, namely, public area 1, public area 2, and paid area.

[0006] The aforementioned shared atrium architectural structure that integrates underground rail transit stations and urban spaces includes a sunken courtyard space (24) on the north side of the public area one (2) and public area two (3) that leads to the ground and descends to the second underground floor. The courtyard is 90m long and 18m wide, introducing the green landscape of the courtyard into the station. The sunken courtyard space on the first underground floor leading to the second underground floor is connected by stairs and escalators. The sunken courtyard space (24) on the second underground floor can be reached through the shared atrium (19) or the shared atrium one (190).

[0007] The aforementioned shared atrium architectural structure integrates underground rail transit stations and urban spaces. Specifically, the shared atrium 19 comprises the N1 and N2 line station hall west public area floor slab opening 31 and the central slab floor slab opening 30, which integrate the platform, station hall, and the underground first-floor urban public commercial space 1. The shared atrium 19 is two spans wide. A flat glass roof forms a horizontal glass roof 20, slightly higher than the outdoor ground level, allowing sunlight to enter and creating a highly recognizable transfer and connection space.

[0008] The aforementioned shared atrium architectural structure integrates underground rail transit stations and urban spaces, wherein the N1 and N2 line concourses and the S1 line concourses are located on the second underground floor in an east-west direction, corresponding to the N1 and N2 line platforms and the S1 line platform on the third underground floor.

[0009] This invention not only breaks away from the traditional layout of subway station concourses and platforms as two independent spaces, enriching the spatial hierarchy of the subway, enhancing the spatial experience, and enabling passengers to visualize the vertical space, but also eliminates the visual obstruction between the station and the city above it.

[0010] This invention integrates the design of rail transit stations and underground urban spaces, encompassing aspects such as function, structure, space, civil defense, electromechanical systems, construction, and specialized technologies. Simultaneously, the rail transit stations and underground urban spaces are clearly demarcated, forming independent systems for fire protection and operation management.

[0011] The beneficial effects of this invention are: 1) Based on the integration of stations and cities, the subway stations are conveniently and efficiently connected with underground commercial and office functions, forming a highly integrated three-dimensional space centered on the rail station. The compact structure of the four underground rail transit stations with the same floor hall transfer station and the shared atrium architectural structure formed by the integration of urban space enhance the quality of urban space, realize the intensive development of land, and promote regional economic development.

[0012] 2) Subway stations based on station-city integration are often located below urban space. This invention provides a way to deal with this type of station space. By setting up an atrium space, the originally dull subway space is liberated and integrated with the underground urban space above. By setting up a glass roof on the top plate, sunlight is introduced into the atrium, creating an underground "sunshine hub".

[0013] 3) Based on the integration of station and city, subway stations should focus on the communication between various functional spaces. By setting up a high atrium space, multiple spaces and stations can be integrated and connected, making the flow of people on each floor clearly visible and making it easier for passengers to confirm their walking routes in advance. 4) Subway stations based on station-city integration differ from conventional subway designs in key engineering technologies such as fire protection and civil defense. This invention provides a method for addressing several key engineering technologies. The subway station and underground space are integrated complexes, representing important economic objectives. The main structure is calculated based on the equivalent static load of nuclear-grade 6 and conventional-grade 6 civil defense, improving overall tamper resistance. For equipment areas, partial enclosure and protection are implemented through the installation of open walls and protective equipment. Public areas only undergo structural reinforcement; the hub will not serve as a personnel shelter in wartime. Attached Figure Description

Detailed Implementation

[0016] The specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings. See Figure 1-5 As shown, the present invention discloses a shared atrium architectural structure that integrates underground rail transit stations and urban spaces, comprising three underground levels, wherein the first underground level is the urban space level 1, the station occupies the space of the second to third underground levels, and a shared atrium 19 is partially set up to integrate and connect the three spaces: the urban space of the first underground level, the public area of ​​the station hall level of the second underground level, and the public area of ​​the platform level of the third underground level. See Figure 1 As shown, the underground urban space layer 1 includes commercial space and has a floor opening 31 that connects and integrates with the public area space of the station concourse layer below. See Figure 2 As shown, the second underground level includes the N5 line concourse level, the N1 line and N2 line concourse levels, and the S1 line concourse level, all located on the same floor. The N5 line concourse level has the N5 line track 17 arranged in a north-south direction, and public areas 3.5 and 4.6 of the N5 line concourse, and equipment area 2.7 of the N5 line, located on both sides of the N5 line track. The equipment area 2.7 of the N5 line is located on both sides of public areas 3.5 and 4.6 in an east-west direction. Figure 1-3The orientation of the central position is set as north at the top, south at the bottom, west on the left, and east on the right; the N5 line track 17 passes through the station halls of the N1 and N2 lines, which are arranged in an east-west direction, and the station hall of the S1 line; the public areas 3 and 4 of the N5 line platform are located between the station halls of the N1 and N2 lines and the station hall of the S1 line; the station halls of the N1 and N2 lines include public areas 1 and 2, public areas 2 and 3, which are divided into east-west sides by the N5 line track, and equipment areas 1 and 4 and entrances / exits 25 located at the east and west ends of the public areas. The S1 line station concourse includes public areas 5 (8), 6 (9), and equipment areas 10 located at the east and west ends of public areas 5 and 6, which are divided by the N5 line track. Station entrances / exits are also included. Public areas 5 (8), 3 (5), 1 (2), 6 (9), 4 (6), and 2 (3) are interconnected in a north-south direction. Equipment area 2 (7) and the sunken courtyard space 24 of the N5 line are sequentially connected to public area 1 (2) or public area 2 (3) in a north-south direction. See Figure 3 As shown, the underground three-level structure includes lines N1 and N2, line S1, and a platform level. Both lines N1 and N2 are island platforms, with one track on each side, forming a double-island flat platform configuration. Lines N1 and N2 are arranged side-by-side in an east-west direction. A platform common area 11 is provided between the two lines of line N1 and line N2, connected to the upper level's common area 2 or common area 3 via escalators 100. Equipment areas 4 12 are located at both ends of the platform common area 11 in the east-west direction. The underground three-level structure also includes line S1 and its platform common area 13, and equipment areas 2 14 at both ends, arranged parallel to and at intervals from lines N1 and N2. The S1 platform common area 13 is located on both sides of line S1 and connected to the upper level's common areas 5 8 and 6 9 via escalators 100. Lines N1, N2, and S1, along with line N5, form a four-line I-shaped, same-level, through-hall transfer station structure, facilitating convenient transfers. See Figure 1 , 2 As shown in Figures 3 and 4, in the common area 11 of the two platforms of lines N1 and N2 on the third underground level, there is a second opening 30 in the middle of the station slab, which connects to the station hall on the second underground level. At least one of the second openings 30 corresponds to the first opening 31 in the slab to form the shared atrium 19 connecting the first to third underground levels. The atrium is 40m long and 30m wide. The other second opening 30 forms the shared atrium 190 between the second and third underground levels.

[0017] See Figure 3 , 4 As shown, the shared atrium architectural structure that integrates underground rail transit stations and urban spaces includes two sets of escalators and staircases at the east and west ends of the N1N2 line, connecting to the public areas of the platform.

[0018] See Figure 2 As shown, the shared atrium architectural structure integrating underground rail transit station and urban space includes a sunken courtyard space (24) on the north side of public area one (2) and public area two (3) that leads to the ground and descends to the second underground floor. The courtyard is 90m long and 18m wide, introducing the courtyard green landscape into the station. The sunken courtyard space from the first underground floor to the second underground floor is connected by stairs and escalators. Figure 5 The sunken courtyard space (24) on the second basement level can be reached through the shared atrium (19) or shared atrium one (190).

[0019] See Figure 1 , 2 As shown in Figure 4, the shared atrium architectural structure integrating underground rail transit stations and urban space comprises a shared atrium 19 formed by the opening 31 in the floor slab and the opening 30 in the middle slab of the west public area of ​​the N1 and N2 line station halls. This atrium integrates the platform, station hall, and the underground first-floor urban public commercial space 1. The shared atrium 19 has a width of two spans. The atrium's top is fitted with a flat glass roof, forming a horizontal glass roof 20, slightly higher than the outdoor ground level. Figure 5 Sunlight is introduced into the atrium roof, creating a complete, bright, and highly recognizable transfer and connection space.

[0020] The aforementioned shared atrium architectural structure integrating underground rail transit stations and urban space, wherein the N1 and N2 line concourse levels and the S1 line concourse level are located on the second underground level in an east-west direction, corresponding to the N1 and N2 line platform levels and the S1 line platform level on the third underground level, are described below. Figure 2 , 3 .

[0021] This invention integrates the design of underground urban space and rail transit structure, sharing a common column grid. The first underground level is the urban space, while the second and third underground levels are the rail transit station halls and platforms. In the station's public area, openings are made in the central floor slab of the second underground station hall, forming an atrium space between the hall and platform. Multiple openings are also made in the corresponding areas of the first underground urban space and the subway public area, forming another atrium space between them, thus creating a shared atrium space 19 connecting the first and third underground levels. The atrium is topped with a horizontal glass roof 20, extending into the ground-level green space.

[0022] The civil defense of the N1, N2, and N5 rail transit stations and the underground urban space is considered in a unified manner, while the S1 line is a subway station that also serves as a civil defense facility. The main structures of the N1, N2, and N5 lines and the underground urban space are verified according to the equivalent static load of nuclear level 6 and conventional level 6 civil defense to improve the overall resistance to destruction. For the equipment areas, mainly the equipment areas 4 and 7 on the concourse level and the equipment area 12 on the platform level, partial enclosure protection is carried out by setting up open walls 26 and protective equipment (27). The public areas are structurally reinforced and will not be used as personnel shelters in wartime. The N1, N2, and N5 lines and the S1 line are separated into civil defense zones by setting up open walls 26 and protective equipment (27) at the boundary of the concourse level.

[0023] The fire safety boundaries of the rail transit station and underground urban space are clearly defined. A fireproof roller shutter 21 separates the rail transit section from the underground urban space 1 at the shared atrium 19, ensuring that the centralized commercial or other urban functions of urban space 1 are separated from the fireproof roller shutter by a corridor 28. Smoke curtains 23 are installed at the boundary of the shared atrium 19 in the station hall and platform public areas 23. In case of fire, evacuation from the station platform and station hall is primarily through the entrances 25 and sunken courtyards 24 on the station hall level, while evacuation from the underground urban space is through the sunken courtyards 24. Natural smoke ventilation is achieved through the glass roof 20 in the main areas of the station, including the shared atrium 19.

[0024] Example The following is an explanation using specific engineering examples: This project is located in Island A of a new development zone. The Island A station hub is situated at the intersection of NB3 Road and EA3 Road in the core area of ​​Island A, where a large volume of passengers converges for transfers, making it a crucial node in the area. The rail transit station is a four-line interchange station connecting lines N1, N2, and N5 with the existing S1 line. Lines N1 and N2 are arranged east-west with S1, while line N5 is arranged north-south, forming an "I"-shaped interchange pattern. The surrounding area is planned for underground space development primarily for commercial functions, and an underground ring road is planned around the station to address traffic connectivity issues. This creates an integrated service space encompassing rail, roads, and pedestrian / bicycle transportation. The hub project serves as a vital transfer point for the rail network and road traffic, and a crucial transportation artery for the area, attracting a large passenger flow and providing high-quality services for passengers' travel and daily life—one of the most important functions of the hub design. By strengthening the integration of rail transit, underground public spaces, and surrounding land, an integrated underground station-city transportation hub on Island A is created, fostering seamless connectivity and promoting the overall prosperity and vitality of the area. The first basement level of Island A Station is the urban level. The second basement level is the concourse level for Line N5, and the concourse levels for Lines N1, N2, and S1, including the public area and equipment area for Line N5, and the public area, equipment area, and entrances / exits for Lines N1, N2, and the existing Line S1. The third basement level is the platform level for Lines N1, N2, and the existing Line S1, including the public area and equipment areas at both ends. Lines N1 and N2 are crucial components of the entire transportation hub's transfer axis. N1 and N2 are double-island flat-plan stations, with their concourse levels located on the second basement level, divided into east and west end concourses by the N5 track. The third basement level houses the platforms for Lines N1 and N2. An opening in the central slab connects the station's public area to the platform level. The opening is 40m long and 30m wide. Three sets of escalators and staircases are arranged in the paid area of ​​the station hall, two of which are four-step escalators to the second floor. They are positioned at both ends of the central slab opening, in line with the passenger flow. Smoke curtains 23 are installed at the bottom of the central slab opening, and 1.5N high enclosed fireproof glass railings 29 are installed at the central slab opening. The west end of the N1N2 line station hall is connected to the underground level and the urban public commercial space through an opening in the station hall roof slab. The opening in the roof slab is two spans wide, with smoke curtains 23 installed around it on the station hall level and a corridor 28 and fireproof roller shutters 21 on the underground level, ultimately forming a high atrium space that connects the platform to the underground urban public space. The atrium has a flat glass roof to allow sunlight to enter. The north side of the station hall is a sunken courtyard space that gradually rises, with a total length of 90m and a width of 18m. The courtyard's green landscape is incorporated into the station interior. This ultimately creates a complete, bright, and highly recognizable transfer space.
