Description

Technical Field

[0001] This utility model belongs to the field of subway station technology, specifically relating to a rectangular cross-section combined subway station. Background Technology

[0002] In urban centers, the surface is often densely packed with various buildings and structures, while underground, a multitude of pipelines are also laid out. In the central areas of old city districts, roads are narrow and traffic is heavy. Coupled with road boundary restrictions, traditional cut-and-cover methods for subway station construction present multiple challenges, including difficulties in demolition (or prohibitions on demolition), stringent implementation conditions, high construction risks, difficulties in controlling the construction period, and high upfront demolition costs. Therefore, exploring a new construction method that requires less land, involves less demolition, has less environmental impact, allows for controllable construction periods, carries lower risks, and is more economical is of great significance for subway station construction in urban centers, especially in the central areas of old city districts.

[0003] Furthermore, the relatively limited cross-sectional size of commonly used rectangular tunnel boring machines (TBMs) or pipe jacking systems makes it difficult to meet the functional and architectural layout requirements of subway stations. At the same time, ultra-large rectangular TBMs or pipe jacking systems still present numerous technical challenges and high costs in equipment manufacturing and on-site implementation. Therefore, researching how to achieve subway station functionality through combinations of rectangular cross-sections of existing TBMs or pipe jacking systems will provide an innovative approach to the construction of subway stations using cut-and-cover methods in the complex environments of central urban areas.

[0016] A type of rectangular cross-section double-hole combined subway station, such as Figure 1-7 As shown, the subway station includes two parallel rectangular pipe jacking tunnels, 1a and 1b, at the same elevation. Tunnel 1a and 1b have identical cross-sectional dimensions and are interconnected via end shafts 2 at both ends. The end shafts 2 connect to the station entrance / exit 4 at ground level via access passages 3, used for passengers and staff to enter the station. Access passages 3 have a turnstile system 5 installed at one end near the end shafts 2. Automatic ticket vending machines 6 and security screening machines 7 are located between the station entrance / exit 4 and the turnstile system 5. Platforms 12 are located on one side of both rectangular pipe jacking tunnels 1a and 1b, and a train track 11 is located on the other side.

[0017] The access control system 5 includes turnstiles that open automatically by swiping a QR code or metro card, and a barrier device located on one side of the turnstiles for manual opening in case of turnstile malfunction or other needs. Furthermore, the staircases and / or elevators (including escalators and elevators) at each entrance / exit and end shaft 2, as well as ventilation shafts within end shaft 2 and other related facilities and equipment such as track-top ventilation ducts within the tunnel, can all be conventionally installed and will not be described in detail in this embodiment or the following embodiments.

[0018] This utility model for subway stations connects two parallel rectangular pipe jacking tunnels at the same elevation at an end shaft. The end shaft is connected to the station entrance / exit via an access passage. An access gate system is installed at the end of the access passage near the end shaft. This utility model eliminates the need for a concourse level in conventional subway stations, simplifying the station structure while still effectively meeting the station's technical and functional requirements. It is highly feasible, low-risk, and can be completed quickly. It provides a new approach to subway station construction in central urban areas, reducing pipeline relocation, minimizing disturbance to residents, optimizing traffic flow, and offering good economic benefits.

[0019] As a preferred embodiment, the pipe jacking segments of the No. 1 rectangular pipe jacking tunnel 1a and the No. 2 rectangular pipe jacking tunnel 1b are pre-embedded and fixed with pre-embedded steel plates 13 by welding studs on the inner wall of the platform 12. The outer surface of the pre-embedded steel plates 13 is welded with steel beams 14 or steel brackets 15. One end of the platform slab of the platform 12 is erected and fixed on the steel beams 14 or steel brackets 15, and the other end of the platform slab of the platform 12 is fixedly installed on the inner bottom surface of the pipe jacking segment by the support legs.

[0020] This utility model of a subway station achieves rapid and modular platform construction by pre-embedding steel plates in the inner wall of the tunnel jacking segments and welding steel beams or steel brackets to one side of the platform slab, thereby saving labor and improving construction efficiency.

[0021] Preferably, the train tracks 11 and platform 12 in the first rectangular pipe jacking tunnel 1a are symmetrically arranged with the train tracks 11 and platform 12 in the second rectangular pipe jacking tunnel 1b, with the train tracks 11 closer to the inner side and the platform 12 closer to the outer side. Safety doors are provided on the tunnel sidewalls of both the first rectangular pipe jacking tunnel 1a and the second rectangular pipe jacking tunnel 1b, and are connected to safety passages 9 leading to safety openings 8 at the ground level.

[0022] This utility model ensures that in the event of an accident, staff and passengers can quickly evacuate through the safety passage by setting the platform at the outer end of the tunnel and connecting it to the safety opening at ground level via a safety passage. Example 2

[0023] A type of rectangular cross-section three-hole combined subway station, such as Figure 8-13As shown, the subway station is mainly constructed from three rectangular pipe jacking tunnels of the same size arranged in a triangular pattern. The three rectangular pipe jacking tunnels are interconnected through end shafts 2 at both ends. The upper rectangular pipe jacking tunnel 1c is located at the station concourse level, while the lower rectangular pipe jacking tunnels 1a and 2b are located at the platform level. The end shafts 2 connect to the station entrances 4 at ground level via access passages 3. An access gate system 5 is installed at one end of the access passages 3 near the end shafts 2. Automatic ticket vending machines 6 and security screening machines 7 are installed between the station entrances 4 and the access gate system 5. The train tracks 11 and platform 12 in rectangular pipe jacking tunnel 1a are symmetrically arranged with those in rectangular pipe jacking tunnel 1b. The arrangement of train tracks 11 and platform 12 can be the same as in Embodiment 1, with train tracks 11 arranged closer to the inside and platform 12 arranged closer to the outside. Preferably, in this embodiment, the arrangement of the train track 11 and platform 12 differs from that in Embodiment 1. In this embodiment, the train track 11 is closer to the outer side, and the platform 12 is closer to the inner side. To facilitate passengers who go the wrong way and transfer in the opposite direction, the No. 1 rectangular pipe jacking tunnel 1a and the No. 2 rectangular pipe jacking tunnel 1b are also interconnected by several connecting channels 10 distributed at intervals along the length direction. The inner walls of both sides of the pipe jacking segment of the No. 3 rectangular pipe jacking tunnel 1c are pre-embedded with steel plates 13 by welding studs. The outer surface of the pre-embedded steel plates 13 is welded with steel beams 14 or steel brackets 15. The two ends of the station slab of the concourse level are erected and fixed on the steel beams 14 or steel brackets 15, and the middle part of the station slab is fixed to the inner bottom surface of the pipe jacking segment by the support legs.

[0024] As a preferred option, depending on actual needs or the existing road structure, the two sides of the No. 3 rectangular pipe jacking tunnel 1c are also connected to the central station entrance 4 through the central access passage 3. The central access passage 3 is also equipped with the station entrance and exit gate system 5, security check machine 7 and automatic ticket vending machine 6.

[0025] This utility model constructs a combined three-tunnel subway station based on three independent rectangular cross-section pipe jacking tunnels arranged in a triangular pattern. In actual implementation, conventional shield tunneling or pipe jacking equipment can be used to complete the main tunnel construction. It is highly feasible, low-risk, and can be completed quickly in the complex environment of the central urban area. It also effectively meets the full functions of a conventional station. The two reverse traffic tracks are all unidirectional single-tunnel traffic, and the two tunnels are partially connected in the middle, which also reduces the construction risk of bidirectional full connection and lowers the construction cost.

[0026] This utility model is not limited to the specific embodiments described above. For those skilled in the art, all modifications made based on the above concept without creative effort fall within the protection scope of this utility model.
