Description

Technical Field

[0001] This invention relates to the field of underground and above-ground structures for rail transit, specifically to a green and intensive combined structure for subway entrances and ventilation shafts. Background Technology

[0002] Subway stations are typically built in urban areas with complex surrounding environments, high requirements for urban landscape, and stringent design specifications. Subway design specifications stipulate that when ventilation shafts are used for smoke extraction in emergency situations, the straight-line distance between the smoke extraction shaft opening and the air intake shaft opening or entrance / exit should ideally be greater than 10 meters. When site conditions limit the straight-line distance to less than 10 meters, an elevation difference arrangement can be used, but the smoke extraction shaft opening should ideally be 5 meters higher than the air intake shaft opening or entrance / exit, and the smoke extraction shaft must be higher than the air intake shaft. This ensures that smoke generated in emergency situations can be quickly and effectively extracted, preventing smoke from being drawn into the station or spreading through personnel entrances / exits, while also ensuring that fresh air can enter smoothly, creating conditions for evacuation and rescue.

[0003] However, subway stations are typically located in city centers where land resources are extremely scarce. Ensuring a strict 10-meter safety distance between all entrances and exits amidst dense building clusters and complex underground pipelines is challenging. Meeting the spacing requirements for above-ground buildings necessitates the addition of ventilation shafts and entrances, increasing the surface area occupied, the scale of underground civil engineering, and the overall workload.

[0004] Therefore, it is necessary to propose new measures to overcome the above-mentioned shortcomings. Summary of the Invention

[0005] The purpose of this invention is to provide a green and compact combined structure for subway entrances and ventilation shafts, which reduces the land area and construction costs while meeting the safety distance requirements between all entrances.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0007] A green and compact integrated construction structure for subway entrances and ventilation shafts is provided. The green and compact integrated construction structure includes an entrance passage above ground building and an underground space that are stacked vertically. The underground space is provided with an underground horizontal section and an underground climbing section of the entrance passage. The underground horizontal section of the entrance passage connects upward to the entrance passage above ground building through the underground climbing section.

[0008] The underground space is also equipped with an underground fresh air duct horizontal section, an underground exhaust air duct horizontal section, and an underground piston air duct horizontal section, all located on one side of the underground horizontal section of the entrance and exit passage.

[0009] The horizontal section of the underground fresh air duct connects to the vertical ventilation shaft of the underground fresh air duct and leads to the ground. The vertical ventilation shaft of the underground fresh air duct is located above the underground horizontal section of the entrance and exit passage.

[0010] The horizontal section of the underground ventilation duct connects to the vertical ventilation shaft of the underground ventilation duct and leads to the ground. The vertical ventilation shaft of the underground ventilation duct is located above the underground horizontal section of the entrance and exit passage.

[0011] The horizontal section of the underground piston ventilation duct is located below the underground climbing section of the entrance and exit passage, and connects to the vertical ventilation shaft of the underground piston ventilation duct and leads to the ground.

[0012] Furthermore, the underground horizontal section of the entrance / exit passage is located on the west side of the underground space, and the underground horizontal section of the entrance / exit passage is perpendicular to the underground ascending section of the entrance / exit passage, which is located on the north side of the underground space.

[0013] Furthermore, the underground fresh air duct horizontal section is located on the east side of the underground horizontal section of the entrance and exit passage and is adjacent to the underground horizontal section of the entrance and exit passage;

[0014] There are two vertical ventilation shafts in the underground fresh air duct, both located above the underground horizontal section of the entrance and exit passage, overlapping each other.

[0015] Furthermore, the horizontal section of the underground exhaust duct is located to the east of the horizontal section of the underground fresh air duct and is adjacent to the horizontal section of the underground fresh air duct.

[0016] There are two vertical ventilation shafts in the underground ventilation duct. One is located above the underground horizontal section of the entrance and exit passage, overlapping each other. The other is located above the underground climbing section of the entrance and exit passage, overlapping each other.

[0017] Furthermore, the horizontal section of the underground piston ventilation duct is located on the east side of the horizontal section of the underground exhaust ventilation duct, and two of them are arranged parallel to each other. Each horizontal section of the underground piston ventilation duct is connected to a vertical ventilation shaft of the underground piston ventilation duct.

[0018] Furthermore, the horizontal section of the underground piston ventilation duct is perpendicular to the underground climbing section of the entrance and exit passage, and passes through the underground climbing section of the entrance and exit passage from below.

[0019] Furthermore, the underground space is L-shaped in plan, and the underground piston ventilation shaft is located on the north side of the underground climbing section of the entrance and exit passage, that is, within the protruding part of the L-shaped underground space, and is located above the underground climbing section of the entrance and exit passage, overlapping each other.

[0020] Furthermore, the underground climbing section of the entrance and exit passage is equipped with a fire-resistant separation structure and an open structure at the exit of the entrance and exit passage from the ground building. The fire-resistant separation structure is located on the front and one side of the exit, and the open structure is located on the other side of the exit.

[0021] Furthermore, the open structure of the entrance / exit side faces away from the underground fresh air duct vertical shaft, the underground exhaust air duct vertical shaft, and the underground piston air duct vertical shaft.

[0022] Furthermore, a water collection pit is provided on the ground surface of the underground space.

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0024] This invention provides a green and compact integrated structure for subway entrances and ventilation shafts, featuring structural sharing. The underground spaces of the subway entrances and ventilation shafts are stacked, maximizing the efficient use of urban underground space. The stacked design allows the ventilation shafts and entrance / exit passages to share a common slab and external envelope, reducing construction steps and civil engineering costs. Furthermore, this invention designs a fire-resistant separation structure for the ground-level exits of the entrances and exits, fully utilizing the lateral space between the entrances and exits and reducing the relative distance between the ground-level buildings and the ventilation shafts. The compact design occupies a small area, further maximizing the use of urban above-ground space and minimizing the impact on urban space and landscape. Attached Figure Description

Detailed Implementation

[0031] To facilitate understanding of the present invention, a more complete description will be given below with reference to the accompanying drawings. Preferred embodiments of the invention are shown in the drawings. However, the invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a thorough and complete understanding of the disclosure of the invention.

[0032] In the description of this invention, it should be understood that the terms "east", "south", "west", "north", "up", "down", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0033] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "connection," "setting," etc., should be interpreted broadly. For example, they can refer to a fixed connection or setting, a detachable connection or setting, or an integral connection or setting. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0034] In a specific implementation, Figure 1 The top is defined as the north side, the bottom as the south side, the left as the west side, and the right as the east side. The directional descriptions of other attached diagrams are consistent with this.

[0035] This invention provides a green and compact integrated structure for subway entrances and ventilation shafts, in which the ventilation shafts and underground spaces are vertically stacked, resulting in a more concentrated space and meeting the regulatory requirements for safe distances between entrances.

[0036] Specifically, such as Figure 1 and Figure 2 The green and intensive integrated building structure includes an upper and lower stacked entrance passageway above ground building 8 and underground space.

[0037] The underground space includes a horizontal section 4 and an ascending section 4-1 for the entrance / exit passage. The horizontal section 4 is located on the west side of the underground space and runs north-south. The horizontal section 4 and the ascending section 4-1 are perpendicular to each other. The ascending section 4-1 is located on the north side of the underground space and runs east-west. The horizontal section 4 ascends through the ascending section 4-1 to connect to the surface building 8 and leads to the exit.

[0038] The underground space also includes three horizontal sections: an underground fresh air duct (section 5), an underground exhaust air duct (section 7), and an underground piston air duct (section 6). All are located on one side of the underground horizontal section 4 of the entrance / exit passage, within the angle between the underground horizontal section 4 and the underground ascending section 4-1 of the entrance / exit passage. All are oriented north-south and can accommodate axial flow fans and other necessary auxiliary equipment. The underground fresh air duct (section 5) is located east of and adjacent to the underground horizontal section 4 of the entrance / exit passage. The underground exhaust air duct (section 7) is located east of and adjacent to the underground fresh air duct (section 5). The underground piston air duct (section 6) is located east of the underground exhaust air duct (section 7), forming an integrated underground structural space.

[0039] The horizontal section 5 of the underground fresh air duct connects to the vertical ventilation shaft 1 of the underground fresh air duct and leads to the fresh air pavilion on the ground. The vertical ventilation shaft 1 of the underground fresh air duct is located above the horizontal section 4 of the entrance and exit passage. In addition, there are two vertical ventilation shafts 1 of the underground fresh air duct, both located above the horizontal section 4 of the entrance and exit passage, overlapping each other. The horizontal section 5 of the underground fresh air duct in the lower right of the figure enters directly into the vertical ventilation shaft 1 of the underground fresh air duct in the lower right of the figure through the air defense door. After the vertical ventilation shaft 1 of the underground fresh air duct extends out from the top plate of the ventilation shaft, it turns to the vertical ventilation shaft 1 of the underground fresh air duct in the upper left of the figure.

[0040] The horizontal section 7 of the underground ventilation duct connects to the vertical ventilation shaft 2 of the underground ventilation duct and leads to the ventilation pavilion on the ground. The vertical ventilation shaft 2 of the underground ventilation duct is located above the horizontal section 4 of the entrance passage. In addition, there are two vertical ventilation shafts 2 of the underground ventilation duct. One is located above the horizontal section 4 of the entrance passage, overlapping vertically. The other is located above the climbing section 4-1 of the entrance passage, overlapping vertically. The horizontal section 7 of the underground ventilation duct in the lower right of the figure enters the vertical ventilation shaft 2 of the underground ventilation duct in the lower right directly through the air-raid shelter door. After the vertical ventilation shaft 2 of the underground ventilation duct extends from the top plate of the ventilation shaft, it turns to the vertical ventilation shaft 2 of the underground ventilation duct in the upper left.

[0041] The horizontal section 6 of the underground piston ventilation duct is located below the underground climbing section 4-1 of the entrance / exit passage. It connects to the vertical ventilation shaft 3 of the underground piston ventilation duct and leads to the piston ventilation pavilion on the ground. Two sections are arranged parallel to each other, with each horizontal section 6 connecting to one vertical ventilation shaft 3. The horizontal section 6 of the underground piston ventilation duct is perpendicular to the underground climbing section 4-1 of the entrance / exit passage and passes underneath it.

[0042] from Figure 1 and Figure 3 It can be seen that the underground space is L-shaped in plan, with a protruding space on the north side near the east. The underground piston ventilation shaft 3 is located on the north side of the underground climbing section 4-1 of the entrance passage, that is, within the protruding part of the L-shaped underground space, and is located above the underground climbing section 4-1 of the entrance passage, overlapping each other.

[0043] like Figure 3 This application features a special design for the exit structure, ensuring that each exit is far apart from the others. The underground ascending section 4-1 of the entrance / exit passage includes a fire-resistant separation structure 9 and an open exit structure 10 (open door structure) at the exit of the entrance / exit passage from the ground-level building 8. The fire-resistant separation structure 9 is located on the front (east) and one side (north) of the exit, while the open exit structure 10 is located on the other side (south). This structural arrangement ensures that the open exit structure 10 faces away from the underground fresh air duct vertical shaft 1, the underground exhaust duct vertical shaft 2, and the underground piston duct vertical shaft 3, as the underground fresh air duct vertical shaft 1 and the underground exhaust duct vertical shaft 2 are both located on the west side of the exit, and the underground piston duct vertical shaft 3 is located on the north side of the exit. Furthermore, a road boundary line 11 can be installed outside the fire-resistant separation structure 9 to guide pedestrian flow through the open exit structure 10. Compared to traditional standard entrance and exit buildings, this invention adopts an entrance and exit with lateral passenger flow, optimizes the open area near the piston ventilation shaft into a fireproof structure, makes full use of the lateral space of the entrance and exit to meet the 10m spacing required by the regulations, reduces the relative distance between the entrance / exit building and the piston ventilation shaft, and can also make intensive use of urban ground space.

[0044] In addition, a water collection pit 12 is set on the ground surface of the underground space, such as... Figure 2 It can be located in the underground horizontal section 4 of the entrance and exit passage, between the underground fresh air duct horizontal section 5 and the underground exhaust air duct horizontal section 7, and in the underground piston air duct horizontal section 6, and can be set in a north-south direction.

[0045] The green and intensive integrated construction structure of this invention maximizes the use of urban underground and above-ground space. The stacked design of subway ventilation shafts and entrance / exit passages minimizes the amount of civil engineering work attached to subway stations and the impact on urban space and landscape. It reduces unnecessary engineering investment. Based on the functional use of subway ventilation shafts and entrances / exits, it integrates the spatial relationship between the two, which can meet the functional requirements while making efficient use of urban land. The design is compact, occupies less land, has low construction costs, and is easy to promote.

[0046] The above examples illustrate the present invention only to aid in understanding it and are not intended to limit the scope of the invention. Those skilled in the art can make various simple deductions, modifications, or substitutions based on the principles of this invention.
