Description

Technical Field

[0001] This utility model relates to the technical field of subway station structures, and in particular to an irregularly shaped station with continuous openings in the side walls that also accommodates level crossing transitions. Background Technology

[0002] Subway stations are typically used as civil defense projects. When a two-story station with three turnouts is built deep, the station's net width can reach over 30 meters. The conventional approach is a double-column, three-span scheme with a flat roof and straight structural columns. However, for a three-turnout station that straddles the road boundary, the above scheme has the following shortcomings:

[0003] 1. The double-column structure has significant limitations on space and obstructs the view, which greatly affects the functional layout of the building;

[0004] 2. The pipeline burial depth on the station roof is inconsistent. The station roof within the road area is made of flat material, which cannot make full use of the soil cover space.

[0005] 3. The station is located underground, and the station view and lighting are poor. The space for soil covering on the station roof within the road red line has not been fully utilized.

[0006] 4. When there are continuous openings in the side walls of the station, the civil defense sealing installation requires a lot of building space, and when there is a sunken plaza, the station will have a large lateral deformation. Summary of the Invention

[0007] The purpose of this utility model is to address the shortcomings of the existing technology by providing an irregularly shaped station with continuous openings in the side walls that also accommodates level-station transitions. The station roof slab of this irregularly shaped station consists of a flat plate and an inclined plate, and is supported by irregularly shaped columns on the first underground floor of the station, meeting the needs of large spans, high clearance, and the placement of pipelines at different burial depths. The continuous openings in the side walls, with horizontally sliding sealing plates, meet civil defense requirements and reduce building space occupation. The station roof slab within the road red line is raised to increase the station's clearance and openness. The underground walls on the non-sunken plaza side adopt T-shaped underground walls to increase the station's rigidity and reduce lateral deformation of the station under continuous openings in the side walls.

[0008] The objective of this utility model is achieved through the following technical solution:

[0009] An irregularly shaped station with continuous openings in the side walls to accommodate level crossings, the station includes a station roof slab, a station center slab, a station floor slab, irregularly shaped columns on the first basement level, a center column on the second basement level, and station side walls. The station roof slab, center slab, and floor slab are all connected to the station side walls. The station roof slab is composed of a flat plate and an inclined plate, with one side of the inclined plate connected to the flat plate and the other side sloping downwards. The irregularly shaped columns on the first basement level are wavy, with the crests connecting to the connection between the flat plate and the inclined plate, and the troughs connecting to... The top of the station's central slab is connected; the underground level of the irregular-shaped station is connected to the sunken plaza through doorways, and multiple doorways are provided along the longitudinal direction; the station's side walls are divided into thickened side walls on the non-sunken plaza side away from the sunken plaza and sunken plaza side walls on the sunken plaza side close to the sunken plaza. The outer side of the thickened side wall on the non-sunken plaza side is provided with a T-shaped underground wall on the non-sunken plaza side. The top side of the T-shaped underground wall on the non-sunken plaza side is at the same height as the low side of the inclined slab. The T-shaped underground wall on the non-sunken plaza side is composed of a longitudinal wall and several transverse walls connected to the longitudinal wall.

[0010] The lateral length of the inclined plate is greater than the lateral length of the flat plate.

[0011] An underground wall for the sunken plaza is provided on the outer side of the side wall of the sunken plaza.

[0013] The two ends of the central column on the second underground floor of the station are connected to the bottom of the central slab and the top of the station floor slab, respectively. Multiple central columns are provided longitudinally on the second underground floor of the station. The top of the central column is connected to the bottom of the central slab through the longitudinal beam of the central slab, and the bottom of the central column is connected to the top of the station floor slab through the longitudinal beam of the floor slab.

[0014] The bottom of the station's base slab is connected to engineering piles.

[0015] A horizontal sliding sealing plate is provided at the doorway for sealing the doorway, and the horizontal sliding sealing plate is installed inside the concealed doorway.

[0026] The features and other related features of this utility model will be further described in detail below with reference to the accompanying drawings and embodiments, so as to facilitate the understanding of those skilled in the art:

[0027] Example: Figures 1-3As shown, this embodiment relates to an irregularly shaped station with continuous openings in the side walls that also accommodate level crossings. This irregularly shaped station mainly includes a station roof slab 1, a station middle slab 10, a station floor slab 15, irregularly shaped columns 7 on the first basement level, a middle column 14 on the second basement level, and station side walls. The station roof slab 1, station middle slab 10, and station floor slab 15 are all connected to the station side walls. The first basement level of the irregularly shaped station is connected to a sunken plaza 5 through doorways 6, and multiple doorways 6 are provided longitudinally. The station side walls are divided into non-sunken sections located away from the sunken plaza 5. The sunken plaza side wall 8 is thickened and the sunken plaza side wall 13 is set near the sunken plaza 5. The sunken plaza side underground wall 12 of the sunken plaza 5 is connected to the sunken plaza side wall 13. That is, a doorway 6 is opened on the sunken plaza side underground wall 12 and the sunken plaza side wall 13. The thickness of the sunken plaza side underground wall 12 is greater than the thickness of the sunken plaza side wall 13, and the bottom of the sunken plaza side underground wall 12 is located below the station floor slab 15. The floor slab of the sunken plaza 5 is located between the station middle slab 10 and the station floor slab 15. The station roof slab 1 consists of a flat plate and an inclined plate. The flat plate and the inclined plate are respectively located on both sides of the road red line 18. One side of the inclined plate is connected to the flat plate, and the other side is inclined downward. That is, the high side of the inclined plate is connected to the flat plate, and the low side of the inclined plate is connected to the station side wall (the thickened side wall 8 on the non-sunken plaza side). The lateral length of the inclined plate is greater than the lateral length of the flat plate. That is, with the road red line 18 as the dividing line, the side of the station away from the sunken plaza 5 is the large span side, and the side of the station closer to the sunken plaza 5 is the non-large span side. The station roof slab 1 is covered with soil of different thicknesses to meet the needs of pipelines at different burial depths. The two ends of the central column 14 on the second underground floor of the station are connected to the bottom of the central slab 10 and the top of the station floor slab 15, respectively. There are multiple central columns 14 on the second underground floor of the station along the longitudinal direction. The top of the central column 14 on the second underground floor of the station is connected to the bottom of the central slab 10 through the longitudinal beam 11 of the central slab. The bottom of the central column 14 on the second underground floor of the station is connected to the top of the station floor slab 15 through the longitudinal beam 16 of the floor slab. The bottom of the station floor slab 15 is connected to the engineering piles 17. The engineering piles 17 located on the large span side of the station need to be densely arranged, and the engineering piles 17 located on the non-large span side of the station can be spaced further apart, which can improve the stress on the station floor slab 15 and the lateral deformation of the station.

[0028] like Figure 1 and Figure 3As shown, the irregularly shaped column 7 on the first basement level of the station is wavy. The crest of the irregularly shaped column 7 connects to the joint between the flat plate and the inclined plate, and the trough connects to the top of the station's central slab 10. The crest of the irregularly shaped column 7 on the first basement level of the station is connected to the station's roof slab 1 through the longitudinal beam 2 of the roof slab. The trough of the irregularly shaped column 7 on the first basement level of the station is located directly above the central column 14 on the second basement level of the station. Compared with straight columns, the wavy irregularly shaped column 7 on the first basement level of the station can improve seismic performance and ductility (energy absorption and dissipation, reducing seismic force transmission), improve load distribution and reduce stress concentration (uniformly disperse loads, adapting to uneven settlement), optimize space utilization and functional integration (providing equipment installation space, enhancing ventilation and visual effects), and improve structural toughness and durability (enhanced fatigue resistance, high material efficiency).

[0029] like Figure 1 As shown, the thickness of the thickened side wall 8 on the non-sunken plaza side is greater than the thickness of the side wall 13 on the sunken plaza side. A T-shaped underground wall 9 on the non-sunken plaza side is provided on the outside of the thickened side wall 8 on the non-sunken plaza side. The T-shaped underground wall 9 on the non-sunken plaza side consists of a longitudinal wall and several transverse walls connected to the longitudinal wall. The top side of the T-shaped underground wall 9 on the non-sunken plaza side is at the same height as the bottom side of the inclined plate. By using the thickened side wall 8 on the non-sunken plaza side and the T-shaped underground wall 9 on the non-sunken plaza side, the lateral load of the station can be solved and the lateral deformation of the station can be reduced.

[0030] like Figure 1 and Figure 2 As shown, a horizontal sliding sealing plate 3 is provided at the doorway 6 to seal the doorway 6. The horizontal sliding sealing plate 3 is installed inside the concealed doorway 4. The horizontal sliding sealing plate 3 is a telescopic structure and can move horizontally. During normal use, the doorway 6 is open and the horizontal sliding sealing plate 3 is located inside the concealed doorway 4. During wartime use, the horizontal sliding sealing plate 3 is pushed and pulled to the doorway 6 to seal it.

[0031] The beneficial technical effects of this embodiment are as follows:

[0032] 1. The station roof is raised by using sloping slabs to increase the clearance height, thereby increasing the station's openness;

[0033] 2. Different thicknesses of soil are used on the roof of the station to meet the needs of pipelines at different burial depths;

[0034] 3. Horizontal sliding sealing plates are used to solve the problem of continuous openings in the side walls occupying a large amount of building area for defense;

[0035] 4. Increase the thickness of the side wall and install a T-shaped underground wall on the side not under the sunken plaza to solve the problem of lateral load on the station and reduce the lateral deformation of the station.

[0036] Although the above embodiments have described the concept and embodiments of the present invention in detail with reference to the accompanying drawings, those skilled in the art will recognize that various improvements and modifications can still be made to the present invention without departing from the scope of the claims, and therefore will not be elaborated here.
