Abstract

Technical Field
[0001] This application relates to the field of tunnel engineering technology, and in particular to a track-top ventilation duct component and a subway station structure. Background Technology
[0002] In related technologies, construction joints are located within the rail top ventilation duct. Since construction joints are weak points for water leakage, and the space in the rail top ventilation duct is narrow, if water leaks through this construction joint, the water will flow into the rail top ventilation duct through the side wall along the construction joint, which is difficult to control. This will have a certain impact on the operation of trains after the station is put into operation. Moreover, after the station is put into operation, workers will face great safety hazards when working in the limited space of the rail top ventilation duct, making it difficult to find leakage points and impossible to carry out targeted grouting to stop water leakage, thus increasing maintenance costs.

The rail-top air duct bottom plate is integrally formed with the rail-top air duct middle plate and is connected to the rail-top air duct middle plate. One end of the rail-top air duct bottom plate is connected to the outer periphery of the rail-top air duct sidewall, and the other end extends obliquely towards the rail-top air duct middle plate. The cavity formed between the rail-top air duct sidewall, the rail-top air duct top plate, the rail-top air duct bottom plate, and the rail-top air duct middle plate is the rail-top air duct.
[0006] According to the embodiments of this application, by setting the connection point between the bottom plate of the rail top ventilation duct and the side wall of the rail top ventilation duct on the outer circumferential surface of the side wall of the rail top ventilation duct, the original horizontal construction joint can be transformed into a vertical construction joint, which helps to reduce the leakage problem of the rail top ventilation duct component, thereby preventing water from flowing into the rail top ventilation duct along the construction joint, and also facilitating inspection and treatment, thereby helping to reduce maintenance costs.

The first fixing segment has a plurality of snap-fit holes, and the snap-fit member is connected to the second fixing segment and is used to engage with the snap-fit holes.
[0013] In one possible implementation, the fixing bracket further includes a second fixing ring disposed at the end of the fixing rod away from the first fixing ring, the second fixing ring forming a second fixing opening, through which the sealing member passes.
[0014] In one possible implementation, the fixing rod is a telescopic member.
[0015] Secondly, this application provides a subway station structure, including a station roof slab, a first side wall, a second side wall, a station floor slab, and the aforementioned rail-top ventilation duct assembly.

Furthermore, the directional terms mentioned in the embodiments of this application, such as "inner" and "outer," are only for reference to the directions in the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of this application, and are not intended to 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 limitations on the embodiments of this application.

Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.
[0034] In related technologies, construction joints are located within the rail top ventilation duct. Since construction joints are weak points for water leakage, and the space in the rail top ventilation duct is narrow, if water leaks through this construction joint, the water will flow into the rail top ventilation duct through the side wall along the construction joint, which is difficult to control. This will have a certain impact on the operation of trains after the station is put into operation. Moreover, after the station is put into operation, workers will face great safety hazards when working in the limited space of the rail top ventilation duct, making it difficult to find leakage points and impossible to carry out targeted grouting to stop water leakage, thus increasing maintenance costs.
[0035] To address the aforementioned technical problems, this application provides a track-top ventilation duct assembly and a subway station structure.
[0036] The track-top air duct assembly of this application embodiment will be described below.
[0037] Please see Figure 1 , Figure 1This is a schematic diagram of a subway station structure provided in some embodiments of this application. The track top ventilation duct assembly 5 may include: a track top ventilation duct sidewall 51, a track top ventilation duct top plate 52, a track top ventilation duct bottom plate 53, and a track top ventilation duct middle plate 54. The cavity formed between the track top ventilation duct sidewall 51, the track top ventilation duct top plate 52, the track top ventilation duct bottom plate 53, and the track top ventilation duct middle plate 54 is the track top ventilation duct.
[0038] The top plate 52 of the rail-top ventilation duct extends from the outer periphery of the rail-top ventilation duct sidewall 51 in a direction away from the rail-top ventilation duct sidewall 51, and is integrally formed with the rail-top ventilation duct sidewall 51. This arrangement helps to improve the construction efficiency of the rail-top ventilation duct assembly 5.
[0039] The bottom plate 53 of the rail-top ventilation duct and the middle plate 54 of the rail-top ventilation duct are integrally formed. This arrangement helps to improve the construction efficiency of the rail-top ventilation duct assembly 5.
[0040] The top plate 52 of the rail-top ventilation duct is connected to the middle plate 54 of the rail-top ventilation duct. One end of the bottom plate 53 of the rail-top ventilation duct is connected to the outer peripheral surface of the side wall 51 of the rail-top ventilation duct, and the other end extends inclined towards the middle plate 54 of the rail-top ventilation duct. Specifically, the connection point between the bottom plate 53 and the side wall 51 of the rail-top ventilation duct is located on the outer peripheral surface of the side wall 51. This allows the construction joint between the bottom plate 53 and the side wall 51 to be a vertical construction joint, which helps reduce water seepage and facilitates inspection and remediation.
[0041] According to the embodiment of this application, the rail top ventilation duct assembly 5 can be transformed into a vertical construction joint by setting the connection point between the rail top ventilation duct base plate 53 and the rail top ventilation duct side wall 51 on the outer circumferential surface of the rail top ventilation duct side wall 51. This helps to reduce the leakage problem of the rail top ventilation duct assembly 5, thereby preventing water from flowing into the rail top ventilation duct along the construction joint. It also facilitates inspection and treatment, thereby helping to reduce maintenance costs.
[0042] Please continue reading. Figure 1 In some embodiments, there is a gap between the bottom plate 53 of the rail-top ventilation duct and the bottom surface of the side wall 51 of the rail-top ventilation duct. This allows for better detection and quality control of leaks, thereby helping to reduce maintenance costs.
[0043] Please continue reading. Figure 1 In some embodiments, the distance between the bottom plate 53 of the rail top duct and the bottom surface of the side wall 51 of the rail top duct is greater than or equal to 300cm and less than or equal to 500cm. For example, the distance between the bottom plate 53 of the rail top duct and the bottom surface of the side wall 51 of the rail top duct can be 300cm, 320cm, 340cm, 360cm, 380cm, 400cm, 420cm, 440cm, 460cm, 480cm, 490cm, 500cm, etc.
[0044] Therefore, by limiting the distance between the bottom plate 53 of the rail top air duct and the bottom surface of the side wall 51 of the rail top air duct, the problem of water leakage of the rail top air duct assembly 5 can be better reduced.
[0045] Please see Figure 1 and Figure 2 , Figure 2 This is a schematic diagram of the sealing component connection provided in some embodiments of this application. In some embodiments, a sealing component 55 is provided at the connection between the bottom plate 53 of the rail top ventilation duct and the side wall 51 of the rail top ventilation duct. This prevents concrete from flowing into the side wall 51 of the rail top ventilation duct, thereby solving the quality problem of easy mixing of different grades of concrete at the junction of the plate and the wall, and thus helping to improve the structural strength of the rail top ventilation duct assembly 5.
[0046] Please continue reading. Figure 1 and Figure 2 In some embodiments, the sealing element 55 is an isolation airbag. This facilitates the installation of the sealing element 55 and reduces its usage cost, thereby helping to reduce the construction cost of the rail-top ventilation duct assembly 5.
[0047] Please see Figure 2 and Figure 3 , Figure 3 This is a schematic diagram of a fixed bracket provided in some embodiments of this application. In some embodiments, the rail-top ventilation duct assembly 5 may further include a fixed bracket 6. The fixed bracket 6 may include a fixed rod 61, a fixed hook 62, and a first fixed ring 63. The fixed hook 62 is rotatably disposed at one end of the fixed rod 61, and the rotation direction of the fixed hook 62 is perpendicular to the extension direction of the fixed rod 61. Specifically, by providing the fixed hook 62, it is convenient to cooperate with the steel reinforcement support on the construction site. At the same time, the rotatable form makes it convenient for construction personnel to assemble according to the actual construction situation, thereby improving the user experience.
[0048] A first fixing ring 63 is disposed at the other end of the fixing rod 61, forming a first fixing opening through which the sealing member 55 passes. Specifically, when supporting the sealing member 55, the fixing rod 61 is first fixed by the fixing hook 62, then the sealing member 55 is moved through the first fixing ring 63 to one end of the fixing rod 61, and finally the end of the sealing member 55 is supported by the first fixing ring 63 to prevent the sealing member 55 from tilting. Thus, this arrangement allows the sealing member 55 to be supported by the first fixing ring 63, enabling it to better perform its isolation function.
[0049] Please continue reading. Figure 2 and Figure 3In some embodiments, the first fixing ring 63 may include a first fixing segment 631, a second fixing segment 632, and a snap-fit member 633. The first fixing segment 631 has a plurality of snap-fit holes 6311, and the snap-fit member 633 is connected to the second fixing segment 632 and is used to snap into the snap-fit holes 6311. The plurality of snap-fit holes 6311 may be spaced apart along the extending direction of the first fixing segment 631. Thus, by the cooperation between the plurality of snap-fit holes 6311 and the snap-fit member 633, the size of the first fixing opening can be changed, allowing the first fixing ring 63 to accommodate more sealing members 55 of different sizes, thereby improving the versatility of the fixing bracket 6.
[0050] Please continue reading. Figure 2 and Figure 3 In some embodiments, the fixing bracket 6 may further include a second fixing ring 64. The second fixing ring 64 is disposed at the end of the fixing rod 61 away from the first fixing ring 63, and the second fixing ring 64 forms a second fixing opening through which the sealing member 55 passes. Thus, the first fixing ring 63 and the second fixing ring 64 can limit the two ends of the sealing member 55, thereby allowing the fixing bracket 6 to better support the sealing member 55, which in turn improves the fixing effect of the fixing bracket 6.
[0051] Please continue reading. Figure 2 and Figure 3 In some embodiments, the fixing rod 61 is a telescopic component. The telescopic nature of the fixing rod 61 can be achieved by connecting multiple movable rod segments. This arrangement allows the fixing rod 61 to better accommodate sealing components 55 of different sizes, thereby improving the versatility of the fixing bracket 6.
[0052] The subway station structure 100 of this application embodiment will be described below.
[0053] The subway station structure 100 of this application embodiment includes a station roof slab 1, a first side wall 2, a second side wall 3, a station floor slab 4, and the aforementioned rail-top ventilation duct assembly 5. The station roof slab 1 is connected to the rail-top ventilation duct side wall 51 via the first side wall 2, and the station floor slab 4 is connected to the rail-top ventilation duct side wall 51 via the second side wall 3. This helps reduce water leakage problems in the rail-top ventilation duct assembly 5, thereby preventing water from flowing into the rail-top ventilation duct along construction joints. It also facilitates inspection and remediation, thus reducing maintenance costs.
[0054] In the description of this specification, specific features, structures, materials, or characteristics may be combined in any suitable manner in one or more embodiments or examples.
[0055] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
