Description
Technical Field
[0001] This utility model belongs to the field of bridge engineering technology, specifically relating to an integrated beam-track high-speed maglev track beam evacuation platform and a high-speed maglev track beam with the evacuation platform. Background Technology
[0002] For high-speed railway bridge structures, fixed-point evacuation is mainly adopted, that is, a maintenance passage is set up at regular intervals along the line, which also serves as a rescue and escape passage. For urban rail transit, due to the diversity of systems and beam types, the evacuation and rescue modes vary, but generally they fall into five categories: train self-rescue, longitudinal coupling evacuation and rescue, lateral rescue, evacuation passage rescue, and vertical rescue.
[0003] For medium- and low-speed maglev transportation, there are three main beam types (two categories) in existing or under-construction medium- and low-speed maglev projects both domestically and internationally. The first is the most widely used parallel single-track box girder scheme (integrated beam and track), which is used in both the Japanese maglev and the Changsha maglev in China. The second is the "beam-on-beam" double-track box girder scheme (beam-on-beam), which is used in the Beijing S1 line. The third is the parallel single-track U-beam scheme (beam-on-beam) used by the Phoenix maglev. The evacuation and rescue methods differ for each of these three beam types.
[0004] In the "beam-on-beam" double-track box girder and parallel single-track U-beam schemes, evacuation passages are located in the middle of the structure. Due to structural limitations, direct evacuation to the ground is not possible via the evacuation structure. For medium-low speed maglev bridges using this type of bridge structure, evacuation and rescue primarily occur through these passages to the station. The parallel single-box girder scheme features a hollow structure with evacuation passages located on the crossbeams, allowing for the construction of underground evacuation routes. Therefore, this structure employs a fixed-point rescue scheme similar to high-speed railways, with maintenance passages leading to the ground from the evacuation passages at regular intervals along the line, also serving as rescue escape routes. The underground maintenance passages are primarily composed of gently sloping pedestrian stairs.
[0005] However, there is still a lack of existing integrated beam-track high-speed maglev track beam evacuation platform structures, and there is an urgent need to design an emergency rescue platform facility that is compatible with high-speed maglev lines. Utility Model Content
[0006] In response to one or more of the above-mentioned defects or improvement needs of the existing technology, this utility model provides an integrated beam-track high-speed maglev track beam evacuation platform and track beam, which is suitable for situations where the station spacing of high-speed maglev railway is large. In an emergency, passengers can quickly evacuate to the ground via stairs, greatly reducing the time required for escape.
[0007] To achieve the above objectives, according to one aspect of the present invention, a beam-track integrated high-speed maglev track beam evacuation platform is provided, comprising a concrete beam evacuation platform longitudinally arranged on the side of the track beam;
[0008] The concrete beam evacuation platform is equipped with a platform slab, and the platform slab is connected to the ground via a staircase;
[0009] In a single-track line, the concrete beam evacuation platform is set on the cantilever T-shaped pier used to support the track beam. The cantilever T-shaped pier has a cantilever extending outward along one side in the lateral direction. The concrete beam evacuation platform is set on the top of the cantilever, and the platform plate corresponds to the lower outer side of the high-speed maglev train in the lateral direction.
[0010] In the double-track line, the concrete beam evacuation platform is located on top of the π-shaped pier used to support the track beams and is situated between the track beams of the double track; the platform plate is located below the high-speed maglev trains of the double track.
[0011] As a further improvement of this utility model, in a single-line circuit, railings are provided on both sides of the platform plate in the horizontal direction; a pipe for laying cables is buried under the platform plate, or a pipe for laying cables is installed on the railings.
[0012] As a further improvement of this utility model, in the dual-line circuit, a pipe for laying cables is buried under the platform plate.
[0013] As a further improvement of this utility model, in the double-track line, the concrete beam evacuation platform is connected to the inner side of the track beam of the double track on both sides, and the bottom does not contact the π-shaped pier, so that the concrete beam evacuation platform and the track beam form an integrated structure.
[0014] As a further improvement of this utility model, the evacuation platform is located outside the building clearance of the high-speed maglev railway, and the height of the concrete beam evacuation platform, platform slab and railing is lower than the building clearance.
[0015] As a further improvement of this utility model, the concrete beam evacuation platform gradually thickens from the end to the middle at intervals along the longitudinal direction, with the thickness being the greatest at the location where the stairs are set.
[0016] As a further improvement of this utility model, the concrete beam evacuation platform and the platform plate are arranged along the longitudinal direction.
[0017] As a further improvement of this utility model, the height of the concrete beam evacuation platform is lower than that of the track beam.
[0018] According to a second aspect of this utility model, a beam-track integrated high-speed maglev track beam with an evacuation platform is provided. The beam-track integrated high-speed maglev track beam includes a cantilever T-shaped pier for supporting the top track beam. The cantilever T-shaped pier has a cantilever extending outward along one transverse side. A concrete beam evacuation platform is provided at the top of the cantilever, which is longitudinally arranged on the side of the track beam. A platform slab is provided on the concrete beam evacuation platform, and the platform slab corresponds transversely to the lower outer side of the high-speed maglev train. The platform slab is connected to the ground via a staircase. Alternatively...
[0019] The integrated beam-track high-speed maglev track beam includes a π-shaped pier for supporting the double-track track beam. A concrete beam evacuation platform is provided longitudinally between the track beams, and the two sides of the concrete beam evacuation platform are respectively connected to the inner side of the double-track track beam. A platform plate is provided longitudinally in the middle of the concrete beam evacuation platform. The platform plate is located below the double-track high-speed maglev train and is connected to the ground through a staircase.
[0020] In summary, the technical solutions conceived by this utility model have the following beneficial effects compared with the prior art:
[0021] (1) The beam-track integrated high-speed maglev track beam evacuation platform of this utility model, by setting up an evacuation platform and escape stairs, allows passengers to walk directly to the location of the escape stairs after an accident, and walk to the ground in an orderly manner under the organization of staff. The distance between high-speed maglev railway stations is large, and it takes a long time to walk to the nearest station. The setting of escape stairs can eliminate the need for passengers to walk to the nearest station, greatly reducing the time required for escape, enabling passengers to quickly evacuate to a safe area in an emergency, effectively reducing the possibility of accidents and maximizing the safety of passengers' lives.
[0022] (2) The beam-rail integrated high-speed maglev track beam evacuation platform of this utility model can also serve as a temporary rescue site for rescue personnel, which provides convenience for rescue work; at the same time, the evacuation platform can also serve as an operating platform for inspection and maintenance personnel, making the daily maintenance of the track beam more convenient and reducing maintenance costs; at the same time, the pipelines laid under the platform plate or the pipelines installed on the railings can be used for cable laying, which also has the function of cable laying.
[0023] (3) This utility model is based on an evacuation platform of an integrated beam-track beam, which makes the structure of the track beam more compact and stable, reduces train delays and malfunctions caused by track problems, helps to improve the operating efficiency of maglev trains, and meets the needs of modern society for efficient and fast transportation. In addition, the structure of this utility model is simple, the principle is clear, and the construction is convenient, which reduces construction costs. Attached Figure Description

Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.
[0032] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited.

[0034] This utility model embodiment provides an integrated beam-track evacuation platform for high-speed maglev railways, located on the side of the track beam 6. Specifically, the evacuation platform includes a concrete beam evacuation platform 1 longitudinally arranged on the side of the track beam 6, with a platform slab 4 on the concrete beam evacuation platform 1; the platform slab 4 is connected to the ground via stairs 5. This utility model is applicable to situations where the distance between high-speed maglev railway stations is large, and passengers need a long time to walk to the nearest station after escaping to the evacuation platform. After passengers descend to the platform slab 4, they can evacuate to the ground via stairs 5. For single-track lines, the concrete evacuation platform 1 is erected on one side of the single-track high-speed maglev track beam; for double-track lines, the concrete evacuation platform 1 is erected between the double-track high-speed maglev track beams.
[0035] Preferably, a conduit for cable laying is buried beneath the platform plate 4. Preferably, for a single-line track, railings 3 are provided on both sides of the platform plate 4. When the railings 3 are installed, conduits can also be installed on the railings 3 for cable laying. Therefore, the beam-rail integrated high-speed maglev track beam evacuation platform of this utility model can simultaneously realize the functions of maintenance, cable channel laying, and emergency passenger evacuation.
[0036] Preferably, the evacuation platform is located outside the construction clearance of the high-speed maglev railway. As shown in the figure, in this embodiment, for a single-track line, the height of the concrete beam evacuation platform 1, platform slab 4, and railing 3 is lower than the construction clearance; for a double-track line, since the concrete beam evacuation platform 1 and platform slab 4 are located between the double-track high-speed maglev track beams, they can meet the requirement of being located outside the construction clearance of the high-speed maglev railway.
[0037] Preferably, due to the aerodynamic effects and dynamic responses generated during the operation of high-speed maglev trains, the height of the concrete beam evacuation platform 1 of this invention is lower than that of the track beam 6. Specifically, the concrete beam evacuation platform 1 is located below the outer side of a single-track high-speed maglev train or below the space between double-track high-speed maglev trains. More preferably, the middle section of the concrete beam evacuation platform 1 adopts a variable curvature design, meaning that the concrete beam evacuation platform 1 gradually thickens from the end to the middle at intervals along the longitudinal direction, with the greatest thickness at the location where the stairs 5 are set. The relatively low height of the concrete beam evacuation platform 1 of this invention, combined with the variable curvature design, reduces the impact of train aerodynamic effects on the evacuation platform and can evenly bear the load of evacuated crowds.
[0038] Preferably, due to the high-speed characteristics of high-speed maglev trains, the stopping and sliding position of the train cannot be controlled in an emergency. Therefore, compared with medium and low-speed maglev, the requirements for evacuation efficiency and safety are higher. The evacuation platform of this utility model is set along the entire length of the line, that is, the concrete beam evacuation platform 1 and the platform plate are set along the longitudinal length, which can meet the needs of high-speed maglev trains to quickly evacuate passengers in an emergency.
[0039] Preferably, since high-speed maglev trains have high speeds, they have higher requirements for the rigidity and stability of the track beams. Therefore, the evacuation platform of this utility model adopts a reinforced concrete structure with high rigidity and stability, which can meet the high-speed requirements of high-speed maglev trains.
[0040] This utility model embodiment also provides a high-speed maglev track beam with the aforementioned evacuation platform. In a single-track line, the high-speed maglev track beam includes several spaced-apart cantilever T-shaped piers 2, with a concrete beam evacuation platform 1 mounted on the cantilever T-shaped piers 2. The cantilever T-shaped piers 2 have cantilevers extending outward along one lateral side, and the concrete beam evacuation platform 1 is located at the top of the cantilever, with the platform plate 4 positioned laterally below and on the outer side of the high-speed maglev train. In a double-track line, the high-speed maglev track beam with the aforementioned evacuation platform includes several spaced-apart π-shaped piers, with the concrete beam evacuation platform 1 located at the top of the π-shaped piers and between the track beams of the two tracks; the platform plate 4 is located below the high-speed maglev trains between the two tracks.
[0041] Specifically, this utility model provides the following specific embodiments for single-line and double-line circuits:
[0042] Example 1
[0043] In this embodiment, as Figure 1 and Figure 2As shown, the single-track integrated high-speed maglev track beam includes a concrete beam evacuation platform 1, a cantilever T-shaped pier 2, a railing 3, a platform slab 4, and a staircase 5. The top of the cantilever T-shaped pier 2 supports the track beam 6, and the cantilever T-shaped pier 2 has a cantilever extending outward along one side in the lateral direction. The top of the cantilever is equipped with the concrete beam evacuation platform 1, which is longitudinally arranged on the side of the track beam 6. The platform slab 4 is provided on the concrete beam evacuation platform 1, which corresponds to the outer side and lower part of the high-speed maglev train in the lateral direction. The concrete beam evacuation platform 1, the railing 3, the platform slab 4, and the staircase 5 are all located outside the building clearance. The platform slab 4 is connected to the ground through the staircase 5. Passengers enter the platform slab 4 through the train door of the double-track maglev train and then evacuate to the ground through the staircase 5.
[0044] This embodiment sets up a concrete evacuation platform on one side of a single-track high-speed maglev track beam, which can meet the construction clearance of high-speed maglev railways and facilitate train evacuation. The single-track concrete beam evacuation platform integrates functions such as maintenance, cable channel and emergency evacuation channel for passengers.
[0045] Example 2
[0046] In this embodiment, as Figure 3 and Figure 4 As shown, the double-track high-speed maglev track beam, which is an integrated beam and track, includes a π-shaped pier, a concrete beam evacuation platform 1, a platform slab 4, and an escape staircase 5. The double-track track beams 6 are supported side-by-side on top of the π-shaped piers, and the evacuation platform is longitudinally positioned between the double-track track beams 6. Specifically, the concrete beam evacuation platform 1 is longitudinally positioned between the track beams 6, with its lateral sides connected to the inner sides of the double-track track beams 6, and its bottom not contacting the π-shaped piers. This allows the concrete beam evacuation platform 1 and the track beams 6 to form an integrated structure, improving rigidity and stability, and making it more suitable for the operating speed of high-speed maglev trains. The platform slab 4 is located longitudinally in the middle of the concrete beam evacuation platform 1. The platform slab 4 is located below the double-track high-speed maglev trains, and the concrete beam evacuation platform 1, platform slab 4, and escape staircase 5 are all located outside the building clearance. The platform slab 4 is connected to the ground via the staircase 5. Passengers enter the platform slab 4 through the train doors of the double-track maglev train and then evacuate to the ground via the staircase 5.
[0047] This embodiment uses a concrete evacuation platform erected between the double-track high-speed maglev beams to facilitate train evacuation in any direction. The double-track evacuation platform also integrates functions such as maintenance, cable access, and emergency passenger evacuation routes. Considering that the construction clearance of high-speed maglev lines is larger than that of medium- and low-speed maglev lines, the double-track evacuation platform in this embodiment preferably does not have a railing structure.
[0048] Those skilled in the art will readily understand that the above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
