Description

Technical Field

[0001] The invention belongs to the field of rail transportation, and in particular relates to a stacked passing station for an intercity railway or an urban (suburban) railway. Background Art

[0002] In recent years, urban agglomerations such as the Beijing-Tianjin-Hebei, Yangtze River Delta, Pearl River Delta, and Greater Bay Area have gradually developed and matured. Intercity railways, as high-capacity rapid public transportation systems connecting various node cities, have assumed the role of backbone lines in the public transportation network of urban agglomerations, and their demand continues to increase.

[0003] According to the research results of public transportation service evaluation, travel time is a bottleneck factor restricting the development of public transportation. Intercity railways and urban (suburban) railways generally have longer lines. Based on factors such as the number of stations, the distance between stations, and the operating time, multiple passing stations are set up at appropriate locations on the line. The "major station express" operation mode can effectively reduce train travel time, enable intercity railways to better meet passenger demand, and provide strong support for the healthy and sustainable development of urban agglomerations.

[0004] A common passing station consists of a platform, a stop line and a passing track. The passing track is usually used to pass through the station in a straight line, and a switch is set near the platform. A stop station is set after the passing track is led out to the edge of the platform. The passing track, stop line and platform are arranged in a plane on the same station floor. Figures 1 to 4 Several commonly used layout types of level crossing stations are shown. In the existing commonly used crossing stations: a platform is set up in the station, using an island platform or a side platform; the up line 3 and the up stop line 5 are connected by a single crossover 7 and arranged on one side of the same level of the platform 1; the down line 4 and the down stop line 6 are connected by a single crossover 8 and arranged on the other side of the same level of the platform 1; in addition, safety lines 9 and 10 are set in the exit direction of the up stop line 5 and the down stop line 6.

[0005] The commonly used passing stations at present have the following main defects: no matter whether an island platform or a side platform is adopted, since the up line 2, the up stop line 4, the down line 3 and the down stop line 5 are all arranged in parallel on the same floor, the main structure of the station is wide and the project scale is large, there are great difficulties in traffic diversion, pipeline relocation, house demolition, construction site, etc. Summary of the invention

[0006] The above defects and shortcomings of the existing intercity railway passing stations are solved by the present invention, and a stacked passing station for intercity railway and urban (suburban) railway is proposed. The present invention arranges the up line, the up stop line and the up platform on the same level at the upper platform level, and the down line, the down stop line and the down platform on the same level at the lower platform level. The width of the main structure of the station is reduced, saving engineering investment.

[0007] In order to achieve the above-mentioned purpose, the present invention is implemented through the following technical scheme: a stacked passing station of an intercity railway, an urban (suburban) railway, comprising a stacked upper platform layer, a bottom platform layer and a station hall layer, wherein an upward platform is arranged in the upper platform layer; a downward platform is arranged in the bottom platform layer, and the upward platform and the downward platform are arranged parallel and overlapping up and down within the station range.

[0008] Furthermore, the up platform and the down platform are both side platforms.

[0009] Furthermore, the upward platform is provided with an upward line and an upward stop line of equal height, and both are arranged on the same side of the upward platform, and both ends of the upward stop line are connected to the upward line through an upward single crossover line;

[0010] The down platform is provided with a down line and a down stop line of equal height, and both are arranged on the same side of the down platform, and both ends of the down stop line are connected to the down line through a down single crossover line;

[0011] The up line and the down line are arranged parallel and overlapping in the station;

[0012] The upward stop line and the downward stop line are arranged in parallel and overlapped with each other in the station range.

[0013] Furthermore, the upward single crossover and the downward single crossover are arranged in parallel and overlapped with each other.

[0014] Furthermore, the upward single crossover and the downward single crossover are respectively connected to the upward and downward lines on the same level through configured turnouts, and the turnouts are single-opening turnouts.

[0015] Furthermore, the upward single crossover and the downward single crossover are respectively provided with safety lines.

[0016] Compared with the prior art, the invention has the following beneficial effects.

[0017] 1. In the intercity railway stacked passing station of the present invention, the up line and the down line, the up stop line and the down stop line, the up platform and the down platform are respectively arranged in an up-and-down overlapping manner. Compared with the existing passing station scheme in which the up line, the up stop line, the down line, the down stop line and the platform are arranged on the same level, the width of the main structure of the station is reduced by about 1 / 2, saving engineering investment; at the same time, it avoids the problems of limited surrounding construction land, difficult traffic organization and relief, and large amount of building demolition.

[0018] 2. In the intercity railway stacked passing station of the present invention, the up platform and the down platform are overlapped up and down to form a stacked side station, which replaces the horizontal area with the vertical space. The overall scale of the station is small and the area occupied is small. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0023] The following will describe the implementation methods of the present invention in detail with reference to the accompanying drawings and examples, so as to fully understand and implement the implementation process of how the present invention applies technical means to solve technical problems and achieve technical effects.

[0024] like Figure 5 As shown, a stacked passing station for intercity railway, urban area (suburban) railway, includes a stacked lower platform layer, an upper platform layer and a station hall layer. Among them: the station hall layer is located on the first underground floor, the upper platform layer is located on the second underground floor, and the lower platform layer is located on the third underground floor. The height difference between the up platform 1 and the down platform 2 is generally set to 7 to 8 meters to meet the platform function and the structural strength of the overlapping setting of the track area.

[0025] The upper platform layer includes an up platform 1, an up line 3, an up stop line 5 and an up single crossover line 7. The lower platform layer includes a down platform 2, a down line 4, a down stop line 6 and a down single crossover line 8.

[0026] Both the up platform 1 and the down platform 2 are side platforms, located at the upper platform level and the lower platform level respectively, and the two are arranged parallel and overlapping at the top and bottom.

[0027] The up line 3 and the up stop line 5 are arranged on one side of the up platform 1, and the up line 3 is connected to the up stop line 5 through the up single crossover 7, in the exit direction of the up stop line 5. The down line 4 and the down stop line 6 are arranged on one side of the down platform 2, and the down line 4 is connected to the down stop line 6 through the down single crossover 8; in the exit direction of the down stop line 6.

[0028] The up line 3 and the down line 4 are arranged in parallel and overlapped up and down within the station range. The up stop line 5 and the down stop line 6 are arranged in parallel and overlapped up and down within the station range.

[0029] In the intercity railway stacked passing station of the present invention, in the section at the small mileage end of the station, the up line 3 and the down line 4 are transitioned from the plane layout to the inside of the stacked station, the up line 3 enters the upper platform layer, and the down line 4 enters the lower platform layer; within the station range, the up stop line 5 and the down stop line 6 are connected to the up line 3 and the down line 4 respectively through the up single crossover line 7 and the down single crossover line 8; the up stop line 5 and the down stop line 6 are arranged in parallel and overlapped up and down, and are respectively located at the edges of the up platform 1 and the down platform 2. Outside the station range at the large mileage end, the up line 3 and the down line 4 are gradually transitioned from the stacked layout in the station to the plane layout of the section.

[0030] Compared with the existing passing station scheme in which the up platform 1, down platform 2, up line 3, down line 4, up stop line 5 and down stop line 6 are arranged in parallel on the same floor, the passing station in this embodiment can significantly reduce the main width and project scale of the intercity railway passing station, reduce land occupation and demolition, and save project costs.

[0031] In order to further improve the operational safety performance, in the intercity railway stacked passing station of the present invention, corresponding upward safety lines 9 and downward safety lines 10 are respectively set in the exit direction of the upward stop line 5 and the downward stop line 6 to provide operational safety guarantee for the exit of the parked vehicles. The upward stop line 5 and the downward stop line 6 are respectively equipped with four sets of turnouts connected to the upward line 3 and the downward line 4 on the same level. The turnout is a single-opening turnout, and generally a No. 9 turnout can be used.
