Abstract
Description
Technical Field
[0001] This utility model relates to the field of rail transit line design, specifically to a reorganization and layout structure for phased urban rail transit lines. Background Technology
[0002] As a key infrastructure for alleviating urban traffic congestion and improving public transportation efficiency, urban rail transit networks are becoming increasingly larger and more complex with urban development. During the planning, construction, and operation of urban rail transit networks, there are frequent needs to adjust, extend, split, or interconnect with other lines.
[0003] Line splitting and reorganization, as an important means of optimizing rail transit network, aims to separate a part of an existing line to form a new independent operating line. For example, an existing line can be split into two lines, realizing the splitting of a two-direction route into a four-direction route, or the sections of different lines can be reorganized and integrated to adapt to changes in passenger flow, optimize operation organization, or realize the access of new lines.
[0004] However, existing urban rail transit lines often face difficulties and challenges in restructuring and reorganizing their layouts, including significant interference with existing operational lines, long construction periods and low efficiency, complex line layouts, and high costs associated with restructuring and modification. Therefore, for lines that need to be dismantled in the future, it is necessary to reserve conditions for future line reorganization in advance during the line design phase. Utility Model Content
[0005] In view of one or more shortcomings of the existing technology, this utility model provides a phased reorganization layout structure for urban rail transit lines, which can reorganize lines in the future without affecting the operation of existing lines, improve the construction efficiency of dismantling and reorganizing lines in the future, reduce the size of stations, and reduce project investment.
[0006] To achieve the above objectives, this utility model adopts one or more of the following technical solutions:
[0007] A phased reorganization layout structure for urban rail transit lines includes a first line, a second line, and a third line. The first line is a line for near-term operation, while the second and third lines are lines for long-term operation. The first line, the second line, and the third line each include a left line and a right line arranged opposite to each other.
[0008] At the intersections of the first line and the second line, and the first line and the third line, a first reserved node and a second reserved node are respectively set. At the two reserved nodes, the left and right lines of the first line are respectively set as curved rails, which can be easily replaced with turnouts when dismantled in the future. The first line between the first reserved node and the second reserved node is a curved section.
[0009] At the first reserved node, a first long-term reserved structure extending along the design direction of the second line is arranged, and at the second reserved node, a second long-term reserved structure extending along the design direction of the third line is arranged, so as to reserve implementation conditions for the reorganization of the line in the future.
[0010] Wherein, the first long-term reserved structure includes at least an open-cut area, and / or, the second long-term reserved structure includes at least an open-cut area.
[0011] As a further implementation method, in the long-term construction, the curved rails of the left line at the two reserved nodes of the first line will be removed, and the curved rails of the right line will be replaced with turnouts. The first line will be connected to the second line and the third line through the turnouts respectively.
[0012] As a further implementation, the turnout at the first reserved node is arranged along the first long-term reserved structure to connect the first line and the second line, and the turnout at the second reserved node is arranged along the second long-term reserved structure to connect the first line and the third line.
[0013] As a further implementation, the right line of the first curved section becomes a connecting line between the second and third lines via turnouts at two reserved nodes.
[0014] As a further implementation, turnouts are respectively arranged at the first reserved node and the second reserved node.
[0015] As a further implementation, the curve radius of the right line of the first line is smaller than that of the left line; the right line of the first line does not have a transition curve, and the left line of the first line has a transition curve with a set distance at the first reserved node and / or the second reserved node.
[0016] As a further implementation, the first line has Station 1 and Station 2 distributed on both sides of the curve section, and Station 3 is set at the intersection of the second line and the third line.
[0017] As a further implementation, station one and station three are connected via the first line and the second line, and station two and station three are connected via the first line and the third line.
[0018] By adopting the above technical solution, the beneficial effects of this utility model are as follows:
[0019] 1. The line layout structure of this utility model is simple. The intersection points of the first line with the second and third lines, i.e. the two reserved nodes, are designed as curved rails in the near term, which can be easily decomposed and reassembled into turnouts during the long-term construction, thereby realizing the independent operation of each line.
[0020] 2. When carrying out long-term line reorganization, this utility model only needs to perform decomposition and reorganization work at the reserved nodes. It can be carried out without interrupting the operation of the existing line and without interfering with the operation of the first line.
[0021] 3. This utility model only requires cutting and replacing the curved rails of the left line of the first line at the reserved node with turnouts, which can significantly shorten the construction period and greatly improve construction efficiency.
[0022] 4. This utility model, by implementing the decomposition and reorganization of the line within the section, abandons the traditional method of decomposition and reorganization within the station, effectively reduces the construction scale of the stations at both ends, fundamentally and significantly reduces the project investment cost, and provides strong support for the economic efficiency and rationality of the project.

[0029] Example 1
[0030] In one typical embodiment of this application, a phased reorganization layout structure for urban rail transit lines is provided, such as... Figure 1-2 As shown, it includes a first line 1, a second line 2 and a third line 3. The first line 1 is the line to be operated in the near future, and the second line 2 and the third line 3 are the lines to be operated in the long term. The first line 1, the second line 2 and the third line 3 respectively include a left line and a right line that are set opposite to each other.
[0031] At the intersections of the first track and the second track, and the first track and the third track, a first reserved node 9 and a second reserved node 10 are respectively set. At the two reserved nodes, the left track 7 and the right track 8 of the first track are respectively set as curved rails, which can be easily replaced with turnouts when dismantled in the future. The first track between the first reserved node 9 and the second reserved node 10 is a curved section.
[0032] At the first reserved node, a first long-term reserved structure 11 extending along the design direction of the second line is arranged, and at the second reserved node, a second long-term reserved structure 12 extending along the design direction of the third line is arranged, so as to reserve implementation conditions for the reorganization of the long-term line.
[0033] The first long-term reserved structure 11 includes at least an open-cut area, and / or the second long-term reserved structure 12 includes at least an open-cut area.
[0034] Specifically, in combination Figure 1 and Figure 2 As shown, this embodiment of the phased route reorganization layout includes three routes: Route 1, Route 2, and Route 3. Route 1 is the route to be implemented in the near term, while Route 2 and Route 3 are routes to be implemented in the long term. Each of the three routes has two main lines: a left line and a right line. In the overall planning and design, Route 1 has two stations: Station 1 (4) and Station 2 (5); Route 2 and Route 3 each have one station: Station 3 (6).
[0035] Specifically, such as Figure 1As shown, Line 1 includes straight sections in the first and second directions, as well as a curved section between the two straight sections. Station 1 (4) is located on the straight section in the first direction, and Station 2 (5) is located on the straight section in the second direction. Station 3 (6) is located at the intersection of Line 2 (2) and Line 3 (3), and was constructed later.
[0036] Specifically, in combination Figure 1 As shown, the two ends of the first curve segment are the intersection points of the first line with the second line planned in the long term, and the intersection point of the first line with the third line planned in the long term, respectively. At these two intersection points, the first reserved node 9 and the second reserved node 10 are set as reserved line dismantling and reorganization points, and the conditions for future line reorganization are reserved at these points. When carrying out the future line reorganization, only the dismantling and reorganization work needs to be carried out at the two reserved nodes, without the need to dismantle other sections of the line. Therefore, the line reorganization can be carried out without interrupting the operation of the existing line, without interfering with the operation of the first line, which is conducive to ensuring the normal operation of the urban transportation network and minimizing the impact of line reorganization construction on transportation and logistics.
[0037] Preferably, at the two reserved nodes, the left and right tracks of the first line are respectively set as curved rails as a condition for future track reorganization, which facilitates the replacement with turnouts during future dismantling, thereby shortening the construction cycle and improving construction efficiency.
[0038] In this embodiment, during the recent line design, in combination with Figure 1 As shown, a first reserved node 9 and a second reserved node 10 are respectively set at the intersections of the first and second lines, and the first and third lines. A first long-term reserved structure 11 extending a certain distance along the design direction of the second line is arranged at the first reserved node, and a second long-term reserved structure 12 extending a certain distance along the design direction of the third line is arranged at the second reserved node, serving as reserved conditions for future line reorganization. Specifically, the first reserved node 9 and the first long-term reserved structure 11 are collectively referred to as the construction reserved area for the second line. This construction reserved area is located in the tunnel section, and its specific requirement is to reserve construction conditions for turnouts so as not to interfere with the operation of existing lines during future line reorganization and to improve construction efficiency. Similarly, the second reserved node 10 and the second long-term reserved structure 12 are collectively referred to as the construction reserved area for the third line. The third line construction reserved area is located in the tunnel section, and its specific requirement is also to reserve construction conditions for turnouts. It is easy to understand that the extension distance of the third line construction reserved area is not less than the length of the turnout.
[0039] In a further embodiment, combined with Figure 1As shown, during the recent implementation of the first line, the left line 7 and right line 8 of the first line at the two reserved nodes are set as curved rails. The civil engineering structures are reserved in advance in other locations in the reserved areas of the second and third lines, forming the first long-term reserved structure 11 and the second long-term reserved structure 12. The first long-term reserved structure 11 and the second long-term reserved structure 12 include at least the open-cut area to avoid the demolition of the civil engineering in the later stage.
[0040] Among them, such as Figure 1 As shown, at the first reserved node 9 and the second reserved node 10, the right line 8 of the first line has a curve radius of 350m and no transition curve is set; the left line 7 of the first line has a curve radius of 500m and the transition curve is set to be 20m long.
[0041] In this embodiment, after the completion of the long-term second and third lines and station three-stage implementation, combined with... Figure 2 As shown, the two reserved nodes on the first line can be decomposed and reassembled. Specifically, at the first reserved node 9, the curved rail on the left line of the first line is removed, and the curved rail on the right line is replaced with a turnout 13, allowing the right line 8 of the curved section of the first line to remain passable. Simultaneously, the turnout 13 is arranged along the first long-term reserved structure 11, connecting the straight section of the first line 1 in the first direction with the implemented second line 2, efficiently achieving line reassembly. Similarly, at the second reserved node 10, the curved rail on the left line is removed, and the turnout 13 is modified and arranged along the curved rail on the right line and the second long-term reserved structure, ensuring the right line of the curved section of the first line is passable. Simultaneously, the straight section of the first line 1 in the second direction is connected with the implemented third line 3, achieving line structure decomposition and reassembly. The specific type of turnout can be selected according to the different requirements of the project, such as turnout No. 6, turnout No. 9, and turnout No. 12. In this embodiment, turnout No. 12 is used.
[0042] In this embodiment, after the circuit structure is reorganized, as follows: Figure 2 As shown, the second line 2 and the third line 3 can operate independently. The right line 8 of the curved section of the first line serves as a connecting line between the second and third lines and is passable. Since the left line 7 of the curved section of the first line conflicts with the second and third lines, trains cannot pass through. Therefore, the left tunnel can be used as a civil defense or material storage area.
[0043] like Figure 2 As shown, after the line reorganization, Station 1 (4) and Station 3 (6) are connected via the existing Line 1 and the later-constructed Line 2, while Station 2 (5) and Station 3 (6) are connected via the existing Line 1 and the later-constructed Line 3.
[0044] The construction process of the phased reconfiguration of the line layout structure in this embodiment is as follows:
[0045] (1) Design the first line, the second line, the third line and the first station, the second station and the third station to stabilize the line and station positions.
[0046] (2) Reserved design at the intersection points of the first and second lines and the first and third lines, and reserve conditions for the implementation of turnouts in the future. In the near term, the left and right lines of the first line at the two reserved nodes will use curved rails. The curve radius of the right line is designed to be 350m and no transition curve is set. The curve radius of the left line is designed to be 500m and the transition curve is designed to be 20m.
[0047] (3) The first line is designed structurally, and the second line from station one to station three and the third line from station two to station three are designed and reserved for future construction, forming the first and second long-term reserved structures; among them, the third station, the first and second long-term reserved structures are designed and reserved using the open-cut method.
[0048] (4) First, the first line (from station one to station two) will be opened for operation. After the second line, the third line and station three are completed in the long term, the two reserved modification points of the first line will be decomposed and reorganized. The right curve connecting the first line and the second line, and the reserved area of the first line and the third line will be modified into turnouts. The left curve of the reserved area of the first line and the second line, and the reserved area of the first line and the third line will be removed.
[0049] (5) After the line structure is reorganized, the second line and the third line will operate independently. The right line of the first line will serve as a connecting line between the second and third lines. The left line will conflict with the second and third lines, and trains will not be able to pass. The left line tunnel will be used as a civil defense project or a material storage area.
[0050] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it. Those skilled in the art should understand that this utility model can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
