Description

Technical Field

[0001] The utility model relates to the technical field of rail transportation, in particular to a track structure with reserved turnout insertion and laying conditions. Background Art

[0002] With the continuous deepening and improvement of the construction of urban rail transit or high-speed railway network in my country, a large number of new lines need to be introduced into existing stations or hubs. The functional demand for inserting turnouts in the ballastless track section of urban rail transit and high-speed railway construction and operation lines is becoming more and more urgent. The existing scheme requires the removal of the existing ballast bed structure and the re-casting of the turnout ballast bed. The construction time is tight, the workload is large, the site is limited, the process is many, and the cross-operation is frequent. At the same time, if the long-term turnouts are laid directly in the near future, because the line is only opened in one direction at this time, the other direction needs to be physically locked, which is a risk point in operation, and the maintenance workload of the turnouts is large, so it is not suitable to implement. Summary of the invention

[0003] The purpose of the utility model is to provide a track structure with reserved turnout laying conditions based on the above-mentioned deficiencies of the prior art, to reserve turnout laying conditions at stations with line access in the long term, and to achieve an organic connection between short-term lines and long-term turnouts.

[0004] The purpose of this utility model is achieved by the following technical solutions:

[0005] A track structure with reserved conditions for inserting turnouts, the track structure comprising rails, the rails being arranged on sleeper pads by fasteners, a plurality of sleeper pads being arranged below the rails along the line direction, the sleeper pads being supported on a ballast structure, and characterized in that bolt holes are reserved on the ballast structure at the future turnout arrangement position, anchor bolt holes matching the bolt holes are reserved on the sleeper pads, and iron seats for installing rails for the near-term line are arranged on the sleeper pads.

[0006] The short-term line is a short-term side line with a single turnout or a short-term straight line with a single turnout.

[0007] The short-term route is a short-term straight line with crossover lines.

[0008] The advantages of the utility model are: it can greatly reduce the engineering workload and implementation risks of turnout insertion, and only laying ordinary lines in the near future will not increase the maintenance workload and safety risk points; the structure is simple and reasonable, the construction is convenient, and it is suitable for promotion.

[0016] The following is a further detailed description of the features of the present invention and other related features through embodiments in conjunction with the accompanying drawings to facilitate understanding by technicians in the same industry:

[0017] like Figure 1-7 As shown, the marks 1-7 in the figure respectively represent: the near-term side rail 1, the sleeper pad 2, the near-term straight rail 3, the long-term turnout 4, the near-term crossover straight rail 5, the iron seat 6, and the anchor bolt hole 7.

[0018] Example: Figures 1 to 7 As shown, the track structure with reserved turnout insertion conditions in this embodiment is used to achieve an organic connection between the line to be opened in the near future and the line to be opened in the long term, including: Figures 1 to 3 The transformation between the short-term side or straight section and the long-term turnout of the single-turnout line shown in the figure, as well as Figure 4 and Figure 5 The crossover shown is a reconstruction between the near-term straight line and the future turnout of the crossover.

[0019] Specifically, the recent lines of single turnouts include Figure 1 The single turnout shown in the recent side line and Figure 2 The two cases of the recent straight strand line of the single turnout are shown. The recent side strand line of the single turnout includes a recent side strand rail 1, which is installed on a plurality of sleeper pads 2 arranged at intervals along the line direction. Similarly, the recent straight strand line of the single turnout includes a recent straight strand rail 3, which is also installed on a plurality of sleeper pads 2 arranged at intervals along the line direction.

[0020] Combination Figure 6 and Figure 7As shown, a special sleeper pad 2 is provided at the design position of the future turnout 4, and an iron seat 6 matching the near-term rail (the near-term side rail 1 or the near-term straight rail 2) is provided on the sleeper pad 2, and the near-term rail can be directly installed on the sleeper pad 2 through fasteners. The sleeper pad 2 matches the subrail bed structure, and anchor bolt holes 7 reserved for installing the future turnout 4 are provided at both ends of the plate body, and the subrail bed structure has been implemented in place according to the turnout bed. Therefore, the future turnout 4 can be fixedly installed on the sleeper pad 2 through the anchor bolt holes 7, thereby realizing the insertion of the future turnout 4. At this time, when inserting the future turnout 4, the existing near-term rails and fasteners are mainly removed.

[0021] like Figure 5 and Figure 6 As shown, when it comes to a crossing line, it includes a near-term crossing straight rail 5, which is also installed on the sleeper pad 2, and a special sleeper pad is installed at the design position of the future turnout 4, and the future turnout 4 is inserted and laid through the anchor bolt hole 7.

[0022] Although the above embodiments have described the concepts and embodiments of the purpose of the utility model in detail with reference to the accompanying drawings, ordinary technicians in this field can recognize that various improvements and modifications can still be made to the utility model without departing from the scope of the claims, so they are not described one by one here.
