Description

Technical Field

[0001] The utility model relates to the technical field of rail transportation, in particular to a mound type vehicle stop structure. Background Art

[0002] With the development of rail transit, the number of rail transit lines has increased. When the end of a rail transit line is a road cut or a municipal road, it is necessary to add a vehicle stop structure to ensure that rail transit vehicles will not run out of the track.

[0003] At present, common car stop structures have an elastic energy-absorbing element, such as a hydraulic component or a spring. When a rail transit vehicle hits the car stop structure at high speed, the energy-absorbing element absorbs the impact force to achieve the effect of stopping; however, such a structure is often complex and difficult to maintain. In addition, car stop structures are also commonly steel structures. Such steel structure car stops are mostly prefabricated structures, which have the advantage of being more convenient to construct. However, after several years of use, there is a risk of reduced structural safety, and there is a need to dismantle and reinstall. Summary of the invention

[0004] The purpose of the utility model is to provide a mound type vehicle stop structure according to the above-mentioned deficiencies of the prior art, which can stop vehicles on rail transit lines through a combination of a concrete portal frame and rammed earth.

[0005] The purpose of this utility model is achieved by the following technical solutions:

[0006] A mound-type vehicle stop structure is arranged at the end position of a rail transit line, and the rail transit line includes steel rails. The characteristic is that the vehicle stop structure includes a concrete portal frame, and rammed earth is arranged inside the concrete portal frame. The concrete portal frame encloses the rammed earth, and the length of the concrete portal frame is sufficient to allow the steel rails to extend into the concrete portal frame by a certain distance and be partially covered by the rammed earth.

[0007] The concrete portal frame comprises a retaining wall and a side wall, wherein the retaining wall is arranged at the end position of the rail transit line, the side walls are arranged on both sides of the retaining wall, and the front side of the side wall has a front support section extending into the foundation.

[0008] The bottom of the retaining wall is buried below the foundation, and the end of the retaining wall is provided with an enlarged foundation.

[0009] The front support section is arranged in a 1:1 slope form, and its bottom end partially extends into the foundation.

[0010] The concrete portal frame is a C40 concrete frame.

[0011] The utility model has the advantages of strong stopping ability, safety and reliability, convenient construction, low engineering cost, simple and reasonable structure and suitability for promotion. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Figure 1 It is a schematic diagram of the structure of the utility model;

[0015] 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:

[0016] like Figure 1-3 As shown, the marks 1-9 in the figure respectively represent: rail 1, sleeper 2, concrete portal frame 3, rammed fill 4, side wall 5, retaining wall 6, front support section 7, foundation 8, and expanded foundation 9.

[0017] Example: Figures 1 to 3 As shown, the mound type vehicle stop structure in this embodiment is arranged at the end position of the rail transit line, for example, including the end position of the test line starting point and the end point of the track bed. The structure of the rail transit line includes a rail 1 and a sleeper 2, wherein the rail 1 is carried on the top of the sleeper 2 for the rail transit vehicle to travel, and the sleeper 2 is arranged on the track bed.

[0018] Combination Figures 1 to 3 As shown, the earth mound type vehicle stop structure in this embodiment includes two parts, a concrete portal frame 3 and rammed earth 4, wherein the rammed earth 4 is used as a mound carrier to resist the impact force of the rail transit vehicle, and the concrete portal frame 3 is arranged at the end position of the rail line to enclose the rammed earth 4, and the concrete portal frame 3 also plays a certain stopping role.

[0019] Specifically, in this embodiment, the concrete portal frame 3 adopts a C40 concrete frame, which includes a retaining wall 6 and a side wall 5, wherein the retaining wall 6 is arranged in the transverse direction of the line and is located at the end of the line, and the side wall is arranged in the longitudinal direction of the line and is arranged on both sides of the retaining wall 6 and extends from the outside of the line to the inside of the line.

[0020] like Figure 3As shown, an expanded foundation 9 is provided at the bottom of the retaining wall 6, and the expanded foundation 9 is buried below the foundation to provide the retaining wall 6 with a self-stabilizing effect and a certain strength, and to improve the stopping effect when a rail transit vehicle collides. A front support section 7 is provided on the front side of the side wall 6 in a 1:1 slope form, and the bottom of the front support section 7 is buried below the foundation to ensure the structural strength and stability at the position of the side wall 6. Through the design of the front support section 7 and the expanded foundation 9, the concrete portal frame 3 body can not only play a role in enclosing the rammed earth 4, but also provide a stopping effect.

[0021] The concrete portal frame 3 forms an enclosed area through the retaining wall 6 and the side wall 5, and rammed earth 4 is arranged in the enclosed area. The rammed earth 4 refers to the soil body compacted by tamping, which is compacted by tamping to improve the bearing capacity of the soil body, so that it can provide sufficient stopping effect when it is hit by a rail transit vehicle.

[0022] like Figure 3 As shown, the length of the concrete portal frame 3 is sufficient for the rail 1 to extend into the concrete portal frame 3 for a certain distance and to be partially covered with rammed earth 4 to improve the stopping effect.

[0023] 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.
