Abstract
Description
Technical Field
[0001] The utility model relates to the field of protection devices, in particular to a rail transit U-shaped groove protection structure. Background Art
[0002] Currently, there are two types of U-shaped trough structures that connect elevated and underground rail transit sections: a closed concrete structure and a conventional U-shaped trough. The open U-shaped trough structure houses the subway's operating area, a core area of subway protection. To ensure safe subway operations, no other structures are allowed within the protected area. Therefore, a method to protect the open area of the subway U-shaped trough is urgently needed.
[0003] The defects and deficiencies of the existing technology: Conflicts with other municipal functions. If the subway is laid along the middle of the city road, this U-shaped trough structure will rigidly separate the plots on both sides of the road. In particular, pedestrians on both sides need to take a detour, which brings great inconvenience to residents. Sometimes during the construction of the subway and the initial operation of the subway, there is no demand for travel on both sides. However, with the opening of the subway, it will greatly drive the development of the surrounding area, and the demand for pedestrian travel will inevitably arise. Therefore, it is inevitable to build other pedestrian crossing facilities above the existing U-shaped trough. At present, in order to meet this demand, it is basically adopted to avoid the U-shaped trough section and use ground crossings on the front and back sides. For urban expressways, this method reduces the function of the expressway. Therefore, it is urgent to find a way to protect the open area of the subway U-shaped trough so that suitable crossing facilities can be built above the U-shaped trough. Utility Model Content

[0021] It is easy to understand that according to the technical solution of the present invention, without changing the essential spirit of the present invention, a person skilled in the art can propose a variety of interchangeable structural methods and implementation methods. Therefore, the following specific embodiments and drawings are only illustrative of the technical solution of the present invention and should not be regarded as the entire present invention or as a limitation or restriction of the technical solution of the present invention.
[0022] Example:
[0023] like Figure 1-4 As shown, prefabricated side walls 2 are fixedly connected to the tops of both sides of the U-shaped groove side wall structure 1. The specific installation method of the prefabricated side wall 2 is that a plurality of mounting sleeve mechanisms are evenly distributed at the bottom of the prefabricated side wall 2, and the mounting sleeve mechanisms are all pre-fixedly connected to the bottom of the prefabricated side wall 2.
[0024] The installation sleeve mechanism is an L-shaped steel sleeve 4 fixedly connected to both sides of the bottom of the prefabricated side wall 2 by fixing bolts or other fixing methods. A first circular hole 5 is opened on the horizontal plate of the L-shaped steel sleeve 4, and the side top of the U-shaped groove side wall structure 1 is fixedly connected with a steel bar 6 by post-embedded reinforcement technology. When the prefabricated side wall 2 is installed, the steel bar 6 passes through the first circular hole 5, and cement is poured in the L-shaped steel sleeve 4, which is used to fix the L-shaped steel sleeve 4 and the prefabricated side wall 2 on the side top of the U-shaped groove side wall structure 1.
[0025] A first notch 7 is provided on the top of the prefabricated side walls 2 on both sides, and a clamping column 11 is fixedly connected to both sides of the bottom of the prefabricated top plate 3 , and the two clamping columns 11 are slidably connected in the first notch 7 .
[0026] A second circular hole 15 is provided on the side of the prefabricated side wall 2, and the two second circular holes 15 are connected to the first slot 7. A third circular hole 19 is provided on the side of the clamping column 11. The second circular hole 15 and the third circular hole 19 are slidably connected to the second threaded rod 13. A baffle 14 is fixedly connected to one side of the second threaded rod 13. The outer wall of the second threaded rod 13 is threadedly connected to the first nut 12. The baffle 14 and the first nut 12 are placed on both sides of the prefabricated side wall 2 to ensure that the clamping column 11 is stably placed in the first slot 7.
[0027] A second slot 8 is provided on the side of the two prefabricated side walls 2 that are away from each other. The second slot 8 is connected to the first slot 7 and is placed at the bottom of the second circular hole 15. A box body 9 is fixedly connected to the prefabricated side wall 2. The box body 9 blocks the second slot 8, and one side opening of the box body 9 is connected to the second slot 8. A rotating column 18 is rotatably connected to the box body 9. The outer wall of the rotating column 18 is fixedly connected to a first threaded rod 10. One side of the first threaded rod 10 is placed at the bottom of the clamping column 11. Rotating the first threaded rod 10 causes the clamping column 11 to lift and remove the prefabricated top plate 3 from the prefabricated side wall 2.
[0028] A long opening 17 is opened on the box body 9, and the first threaded rod 10 passes through the long opening 17, and the first threaded rod 10 is threadedly connected with a second nut 16, which is pressed on the box body 9 to ensure that the first threaded rod 10 is stably installed on the box body 9.
[0029] The prefabricated top plate 3 is pressed on the top of the prefabricated side wall 2 so that the prefabricated top plate 3 is sealed relative to the prefabricated side wall 2, so that the prefabricated side wall 2 and the prefabricated top plate 3 form a closed space to prevent the track noise from polluting the environment.
[0030] In a specific implementation, multiple sets of steel bars 6 are first installed on the side panels of the U-shaped trough side wall structure 1, and the multiple sets of steel bars 6 are evenly distributed on the side panels of the U-shaped trough side wall structure 1. Then, the steel bars 6 prefabricated on the prefabricated side wall 2 are slidably connected to the first circular holes 5, and the L-shaped steel sleeve 4 is stably pressed against the U-shaped trough side wall structure 1. Then, cement is poured into the L-shaped steel sleeve 4, so that the prefabricated side wall 2 and the L-shaped steel sleeve 4 are stably installed on the U-shaped trough side wall structure 1.
[0031] When installing the prefabricated top plate 3, a crane is then used to hang the prefabricated top plate 3 on the top of the prefabricated side wall 2, so that the clamping column 11 is pressed into the first slot 7 on the top of the prefabricated side wall 2. At this time, the prefabricated top plate 3 can seal the top of the prefabricated side wall 2, so that the prefabricated top plate 3 and the prefabricated side wall 2 form a sealed space, which can reduce the noise pollution of the track.
[0032] At this time, the second threaded rod 13 is inserted into the second circular hole 15 and the third circular hole 19 , so that the clamping column 11 is stably placed on the prefabricated side wall 2 .
[0033] When the prefabricated top plate 3 needs to be disassembled, the second threaded rod 13 is removed, and the second nut 16 is loosened. Then, the first threaded rod 10 is hammered downward so that the first threaded rod 10 lifts the clamping column 11, thereby facilitating the removal of the prefabricated top plate 3.
[0034] The technical scope of the present invention is not limited to the contents described above. Those skilled in the art can make various deformations and modifications to the above embodiments without departing from the technical concept of the present invention, and these deformations and modifications should all fall within the scope of protection of the present invention.
