Description

Technical Field

[0001] This utility model relates to the field of railway subgrade construction, specifically to a roadbed structure for railway bridge engineering. Background Technology

[0002] The roadbed is the foundation of the railway track, an earthwork structure formed by excavation or filling. To facilitate drainage during rainy weather, some railway roadbeds have drainage structures on one or both sides. Existing drainage structures include roadbed slopes, intercepting ditches located at the top of the slopes, drainage ditches at the bottom of the slopes, and multiple guide ditches along the slopes. The intercepting and drainage ditches extend parallel to the length of the roadbed slope. Multiple guide ditches are spaced apart along the length of the slope and connect to both the intercepting and drainage ditches. The opening edges of the intercepting ditches are covered with filter screens, which cover the opening surfaces. These drainage structures reduce the accumulation of sand, soil, and debris in the intercepting ditches, thus minimizing their ability to intercept rainwater.

[0003] The existing drainage structure has the following problems: fallen leaves and other debris are filtered by the filter screen, causing the filter screen to become clogged, which in turn leads to insufficient drainage effect.

[0004] Based on the above situation, there is an urgent need for improved roadbed structures in railway bridge engineering to address the problem of insufficient drainage. Utility Model Content

[0005] The purpose of this invention is to address the problem of insufficient drainage in existing drainage structures, where fallen leaves and other debris are filtered out by the filter screen, causing the filter screen to become clogged and resulting in inadequate drainage.

[0006] The technical solution of this utility model is as follows:

[0007] Railway bridge engineering roadbed includes:

[0008] The roadbed body has slopes formed on its sides;

[0009] A merging system is installed on the slope, and the merging system includes several merging chambers distributed longitudinally and transversely and merging pipes communicating with the merging chambers;

[0010] A filter screen is detachably installed on the confluence chamber. The filter screen is provided with a movable rod and a fixed rod. An installation groove is formed in the confluence chamber to cooperate with the movable rod or the fixed rod.

[0011] In existing drainage structures, fallen leaves and other debris are filtered by the filter screen, causing it to become clogged and resulting in insufficient drainage. In this solution, when the upper filter screen is clogged by fallen leaves and other debris, some unfiltered debris will naturally flow into the lower filter screen with the water flow for further filtration. The filtered water will then enter the confluence pipe through the confluence chamber and be centrally drained, solving the problem of insufficient drainage. The movable rod can be retracted from the corresponding mounting slot, facilitating the removal and cleaning of the filter screen to restore the original drainage effect.

[0012] Furthermore, this solution is not limited to the operation method of the movable rod. One feasible solution is as follows: the movable rod is connected to an operating rod, the operating rod is connected to a cover, and a cylindrical body connected to the cover is formed on the filter screen. When this solution is adopted, the operating rod is moved by operating the cover to retract the movable rod from the corresponding mounting slot, so as to facilitate the removal of the filter screen. After the filter screen is installed, the cover contacts the cylindrical body to keep the operating rod dry.

[0013] Furthermore, in order to protect the operating lever, one feasible solution is that the cover is threadedly connected to the cylinder and a first sealing ring is provided between the cover and the cylinder. When this solution is adopted, when the cover is tightened, the first sealing ring can prevent water from entering the cylinder.

[0014] Furthermore, to further protect the operating rod, one feasible solution is to install a second sealing ring inside the cylinder and have the operating rod pass through the second sealing ring. When this solution is adopted, a sealed space can be formed between the first sealing ring and the second sealing ring, which can further protect the operating rod.

[0015] Furthermore, to prevent water from contacting the cover and cylinder, one feasible solution is to rotatably connect a cover plate to the filter screen and connect the cover plate to a guide plate. The cover plate is positioned above the cylinder. With this solution, the cover plate and the guide plate can keep the cover and cylinder dry.

[0016] Furthermore, this solution does not exclusively limit the specific structure of the merging pipeline. One feasible solution is that the merging pipeline includes branch pipelines connected to the merging chamber and a main pipeline connected to the branch pipelines. The lower end of the main pipeline is connected to a drainage ditch. When this solution is adopted, the water can flow into the drainage ditch in sequence through the branch pipelines and the main pipeline, so as to facilitate timely drainage.

[0017] Compared with existing technologies, the beneficial effects of this utility model are:

[0018] 1. When the upper filter screen is blocked by fallen leaves and other debris, some unfiltered debris will flow naturally into the lower filter screen for further filtration. The filtered water will enter the confluence pipe through the confluence chamber and be discharged in a concentrated manner, thus solving the problem of insufficient drainage effect. The movable rod can be retracted from the corresponding mounting slot to facilitate the disassembly and cleaning of the filter screen, so as to restore the original drainage effect.

[0019] 2. Since the movable rod is connected to an operating rod, and the operating rod is connected to a cover, and a cylindrical body connected to the cover is formed on the filter screen, the operating rod is moved by operating the cover to retract the movable rod from the corresponding mounting slot, so as to facilitate the removal of the filter screen; after the filter screen is installed, the cover contacts the cylindrical body to keep the operating rod dry;

[0020] Third, since the filter screen is rotatably connected to a cover plate and the cover plate is connected to a guide plate, and the cover plate is located above the cylinder, the cover plate and the guide plate can keep the cover and the cylinder dry. Attached Figure Description

[0034] It should be noted that relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus. Unless otherwise specified, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes the element.

[0035] The features and performance of this utility model will be further described in detail below with reference to the embodiments.

[0036] Example:

[0037] Please refer to Figure 1 , Figure 2 and Figure 3 A roadbed for railway bridge engineering, comprising:

[0038] The road base 1 has a slope 11 formed on its side;

[0039] The merging system 2 is installed on the slope 11. The merging system 2 includes several merging chambers 21 distributed longitudinally and laterally and merging pipes 22 connected to the merging chambers 21.

[0040] The filter screen 3 is detachably installed on the confluence chamber 21. The filter screen 3 is provided with a movable rod 31 and a fixed rod 32. The confluence chamber 21 has an installation groove 23 that cooperates with the movable rod 31 or the fixed rod 32.

[0041] In existing drainage structures, fallen leaves and other debris are filtered by the filter screen, causing it to become clogged and resulting in insufficient drainage. In this solution, when the upper filter screen 3 is clogged by fallen leaves and other debris, some unfiltered debris will flow naturally into the lower filter screen 3 for further filtration. The filtered water will then enter the confluence pipe 22 through the confluence chamber 21 and be centrally drained, solving the problem of insufficient drainage. The movable rod 31 is retracted from the corresponding mounting slot 23, making it easy to disassemble the filter screen 3 and clean it to restore the original drainage effect.

[0042] Reference Figure 5This solution is not limited to the operation mode of the movable rod 31. One feasible solution is as follows: the movable rod 31 is connected to the operating rod 311, the operating rod 311 is connected to the cover 312, and the filter screen 3 has a cylinder 33 connected to the cover 312. When this solution is adopted, the operating rod 311 is moved by operating the cover 312 to make the movable rod 31 retract from the corresponding mounting groove 23, so as to facilitate the removal of the filter screen 3. After the filter screen 3 is installed, the cover 312 contacts the cylinder 33 to keep the operating rod 311 dry.

[0043] To protect the operating lever 311, one feasible solution is to thread the cover 312 to the cylinder 33 and provide a first sealing ring 313 between the cover 312 and the cylinder 33. When this solution is adopted, after the cover 312 is tightened, the first sealing ring 313 can prevent water from entering the cylinder 33.

[0044] To further protect the operating rod 311, one feasible solution is to install a second sealing ring 331 inside the cylinder 33 and pass the operating rod 311 through the second sealing ring 331. When this solution is adopted, a sealed space can be formed between the first sealing ring 313 and the second sealing ring 331, which can further protect the operating rod 311.

[0045] Reference Figure 4 and Figure 5 To prevent water from contacting the cover 312 and the cylinder 33, one feasible solution is to rotatably connect a cover plate 34 to the filter screen 3 and connect a guide plate 35 to the cover plate 34. The cover plate 34 is positioned above the cylinder 33. With this solution, the cover 312 and the cylinder 33 can be kept dry under the action of the cover plate 34 and the guide plate 35.

[0046] Reference Figure 2 This scheme does not limit the specific structure of the combined pipe 22. One feasible scheme is that the combined pipe 22 includes a branch pipe 221 connected to the combined chamber 21 and a main pipe 222 connected to the branch pipe 221. The lower end of the main pipe 222 is connected to a drainage ditch 223. When this scheme is adopted, the water can flow into the drainage ditch 223 in sequence through the branch pipe 221 and the main pipe 222, so as to facilitate timely drainage.

[0047] To address the issue of insufficient drainage, this design incorporates a system where, when the upper filter screen 3 is clogged with fallen leaves or other debris, some unfiltered debris flows naturally into the lower filter screen 3 for further filtration. The filtered water then enters the confluence pipe 22 through the confluence chamber 21 and is centrally drained, thus resolving the problem of insufficient drainage. This allows the movable rod 31 to retract from its corresponding mounting slot 23, facilitating the removal and cleaning of the filter screen 3 to restore the original drainage performance.

[0048] To keep the operating rod 311 dry, in this design, the movable rod 31 is connected to the operating rod 311, and the operating rod 311 is connected to the cover 312. A cylindrical body 33 connected to the cover 312 is formed on the filter screen 3. By operating the cover 312, the operating rod 311 is moved so that the movable rod 31 retracts from the corresponding mounting groove 23, so as to facilitate the removal of the filter screen 3. After the filter screen 3 is installed, the cover 312 contacts the cylindrical body 33 to keep the operating rod 311 dry.

[0049] In order to keep the cover 312 and the cylinder 33 dry, in this solution, since the filter screen 3 is rotatably connected to the cover plate 34 and the cover plate 34 is connected to the guide plate 35, and the cover plate 34 is set above the cylinder 33, the cover 312 and the cylinder 33 can be kept dry under the action of the cover plate 34 and the guide plate 35.
