Description

Technical Field

[0001] This application relates to the technical field of railway cable track duct configuration, and in particular to a method for configuring railway cable track ducts. Background Technology

[0002] Railway cable conduits are cable protection pipes used under railway lines or at crossings. They are mainly used to protect railway signaling, power, and communication cables, ensuring that the cables are not physically damaged or affected by external environmental factors when passing over tracks or track crossings. These conduits are typically installed under the railway ballast, between tracks, or around other railway facilities to accommodate various types of cables, ensuring that the cables are not worn, broken, or exposed to moisture during long-term use.

[0003] During the installation of railway cable ducts, the precise selection and quantity of ducts have a significant impact on construction progress, cost control, and subsequent maintenance. Traditional methods often rely on experience or rough estimates, which can easily lead to material waste, construction delays, and unnecessary labor costs. Summary of the Invention

[0004] To address the problem of material waste caused by traditional railway cable track duct configuration methods, this application provides a railway cable track duct configuration method.

[0005] The technical solution provided in this application for configuring railway cable crossing pipes is as follows: A method for configuring railway cables through rail conduits includes the following steps: S1. Draw cross-sectional views of different types of rail pipes and cross-sectional views of various types of cables in CAD. S2. Based on the CAD drawings, create cross-sectional models of the rail pipes and cables and indicate their models; S3. Simulate the cable crossing using physical models and CAD cross-sectional diagrams; S4. Determine the quantity and size of the track tubes based on the experimental data, and prepare a material plan for the track tubes.

[0006] By adopting the above technical solution, when the reported quantity of cable crossing pipes exceeds the actual use, or the reported size of the cable crossing pipes is too large, it will increase the cost of purchasing materials. When the reported quantity and size are smaller than the actual use, materials will need to be purchased again, which will lead to delays in on-site construction, extend the construction period, waste manpower, and increase construction costs. By simulating cable crossings through physical models and CAD cross-sectional diagrams, the required size and quantity of cable crossing pipes at the crossing locations can be intuitively displayed, providing accurate usage quantities and specifications for on-site use, saving construction costs, reducing the construction period, and improving work efficiency.

[0007] Preferably, a CAD model of the cable cross-section is made according to the outer diameter of the signal cable of different specifications and models, and the cable model and number of cores are marked on each model.

[0008] By adopting the above technical solution, and by creating a CAD model of the cable cross-section and indicating the cable type and number of cores, the space required for each type of cable can be accurately calculated. This helps to avoid insufficient or excessive space waste during cable installation, provides a scientific basis for construction, and ensures that the cable can pass smoothly and safely through the cable conduit.

[0009] Preferably, steel pipe cross-section models of Φ50, Φ80, Φ100, Φ150, and Φ200 are produced.

[0010] By adopting the above technical solution and making cross-sectional models of steel pipes of different specifications, a clearer reference can be provided for the selection of each rail-crossing pipe model. Based on the different specifications of rail-crossing pipes, the layout of rail-crossing pipes can be optimized, avoiding the misuse of inappropriate sizes, while reducing material procurement and construction costs.

[0011] Preferably, during the simulation experiment, the amount of free space between the cable models is used to simulate the cable bending amount, and the area occupied by the simulated cable on the rail pipe is calculated.

[0012] By adopting the above technical solution, the cable will inevitably have a certain amount of bending in the rail conduit. Through simulation experiments, the space required after the cable bends can be accurately calculated, and the design of the rail conduit can be optimized. This can avoid the problem of cable damage or incompatibility caused by unreasonable dimensions of the rail conduit, and ensure the smooth passage of the cable in the rail conduit.

[0013] Preferably, the physical model uses magnetic stickers and iron sheets as materials.

[0014] By adopting the above technical solution and using magnetic stickers and iron sheets as simulation model materials, not only can the size of the model be ensured to be accurate, but it also has good adsorption properties, making it easy to make and adjust. The magnetic stickers and iron sheets are non-polluting and non-corrosive, and will not have an impact on the environment during the simulation process, which is conducive to environmental protection and safe construction.

[0015] Preferably, the selection of the track-passing pipe must meet the requirements of the "Railway Signal Engineering Construction Quality Acceptance Standard" TB10419-20185.3.5.10. When the optical cable is laid in the pipe, the inner diameter of the pipe shall not be less than 1.5 times the outer diameter of the optical cable.

[0016] By adopting the above technical solution, and ensuring that the selection of the rail-crossing pipe meets the requirements of the "Railway Signaling Engineering Construction Quality Acceptance Standard," situations where the pipe size does not meet the regulations are avoided. This ensures that the optical cable can pass smoothly through the rail-crossing pipe and prevents the normal transmission of the cable from being affected by the pipe being too small. This helps to guarantee construction quality and reduce later maintenance costs.

[0017] Preferably, when making physical models, protective equipment against electric shock should be worn.

[0018] By adopting the above technical solutions and wearing necessary protective equipment such as goggles, insulated gloves, and insulated boots when making models, workers can be effectively protected from electrical hazards, physical injuries, and other potential safety risks. This improves on-site work safety and ensures the health and safety of construction personnel.

[0019] Preferably, after collecting the processing scraps from the physical model making process, they should be disposed of according to the required waste sorting.

[0020] By adopting the above-mentioned technical solutions, the scraps generated during the processing are collected and sorted for disposal, which meets environmental protection requirements and helps reduce the impact of construction waste on the environment. Through reasonable waste management, not only can the reuse rate of resources be improved, but the construction process can also be ensured to comply with environmental regulations and requirements, thus promoting sustainable construction.

[0021] In summary, this application includes at least one of the following beneficial technical effects: When the number of cable crossing pipes reported exceeds the actual usage, or the reported size of the cable crossing pipes is too large, it will increase the cost of purchasing materials. When the reported quantity and size are less than the actual usage, materials will need to be purchased again, which will delay the on-site construction progress, extend the construction period, waste manpower, and increase construction costs. By simulating cable crossings through physical models and CAD cross-sectional diagrams, the required size and quantity of cable crossing pipes at the crossing locations can be intuitively displayed, providing accurate usage quantities and specifications for on-site use, saving construction costs, reducing the construction period, and improving work efficiency. By creating a CAD model of the cable cross-section and indicating the cable type and number of cores, the space required for each type of cable can be accurately calculated. This helps to avoid insufficient or excessive space waste during cable installation, provides a scientific basis for construction, and ensures that the cable can pass smoothly and safely through the cable conduit. Cables inevitably bend to a certain extent when passing through a conduit. Through simulation experiments, the space required after the cable bends can be accurately calculated, and the design of the conduit can be optimized. This can avoid cable damage or incompatibility caused by unreasonable conduit dimensions, and ensure the smooth passage of cables through the conduit. Attached Figure Description

[0022] Figure 1This is a flowchart of the railway cable track pipe configuration method according to an embodiment of this application. Detailed Implementation

[0023] The following is in conjunction with the appendix Figure 1 This application will be described in further detail.

[0024] This application discloses a method for configuring railway cable track-crossing conduits. (Refer to...) Figure 1 The construction method for configuring railway cable crossing pipes includes the following steps: S1. Draw cross-sectional views of different types of rail pipes and cables in CAD to provide accurate basic data for subsequent model making and ensure the matching between the dimensions of the rail pipes and cables.

[0025] S2. Based on the CAD drawings, create cross-sectional models of the rail pipes and cables and indicate their models; Based on the outer diameter of signal cables of different specifications and models, CAD models of cable cross sections are made, and the cable model and number of cores are marked on each model. Steel pipe cross section models of Φ50, Φ80, Φ100, Φ150, Φ200, etc. are also made. The models can intuitively show the laying of different types of cables in the rail conduit, ensuring that the cables can pass smoothly during the installation process.

[0026] The cable physical model uses magnetic stickers, and the rail pipe physical model uses iron sheets. Magnetic stickers and iron sheets have good adsorption properties, making them easy to make and adjust. Magnetic stickers and iron sheets are non-polluting and non-corrosive, and will not affect the environment during the simulation process, which is conducive to environmental protection and safe construction. When making the physical model, it is necessary to wear safety goggles, insulating gloves, insulating boots and other protective equipment against electric shock. S3. Using the prepared physical model and CAD cross-sectional view, simulate the process of the cable passing through the passageway, simulate the cable bending amount by the allowance between the cable models, and calculate the area occupied by the simulated cable in the passageway. Through the simulation experiment, calculate the bending amount and space occupation of the cable in the passageway, and further optimize the size and number of passageways based on the experimental data. Taking a 100mm inner diameter guide tube as an example, place 5 PTYL23 42-core cables inside the guide tube and lay the 5 cables in the steel pipe. This will result in the need to place one 100mm inner diameter guide tube at this passageway location.

[0027] Based on actual conditions, cables will bend when passing through the rail conduit. In the simulation experiment, it is necessary to leave a gap between the cable models to simulate the cable bending amount, and the area occupied by the simulated material through the rail conduit was calculated. Taking PTYL23 42 core as an example: PTYL23 42-core cable cross-sectional area S 电缆 =Π*15.852 =786.35mm 2 The cross-sectional area S of the Φ200 rail tube 50 =Π*100 2 =31400mm 2 The cross-sectional area S of the Φ150 rail guide tube 150 =Π*75 2 =17662.5mm 2 The cross-sectional area S of the Φ100 rail pipe 100 =Π*50 2 =7850mm 2 The cross-sectional area S of the Φ80 rail pipe 80 =Π*40 2 =5024mm 2 A Φ200 conduit can accommodate 17 42L core cables, occupying the following area: S 占用 = (786.35mm) 2 *17 / 31400mm 2 ) * 100% = 42.5% A Φ150 conduit can accommodate 11 42L core cables, occupying the following area: S 占用 = (786.35mm) 2 *11 / 17662.5mm 2 ) * 100% = 48.9% A Φ100 conduit can accommodate 5 42L cables, occupying the following area: S 占用 = (786.35mm) 2 *5 / 7850mm 2 ) * 100% = 50% An 80mm diameter conduit can accommodate three 42L core cables, occupying the following area: S 占用 = (786.35mm) 2 *3 / 5024mm 2 ) * 100% = 46.9% Therefore, it can be concluded that when the cable passes through the cable passage, the cross-sectional area of ​​the cable occupies about 45% of the cross-sectional area of ​​the cable track, and about two-fifths of the area needs to be reserved for the placement test.

[0028] S4. Based on the experimental data, determine the quantity and size of the track-passing pipes, and prepare a track-passing pipe material plan. The selection of track-passing pipes must meet the requirements of the "Railway Signal Engineering Construction Quality Acceptance Standard" TB10419-2018 5.3.5.10. When optical cables are laid in the pipes, the inner diameter of the pipes shall not be less than 1.5 times the outer diameter of the optical cables. Ensure that the size and quantity of track-passing pipes are accurately selected to avoid over- or under-purchasing, thereby reducing material procurement costs and the risk of construction delays.

[0029] The implementation principle of the railway cable crossing pipe configuration method in this application embodiment is as follows: When the number of crossing pipes reported exceeds the actual use, or the size of the crossing pipes reported is too large, it will increase the cost of purchasing materials. When the reported quantity and size are smaller than the actual use, materials will need to be purchased again, which will lead to delays in on-site construction, extend the construction period, waste manpower, and increase construction costs. By simulating the cable crossing through the tunnel using physical models and CAD cross-sectional diagrams, the required size and quantity of crossing pipes at the crossing position can be intuitively displayed, providing accurate usage quantity and specifications for on-site use, saving construction costs, reducing the construction period, and improving work efficiency.

[0030] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
