Description

Technical Field

[0001] This invention belongs to the field of tunnel drainage, specifically a tunnel drainage structure for high-altitude and cold regions. Background Technology

[0002] Tunnels are structures built underground or underwater to carry railway tracks for locomotives and rolling stock. Based on their location, they can be divided into three main categories: mountain tunnels, underwater tunnels, and urban tunnels.

[0003] Because the tunnel spans a long distance and is located in the soil, it is prone to water seepage and water accumulation. Therefore, a drainage structure is needed for the tunnel.

[0004] Typical tunnel drainage structures are too simple, relying solely on drainage pipes. When rain causes significant water seepage, this can easily lead to water accumulation in the tunnel. Furthermore, in cold regions, the low soil temperature can cause the slowly draining water to freeze, clogging the drainage system.

[0005] Therefore, the present invention provides a tunnel drainage structure for high-altitude and cold regions. Summary of the Invention

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0007] The technical solution adopted by this invention to solve its technical problem is as follows: A tunnel drainage structure for high-altitude and cold regions, comprising multiple receiving components, each receiving component including an accumulation tray. The inner side of the accumulation tray is hollow. Drainage pipes are fixedly connected to both sides of the accumulation tray. Adjacent receiving components are connected via drainage pipes. A connecting ring is fixedly installed on the outer side of the connection between two drainage pipes. Through holes are provided on both sides of the accumulation tray, and the drainage pipes communicate with the inner side of the accumulation tray through these through holes. A receiving base is fixedly installed on the top surface of the accumulation tray, and a receiving base is fixedly mounted on the top surface of the receiving base. Equipped with a drain pan, which is vertically positioned with the receiving base, the storage pan is buried in the soil of the tunnel during operation. The drain pan is placed in the center of the tunnel, and the receiving components are laid along the direction of the tunnel. Water in the tunnel will fall into the storage pan through the drain pan and the receiving base, and then be discharged outward through the drain pipe. The hollow space of the storage pan can act as a buffer. When a large amount of water rushes in from the outside, the storage pan can also store a large amount of water, and then slowly discharge it outward through the drain pipe. This can effectively deal with sudden large amounts of water accumulation and reduce the problem of water accumulating on the tunnel surface for a long time.

[0008] Preferably, a pull rope is provided in the middle of the inner side of the drainage pipe, and a cylinder is fixedly installed on the outer side of the pull rope. Several ice-breaking blocks are fixedly installed on the outer side of the cylinder. The ice-breaking blocks are cylindrical. A power component is provided at the end of the pull rope. The power component is used to pull the pull rope. During operation, the soil temperature in high-altitude and cold regions is low, which can easily cause the slowly drained water to freeze, clogging the drainage structure. With the ice-breaking blocks, the pull rope can be moved by the power component, which can move the cylinder. When the cylinder moves, the ice-breaking blocks can break up the frozen water around it, allowing the water to flow again, effectively reducing the problem of drainage failure caused by frozen water.

[0009] Preferably, a filter screen is fixedly installed in the middle of the inner side of the accumulation tray. The filter screen consists of three perforated plates, two of which are symmetrically arranged. The tops of the two perforated plates are fixed together by a third perforated plate, which is concave downwards. During operation, foreign particles are easily mixed into the accumulated water, which can easily cause blockage of the drain pipe. Furthermore, water rich in impurities is more likely to freeze. With the filter screen, the accumulated water falling from top to bottom can be filtered, and the particles in the water can be filtered onto the top perforated plate. At the same time, the naturally flowing water can also be blocked and filtered by the two perforated plates on the side, effectively reducing the number of particles in the water. This reduces the problem of blockage of the drain pipe caused by particle accumulation, and also makes the water flow cleaner. Reducing the number of particles in the water reduces the number of crystal nuclei that the water can adhere to when it freezes, thus slowing down the freezing speed.

[0010] Preferably, the power assembly includes a sliding plate, extension boxes are fixedly connected to both sides of the storage tray, the inner side of the extension boxes is hollow, the sliding plate is slidably connected to the inner side of the extension boxes, two transmission grooves are formed on the top surface of the sliding plate, two holes are formed on the top surface of the receiving base, a bending rod is slidably connected to the inner side of the holes, the bottom end of the bending rod passes through the transmission groove, one end of the pull rope is fixedly connected to the outer side of the sliding plate, a long plate is fixedly installed on the outer side of the bending rod near the top, a spring is fixedly installed on the long plate and the top surface of the receiving base, and the sliding plate is fixedly connected to the inner side of the receiving base. With spring two attached, the top ends of the two curved rods are fixedly connected to compression blocks. During operation, the compression blocks are placed on the tunnel surface. When a vehicle passes by, the compression blocks are pressed down, thereby continuously compressing the curved rods. The downward pressure of the curved rods causes the sliding plate to move to one side, which in turn pulls the pulling rope, thus moving the ice-breaking block. After the vehicle passes, the sliding plate returns to its original position due to the rebound of spring one and the push-out of spring two. This design achieves the effect of moving the cylinder and the ice-breaking block without consuming other energy. At the same time, the overall structure is mechanically driven, which reduces the failure rate compared to using electronic equipment.

[0011] Preferably, the ice-breaking blocks are divided into three groups, which are equidistantly distributed on the outside of the cylinder. The first group consists of five ice-breaking blocks arranged in a equidistant ring, with the ends of the ice-breaking blocks fitting against the inner wall of the drain pipe. The second group consists of three ice-breaking blocks, and the third group has the same number and shape as the first group. The end of the pull rope away from the slide plate is fixedly connected to the inside of the drain pipe, and the end of the pull rope away from the slide plate is made of elastic material. During operation, the shape of the three groups of ice-breaking blocks allows the cylinder to be stably maintained in the middle of the drain pipe, ensuring that the ice-breaking blocks can fully impact the frozen water when moving. At the same time, the elastic material at the end of the pull rope can pull the cylinder and ice-breaking blocks back to their original positions under the elastic action after the slide plate returns to its original position, achieving a repeated ice-breaking effect.

[0012] Preferably, the outer side of the extrusion block is provided with a speed bump, the inner side of the speed bump is hollow, the speed bump is made of flexible material, and the cross-section of the extrusion block is arranged in an isosceles triangle. During operation, the flexible speed bump is placed on the outer side of the extrusion block, and the bottom surface of the speed bump is fixed to the tunnel ground. Vehicles will run over the bottom surface of the speed bump. Combined with the isosceles triangle arrangement of the extrusion block, the extrusion process can be made smoother. It can not only achieve the effect of ordinary deceleration, reminding vehicles to pass slowly in the tunnel, but also serve as a power source to break up icy water.

[0013] Preferably, a protective tube is fixedly installed on the outer side of the receiving base, and the pull rope is located inside the protective tube. The two protective tubes and two pull ropes are arranged in a centrally symmetrical manner. The protective tube is connected to the drain pipe. During operation, the protective tube protects the pull rope and reduces damage to the pull rope from the external environment. The centrally opposite arrangement of the two sets of protective tubes and pull ropes allows the power transmitted by the two speed bumps to be transmitted to the pull ropes in the two drain pipes on both sides of the receiving base, thereby increasing the range of force application and allowing the ice-breaking effect to fill the entire drain pipe.

[0014] Preferably, a scraper is provided on the outer side of the filter screen, and a drive motor is fixedly installed on the inner side of each of the two extension boxes. A connecting rope is wound between the output ends of the two drive motors, and the middle part of the connecting rope is fixedly connected to the middle part of the scraper. The inner bottom surface of the accumulation tray is arc-shaped. During operation, to filter particles on the outer side of the filter screen, one of the drive motors can be started, and the scraper can be pulled horizontally on the outer side of the filter screen through the connecting rope, so that the filtered particles can be transferred to one side of the accumulation tray. By setting two drive motors, the scraper can move back and forth, realizing the effect of reciprocating transfer of particles, ensuring that the filter screen can filter particles efficiently.

[0015] Preferably, the cross-sectional shape of the scraper is the same as that of the filter screen, and a slider is fixedly installed on the inner side of the scraper. The slider is slidably connected to the outer side of the filter screen. During operation, the slider is designed to keep the scraper in contact with the outer side of the filter screen, so that the particle removal effect is maintained at the best.

[0016] Preferably, the scraper includes a rigid plate, with flexible strips fixedly installed at both ends of the rigid plate. The connecting rope is fixedly connected to the rigid plate. The flexible strips are made of elastic material. During operation, because the bottom of the inner side of the accumulation pan is arc-shaped, this design allows temporarily stored water to be quickly discharged through the drain pipe when idle. Combined with the flexible strips, the scraper can adapt to the curvature of the bottom surface of the accumulation pan and bend itself when moving, preventing jamming or incomplete scraping.

[0017] The beneficial effects of this invention are as follows:

[0018] 1. The present invention discloses a tunnel drainage structure for high-altitude and cold regions. By setting up a storage tray and a drainage pipe, the storage tray is buried in the soil of the tunnel, and the drain tray is placed in the center of the tunnel. A receiving component is laid along the direction of the tunnel. The water in the tunnel will fall into the storage tray through the drain tray and the receiving component, and then be discharged outward through the drainage pipe. The hollow space of the storage tray can play a buffering role. When a large amount of water rushes in from the outside, the storage tray can also store a large amount of water flow, and then slowly discharge it outward through the drainage pipe. This can effectively deal with sudden large amounts of water accumulation and reduce the problem of water accumulating on the tunnel surface for a long time.

[0019] 2. The tunnel drainage structure for high-altitude and cold regions described in this invention, in conjunction with the setting of ice-breaking blocks, uses a power component to drive a pulling rope to move a cylinder. When the cylinder moves, the ice-breaking blocks can break up the frozen water around it, thereby allowing the water to flow again, effectively reducing the problem of drainage failure caused by frozen water.

[0029] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0030] Example 1

[0031] like Figures 1 to 3 As shown in the embodiment of the present invention, a tunnel drainage structure for high-altitude and cold regions includes multiple receiving components 1. Each receiving component 1 includes an accumulation tray 11, the inner side of which is hollow. Drainage pipes 2 are fixedly connected to both sides of the accumulation tray 11. Adjacent receiving components 1 are connected by drainage pipes 2. A connecting ring 3 is fixedly installed on the outer side of the connection between two drainage pipes 2. Through holes 12 are provided on both sides of the accumulation tray 11, and the drainage pipes 2 communicate with the inner side of the accumulation tray 11 through the through holes 12. A receiving seat 5 is fixedly installed on the top surface of the accumulation tray 11, and a receiving seat 5 is fixedly installed on the top surface of the receiving seat 5. The drain pan 6 is vertically arranged with the receiving base 5. During operation, the accumulation pan 11 is buried in the soil of the tunnel, and the drain pan 6 is placed in the center of the tunnel. The receiving component 1 is laid along the direction of the tunnel. The water in the tunnel will fall into the accumulation pan 11 through the drain pan 6 and the receiving base 5, and then be discharged outward through the drain pipe 2. The hollow space of the accumulation pan 11 can play a buffering role. When a large amount of water rushes in from the outside, the accumulation pan 11 can also store a large amount of water flow, and then slowly discharge it outward through the drain pipe 2. This can effectively deal with sudden large amounts of water accumulation and reduce the problem of water accumulating on the tunnel surface for a long time.

[0032] like Figures 3 to 6As shown, a pull rope 16 is provided in the middle of the inner side of the drainage pipe 2. A cylinder 15 is fixedly installed on the outer side of the pull rope 16. Several ice-breaking blocks 22 are fixedly installed on the outer side of the cylinder 15. The ice-breaking blocks 22 are cylindrical. A power component is provided at the end of the pull rope 16. The power component is used to pull the pull rope 16. When working, the soil temperature in high-altitude and cold regions is low, which can easily cause the slowly drained water to freeze, causing the drainage structure to be blocked. With the setting of the ice-breaking blocks 22, the pull rope 16 is moved by the power component, which can pull the cylinder 15 to move. When the cylinder 15 moves, the ice-breaking blocks 22 can break the frozen water around it, so that the water can flow again, effectively reducing the problem of drainage failure caused by frozen water.

[0033] like Figure 3 As shown, a filter screen 13 is fixedly installed in the middle of the inner side of the accumulation tray 11. The filter screen 13 consists of three perforated plates, two of which are symmetrically arranged. The tops of the two perforated plates are fixedly connected by a third perforated plate, which is concave downwards. During operation, foreign particles are easily mixed into the accumulated water, which can easily cause blockage of the drain pipe 2. The water rich in impurities is also more likely to freeze. With the filter screen 13, the accumulated water falling from top to bottom can be filtered, and the particles in the water can be filtered onto the perforated plate on the top surface. At the same time, the naturally flowing water can also be blocked and filtered by the two perforated plates on the side, which effectively reduces the number of particles in the water. This reduces the problem of blockage of the drain pipe 2 caused by particle accumulation, and also makes the water flow cleaner. Reducing the number of particles in the water reduces the number of crystal nuclei that can adhere to when the water freezes, which can slow down the freezing speed.

[0034] like Figures 4 to 5As shown, the power assembly includes a sliding plate 18. Extension boxes 9 are fixedly connected to both sides of the storage tray 11. The inner side of the extension box 9 is hollow. The sliding plate 18 is slidably connected to the inner side of the extension box 9. Two transmission grooves 20 are formed on the top surface of the sliding plate 18. Two holes are formed on the top surface of the receiving seat 5. A bending rod 17 is slidably connected to the inner side of the holes. The bottom end of the bending rod 17 passes through the transmission grooves 20. One end of the pulling rope 16 is fixedly connected to the outer side of the sliding plate 18. A long plate is fixedly installed on the outer side of the bending rod 17 near its top. A spring 8 is fixedly installed on the long plate and the top surface of the receiving seat 5. The sliding plate 18 is fixedly connected to the inner side of the receiving seat 5. A spring 21 is connected to the top of each of the two curved rods 17, and a pressing block 24 is fixedly connected to the top of each of them. During operation, the pressing block 24 is placed on the tunnel surface. When a vehicle passes by, the pressing block 24 is pressed down, thereby continuously pressing the curved rods 17. The pressing down of the curved rods 17 will drive the slide plate 18 to move to one side, thereby pulling the pulling rope 16, which will move the ice-breaking block 22. After the vehicle passes, the spring 8 rebounds, and the spring 21 pushes out, allowing the slide plate 18 to return to its position. Through this setting, the movement of the cylinder 15 and the ice-breaking block 22 is achieved without consuming other energy. At the same time, the overall structure is a mechanical transmission, which reduces the failure rate compared to using electronic equipment.

[0035] like Figures 5 to 6 As shown, the ice-breaking blocks 22 are divided into three groups, which are equidistantly distributed on the outside of the cylinder 15. The first group has five ice-breaking blocks 22, which are arranged in a equidistant ring. The ends of the ice-breaking blocks 22 are attached to the inner wall of the drain pipe 2. The second group has three ice-breaking blocks 22. The third group has the same number and shape as the first group. The end of the pull rope 16 away from the slide plate 18 is fixedly connected to the inside of the drain pipe 2. The end of the pull rope 16 away from the slide plate 18 is made of elastic material. During operation, the shape of the three groups of ice-breaking blocks 22 is combined to keep the cylinder 15 stably in the middle of the drain pipe 2, ensuring that the ice-breaking blocks 22 can fully impact the frozen water when moving. At the same time, the elastic material at the end of the pull rope 16 can pull the cylinder 15 and the ice-breaking blocks 22 back to their original positions under the action of elasticity after the slide plate 18 returns to its original position, thus achieving a repeated ice-breaking effect.

[0036] like Figures 2 to 5As shown, a speed bump 7 is provided on the outer side of the extrusion block 24. The inner side of the speed bump 7 is hollow. The speed bump 7 is made of flexible material. The cross-section of the extrusion block 24 is an isosceles triangle. During operation, the flexible speed bump 7 is placed on the outer side of the extrusion block 24, and the bottom surface of the speed bump 7 is fixed to the tunnel floor. Vehicles will run over the bottom surface of the speed bump 7. Combined with the isosceles triangle shape of the extrusion block 24, the extrusion process can be made smoother. It can achieve the effect of ordinary deceleration, reminding vehicles to pass slowly in the tunnel, and at the same time, it can also serve as a power source to break up the icy water.

[0037] like Figures 2 to 4 As shown, a protective tube 10 is fixedly installed on the outer side of the receiving base 5, and the pull rope 16 is located inside the protective tube 10. The two protective tubes 10 and the two pull ropes 16 are arranged in a centrally symmetrical manner. The protective tube 10 is connected to the drain pipe 2. During operation, the protective tube 10 protects the pull rope 16 and reduces the damage to the pull rope 16 caused by the external environment. The two sets of protective tubes 10 and pull ropes 16 are arranged on opposite sides of the center, so that the power transmitted by the two speed bumps 7 can be transmitted to the pull ropes 16 in the two drain pipes 2 on both sides of the receiving base 5, thereby increasing the range of force action and allowing the ice-breaking effect to fill the entire drain pipe 2.

[0038] like Figure 3 As shown, a scraper 14 is provided on the outer side of the filter screen 13, and a drive motor is fixedly installed on the inner side of each of the two extension boxes 9. A connecting rope 23 is wound and connected between the output ends of the two drive motors. The middle part of the connecting rope 23 is fixedly connected to the middle part of the scraper 14. The inner bottom surface of the accumulation tray 11 is arc-shaped. When working, to filter particles on the outer side of the filter screen 13, one of the drive motors can be started, and the scraper 14 can be pulled horizontally on the outer side of the filter screen 13 through the connecting rope 23. The filtered particles can be transferred to one side of the accumulation tray 11. With the setting of two drive motors, the scraper 14 can move back and forth, realizing the effect of reciprocating transfer of particles, ensuring that the filter screen 13 can filter particles efficiently.

[0039] like Figure 3 As shown, the cross-sectional shape of the scraper 14 is the same as that of the filter screen 13. A slider is fixedly installed on the inner side of the scraper 14. The slider is slidably connected to the outer side of the filter screen 13. During operation, the slider is designed to keep the scraper 14 in contact with the outer side of the filter screen 13, so that the particle removal effect is maintained at the best.

[0040] Example 2

[0041] like Figure 7As shown in the comparative embodiment one, another embodiment of the present invention is as follows: the scraper 14 includes a hard plate 25, and flexible strips 26 are fixedly installed at both ends of the hard plate 25. The connecting rope 23 is fixedly connected to the hard plate 25. The flexible strips 26 are made of elastic material. During operation, since the bottom of the inner side of the accumulation pan 11 is arc-shaped, this setting allows the temporarily stored water to be quickly discharged through the drain pipe 2 when idle. With the setting of the flexible strips 26, when the scraper 14 moves, the flexible strips 26 can bend to adapt to the curvature of the bottom surface of the accumulation pan 11, and there will be no jamming or incomplete scraping.

[0042] During operation, the accumulation pan 11 is buried in the tunnel soil, and the drain pan 6 is placed in the center of the tunnel. The receiving assembly 1 is laid along the tunnel direction. Water in the tunnel flows through the drain pan 6 and the receiving base 5 into the accumulation pan 11, and then is discharged outwards through the drain pipe 2. The hollow space of the accumulation pan 11 acts as a buffer, storing a large amount of water when it floods in, and then slowly discharging it outwards through the drain pipe 2. This effectively handles sudden large-scale water inflows and reduces the problem of water accumulating on the tunnel surface for extended periods. In cold regions, the low soil temperature can easily cause the slowly draining water to freeze, clogging the drainage structure. The use of ice-breaking blocks 22 helps to prevent this. The power unit drives the pull rope 16 to move, which in turn moves the cylinder 15. As the cylinder 15 moves, the ice-breaking block 22 breaks up the surrounding frozen water, allowing it to flow again and effectively reducing drainage failure caused by frozen water. The water easily contains foreign particles, which can easily clog the drain pipe 2, and the impurity-rich water is also more prone to freezing. With the filter screen 13, its structure filters water falling from above, trapping particles on the top perforated plate. Simultaneously, naturally flowing water is blocked and filtered by the two side perforated plates, effectively reducing the number of particles in the water and minimizing the problem of particle accumulation causing drain pipe 2 blockage. This design also makes the water flow cleaner, reducing the number of particles in the water and decreasing the number of crystal nuclei that can adhere to when the water freezes, thus slowing down the freezing process. By placing the extrusion block 24 on the tunnel surface, when a vehicle passes by, it presses down on the extrusion block 24, thereby continuously compressing the bending rod 17. The downward pressure of the bending rod 17 causes the sliding plate 18 to move to one side, which in turn pulls the pulling rope 16, thus moving the ice-breaking block 22. After the vehicle passes, the spring 18 rebounds, and the spring 21 pushes it out, causing the sliding plate 18 to return to its original position. Through this design, the movement of the cylinder 15 and the ice-breaking block 22 is achieved without consuming any other energy. In addition, the overall structure is a mechanical transmission, which reduces the failure rate compared to using electronic equipment. The three sets of ice-breaking blocks 22 are designed to ensure that the cylinder 15 can be stably maintained in the middle of the drain pipe 2, so that the ice-breaking blocks 22 can fully impact the frozen water when moving. At the same time, the elastic material at the end of the rope 16 can pull the cylinder 15 and the ice-breaking blocks 22 back to their original positions under the elastic action after the slide plate 18 returns to its original position, thus achieving repeated ice-breaking effect. The flexible speed bump 7 is placed on the outside of the extrusion block 24 and the bottom surface of the speed bump 7 is fixed to the tunnel ground. Vehicles will run over the bottom surface of the speed bump 7. Combined with the isosceles triangle design of the extrusion block 24, the extrusion process can be made smoother. It can not only achieve the effect of ordinary deceleration, reminding vehicles to pass through the tunnel slowly, but also serve as a power source to break the frozen water.The protective tube 10 protects the pull rope 16, reducing damage to it from the external environment. The two sets of protective tubes 10 and pull ropes 16 are positioned opposite each other, allowing the power transmitted from the two speed bumps 7 to be transferred to the pull ropes 16 in the two drain pipes 2 on both sides of the receiving seat 5. This increases the range of force application, ensuring the ice-breaking effect covers the entire drain pipe 2. To filter particles outside the filter screen 13, one of the drive motors can be activated, pulling the scraper 14 horizontally outside the filter screen 13 via the connecting rope 23. This transfers the filtered particles to one side of the accumulation tray 11. The two drive motors... The motor allows the scraper 14 to move back and forth, achieving a reciprocating transfer of particles and ensuring that the filter screen 13 can efficiently filter particles. Combined with the slider, the scraper 14 remains in contact with the outer side of the filter screen 13, maintaining optimal particle removal. The curved bottom of the collection tray 11 allows temporarily stored water to be quickly drained through the drain pipe 2 when idle. The flexible strip 26, when the scraper 14 moves, adapts to the curvature of the bottom surface of the collection tray 11, preventing jamming or incomplete removal.
