Description

Technical Field

[0001] The present invention relates to the field of tracks. More specifically, the present invention relates to a track structure. Background Art

[0002] In modern railway transportation systems, the stability and durability of track structures play a crucial role in ensuring the safe and efficient operation of trains. With the continuous development of railway transportation, the running speed and load capacity of trains have been continuously increasing, which poses higher requirements for track structures.

[0003] Traditional track structures have obvious defects in dealing with moisture erosion. For example, the joints between track slabs are usually treated with simple sealing materials. Under the influence of factors such as long-term train vibration, temperature changes, and rainwater scouring, these materials are prone to aging and cracking, resulting in moisture penetration into the track structure. Once moisture penetrates, it will cause problems such as corrosion of the steel bars in the track slabs and deterioration of the concrete, seriously reducing the load-bearing capacity and service life of the track structure and increasing the safety hazards of railway operations.

[0004] In addition, in terms of track maintenance and inspection, the existing technical means are relatively backward. Most rely on manual regular inspections to discover problems with track structures. This method is not only inefficient but also difficult to detect some hidden problems, such as fine cracks in the sealing materials. By the time the problems are discovered when they have developed to a more serious level, a large amount of manpower and material resources often need to be invested in repairs, and it may even lead to the interruption of railway transportation, causing greater losses to the economy and society.

[0029] As Figures 1 to 4 shown, an embodiment of the present invention provides a track structure, including: a first track plate 1, a second track plate 2, and a joint provided between the two. The joint includes an upper joint and a lower joint that are vertically arranged and communicate with each other. The inner wall and bottom of the joint are provided with a waterproof coiled material layer. The upper joint is filled with a first rubber strip 3 and a permeable concrete layer 4 in sequence from top to bottom. The top of the first rubber strip 3 protrudes from the upper joint and is detachably connected to the top surfaces of the first track plate 1 and the second track plate 2. The lower joint is filled with a second rubber strip 5. A diversion groove 6 is provided on the top surface of the second rubber strip 5. The diversion groove 6 is inclined along the length direction of the joint, and the high end of the diversion groove 6 is closed, and a water collection tank 7 is detachably connected to the low end. A drain pipe 8 is provided at the bottom of the water collection tank 7, and a flow sensor 9 is provided in the drain pipe 8. Among them, the flow sensor 9 is connected to a remote control system. The remote control system is used to judge the crack rate of the first rubber strip 3 according to the detection value of the flow sensor 9 and the real-time rainfall. When the crack rate is greater than a preset threshold, a notice to replace the first rubber strip 3 is generated and sent to the maintenance end.

[0030] In the above embodiment, the track structure includes: a first track slab 1 and a second track slab 2. These two track slabs are made of high-strength prestressed concrete and can withstand the huge pressure and impact force during train operation. A joint is provided between the first track slab 1 and the second track slab 2. The joint includes an upper joint and a lower joint which are arranged vertically and communicate with each other. To effectively prevent moisture from penetrating and eroding the track structure, a waterproof coiled material layer is laid on the inner wall and bottom of the joint. The waterproof coiled material layer has good weather resistance, flexibility and waterproofness, and can work stably for a long time in various complex environments. The upper joint is filled with a first rubber strip 3 and a permeable concrete layer 4 from top to bottom in sequence. The first rubber strip 3 is made of ethylene propylene diene monomer (EPDM) rubber. The top of the first rubber strip 3 protrudes from the upper joint and is detachably connected to the top surfaces of the first track slab 1 and the second track slab 2. The detachable connection methods include but are not limited to bonding and clamping. This not only facilitates installation and replacement but also ensures good sealing and waterproof effects. The permeable concrete layer 4 uses permeable concrete with a strength grade of C30, which can not only ensure a certain structural strength but also allow the water infiltrated through the cracked first rubber strip 3 to seep down smoothly. The lower joint is filled with a second rubber strip 5, which is also made of EPDM rubber. A diversion groove 6 is provided on the top surface of the second rubber strip 5. The diversion groove 6 is inclined along the length direction of the joint. Preferably, the inclination angle is 3° - 15°. And the high end of the diversion groove 6 is closed, and the low end is detachably connected with a water collecting tank 7 through a quick connection buckle. The water collecting tank 7 is made of stainless steel, which is firm, durable and not easy to rust. A drain pipe 8 is provided at the bottom of the water collecting tank 7, and a high-precision flow sensor 9 is provided in the drain pipe 8. The flow sensor 9 can accurately detect the drainage flow rate. Among them, the flow sensor 9 is connected to the remote control system through a wireless transmission module. The remote control system is built-in with a crack rate analysis algorithm for judging the crack rate of the first rubber strip 3 according to the detection value of the flow sensor 9 and the real-time rainfall. When the crack rate is greater than a preset threshold (such as 10%), the remote control system immediately generates a notice to replace the first rubber strip 3 and sends it to the maintenance end through text message or a dedicated maintenance management software.

[0031] The track structure of the present invention adopts a split-type drainage mechanism. The upper joint adopts a double-layer structure of a first rubber strip and a permeable concrete layer: the first rubber strip, as an elastic sealing layer, can effectively prevent surface water from invading, and the permeable concrete layer allows the water infiltrating through the cracked first rubber strip to seep downward through its internal pores. The second rubber strip of the lower joint forms a directional drainage channel through an inclined diversion groove, and uses the gravity to direct the infiltrated water to the water collection tank. This layered drainage design enables the joint to have a dual protection ability of "first blocking and then guiding", effectively extending the waterproof life of the joint; the drainage volume is monitored in real time through a flow sensor, the remote control system synchronously accesses the real-time rainfall data of the meteorological bureau, and calculates the crack rate of the first rubber strip according to the drainage volume and the real-time rainfall data. When the crack rate is greater than the preset threshold, the system automatically generates a notice to replace the first rubber strip and sends it to the maintenance end. Compared with the traditional manual inspection, it realizes the real-time monitoring and intelligent analysis of the sealing state of the joint, and can timely discover and warn potential problems; the first rubber strip and the top surface of the track are detachably connected, and the replacement can be completed within 15 minutes by a special tool during maintenance, which is convenient for maintenance.

[0032] In another embodiment, the waterproof coiled material layer includes a first rubber protection layer 10 connected to the inner wall of the joint and a waterproof coiled material 11 provided thereon.

[0033] In the above embodiment, the waterproof coiled material layer includes a first rubber protection layer 10 tightly connected to the inner wall of the joint and a waterproof coiled material 11 provided thereon. The first rubber protection layer 10 is made of ethylene propylene diene monomer rubber, with a thickness of 5 to 10 millimeters, and is firmly bonded to the inner wall of the joint through a special waterproof adhesive. During the operation of the train, due to the continuous impact of the wheels and the track, the track slab will vibrate to a certain extent, which will cause the joint to deform. At this time, the first rubber protection layer 10 can effectively buffer this deformation. When the track slab has fine cracks due to various factors, the first rubber protection layer 10 can prevent the waterproof coiled material 11 from directly contacting the cracked part of the track slab, thereby preventing the waterproof coiled material 11 from being torn or damaged due to the cracking of the track slab, ensuring that the waterproof coiled material layer can play a waterproof role stably for a long time. The waterproof coiled material 11 is selected as an SBS modified asphalt waterproof coiled material, which has good weather resistance, flexibility and waterproofness, and can maintain stable waterproof performance under different temperature and humidity conditions.

[0034] In another embodiment, a second rubber protection layer 12 is provided on the waterproof coiled material 11 located in the upper joint.

[0035] In the above embodiment, a second rubber protective layer 12 is provided on the waterproof coiled material 11 located within the upper joint. The second rubber protective layer 12 is made of ethylene propylene diene monomer (EPDM) rubber, with a thickness of 3 to 5 millimeters. Its shape is designed to fit the upper joint, covering the waterproof coiled material 11 and extending to both sides capable of shielding the second rubber strip 3. First, the second rubber protective layer 12 plays a key role in isolating the water-seeping concrete layer 4 and the waterproof coiled material layer to protect the waterproof coiled material 11. Second, in terms of waterproofing, the second rubber protective layer 12 can shield both sides of the second rubber strip 3, preventing water from entering the gap between the second rubber strip and the waterproof coiled material layer, preventing water accumulation within the joint. At the same time, it can make the water seeping through the water-seeping concrete layer flow into the diversion groove, improving the accuracy of crack rate calculation.

[0036] In another embodiment, the surfaces of the first rubber protective layer 10 and the second rubber protective layer 12 in contact with the waterproof coiled material are both serrated surfaces, and the serrated surfaces on the first rubber protective layer 10 and the second rubber protective layer 12 are engaged with each other.

[0037] In the above embodiment, the surfaces of the first rubber protective layer 10 and the second rubber protective layer 12 in contact with the waterproof coiled material are both designed as serrated surfaces. Firstly, the serrated surfaces increase the contact area and friction with the waterproof coiled material, making the connection between the first rubber protective layer 10, the second rubber protective layer 12 and the waterproof coiled material more stable. Even under the strong vibration and complex stress environment generated during the long-term operation of the train, it can effectively prevent relative displacement among the three. Moreover, the engagement structure helps to disperse the stress that may occur at the joint, reducing the risk of cracking caused by material aging or external forces. Secondly, the mutually engaged serrated surfaces form multiple labyrinth-like waterproof paths. When moisture attempts to penetrate, it will be continuously blocked in these intricate serrated gaps, greatly delaying the penetration speed of the moisture, and even being able to completely block the moisture, preventing it from damaging the waterproof coiled material, and further ensuring the long-term stable waterproofing effect of the waterproof coiled material layer.

[0038] In another embodiment, the lower part of the upper joint is inclined towards the side close to the center line of the joint, and the water-seeping concrete layer 4 is filled on the second rubber protective layer 12 in the lower part and the middle part of the upper joint.

[0039] In the above embodiment, the lower part of the upper joint is inclined towards the side close to the center line of the joint, and the permeable concrete layer 4 is filled on the lower part and the middle part of the second rubber protective layer 12 of the upper joint. The inclined setting of the upper joint helps to guide the water that may seep into the joint along a specific path, making it easier for the water to be guided to the middle part of the joint under the action of gravity and finally flow into the diversion groove, effectively avoiding the accumulation of water in the joint, thereby reducing corrosion, swelling or other potential damages caused by water retention; the permeable concrete layer 4 filled on the second rubber protective layer 12, while ensuring the strength of the track structure, uses its water-permeable property to guide the water to penetrate downward, and the second rubber protective layer 12 can effectively block the lateral penetration of water and avoid damaging the waterproof coiled material 11.

[0040] In another embodiment, step surfaces are provided on both sides of the top surface of the second rubber strip 5, the step surfaces are connected to the bottom surface of the second rubber protective layer 12, and a permeable isolation layer plate 13 is placed on the step surfaces, and the diversion groove 6 is arranged below the permeable isolation layer plate 13.

[0041] In the above embodiment, step surfaces are provided on both sides of the top surface of the second rubber strip 5, and the step surfaces are hermetically connected to the bottom surface of the second rubber protective layer 12 using a special adhesive to ensure seamless fitting between the two, effectively preventing water from penetrating into the gap between the second rubber strip 5, the second rubber protective layer 12 and the waterproof coiled material 11, and further improving the waterproof performance; a permeable isolation layer plate 13 is placed on the step surfaces, and the permeable isolation layer plate 13 is made of a high-strength and high-water-permeable polypropylene fiber-reinforced composite material. It has a porous structure that allows water to pass through smoothly. At the same time, its high-strength property enables it to effectively separate and support the permeable concrete layer located above. When a small amount of water seeps downward through the permeable concrete layer, the permeable isolation layer plate 13 can quickly guide the water to the diversion groove 6 below and quickly and efficiently drain the water to the water collection tank through the inclined diversion groove 6, avoiding the accumulation of water inside the track structure.

[0042] In another embodiment, the first rubber strip 3 includes an integrally formed head and tail. The head is semi-cylindrical, and both sides of the head are detachably connected to the top surfaces of the first track 1 plate and the second track plate 2, and the tail is perpendicular to the head and filled in the upper part of the upper joint.

[0043] In the above embodiment, the first rubber strip 3 includes a head and a tail that are integrally formed. The head is designed as a semi-cylindrical shape, and both sides of the head are detachably connected to the top surfaces of the first track slab 1 and the second track slab 2, facilitating the disassembly operation by maintenance personnel in the later stage with simple tools, reducing the maintenance cost and time. The tail is perpendicular to the head and is filled in the upper part of the upper joint. After filling, the tail can effectively adapt to the shape change of the upper joint and still maintain good sealing performance under the vibration and pressure generated during train operation, preventing moisture from seeping into the joint from the upper part of the upper joint.

[0044] In another embodiment, on one side of the top surfaces of the first track slab 1 and the second track slab 2 close to the joint, there are provided bosses 14. In the middle of the bosses 14, a plurality of positioning bumps 15 are provided at intervals along the length direction. On both sides of the bottom surface of the head, a plurality of positioning grooves are provided at intervals along its length direction, and the positioning grooves are engaged with the positioning bumps 15 in a snap-fit manner.

[0045] In the above embodiments, on one side of the top surfaces of the first track slab 1 and the second track slab 2 close to the joint, there are both convex platforms 14. The convex platforms 14 are made of the same high-strength prestressed concrete material as the track slab and are integrally formed during the casting process of the track slab, ensuring their close combination with the track slab and structural stability. The height of the convex platform 14 is preferably 20 mm, and the width is preferably 30 mm. Such dimensions can effectively block the accumulated water on the top surface of the track slab without affecting the normal operation of the track and the installation of other components. When there is accumulated water on the top surface of the track slab, the convex platform 14 can act like a dam to intercept the accumulated water on the side away from the joint, preventing the accumulated water from entering the joint through the gap between the first rubber strip and the joint; along the length direction of the middle part of the convex platform 14, a plurality of positioning bumps 15 are arranged at intervals. The positioning bumps 15 are also made of high-strength prestressed concrete material and are synchronously formed by a precise mold during the casting of the convex platform 14. The height of each positioning bump 15 is preferably 8 mm, the width is preferably 10 mm, and the spacing between adjacent positioning bumps 15 is preferably 150 mm, so as to ensure that the positioning bumps 15 have sufficient strength and can achieve precise positioning and connection with the first rubber strip; on both sides of the bottom surface of the head of the first rubber strip 3, a plurality of positioning grooves are arranged at intervals along its length direction. These positioning grooves are precisely matched with the dimensions and positions of the positioning bumps 15. When installing the first rubber strip 3, only need to align the positioning grooves on the bottom surface of the head with the positioning bumps 15 on the convex platform 14 and gently press to achieve the mating and clamping of the two. This clamping method is easy to operate without the need for complex tools and processes, greatly improving the installation efficiency. At the same time, due to the tight fit between the positioning bumps 15 and the positioning grooves, the connection between the first rubber strip 3 and the track slab is firm and reliable. Under the action of complex external forces such as vibration and impact generated during the train operation, it can also ensure that the first rubber strip 3 will not be displaced or fall off. The spaced arrangement of the plurality of positioning bumps 15 also plays a role in precise positioning, ensuring that the first rubber strip 3 is always in the correct position during installation and avoiding the decline of the waterproof and sealing effects caused by installation deviation.

[0046] Furthermore, the waterproof coiled material 11 located at the top of the upper joint extends upward and turns outward to be connected to the surface of the convex platform 14 to prevent water from seeping into the gap between the first rubber protection layer 10 and the upper joint, further improving the waterproof effect of the joint.

[0047] In another embodiment, the crack rate calculation formula of the first rubber strip 3 is as follows:

[0048]

[0049] In the formula, η is the crack rate, %; Q is the detection value of the flow sensor 9, m³ / h; A is the cross-sectional area of the joint, m 2; R is the real-time rainfall, in mm / h; β is the seepage correction factor, with a value range of 0 < β ≤ 1.

[0050] Algorithm steps:

[0051] 1. Data collection:

[0052] Obtain the detection values Q and rainfall R of the flow sensor in real time.

[0053] Input parameters: A, β.

[0054] 2. Crack rate calculation:

[0055] If Q = 0 and R > 0, then η = 0.

[0056] If Q > 0, then:

[0057]

[0058] Among them, β needs to be determined by the following methods:

[0059] Laboratory calibration: Simulate different crack rates (η) and rainfall (R) in the laboratory, measure the actual Q value, and determine the value of β.

[0060] Dynamic correction: Introduce historical data to train a regression model and automatically correct the value of β.

[0061] 3. Threshold judgment

[0062] When η > the preset threshold (such as 10%), trigger a maintenance notice.

[0063] In another embodiment, the low end of the diversion groove 6 protrudes from the end face of the lower joint; the water collection tank 7 includes a cuboid tank arranged coaxially and a quadrangular pyramid tank arranged below it. The top of the cuboid tank is connected to the permeable concrete layer 4 through a connecting plate 16 and bolts 17. The side wall of the cuboid tank is provided with a socket for plugging and matching with the protruding end of the second rubber strip 5. The bottom of the quadrangular pyramid tank is provided with the drain pipe 8. The drain pipe 8 extends below the filter plate 18 through a rubber sleeve 19 and an opening 20 preset on the filter plate 18. The filter plate 18 is horizontally arranged in the drainage ditches 21 on both sides of the track slab.

[0064] In the above embodiments, the low end of the diversion groove 6 protrudes from the end face of the lower joint seam to ensure that the water drained through the diversion groove 6 flows into the water collecting tank 7 unobstructed, avoiding water accumulation caused by poor water flow paths and further improving the drainage efficiency; the water collecting tank 7 is composed of a cuboid tank arranged coaxially and a quadrangular pyramid tank located below it. The top of the cuboid tank is tightly connected to the permeable concrete layer 4 through the connecting plate 16 and the high-strength bolt 17. The connecting plate 16 is made of Q345 high-strength steel and has excellent tensile and compressive properties, which can effectively withstand various forces generated during the process of the water collecting tank 7 collecting water. The bolt 17 is an 8.8-grade high-strength bolt to ensure the stability of the connection. Even under the strong vibration and impact caused by the train operation, the connection between the water collecting tank 7 and the permeable concrete layer 4 can be guaranteed not to loosen; the side wall of the cuboid tank is provided with a socket specifically for plugging and matching with the protruding end of the second rubber strip 5. The size of the socket matches the protruding end of the second rubber strip 5. After the two are tightly plugged, it not only effectively prevents water from leaking from the connection between the water collecting tank 7 and the second rubber strip 5, but also further enhances the stability of the water collecting tank 7 in the track structure; a drain pipe 8 is provided at the bottom of the quadrangular pyramid tank. The drain pipe 8 extends below the filter plate 18 through the rubber sleeve 19 and the opening 20 pre-installed on the filter plate 18. The filter plate 18 is made of corrosion-resistant stainless steel, and fine filter holes are evenly distributed on the surface, which can effectively filter impurities in the water and prevent them from entering the drainage ditch and causing blockage; the rubber sleeve 19 is made of high-elasticity and wear-resistant natural rubber. It not only plays a good supporting role for the drain pipe 8, but also can effectively reduce the vibration generated by the water collecting tank 7 under the action of water flow impact and train vibration by virtue of its own elasticity. Since the flow sensor 9 is installed on the drain pipe 8, the vibration damping effect of the rubber sleeve 19 can prevent the vibration of the water collecting tank 7 from being transmitted to the flow sensor 9, thereby protecting the precision components of the flow sensor 9 from damage and ensuring that it can detect the drainage flow stably and accurately for a long time, providing reliable data support for the remote control system and ensuring the smooth progress of the drainage monitoring and maintenance work of the entire track structure.
