Description

[0001] The present invention relates to the field of tracks, and more particularly to a track structure. Background Art

[0002] In modern railway transportation systems, the stability and durability of track structures play a vital role in ensuring the safe and efficient operation of trains. With the continuous development of railway transportation, the running speed and load-bearing capacity of trains continue to increase, which puts higher requirements on track structures.

[0003] Traditional track structures have obvious defects in dealing with water erosion. For example, the joints between track plates are usually treated with simple sealing materials. These materials are prone to aging and cracking under the influence of long-term train vibration, temperature changes, and rain erosion, causing moisture to penetrate into the track structure. Once moisture penetrates, it will cause problems such as steel corrosion and concrete deterioration of the track plate, seriously reducing the bearing capacity and service life of the track structure, and increasing safety risks in railway operations.

[0004] In addition, in terms of track maintenance and inspection, the existing technical means are relatively backward. Most of them rely on regular manual inspections to detect track structure problems. This method is not only inefficient, but also difficult to detect some hidden problems in time, such as fine cracks in sealing materials. When the problem develops to a more serious level before being discovered, it often requires a lot of manpower and material resources to repair it, and it may even cause the interruption of railway transportation, causing great losses to the economy and society.

[0023] like Figure 1~Figure 4 As shown, an embodiment of the present invention provides a track structure, comprising: a first track plate 1, a second track plate 2 and a joint arranged therebetween, the joint comprising an upper joint and a lower joint arranged up and down and connected, the inner wall and bottom of the joint are paved with a waterproof roll material layer, the upper joint is filled with a first rubber strip 3 and a permeable concrete layer 4 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, the top of the second rubber strip 5 is A guide groove 6 is provided on the surface, and the guide groove 6 is inclined along the length direction of the joint, and the high end of the guide groove 6 is closed, and the low end is detachably connected to a water collecting tank 7, and a drain pipe 8 is provided at the bottom of the water collecting tank 7, and a flow sensor 9 is provided in the drain pipe 8, wherein the flow sensor 9 is connected to a remote control system, and 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, and when the crack rate is greater than a preset threshold value, a notification of replacing the first rubber strip 3 is generated and sent to the maintenance end.

[0024] In the above embodiment, the track structure includes: a first track plate 1 and a second track plate 2. The two track plates are made of high-strength prestressed concrete material and can withstand the huge pressure and impact force during train operation. A joint is arranged between the first track plate 1 and the second track plate 2, and the joint includes an upper joint and a lower joint arranged up and down and interconnected. In order to effectively prevent moisture from penetrating and corroding the track structure, a layer of waterproof roll material is laid on the inner wall and bottom of the joint. The waterproof roll 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. The first rubber strip 3 is made of EPDM rubber. The top of the first rubber strip 3 protrudes from the upper joint and is detachably connected to the top surface of the first track plate 1 and the second track plate 2. The detachable connection method includes but is not limited to bonding and clamping, which is convenient for installation and replacement and can ensure a good sealing and waterproof effect. The permeable concrete layer 4 is made of permeable concrete with a strength grade of C30, which can not only ensure a certain structural strength, but also allow the water that penetrates through the cracked first rubber strip 3 to penetrate smoothly. The lower joint is filled with a second rubber strip 5, which is also made of EPDM rubber. The top surface of the second rubber strip 5 is provided with a guide groove 6, which is inclined along the length direction of the joint. Preferably, the inclination angle is 3°~15°, and the high end of the guide groove 6 is closed, and the low end is detachably connected to the water collection tank 7 through a quick connection buckle. The water collection tank 7 is made of stainless steel, which is durable and not easy to rust. A drain pipe 8 is provided at the bottom, and a high-precision flow sensor 9 is provided in the drain pipe 8. The flow sensor 9 can accurately detect the drainage flow. Among them, the flow sensor 9 is connected to the remote control system through a wireless transmission module, and the remote control system has a built-in 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 notification for replacing the first rubber strip 3 and sends it to the maintenance end via a text message or dedicated maintenance management software.

[0025] The track structure of the present invention adopts a split-slit drainage mechanism, and 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 block the intrusion of surface water, while the permeable concrete layer allows the water that penetrates through the cracked first rubber strip to penetrate through its internal pores, and the second rubber strip of the lower joint forms a directional drainage channel through an inclined diversion groove, and uses gravity to guide the infiltrated water to the water collection tank. This layered drainage design enables the joint to have a dual protection capability of "first blocking and then guiding", effectively extending the waterproof life of the joint; the drainage volume is monitored in real time by a flow sensor, and the remote control system is synchronously connected to the real-time rainfall data of the meteorological bureau, and the crack rate of the first rubber strip is calculated according to the drainage volume and the real-time rainfall data. When the crack rate is greater than a preset threshold, the system automatically generates a notification to replace the first rubber strip and sends it to the maintenance end. Compared with traditional manual inspections, real-time monitoring and intelligent analysis of the sealing state of the joint are realized, and potential problems can be discovered and warned in time; the first rubber strip and the top surface of the track are detachably connected, and can be replaced within 15 minutes by special tools during maintenance, which is convenient for maintenance.

[0026] In another embodiment, the waterproof roll material layer includes a first rubber protective layer 10 connected to the inner wall of the joint and a waterproof roll material 11 disposed thereon.

[0027] In the above embodiment, the waterproof roll material layer includes a first rubber protective layer 10 tightly connected to the inner wall of the joint and a waterproof roll material 11 arranged thereon. The first rubber protective layer 10 is made of EPDM rubber with a thickness of 5 to 10 mm, 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 plate will vibrate to a certain extent, which will cause the joint to deform. At this time, the first rubber protective layer 10 can effectively buffer this deformation. When the track plate has slight cracks due to various factors, the first rubber protective layer 10 can prevent the waterproof roll material 11 from directly fitting to the cracked part of the track plate, thereby preventing the waterproof roll material 11 from being torn or damaged due to the cracking of the track plate, ensuring that the waterproof roll material layer plays a waterproof role in a long-term and stable manner. The waterproof roll material 11 is made of SBS modified asphalt waterproof roll material, which has good weather resistance, flexibility and waterproofness, and can maintain stable waterproof performance under different temperature and humidity conditions.

[0028] In another embodiment, a second rubber protective layer 12 is provided on the waterproof coiled material 11 located in the upper seam.

[0029] In the above embodiment, a second rubber protective layer 12 is provided on the waterproofing membrane 11 located in the upper joint. The second rubber protective layer 12 is made of EPDM rubber, has a thickness of 3 to 5 mm, and is designed to fit the upper joint, covers the waterproofing membrane 11 and extends to shield both sides of the second rubber strip 3. First, the second rubber protective layer 12 plays a key role in isolating the permeable concrete layer 4 and the waterproofing membrane layer to protect the waterproofing membrane 11. Secondly, in terms of waterproofing, the second rubber protective layer 12 can shield both sides of the second rubber strip 3, prevent water from entering the gap between the second rubber strip and the waterproofing membrane layer, prevent water from accumulating in the joint, and at the same time, allow the water that seeps through the permeable concrete layer to flow into the diversion groove, thereby improving the accuracy of the crack rate calculation.

[0030] In another embodiment, the surfaces of the first rubber protective layer 10 and the second rubber protective layer 12 that are in contact with the waterproof membrane 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.

[0031] 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 designed to be serrated surfaces. First, the serrated surface increases 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 by the long-term operation of the train, it can effectively prevent the relative displacement between the three. The interlocking structure also helps to disperse the stress that may be generated at the joints and reduce the risk of cracking caused by material aging or external forces. Second, the interlocking serrated surfaces form multiple labyrinth-like waterproof paths. When water tries to penetrate, it will be constantly blocked in these intricate serrated gaps, greatly slowing down the penetration rate of water, and even completely blocking the water to avoid damage to the waterproof coiled material, further ensuring that the waterproof coiled material layer can play a long-term and stable waterproof role.

[0032] In another embodiment, the lower portion of the upper joint is inclined toward a side close to the center line of the joint, and the permeable concrete layer 4 is filled on the second rubber protective layer 12 at the lower and middle portions of the upper joint.

[0033] In the above embodiment, the lower part of the upper joint is tilted toward the side close to the center line of the joint, and the permeable concrete layer 4 is filled on the lower and middle second rubber protective layer 12 of the upper joint. The tilted upper joint helps to guide the water that may penetrate into the joint to flow along a specific path, so that the water is more easily guided to the middle of the joint under the action of gravity and finally flows into the guide groove, effectively avoiding the accumulation of water in the joint, thereby reducing corrosion, expansion or other potential damage caused by water retention; the permeable concrete layer 4 filled on the second rubber protective layer 12, on the basis of ensuring the strength of the track structure, uses its permeable characteristics to guide the water to penetrate downward, and the second rubber protective layer 12 can effectively block the lateral penetration of water to avoid damage to the waterproof membrane 11.

[0034] In another embodiment, stepped surfaces are provided on both sides of the top surface of the second rubber strip 5 , the stepped surfaces are connected to the bottom surface of the second rubber protective layer 12 , a water-permeable isolation layer plate 13 is placed on the stepped surfaces, and the guide groove 6 is provided below the water-permeable isolation layer plate 13 .

[0035] 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 sealed and connected with the bottom surface of the second rubber protective layer 12 using a special adhesive to ensure that the two are seamlessly fitted, effectively preventing moisture from penetrating into the gap between the second rubber strip 5 and the second rubber protective layer 12 and the waterproof membrane 11, further improving the waterproof performance; a permeable isolation layer plate 13 is placed on the step surface, and the permeable isolation layer plate 13 is made of a high-strength, high-permeability polypropylene fiber reinforced composite material, which has a porous structure, allowing water to pass smoothly, and at the same time, its high strength characteristics enable it to effectively separate and support the permeable concrete layer located above. When a small amount of water seeps through the permeable concrete layer, the permeable isolation layer plate 13 can quickly guide the water to the guide groove 6 below, and quickly and efficiently drain the water to the sump through the inclined guide groove 6, avoiding water accumulation inside the track structure.

[0036] In another embodiment, the first rubber strip 3 includes an integrally formed head and tail, the head is semi-cylindrical, both sides of the head are detachably connected to the top surfaces of the first rail plate 1 and the second rail plate 2, and the tail is perpendicular to the head and fills the upper part of the upper seam.

[0037] In the above embodiment, the first rubber strip 3 includes an integrally formed head and tail. The head is designed to be semi-cylindrical, and the two sides of the head are detachably connected to the top surfaces of the first rail plate 1 and the second rail plate 2, which is convenient for later maintenance personnel to perform disassembly operations with the help of simple tools, thereby reducing maintenance costs and time. The tail is perpendicular to the head and fills the upper part of the upper joint. After filling, the tail can effectively adapt to the shape changes of the upper joint, and can still maintain good sealing under the vibration and pressure generated by the train operation, preventing moisture from penetrating into the joint from the upper part of the upper joint.

[0038] In another embodiment, a boss 14 is provided on the top surface of the first track plate 1 and the second track plate 2 on one side close to the joint, a plurality of positioning protrusions 15 are provided at intervals in the middle of the boss 14 in the extended length direction, and a plurality of positioning grooves are provided at intervals on both sides of the bottom surface of the head along the length direction, and the positioning grooves are engaged with the positioning protrusions 15.

[0039] In the above embodiment, a boss 14 is provided on the top surface of the first track plate 1 and the second track plate 2 near the joint. The boss 14 is made of the same high-strength prestressed concrete material as the track plate, and is integrally formed during the casting process of the track plate, ensuring its close integration with the track plate and structural stability. The height of the boss 14 is preferably 20 mm, and the width is preferably 30 mm. Such a size can effectively block the accumulation of water on the top surface of the track plate, and will not affect the normal operation of the track and the installation of other components. When water accumulates on the top surface of the track plate, the boss 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 from the gap between the first rubber strip and the joint; a plurality of positioning protrusions 15 are arranged at intervals along the length direction of the middle part of the boss 14, and the positioning protrusions 15 are also made of high-strength prestressed concrete material, and are synchronously formed by precise molds when the boss 14 is cast. The height of each positioning protrusion 15 is preferably 8 mm, and the width is preferably 10 mm. The spacing between adjacent positioning protrusions 15 is preferably 150 mm, so as to ensure that the positioning protrusions 15 have sufficient strength and can achieve accurate positioning and connection with the first rubber strip; a plurality of positioning grooves are arranged at intervals along the length direction on both sides of the bottom surface of the head of the first rubber strip 3, and the size and position of these positioning grooves are precisely matched with the positioning protrusions 15. When installing the first rubber strip 3, it is only necessary to align the positioning grooves on the bottom surface of the head with the positioning protrusions 15 on the boss 14 and press lightly to achieve the matching and snap connection between the two. This clamping method is easy to operate, does not require complicated tools and processes, and greatly improves installation efficiency. At the same time, due to the close fit between the positioning protrusion 15 and the positioning groove, the connection between the first rubber strip 3 and the track plate is stable and reliable, and under the complex external forces such as vibration and impact generated by the operation of the train, it can also ensure that the first rubber strip 3 will not be displaced or fall off. The spacing of multiple positioning protrusions 15 also plays a role in precise positioning, ensuring that the first rubber strip 3 is always in the correct position during installation, avoiding the reduction of waterproof and sealing effects due to installation deviation.

[0040] Furthermore, the waterproof coiled material 11 located at the top of the upper seam extends upward and is folded outward to be connected to the surface of the boss 14 to prevent water from penetrating into the gap between the first rubber protective layer 10 and the upper seam, further improving the waterproof effect of the seam.

[0041] In another embodiment, the crack rate calculation formula of the first rubber strip 3 is as follows: Wherein, 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, mm / h; β is the seepage correction factor, and its value range is 0<β≤1.

[0042] Algorithm steps: 1. Data collection: Obtain the detection value Q and rainfall R of the flow sensor in real time.

[0043] Input parameters: A, β.

[0044] 2. Calculation of crack rate: If Q = 0 and R> 0, then η = 0.

[0045] If Q>0, then: Where β needs to be determined by: Laboratory calibration: simulate different crack rates (η) and rainfall (R) in the laboratory, measure the actual Q value, and determine the β value.

[0046] Dynamic correction: Introduce historical data to train the regression model and automatically correct the β value.

[0047] 3. Threshold determination When η> the preset threshold (such as 10%), a maintenance notification is triggered.

[0049] In the above embodiment, the lower end of the guide groove 6 protrudes from the end surface of the lower joint to ensure that the water guided by the guide groove 6 flows into the water collecting tank 7 without hindrance, avoiding water accumulation due to the blocked water flow path, and further improving the drainage efficiency; the water collecting tank 7 is composed of a coaxially arranged rectangular parallelepiped groove and a four-sided pyramid groove located below it.

Various forces are applied, and the bolts 17 are made of 8.8 grade high-strength bolts 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 trough 7 and the permeable concrete layer 4 will not loosen; the side wall of the rectangular parallelepiped groove is provided with a socket specially plugged with the protruding end of the second rubber strip 5, and 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 trough 7 and the second rubber strip 5, but also further enhances the stability of the water collecting trough 7 in the track structure; the bottom of the quadrangular pyramid groove is provided with Drain pipe 8, drain pipe 8 extends into the bottom of filter plate 18 through rubber sleeve 19 and opening 20 pre-installed on filter plate 18, 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 drain ditch and causing blockage; rubber sleeve 19 is made of highly elastic and wear-resistant natural rubber, which not only plays a good supporting role for drain pipe 8, but also can effectively reduce the vibration of water collection tank 7 under the impact of water flow and train vibration by its own elasticity.
