Description

Technical Field

[0001] The present invention relates to the field of treatment of track bed diseases, and particularly to a sleepless track system. Background Art

[0002] With the continuous development of China's rail transit industry, the design forms of rail transit structures have become more and more diverse, including a rail transit form that uses a sleepless monolithic track bed to set up the track structure.

[0003] Among sleepless monolithic track beds, the widely used product is mainly the steel spring floating slab track bed, which has good vibration reduction and noise reduction effects. As the service life of the sleepless monolithic track bed increases, some problems and deficiencies will inevitably occur in the track bed structure, resulting in the failure of the sleepless monolithic track bed, and then leading to a series of problems, mainly in the form of insufficient clearance under the rail and abnormal fastener conditions.

[0004] The conventional treatment system for sleepless monolithic track beds mainly involves chiseling the corresponding failed sections, then re-arranging steel bars and pouring concrete, or drilling holes in the positions of track bed cavities, grouting and filling to lift, etc., and forming a repaired track system after a long time of shaping. Such methods will correspondingly damage the steel bars of the track bed structure during the treatment process, resulting in damage to the strength of the track bed structure itself and reducing the service life of the track bed; while the pouring of concrete requires a long time for cooling and solidification, seriously prolonging the treatment time of the track system, making it impossible to complete the treatment work of the track system within the skylight point and affecting the overall operation of the track system; and the processes such as drilling holes, grouting and filling to lift in the positions of track bed cavities are relatively complex, and the height of grouting and filling to lift needs to be strictly controlled, greatly increasing the complexity and treatment cycle of the treatment work of the existing track system. Summary of the Invention

[0005] In view of one or more of the above defects or improvement requirements in the prior art, the present invention provides a sleepless track system to solve the problems of cumbersome treatment work and long treatment cycle for the failure treatment of the existing sleepless track system.

[0006] To achieve the above object, the present invention provides a sleepless track system, including at least one disease section for failure treatment with thin sleepers, such that the rail is supported and connected to the thin sleepers within the disease section.

[0007] At least a part of the thin sleeper is embedded in the installation slot opened on the top surface of the direct-buried sleeper plate of the sleepless track bed, and the embedding thickness of the thin sleeper is not greater than the distance between the topmost track bed steel bar in the direct-buried sleeper plate of the sleepless track bed and the top surface of the direct-buried sleeper plate.

[0008] As a further improvement of the present invention, the size specifications of the thin sleepers are determined according to the damage parameters of different damaged sections and / or the specification parameters of the direct-buried pad of the sleeper-free track bed, and there are multiple types to choose from.

[0009] As a further improvement of the present invention, the thin sleeper comprises an embedded portion and a height adjustment portion which are sequentially arranged in the thickness direction;

[0010] The embedded portion is embedded in the installation groove and is used to connect the pillowless ballast bed direct-buried pad; the height adjustment portion protrudes from the top surface of the pillowless ballast bed direct-buried pad and is used to adjust the height of the rail.

[0011] As a further improvement of the present invention, sleeper shoulders are provided in pairs on one side of the thin sleeper away from the embedded portion.

[0012] As a further improvement of the present invention, a plurality of connecting pieces are protrudingly provided at the bottom of the thin sleeper, which are used to match and connect with corresponding ballast steel bars after the thin sleeper is embedded in the installation groove.

[0013] As a further improvement of the present invention, the connecting piece is a sleeper steel bar; one end of the sleeper steel bar is pre-buried in the thin sleeper, and the other end protrudes from the end surface of the thin sleeper.

[0014] As a further improvement of the present invention, the ends of the sleeper reinforcements are provided with bending structures, and at least part of the sleeper reinforcements are hung on the corresponding ballast reinforcements by the bending structures at their ends.

[0015] As a further improvement of the present invention, the thickness of the height adjustment part is 5mm~55mm, and the thickness grades of the height adjustment part are divided into six grades of 5mm, 15mm, 25mm, 35mm, 45mm and 55mm for selection.

[0016] As a further improvement of the present invention, the thin sleeper is formed by reinforced concrete, and the thickness of the embedded part is 40mm~60mm.

[0017] As a further improvement of the present invention, the thin sleeper is made of composite material, and the thickness of the embedded part is 20 mm to 40 mm.

[0018] The above-mentioned improved technical features can be combined with each other as long as they do not conflict with each other.

[0019] In general, the above technical solution conceived by the present invention has the following beneficial effects compared with the prior art:

[0020] (1)The sleeperless track system of the present invention sets a thin sleeper structure at the failure point, utilizes the corresponding settings of the embedding part and the height adjustment part in the thin sleeper, and optimizes the dimensions of each part according to the failure condition of the rail structure and the corresponding settlement condition, etc., to achieve the failure rectification of the sleeperless track system, avoiding the replacement of the entire base plate structure and the damage to the ballast bed steel bars in the directly buried base plate during failure rectification, and ensuring the reliability and stability of the sleeperless track system after failure rectification.

[0021] (2)The sleeperless track system of the present invention enables stable connection between the sleeper body and the directly buried base plate during the failure rectification of the directly buried base plate of the sleeperless ballast bed through the corresponding settings of the sleeper steel bars on the sleeper body and the ballast bed steel bars on the directly buried base plate, ensuring the reliability and stability after the thin sleeper is set, avoiding the skew of the embedded sleeves, and improving the setting accuracy of the thin sleeper;

[0022] (3)The sleeperless track system of the present invention optimizes the dimensions and materials of the thin sleeper, enabling the thin sleeper to be applied in different environments after being set, and enabling the thin sleeper to quickly match and rectify the damaged section, saving installation time and effectively reducing the failure rectification cost of the sleeperless track system;

[0023] (4)The sleeperless track system of the present invention has a simple structure and is easy to set. Compared with the existing rectification methods for the directly buried base plate of the sleeperless ballast bed, it can significantly shorten the failure rectification cycle of the directly buried base plate of the sleeperless ballast bed, reduce the construction cost, and has good application prospects and promotion value on the premise of ensuring the structural strength, setting accuracy, and use reliability of the track structure after rectification.

[0037] Embodiment:

[0038] Please refer to Figures 1 to 4 , the sleeperless track system in the preferred embodiment of the present invention includes at least one damaged section rectified with a thin sleeper 1, such that the rail 3 is supported and connected to the thin sleeper 1 within this damaged section, and at least a part of the thin sleeper 1 is embedded in the installation slot opened on the top surface of the direct-buried sleeperless track slab 2, and the embedding thickness of the thin sleeper 1 is not greater than the distance between the topmost layer of ballast bed steel bars 202 in the direct-buried sleeperless track slab 2 and the top surface of the direct-buried sleeperless track slab 2.

[0039] By using the thin sleeper 1 embedded in the installation slot on the top surface of the direct-buried sleeperless track slab 2 and limiting the size and thickness of the thin sleeper 1, damage to the ballast bed steel bars 202 in the direct-buried sleeperless track slab 2 caused during the installation and use of the thin sleeper 1 can be avoided, such that while the thin sleeper 1 supports and connects the rail 3, the structure of the ballast bed steel bars 202 of the direct-buried sleeperless track slab 2 is protected to the greatest extent, and damage to the structure of the direct-buried sleeperless track slab 2 during the rectification process is avoided.

[0040] Specifically, the thin sleeper 1 includes a buried part and a height-adjusting part arranged in sequence in the thickness direction; wherein the buried part is embedded in the installation slot for connecting the direct-buried sleeperless track slab 2; the height-adjusting part protrudes from the top surface of the direct-buried sleeperless track slab 2 for adjusting the height of the rail 3. In actual practice, height-adjusting parts and / or buried parts of different thicknesses can be selected, thereby obtaining thin sleepers 1 of different specifications and dimensions to correspond to the height-adjusting amounts at different failure positions.

[0041] Specifically, the size specifications of the thin sleeper 1 can be determined according to the measurement of the corresponding failed line, the height-adjusting amount at its failure position, and the height-adjusting grade of the corresponding thin sleeper 1.

[0042] Among them, the main measured parameter indicators in the measurement of the failed line include but are not limited to the track surface height, the clearance under the rail, the settlement of the fastener 4 and the directly buried pad 2 of the sleeperless ballast bed, the disease type and the location information, etc.; then, according to the precise measurement data on-site, the elevation curves of each point on the line are statistically analyzed, combined with the line design parameters, the differences between the on-site detection data and the design parameters are analyzed, and a failure rectification parameter statistical table for each point is compiled, and its optimization includes a lift amount statistical table and a sleeper bearing surface elevation statistical table; the determination of the lift grade of the thin sleeper 1 is mainly determined by the lift amount statistical table to determine the lift amount at different positions of the directly buried pad 2 of the sleeperless ballast bed, and different lift grades of the thin sleeper 1 are selected according to the determined lift amount and the design index of the directly buried pad 2 of the sleeperless ballast bed.

[0043] As Figure 3 As shown in , during the actual setting process, the embedding part and the lift part are uniformly divided in the sleeper body 101, and the thickness of the sleeper body 101 is equal to the thickness d1 of the embedding part plus the thickness d2 of the lift part. During actual setting, the thickness d1 of the embedding part is preferably between 20 mm and 60 mm.

[0044] More specifically, usually, the thickness of the embedding part is between 40 and 60 mm. At this time, the distance from the ballast bed steel bar 202 at the topmost layer in the thickness direction of the directly buried pad 2 of the sleeperless ballast bed to the top surface of the ballast bed slab 201 is not less than the thickness of the embedding part, that is, the thickness of the embedding part is not greater than the minimum distance between the top surface of the directly buried pad 2 of the sleeperless ballast bed and the ballast bed steel bar 202, so as to ensure that the embedding of the embedding part will not damage the ballast bed steel bar 202, thereby ensuring the structural stress stability of the directly buried pad 2 of the sleeperless ballast bed after the thin sleeper 1 is set, and having little impact on the bearing capacity and overall performance of the directly buried pad 2 of the sleeperless ballast bed.

[0045] In special cases, the distance from the ballast bed steel bar 202 at the topmost layer in the thickness direction of the directly buried pad 2 of the sleeperless ballast bed to the top surface of the ballast bed slab 201 is small. At this time, in order to avoid damage to the ballast bed steel bar 202 after the thin sleeper 1 is set, the set thickness of the embedding part is preferably 20 mm - 40 mm; however, since the embedding depth of the embedding part is low at this time, in order to ensure that the bonding force between the thin sleeper 1 and the directly buried pad 2 of the sleeperless ballast bed meets the setting requirements, the preparation material of the thin sleeper 1 is changed from ordinary reinforced concrete to high-strength composite material to increase the strength of the thin sleeper 1 itself and avoid the problem of small bonding force between the thin sleeper 1 and the directly buried pad 2 of the sleeperless ballast bed. Here, the high-strength composite material is mainly based on reinforced concrete and is structurally enhanced by adding steel wires, fiber materials, etc.

[0046] In a preferred embodiment, the thickness d2 of the height adjustment portion of the thin sleeper 1 is 5mm-55mm, and according to the comprehensive setting of the height adjustment portion and the buried portion, the thickness of the load-bearing part of the thin sleeper 1 (i.e., the sleeper body 101) is between 50mm-110mm. However, according to the needs of actual construction, the thickness of the height adjustment portion may also correspond to a value beyond the above range. For example, in the case of treatment of certain extreme diseases, the thickness of the height adjustment portion may even reach or exceed 150mm, which can be optimized according to actual conditions. During actual preparation, it is preferred to set up thin sleepers 1 of various sizes as options, and the thickness of the sleeper body 101 of different thin sleepers 1 is different. At the same time, in the preferred embodiment, it can be divided into ordinary type and special type according to the thickness of the buried portion, as shown in the above content.

[0047] Secondly, in the preferred embodiment, according to the different thicknesses of the height adjustment part, thin sleepers 1 with different adjustment levels are preferably divided into 6 levels, namely 5mm level, 15mm level, 25mm level, and so on, until 55mm level. When the height adjustment amount is 0-10m, a 5mm level thin sleeper 1 is selected, and when the height adjustment amount is 10mm-20mm, a 15mm level thin sleeper 1 is selected, and so on.

[0048] In actual use, the thin rail sleeper 1 can be produced or prepared accordingly after the height adjustment statistics table is determined, that is, the height adjustment amount of the corresponding position is determined according to the height adjustment statistics table, and then the height adjustment amount is divided into intervals of 10 mm, and finally the thin rail sleeper 1 is designed and produced on this basis. In this way, the mass production of thin rail sleepers 1 can be avoided, the accumulation of thin rail sleepers 1 can be reduced, costs can be saved, and waste can be reduced.

[0049] Preferably, in order to improve the bearing stability of the thin sleeper 1 on the rail 3, a sleeper shoulder 102 structure is further provided on the side of the thin sleeper 1 away from the buried portion. The sleeper shoulder 102 structure can be arranged in pairs or on one side to prevent the rail 3 from shifting in the lateral direction.

[0050] In addition, the width b1 and the angle θ of the rail shoulder 102 can be designed based on the curve radius of the line, the train speed, the axle weight and other factors. For lines with small curve radius, fast speed and large axle weight, a larger width and angle of the rail shoulder can be set, and vice versa, so it will not be described here. Moreover, according to different lines and types of fasteners 4, the thin rail sleeper 1 may not be provided with the rail shoulder 102.

[0051] Furthermore, if Figure 3 , Figure 4As shown in the figure, in the preferred embodiment, a plurality of connectors are protruding from the bottom of the thin sleeper 1, which are used to match and connect the corresponding ballast steel bars 202 after the thin sleeper 1 is embedded in the installation slot. In the process of setting the thin sleeper 1, in order to ensure the bonding force and tensile strength between the thin sleeper 1 and the direct-buried pad 2 of the non-sleeper ballast, a connector is provided at the bottom of the thin sleeper 1, and the connector is connected to the ballast steel bars 202 on the direct-buried pad 2 of the non-sleeper ballast, or the tensile strength between the connector and the poured concrete is increased to ensure the reliability and stability of the thin sleeper 1 at the installation slot.

[0052] Preferably, the connecting member preferably adopts a sleeper steel bar 103, and the end of the sleeper steel bar 103 away from the sleeper body 101 is set to a bent structure, so that when the thin sleeper 1 is set on the sleeper-free ballast bed direct buried pad 2, the sleeper steel bar 103 can be vertically hung on the ballast bed steel bar 202, such as Figure 4 At the same time, in a preferred embodiment, the sleeper reinforcement 103 with the ends in a bent form includes two types located in the transverse vertical plane and the longitudinal vertical plane of the sleeper body 101, which are used to be hung on the ballast reinforcement 202 arranged in the transverse direction and in the longitudinal direction, respectively. In addition, in order to further improve the installation reliability of the thin sleeper 1, the sleeper reinforcement 103 is connected to the ballast reinforcement 202, and the connection method of the two includes but is not limited to reinforcement binding and welding.

[0053] Furthermore, if Figure 2 As shown in , the sleeper body 101 in the preferred embodiment is also pre-embedded with an embedded sleeve 104, which penetrates the sleeper body 101 along the thickness direction of the sleeper body 101, with one end protruding from the end surface of the embedded part and the other end not protruding from the end surface of the height adjustment part. At the same time, the embedded sleeve 104 and the sleeper steel bar 103 are respectively integrally formed when the thin sleeper 1 is formed, and are used for connecting the fastener 4 when the thin sleeper 1 is set.

[0054] When the pillowless ballast bed direct buried pad 2 partially settles during use, for example Figure 1 In the area surrounded by the middle dotted line, at this time, the fastener 4 can be removed from the sleeperless ballast direct-buried pad 2, and a corresponding installation slot can be opened at the location where the fastener 4 is set, and then the corresponding thin sleeper 1 can be embedded in the installation slot, and the sleeper steel bars 103 of the thin sleeper 1 can be connected to the ballast bed steel bars 202, and then the thin sleeper 1 can be embedded in the installation slot, and the sleeper steel bars 103 of the thin sleeper 1 can be connected to the ballast bed steel bars 202, and then the thin sleeper 1 and the sleeperless ballast direct-buried pad 2 can be cast as one; after the casting and forming, the rail 3 can be restored, thereby completing the partial failure remediation of the sleeperless ballast direct-buried pad 2.

[0055] Preferably, during the actual installation process, to facilitate the placement of the thin-type sleeper 1 and the connection between the sleeper steel bars 103 and the ballast bed steel bars 202, the actual size of the installation notch should be slightly larger than that of the thin-type sleeper 1, so that a margin of approximately 20 mm - 30 mm is reserved on each side of the corresponding thin-type sleeper 1. At the same time, to reduce the impact of the groove excavation on the nearby ballast bed and fasteners 4, in the preferred embodiment, it is preferably to use a small cutting machine to cut the side line, then use a pneumatic pick to chisel the concrete, and use a electric hammer to cooperate in the construction, and finally form an installation notch for embedding the thin-type sleeper 1.

[0056] Further, after the selection of the above-mentioned thin-type sleeper 1 is determined, it also includes steps and processes such as the cleaning of the installation notch, the installation of the thin-type sleeper 1, the erection of the formwork, the sprinkler curing, the inspection and review, etc. Specifically as follows:

[0057] (1) Clean the sundries in the installation notch. According to the sleeper elevation of the thin-type sleeper 1, determine its installation position with the help of the tooling and mark it, and then place the corresponding thin-type sleeper 1 in place with reference to the marked position. During the setting process, it should be noted to ensure that the position of the sleeper embedded sleeve 104 is consistent with the position of the original fastener 4.

[0058] (2) Bind and connect the sleeper steel bars 103 and the ballast bed steel bars 202, and further preferably carry out spot welding at the local part for strengthening. In addition, when the end of the sleeper steel bar 103 is set in a bent form, hang the end of the sleeper steel bar 103 on the corresponding ballast bed steel bar 202.

[0059] (3) Erect the formwork, and apply a special interface agent on the inner peripheral wall surface of the groove, and carry out the pouring operation between the thin-type sleeper 1 and the direct-buried plate 2 of the sleeperless ballast bed. In the preferred embodiment, the pouring operation uses a special high-strength early-strength polymer mortar concrete to ensure that the concrete can be initially set to a certain strength within the skylight point. During pouring, use a small vibrating rod to vibrate it densely, and carry out the plastering operation in time.

[0060] (4) Sprinkler cure. After the concrete strength meets the requirements, remove the formwork; thereafter, measure the bearing surface elevation of the thin-type sleeper 1 and review it with the design value. After being correct, install the fastening fasteners 4.

[0061] (5) After completing the above process, review the rectification parameters of the line to judge whether the line after the failure rectification meets the specification requirements in terms of track geometric parameters such as gauge, alignment, elevation, and cross level; if it meets, the failure rectification work is completed; if it does not meet, corresponding rectification operations need to be carried out until it meets the specification requirements.

[0062] The sleepless track system in the present invention has a simple structure and is easy to set up. Compared with the existing failure rectification solutions for sleepless track systems, it can significantly shorten the failure rectification period of the directly buried soleplate 2 of the sleepless roadbed, reduce the construction cost, and has good application prospects and promotion value on the premise of ensuring the structural strength, setting accuracy, and use reliability of the track structure after rectification.

[0063] It is easy for those skilled in the art to understand that the above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention should be included within the protection scope of the present invention.
