Description

Technical Field

[0001] The invention relates to the technical field of rail transportation, and in particular to a quick-assembled track based on a rectangular structure. Background Art

[0002] In order to implement the concept of high-quality development of urban rail transit, the track structure has gradually changed from traditional cast-in-place technology to prefabricated construction in recent years. At present, most of the prefabricated track structures of urban rail transit have borrowed from the ballastless track system of high-speed railways. However, the construction environment of urban rail transit is different from that of high-speed railways, with characteristics such as a high proportion of tunnels, abundant groundwater, and small working space.

[0003] In the existing structure, a series of auxiliary machines and tools such as auxiliary support machines and plate pressing machines are required during the track slab laying process. Due to the small space in the tunnel, the auxiliary machines are very difficult to operate and have a high loss rate, which does not conform to the green and economic development concept. In addition, the existing technical solutions generally use on-site casting to fill the space between the track slab and the ground foundation. Although the filling layer can play a certain supporting and limiting role, the quality of the filling layer is difficult to guarantee because it is cast on-site. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides a quick-assembly track based on a rectangular structure.

[0005] The present invention provides a quick assembly track based on a rectangular structure, comprising: The track plate comprises at least one pair of tongue and groove, wherein the tongue and groove are arranged on both sides of the extending direction of the track plate and face the ground foundation; A support column is arranged between the track plate and the ground foundation, and the support column is wedged and fixed in the mortise and tenon groove; The position of the track plate and the distance between the track plate and the ground foundation vary with the distance between the support column and the edges on both sides of the track plate in the extending direction.

[0006] Optionally, the distance between the track plate and the ground foundation decreases as the distance between the support column and the edges on both sides of the track plate in the extension direction decreases.

[0007] Optionally, the depth of the tongue and groove increases as the distance from the two side edges in the extension direction of the track plate decreases, and the length of the support column increases as the distance from the two side edges in the extension direction of the track plate decreases.

[0008] Optionally, a side of the tenon groove facing the supporting column is a first plane, and a side of the supporting column facing the tenon groove is a first curved surface protruding toward the tenon groove; Along the extension direction perpendicular to the track, the curvature of the first curved surface at any different positions is different.

[0009] Optionally, one side of the mortise groove facing the supporting column is a second curved surface protruding toward the supporting column, and one side of the supporting column facing the mortise groove is a third curved surface recessed toward the mortise groove; The second curved surface has the same curvature as the third curved surface.

[0010] Optionally, a surface of the support column facing the ground foundation is a fourth curved surface protruding toward the ground foundation; Along the extension direction perpendicular to the track plate, the curvatures of the fourth curved surface at any different positions are different.

[0011] Optionally, the angle between the first contact surface and the horizontal direction is smaller than the maximum static friction angle; Wherein, the first contact surface is the contact surface between the tongue and tongue and the supporting column.

[0012] Optionally, a filling layer is also included; The filling layer is filled between the track slab and the ground foundation.

[0013] Optionally, at least one filling injection hole is provided on the surface of the track plate; The filling layer is injected between the track plate and the ground foundation through the filling injection hole.

[0014] Optionally, the opening size of the filling injection hole gradually decreases in a direction away from the ground foundation.

[0015] The embodiments of the present invention have the following technical effects: The quick-assembly track based on a rectangular structure provided by the present invention can adjust the distance between the track plate and the ground foundation through the support columns during the process of assembling the track plate, that is, it actually adjusts the position of the track plate relative to the ground. After the position adjustment of the track plate is completed and the support columns are fixed into the mortise and tenon, the position of the track plate is also fixed. In the process of forming the track structure, it is no longer necessary to maintain the position of the track plate through specific auxiliary equipment, and the installation is easier. The support columns can play a permanent supporting and limiting role on the track plate. Since the support columns are not cast on site, but can be made in a prefabricated manner, the quality can be better guaranteed, and the supporting and limiting effects on the track plate are better.

DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0020] Figure 1 A schematic diagram of a quick assembly track structure based on a rectangular structure provided by the present invention includes: The track plate 100 includes at least one pair of tongue and groove 101 , and the tongue and groove 101 are arranged on both sides of the extending direction of the track plate 100 and face the ground foundation.

[0021] The support column 200 is disposed between the track plate 100 and the ground foundation, and the support column 200 is wedged into and fixed in the tongue groove 101 .

[0022] The position of the track plate 100 and the distance between the track plate 100 and the ground foundation vary with the distance between the support column 200 and the edges on both sides of the track plate 100 in the extending direction.

[0023] like Figure 1 As shown, Figure 1 (a) is the assembly diagram, Figure 1 (b) is an exploded view. The fast assembly track in the present invention refers to a track structure that can be assembled and is at least partially based on a prefabricated structure. The track structure can be used to provide tracks for rail vehicles such as subways.

[0024] The track plate 100 is a component located on the ground surface for fixing the rails. The support column 200 is a component for supporting the track plate 100 and adjusting the position of the track plate 100 relative to the ground foundation. The ground foundation can be simply understood as the ground.

[0025] In the section where the track structure extends from the track start point to the track end point, the track structure may need to form different postures due to changes in the natural environment or the route of the track structure. For example, at certain curve positions, the track structure near the inner side of the curve has a lower level, while the track structure near the outer side of the curve has a higher level, so as to ensure that the rail vehicle will not run off the track due to centrifugal force during the curve.

[0026] Correspondingly, the track structure in the embodiment of the present invention is composed of multiple track plates 100, so it is also necessary to set the track plates 100 to different postures based on actual conditions. In order to solve this technical problem more easily and reduce the use of auxiliary machinery and tools, the embodiment of the present invention additionally sets a support column 200, and sets a tongue and groove 101 on the side of the track plate 100 facing the ground foundation.

[0027] For the convenience of description, the embodiments of the present invention are described in Figure 1 Three lines L1, L2 and L3 are schematically shown, wherein L1 and L2 are edges on both sides of the extension direction of the track plate 100, L1 is the first side, L2 is the second side, and the distance between L3 and L1 is the same as the distance between L3 and L2, that is, L3 is the center line of the extension direction of the track plate 100.

[0028] Figure 1 Due to the perspective, the two support columns 200 shown are both shown on the L2 side, but it can be understood that two support columns 200 are also provided on the L1 side. In the process of assembling the track plate 100, the position of the track plate 100 can be adjusted first, and then the support column 200 can be wedged into the mortise 101; or the support column 200 can be directly wedged into the mortise 101, and then the distance between the support column 200 and L3 can be adjusted, and then the distance between the track plate 100 and the ground foundation can be adjusted, thereby achieving the adjustment and / or fixing of the position of the track plate 100 by the support column 200. For example, if the distance between the L2 side of the track plate 100 and the ground foundation needs to be adjusted, the distance between the two support columns 200 on the L2 side and L3 can be adjusted. After the position of the track plate 100 is fixed, subsequent construction steps can be performed, such as building the track plate 100.

[0029] During the subsequent construction steps, since the support column 200 fixes the position of the track plate 100 throughout the entire process, there is no need to fix the track plate 100 through other auxiliary equipment, thereby reducing the use of auxiliary equipment. It is also understandable that a single track plate 100 is relatively light and can be moved manually, so even in a relatively narrow space, normal construction can still be carried out, and the construction will not be affected by the small space and the inability to use auxiliary equipment. Moreover, during the operation of the track structure, the support column 200 can still play a supporting and limiting role, realizing a permanent and temporary combination.

[0030] In the prior art solutions, only the filling layer cast on site is used to support and limit the track slab. The quality of the filling layer cast on site is difficult to guarantee. For example, the structural strength of the filling layer is insufficient due to inaccurate positioning of the steel bars used to improve the structural strength. Another example is that due to the influence of insect pests, temperature, etc., hollowing, cracking, etc. are eventually produced, and the supporting and limiting effects of the track slab are deteriorated. The support column is a prefabricated component that can be manufactured in the manufacturing site and then transported to the site. Compared with on-site manufacturing, the quality of the prefabricated support column can be better guaranteed. Therefore, compared with the solution in the prior art solution that supports and limits the track slab by a cast filling layer, the support and limiting effects of this solution are better.

[0031] In some embodiments, the distance between the track plate and the ground foundation decreases as the distance between the support column and the edges on both sides of the track plate in the extension direction decreases.

[0032] Continue reading Figure 1In the process of assembling the track plate 100 and adjusting the distance between the track plate 100 and the ground foundation through the support column 200, it is necessary to move the position of the support column 200 in a direction perpendicular to the extension direction of the track plate 100. In the case where the distance between the track plate 100 and the ground foundation decreases with the decrease of the distance between the support column 200 and L1 or L2 of the track plate 100 (i.e., the smaller the distance between the support column 200 located on the L1 side and L1, the smaller the distance between the L1 side of the track plate 100 and the ground foundation, the smaller the distance between the support column 200 located on the L2 side and L2, the smaller the distance between the L2 side of the track plate 100 and the ground foundation, or it can be understood that the larger the distance between the support column 200 and L3, the smaller the distance between the track plate 100 on the side where the support column 200 is located and the ground foundation), the support column 200 can be wedged from the outside of the track plate 100. If it is necessary to increase the distance between the track plate 100 and the ground foundation, force can be applied to the support column 200 from the outside, which is relatively easy. On the contrary, the distance between the track plate 100 and the ground foundation increases as the distance between the support column 200 and L1 or L2 of the track plate 100 decreases. If the distance between the track plate 100 and the ground foundation needs to be increased, the support column 200 needs to be moved outward, and force needs to be applied to the support column 200 from the inside. The space is relatively narrow, which is not conducive to construction.

[0033] Figure 2 A schematic diagram of a track plate and a support column structure provided by an embodiment of the present invention. In some embodiments, the depth of the mortise 101 increases as the distance between the mortise 101 and the edges on both sides of the track plate 100 decreases, and the length of the support column 200 increases as the distance between the mortise 101 and the edges on both sides of the track plate 100 decreases.

[0034] Specifically, it can be done by Figure 2 The distance between the track plate 100 and the ground foundation is reduced as the distance between the support column 200 and L1 or L2 of the track plate 100 decreases. The side of the tenon groove 101 facing the support column 200 may be a first surface, and the side of the support column 200 facing the tenon groove 101 may be a second surface. The second surface may be described as a wedge-shaped section. The shapes of the first surface and the second surface match each other. The size of the support column 200 is slightly smaller than the opening size of the tenon groove 101, so that the support column 200 can be smoothly wedged into the tenon groove 101.

[0035] Figure 3 A schematic diagram of a track plate structure provided in an embodiment of the present invention. Figure 4 A schematic diagram of a supporting column structure provided by an embodiment of the present invention. In some embodiments, the side of the tenon groove 101 facing the supporting column 200 is a first plane, and the side of the supporting column 200 facing the tenon groove 101 is a first curved surface protruding toward the tenon groove 101 .

[0036] Along the extension direction perpendicular to the track, the curvatures of the first curved surface at any different positions are different.

[0037] Specifically, in different environments, the support column 200 is required to raise the track plate 100 to different heights. Moreover, not all environments can form a relatively perfect situation in which the first surface S1 and the second surface S2 can be completely attached.

[0038] To this end, the embodiment of the present invention sets the first surface S1 of the mortise 101 as a first plane, and sets the second surface S2 of the support column 200 as a first curved surface. In addition, the third surface of the support column 200 facing the ground foundation can also be set as a second plane.

[0039] In the embodiment of the present invention, the ground foundation is assumed to be a plane. It should be noted that the descriptions such as "first curved surface" and "second curved surface" in the embodiment of the present invention refer to the edges of the cross section perpendicular to the extension direction of the track plate 100 being curved, while the edges of the cross section parallel to the extension direction of the track plate 100 are not limited. Figure 4 Taking the supporting column 200 in FIG. as an example, Figure 4 , four sides of the second surface S2 are shown, namely, the first side L11, the second side L12, the third side L13 and the fourth side L14. The first side L11 and the third side L13 are parallel to the extension direction of the track plate 100, and the second side L12 and the fourth side L14 are perpendicular to the extension direction of the track plate 100. The second side L12 and the fourth side L14 are curves, and the first side L11 and the third side L13 can be straight lines or curves.

[0040] Figure 5 A schematic diagram of another track plate and support column structure provided by an embodiment of the present invention. Figure 5 (a) corresponds to a straight line segment, Figure 5 (b) Corresponding to the ground foundation intrusion limit section, Figure 5(c) Corresponding to curved sections. When the track plate 100 corresponds to a straight section or a ground foundation limit section, the angle between the first surface S1 and the horizontal direction is fixed and can be 16°. The middle part of the second surface S2 of the support column 200 can be a curved surface with an angle between the section and the horizontal direction. By adjusting the distance between the support column 200 and the side edge of the track plate 100 in the extension direction, the support column 200 and the tongue groove 101 can fit tightly. When the track plate 100 corresponds to a curved section, the track plate 100 rotates around the center to achieve superelevation. The superelevation value can be between 0-120mm. The angle between the first surface S1 of the tongue groove 101 and the horizontal direction can be 11.4°-20.6°. The angle between one of the sections of the second surface S2 and the horizontal direction can also be 11.4°-20.6°. By adjusting the distance between the support column 200 and the side edge of the track plate 100 in the extension direction, the support column 200 and the tongue groove 101 can fit tightly. Since the curvatures of the first curved surface at different positions are different, a portion of the first surface S1 and the second surface S2 can be closely fitted at any position.

[0041] Figure 6 A schematic diagram of another track plate structure provided in an embodiment of the present invention. Figure 7 Another structural schematic diagram of a support column provided by an embodiment of the present invention. In some embodiments, the side of the mortise 101 facing the support column 200 is a second curved surface protruding toward the support column 200 , and the side of the support column 200 facing the mortise 101 is a third curved surface recessed toward the mortise 101 .

[0042] The second curved surface has the same curvature as the third curved surface.

[0043] In another embodiment, the first surface S1 can be set as a second curved surface convex outward, and correspondingly, the second surface S2 is a third curved surface concave inward. Since the curvature of the second curved surface and the third curved surface are the same, the second curved surface can fit closely with the third curved surface, and the support column 200 can tightly fix the track plate 100. It should be noted that due to Figure 6 Due to the perspective, the mortise and tenon groove 101 and the first surface S1 are indicated at the same position, but it can be understood that the first surface S1 is only one surface of the mortise and tenon groove 101 .

[0044] Continue reading Figure 6 In some embodiments, the side of the support column 200 facing the ground foundation is a fourth curved surface protruding toward the ground foundation.

[0045] Along the extending direction perpendicular to the track plate 100 , the curvatures of the fourth curved surface at any different positions are different.

[0046] On the basis that the second curved surface and the third curved surface are closely fitted to realize that the support column 200 can support the track plate 100, it is also necessary to consider how the support column 200 can stably fit with the ground foundation. To this end, the embodiment of the present invention sets the third surface S3 as the fourth curved surface, which is similar to the above Figure 4 Similar to the embodiment in, since the third surface S3 is a curved surface and the curvatures of the fourth curved surfaces at different positions are different, at least a portion of the third surface S3 can be tightly fitted to the ground foundation and fixed on the ground.

[0047] Figure 8 A schematic diagram of another track plate and support column structure provided by an embodiment of the present invention. Figure 8 (a) corresponds to a straight line segment, Figure 8 (b) Corresponding to the ground foundation intrusion limit section, Figure 8 (c) Corresponding to a curved section. When the track plate 100 corresponds to a straight section or a curved section, at any rotation angle of the track plate 100, the first surface S1 of the tenon 101 is located on the same circle with the same center and radius, the angle between the contact surface between the tenon 101 and the support column 200 and the horizontal direction is fixed at 19°, and the angle between the third surface S3 of the support column 200 and the section of the second surface S2 is also 19°. By adjusting the distance between the support column 200 and the side of the track plate 100 in the extension direction, a close fit can be achieved. When the track plate 100 corresponds to the limited section of the ground foundation, the construction error can be between 0-70mm, the angle between the contact surface between the mortise and tenon 101 and the supporting column 200 and the horizontal direction is 19°-23°, and the angle between the third surface S3 of the supporting column 200 and the tangent surface of the second surface S2 is also 19°-23°. Since the curvatures of the fourth curved surfaces at different positions are different, a tight fit can be achieved between a part of the ground foundation and any position of the third surface S3.

[0048] In some embodiments, the angle between the first contact surface and the horizontal direction is less than the maximum static friction angle.

[0049] The first contact surface is the contact surface between the mortise and tenon and the supporting column.

[0050] Specifically, the maximum static friction angle indicates the angle corresponding to the maximum static friction force between the track plate and the support column. In the process of the track plate applying force to the support column, since the contact surface between the track plate and the support column is at an angle with the horizontal direction, the track plate will also apply horizontal force to the support column. If the horizontal force is too large, the track plate will push the support column away. Whether the support column can be pushed away depends on whether the horizontal force applied by the track plate to the support column is greater than the maximum static friction force. The maximum static friction force is related to the angle between the first contact surface and the horizontal direction. The more the angle is inclined to a right angle, the smaller the maximum static friction force.

[0051] The embodiment of the present invention can estimate the force applied by the track plate to the support column in advance by relevant methods, and then determine the maximum static friction angle, and finally make the angle between the first contact surface and the horizontal direction smaller than the maximum static friction angle, thereby ensuring that the support column will not slide relative to the track plate.

[0052] Continue reading Figure 1 , in some embodiments, a filling layer 300 is also included.

[0053] The filling layer 300 is filled between the track slab 100 and the ground foundation.

[0054] Specifically, after the support column 200 supports the track plate 100 , a cavity is formed between the track plate 100 and the ground foundation, and the cavity can be filled with the filling layer 300 to achieve the overall support function for the track plate 100 .

[0055] The filling layer 300 may be made of concrete, and may be injected between the track plate 100 and the ground foundation.

[0056] Continue reading Figure 1 In some embodiments, at least one filling injection hole 102 is disposed on the surface of the track plate 100 .

[0057] The filling layer 300 is injected between the track slab 100 and the ground foundation through the filling injection hole 102 .

[0058] Since the filling layer 300 needs to be filled after the track plate 100 is laid, and after the track plate 100 is laid, it is difficult to inject the filling layer 300 from both sides, so the embodiment of the present invention sets at least one filling injection hole 102 on the surface of the track plate 100, and the filling layer 300 can be injected from the filling injection hole 102 into the space between the track plate 100 and the ground foundation. Under this scheme, the filling layer 300 is preferably injected from the filling injection hole 102 with high fluidity grouting material, so as to reduce the possibility of a gap between the track plate 100 and the ground foundation. After a large number of construction deviation cases, the present invention adopts 95% applicability, and the distance between the track plate 100 and the ground foundation is 160mm, which can adapt to the civil engineering error of 0-70mm, increasing the adaptability of the present invention.

[0059] In some embodiments, the opening size of the fill injection hole gradually decreases in a direction away from the ground foundation.

[0060] In some scenarios, after the track structure is laid, there may be internal settlement problems, and the track plate needs to be removed for maintenance. To this end, the embodiment of the present invention makes the opening size of the filling injection hole gradually decrease in the direction away from the ground foundation. During the disassembly process, it is only necessary to extend the lifting device into the filling injection hole. Based on the characteristics of the filling injection hole being narrow at the top and wide at the bottom, the track plate can be lifted.

[0061] In some embodiments, an isolation layer is provided on the surface of the track plate, and the isolation layer has a low bonding degree, so that the track plate can be separated from the filling layer and the supporting column relatively easily.

[0062] In some embodiments, the track plate further comprises bolt sleeves 103 disposed on one side of the track plate away from the ground foundation and on both sides of the track plate in the horizontal direction. The bolt sleeves 103 are used to lift the track plate.

[0063] Based on the narrow underground working space of urban rail transit, the specifications and dimensions of the bolt sleeve 103 can be customized according to the form and dimensions of a small portable gantry crane.
