Description
Technical Field
The application relates to the field of track engineering, in particular to a vibration reduction track assembly, a vibration reduction track structure and construction and maintenance methods thereof.
Background
Depending on the application of the track, different damping structures are often required.
For railway tracks, it is usual to apply an elastic damping pad layer on a track substrate, and to arrange a track plate on the elastic damping pad layer and to fix the track plate to the track substrate by means of a poured filling layer. When the vibration reduction materials, the tunnel structure and the like need to be replaced and maintained, the track plate is moved out, then the vibration reduction cushion layer is replaced and maintained, a filling layer is required to be poured after the track plate is repositioned, which is equivalent to the fact that one-time reconstruction is carried out, and the maintenance flow is complex. And moreover, the pouring filling layer can be recovered to be used only by reaching a certain strength, so that the construction efficiency is reduced, and the outage and operation risks are increased.
For the regulations used in subway systems, the tunnel cross section is significantly smaller than the railway regulations, and the vibration reduction structure of the railway track cannot be used. In the prior art, the damping pad is usually fixed at the bottom of the track slab, and then self-compacting concrete is filled between the track slab and the tunnel so as to reduce the track height and adapt to smaller tunnel sections. When the vibration damping pad needs to be replaced or other maintenance is carried out, as the three sides of the track slab are surrounded by the self-compacting concrete, the track slab can be dismantled only by locally breaking the self-compacting concrete, after the maintenance, the space between the track slab and the self-compacting concrete which is broken is filled and poured, and the pouring structure has the problems of insufficient strength, higher fragmentation risk and poor durability due to thinner thickness.

Detailed Description
The technical scheme of the present application will be described in detail below with reference to the accompanying drawings in combination with embodiments.
According to one aspect of the present application, there is provided a vibration damping rail assembly, wherein the vibration damping rail assembly comprises a rail plate 10, an insulation case 20, and a vibration damping member 30, the rail plate 10 being releasably positioned within the insulation case 20, the vibration damping member 30 being interposed between the rail plate 10 and the insulation case 20.
According to another aspect of the present application, there is provided a vibration reducing track structure, wherein the vibration reducing track structure comprises a tunnel foundation 50 and the vibration reducing track assembly of the present application, and the insulation case 20 is fixed to the tunnel foundation 50 by a casting structure.
In the technical scheme of the application, the isolation shell 20 can be fixed on the tunnel foundation 50 in a pouring manner, and when in maintenance, the track plate 10 is released from the isolation shell 20 without damaging pouring parts, so that the construction and maintenance can be conveniently and efficiently carried out.
The technical scheme of the application can be applied to railway tracks and subway tracks. In particular, the separator housing 20 can function like the filler layer of the prior art railway track vibration damping structure. By providing the insulating shell 20 to substantially match the shape of the track slab 10, the height can be greatly reduced compared to the filling layer so as to be suitable for use in a subway track.
In the prior art, whether a railway track or a city track (including a subway track), the track slab may be damaged when the track slab is removed due to the fact that the track slab directly contacts the casting portion, and the track slab may need to be replaced after maintenance. In the technical scheme of the application, the isolation shell 20 enables the track plate 10 to be completely isolated from a concrete structure (such as a tunnel foundation 50) outside the isolation shell 20, so that the track plate 10 and the vibration reduction piece 30 can be better protected, the service life is prolonged, and conditions are created for nondestructive maintenance. Wherein, since the track plate 10 is releasably positioned, the removal of the track plate 10 does not damage the track plate 10 during maintenance, and can be reused after maintenance, significantly reducing maintenance costs.
In the present application, the vibration damping member 30 may take a suitable form. For example, the vibration damping member 30 may include a vibration damping pad. Since the vibration damping member 30 is located in the separator 20, direct contact of the vibration damping member 30 with the tunnel foundation 50 is avoided, and thus the vibration damping member 30 may be provided in an appropriate laying manner, for example, the vibration damping member 30 may be provided in a full-scale form (the embodiment shown in fig. 3), a stripe-scale form (the embodiment shown in fig. 1 to 2), a dot-scale form (the embodiment shown in fig. 4), or the above-described laying manner may be mixed as needed.
The track plate 10 and the separator housing 20 may be releasably positioned relative to one another in a suitable manner. For example, the track plate 10 and the separator 20 may be detachably fixed by fasteners. In order to simplify the structure and improve the space utilization, it is preferable that the isolation housing 20 has a box-type structure with an opened upper portion, and the track plate 10 may be releasably pressed and positioned with respect to the sidewall of the isolation housing 20 by a stopper 40. Therefore, the limiting device 40 is tightly pressed between the track plate 10 and the isolation shell 20, so that the relative positioning of the track plate 10 and the isolation shell 20 can be ensured, and the stability of the whole vibration reduction track assembly and the vibration reduction track structure can be further ensured. To minimize the space taken up by the vibration damping track assembly, it is more preferable that the isolation housing 20 is wrapped around the track slab 10 with a small gap so that the spacing means 40 can be arranged more compactly and accommodated in the gap. In addition, in order to provide a stable positioning of the track plate 10 and the separator 20, a plurality of stoppers 40 may be preferably provided along the outer circumference of the track plate 10 as shown in fig. 1 to 4.
The stopper 40 may take a suitable form as long as it can be easily and stably pressed into the track plate 10 and the separator 20 at the time of construction or maintenance and can be easily taken out from between the track plate 10 and the separator 20 at the time of release positioning. Preferably, as shown in fig. 5, the limiting device 40 may include a first limiting plate 41, a second limiting plate 42, an elastic body 43, and a squeeze wedge 44, wherein the first limiting plate 41 and the second limiting plate 42 are disposed opposite to each other and are respectively in contact with the side surface of the track plate 10 and the side wall of the isolation case 20, the elastic body 43 is disposed in a space defined between the first limiting plate 41 and the second limiting plate 42, and the squeeze wedge 44 is used for wedging the space and is elastically wedged by the elastic body 43. Specifically, the first limiting plate 41 and the second limiting plate 42 may be fixed to the side surface of the track plate 10 and the side wall of the isolation casing 20, respectively, after the track plate 10 is set in place during re-limiting after construction or maintenance, the elastic body 43 may be positioned between the first limiting plate 41 and the second limiting plate 42, and then the wedge 44 is wedged into the space defined by the first limiting plate 41, the second limiting plate 42 and the elastic body 43, so that the elastic body 43 compresses the first limiting plate 41 and the second limiting plate 42, and the limiting device 40 is compressed between the side surface of the track plate 10 and the side wall of the isolation casing 20.
Wherein the wedge 44 has a shape that facilitates wedging, i.e., is formed with a large end and a small end. For example, in the embodiment shown in fig. 5, the wedge 44 is formed as a straight prism with a triangular cross section. In order to avoid the wedge 44 from being pushed out in the direction from the small end to the large end by the elastic force of the elastic member 43 after being wedged, it is preferable that the first and second limiting plates 41 and 42 are C-shaped as shown in fig. 5, and the limiting means 40 includes a third limiting plate 45 for being inserted into the space to abut against the folded edges of the first and second limiting plates 41 and 42 and to stop the large end of the wedge 44. Thus, after wedging the wedge 44, a third limiting plate 45 may be inserted between the flange and the large end of the wedge 44 to limit the shifting of the wedge 44. The first limiting plate 41 and the second limiting plate 42 may be straight-type bent C-shaped, i.e. the two side folds are straight and are perpendicular to the middle body.
To simplify the operation, the elastic body 43 may be fixed to the first limiting plate 41 and/or the second limiting plate 42 in advance. In addition, in order to enhance the wedging effect between the elastic body 43 and the wedge 44, it is preferable to match the contact surface shapes of the elastic body 43 and the wedge 44. Specifically, the elastic body 43 may be wedge-shaped, and the elastic bodies 43 are respectively fixed to sides of the first and second limiting plates 41 and 42 opposite to each other. Wherein the elastic bodies 43 are wedge-shaped, and opposite surfaces of the two elastic bodies 43 are matched and wedged with inclined surfaces of the extruding wedges 44 respectively. The wedges of the elastic body 43 and the wedge 44 may be set as required, and for simplifying the structure, as shown in fig. 5, the elastic body 43 may be a right triangle prism with a cross section, the wedge 44 may be a isosceles triangle prism with a cross section, and the oblique side of the cross section of the elastic body 43 corresponds to the waist of the wedge 44, so that the whole is a cuboid when the wedge is tightened.
As described above, the vibration damping track assembly of the present application may be used for railway tracks or urban tracks as desired, and may be used for an appropriate tunnel foundation 50 as desired. The tunnel foundation 50 is, for example, an open cut tunnel, a horseshoe tunnel, or a shield tunnel.
According to another aspect of the present application, there is provided a construction method of a vibration reduction track structure, wherein the construction method includes: s1, providing a vibration reduction track assembly; s2, fixing the isolation shell 20 and the tunnel foundation 50 through pouring.
In the technical scheme of the application, the isolation shell 20 can be fixed on the tunnel foundation 50 in a pouring manner, and when in maintenance, the track plate 10 is released from the isolation shell 20 without damaging pouring parts, so that the construction and maintenance can be conveniently and efficiently carried out.
Wherein, step S1 may include: the damper 30 is sandwiched between the track plate 10 and the isolation shell 20 and the track plate 10 is releasably positioned relative to the isolation shell 20 to form a damper track assembly. Preferably, the track plate 10 and the insulation case 20 may be positioned with each other after the insulation case 20 is cast-fixed to the tunnel foundation 50, that is, only the track plate 10 and the insulation case 20 may be pre-positioned with each other in step S1, and then pressed and positioned by the stopper 40 after step S2.
According to another aspect of the present application, there is provided a maintenance method of a vibration damping rail structure, wherein the vibration damping rail structure is the vibration damping rail structure of the present application, the maintenance method comprising: A1. releasing the positioning of the track plate 10 relative to the separator 20 to enable the track plate 10 to be removed from the separator 20; A2. maintaining the vibration reduction track structure; A3. the track plate 10 is positioned relative to the separator housing 20.
In the technical scheme of the application, the isolation shell 20 can be fixed on the tunnel foundation 50 in a pouring manner, and when in maintenance, the track plate 10 is released from the isolation shell 20 without damaging pouring parts, so that the construction and maintenance can be conveniently and efficiently carried out.
Wherein maintenance may comprise suitable operations, for example, step A2 may comprise replacing the track plate 10 and/or the damping member 30, as desired.
The construction method and the maintenance method of the vibration damping rail structure of the present application are described below with reference to the accompanying drawings.
In construction, the damper 30 and the rail plate 10 (the rail R may be preassembled to the rail plate 10 or the rail plate 10 may be assembled again when the damper rail assembly is installed) are first put into a predetermined position in the isolation case 20 from the upper opening of the isolation case 20, wherein the rail plate 10 and the isolation case 20 are respectively fixed with the first and second stopper plates 41 and 42, and the first and second stopper plates 41 and 42 are respectively fixed with the wedge-shaped elastic body 43, thereby completing the preassembly of the damper rail assembly body. The components of the pre-assembled damping track assembly main body can be manufactured according to specific requirements of construction, the pre-assembling process can be performed outside the construction site in advance, and then the damping track assembly main body can be sent to the construction site. The vibration reduction track assembly body may then be placed in a set position on the tunnel foundation 50, with the isolation shell 20 secured to the tunnel foundation 50 by casting concrete. The wedge 44 may then be wedged (e.g., driven in by a hammer blow) and a third stop plate 45 inserted such that the stop device 43 applies pressure to the track plate 10 and the isolation shell 20 to position the track plate 10 and the isolation shell 20 relative to each other. Finally, the vibration reduction track assembly may be positionally fine tuned (e.g., via a fastener system).
At the time of maintenance, the third limiting plate 45 may be removed to remove the wedge 44 (e.g., using a hammer blow mode), so that the track plate 10 may be released from the separator 20. Subsequently, corresponding maintenance, such as replacement of the vibration damper 30, can be performed. Thereafter, the track plate 10 may be replaced and the wedges 44 again wedged into and inserted into the third stop plate 45 such that the stop device 43 applies pressure to the track plate 10 and the separator housing 20 to reposition the track plate 10 and the separator housing 20 relative to one another.
The technical scheme of the application can greatly improve the working efficiency and save the cost. For example, for single track slab replacement, the replacement can be completed within 1 hour, the comprehensive construction efficiency can reach 100 meters/day, and the risk of outage is avoided as much as possible.
