Abstract
The utility model relates to a railway shock -absorbing structure, including the embankment be provided with the foundation bed on the embankment, and be provided with track bed along foundation bed length direction on the foundation bed be provided with one between foundation bed and the embankment and be used for the absorbing buffer layer, just be in the below of buffer layer still is provided with the ascending vibrations reflex arc of a plurality of openings. The utility model discloses the special design of each level order draws through the repetition test, is not simple stack, and this railway shock -absorbing structure not only is provided with effectively shock attenuation, inhales the buffer layer of shake under the circumstances that satisfies whole railway intensity demand, is provided with the vibrations reflex arc of being made by reinforced concrete in addition, can reflect the part vibrations to the foundation bed, can further stop the vibration to be propagated to the embankment, can show and reduce the violent vibration that causes behind the existing circuit expansion revamp.
Description
Technical field
The utility model relates to railway engineering field, particularly relates to a kind of railway shock-damping structure.
Background technology
Along with economic, social fast development, railway passenger and goods flow also increases substantially, the existing iron of major partThe needs that the inadaptable transport of the capacity on road increases, must carry out capacity expansion revamping. But existing line is being expandedIn energy improvement project, will occur many new problems, the aggravation that wherein causes vibration is inevitable.
After circuit capacity expansion revamping, due to the lifting of load-carrying and speed, must cause larger vibration, for itBefore can meet vibration require some residential buildings or industrial premises, after capacity expansion revamping, probably can not meetThis respect requirement. For reducing the impact of vibration on surrounding enviroment, we must take the suitable vibration isolation measure that subtracts,Promote environmental quality along the line, realize sustainable development.
Utility model content
Therefore,, for above-mentioned problem, the utility model proposes a kind of railway shock-damping structure.
For realizing above-mentioned technical problem, the solution that the utility model is taked is: a kind of railway shock-damping structure,Comprise embankment, on described embankment, be provided with bedding, and be provided with along bedding length direction on described beddingBallast bed of track is provided with a cushion for damping between described bedding and embankment, and in described bufferingThe below of layer is also provided with plurality of openings vibrations reflex arc upwards.
Further improved: described cushion comprises that high polymer polyurethane kind injecting paste material layer or bubble mixLight soil injecting paste material layer.
Further improved: described vibrations reflex arc comprises that surface is provided with the armored concrete of arc cavityPlate.
Further improved: the thickness of described cushion is 30-50mm.
By adopting aforementioned techniques scheme, the beneficial effects of the utility model are: the each level of the utility modelThe particular design of order is to draw through repetition test, is not simple stack, and this railway shock-damping structure is meetingIn the situation of entirety railway strength demand, be not only provided with the cushion of effectively damping, shock-absorbing, Er QiesheBe equipped with the vibrations reflex arc of being made by armoured concrete slab, part vibrations can be reflexed to bedding, can be furtherStop vibration to be propagated to embankment, can significantly reduce the high vibration causing after existing line capacity expansion revamping.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of described vibrations reflex arc.
Detailed description of the invention
Now with specific embodiment, the utility model is further illustrated by reference to the accompanying drawings.
With reference to figure 1 and Fig. 2, the utility model embodiment discloses, and a kind of railway shock-damping structure, comprises roadDike 1 is provided with bedding 2, and is provided with along bedding 2 length directions on described bedding 2 on described embankment 1Ballast bed of track 3 is provided with a cushion 4 for damping, in this enforcement between described bedding 2 and embankment 1Cushion 4 described in example adopts high polymer polyurethane kind injecting paste material layer, this injecting paste material high-strength light, and energyForm fast Stability Analysis of Structures body, after slip casting, open to traffic comes into operation rapidly, in actual production processAlso air bubble mix light-textured soil injecting paste material layer can be used as required, identical effect can be reached, and in this realityThe thickness of executing cushion 4 described in example is 39mm, and in actual production, the thickness of this cushion 4 needs onlyBetween 30-50, all can implement the purpose of this utility model, and below described cushion 4, also be provided with multipleThe vibrations reflex arc 5 of several opening upwards, and described vibrations reflex arc 5 comprises that surface arranges in the present embodimentThere is the armoured concrete slab 7 of arc cavity 6.
By adopting aforementioned techniques scheme, the beneficial effects of the utility model are: the each level of the utility modelThe particular design of order is to draw through repetition test, is not simple stack, and this railway shock-damping structure is meetingIn the situation of entirety railway strength demand, be not only provided with the cushion of effectively damping, shock-absorbing, Er QiesheBe equipped with the vibrations reflex arc of being made by armoured concrete slab, part vibrations can be reflexed to bedding, can be furtherStop vibration to be propagated to embankment, can significantly reduce the high vibration causing after existing line capacity expansion revamping.
Although specifically show and introduced the utility model, this technical side of specific implementation in conjunction with preferred embodimentCase method and approach are a lot, and the above is only preferred embodiment of the present utility model, but affiliated fieldTechnical staff should be understood that the spirit of the present utility model and the model that limit not departing from appended claimsIn enclosing, can make a variety of changes the utility model in the form and details, be of the present utility modelProtection domain.
