Specific embodiment
The exemplary scheme of structure disclosed in the utility model is described in detail in description.Although providing attached drawing is
In order to which the embodiments of the present invention is presented, but attached drawing need not be drawn by the size of specific embodiment, and certain features
It can be amplified, remove or disclosure to be better shown and explain the utility model is cutd open by office.
It hereinafter be used to describe certain directional terminologies of attached drawing, such as "upper", "lower", it will accordingly be understood that for it
It normal meaning and criticizes and often sees those related directions when attached drawing.Except as otherwise indicating, directional terminology described in this specification
Substantially conventional direction understood by one of ordinary skill in the art is referred to.It is wherein flat perpendicular to roadbed 8 when vertical reference observation attached drawing
The direction in face laterally refers to left and right directions when observation attached drawing.
Fig. 1 shows ballastless track structure schematic diagram provided by the utility model, include from bottom to top by rubble or
AB group filler etc. be laid with made of roadbed 8, generally formed as concreting or poured as armored concrete made of supporting course 4
(supporting course armored concrete when being made of also referred to as base plate), generally poured as armored concrete made of track plates
3, the sleeper 2 that is fixed in the track plates 3 is attached to the steel track 1 of the sleeper 2 and is laid on roadbed 8 and supporting course 4
Between adjustment layer 5.Reduction or ascending rails elevation can be achieved in height by adjusting the adjustment layer 5.
Specifically, the adjustment layer 5 in the utility model may be structured to the multiple plate-like pieces 9 removably vertically stacked,
I.e. when not using additional fasteners, multiple plate-like piece 9 can slide relative to each other under external force.It should be noted that
It is that the compression strength and rigidity of the plate-like piece 9 should be greater than the compression strength and rigidity of roadbed 8.
The thickness of multiple plate-like piece 9 is chosen in the range of 1 millimeter to 10 centimetres simultaneously, preferably in the range in ladder
Degree distribution.For example, which uses 8 plate-like pieces altogether, the thickness of this 8 plate-like pieces may respectively be 1 millimeter, 2 millimeters,
5 millimeters, 1 centimetre, 2 centimetres, 3 centimetres, 5 centimetres and 10 centimetres.It as a result, can be according to the geographical environment and weather for being laid with non-fragment orbit
Etc. factors determine choose each plate-like piece 9 thickness and required plate-like piece quantity, only when needing adjustable track elevation
Need to be inserted into or remove the plate-like piece with the thickness corresponding to desired adjustment amount can be completed adjusting.The plate-like piece 9 can be used pre-
The steel plate with specific thicknesses or the steel plate by rubber coated for first preparing completion.
In order to guarantee after extracting and increasing plate-like piece 9, entire adjustment layer 5 will not generate transversion malposition, preferably should
Multiple plate-like pieces 9 and other track structures carry out detachably connected, such as are bolted with supporting course 4, wherein the bolt 7 to
Preferably vertically plate-like piece 9 should be connect with supporting course 4 through the supporting course 4 of multiple plate-like piece 9 and arrangement thereon less, it should
One end that bolt 7 and nut are cooperatively connected exposes outside the supporting course 4 towards the side of track plates 3.Alternatively, it can also adjust
To limit, adjustment layer 5 is issuable to be slid laterally both lateral sides setting common position-limit mechanism of those skilled in the art of layer 5 etc..
Concrete layer 6 is laid with preferably on roadbed 8 before being laid with adjustment layer 5, preferably in the intensity example of the concrete layer 6
Continue to be laid with adjustment layer 5 after reaching 3Mpa or more such as intensity, the final set strength of the concrete layer is not less than 15MPa.The coagulation
Soil layer can be to the transition that the adjustment layer of arrangement thereon is supported, and is used as between roadbed and adjustable flood.
The method that track elevation is reduced using structure according to the present utility model is summarized as follows: measurement track first is high
Journey determines track lowering amount.In next step, it scoops away the roadbed 8 around adjustment layer 5 from side between road shoulder side or line, exposes adjustment layer 5.Under
One step unclamps bolt 7, it is made to remove plate-like piece 9 and supporting course 4.In next step, the support devices such as jack, which can be used, to be supported
Layer 4 and its top structure jack up, and extract the plate-like piece 9 of specified quantity and/or certain height out on demand according to track lowering amount.Next,
By means of jack by supporting course 4 and its top structure fall until be connected to remaining plate-like piece 9 and in the process by means of
Bolt 7 reconnects plate-like piece 9 and supporting course 4.Finally the roadbed 8 around adjustment layer 5 is restored.
The method of track elevation and the method for above-mentioned reduction track elevation are improved using structure according to the present utility model
The main distinction in place of be: firstly, track up-regulation amount need to be determined；Secondly, supporting course 4 and its top are tied using jack
After structure jacks up, it is inserted into the plate-like piece 9 of specified quantity and/or certain height on demand according to up-regulation amount.Remaining step and above-mentioned drop
The step of low orbit elevation, is essentially identical.
By above description as it can be seen that adjusting track elevation using ballastless track structure according to the present utility model without will be complete
Portion's dismantling of track improves efficiency, reduces cost.Only part arch rail can be completed in the skylight activity duration in this method simultaneously
The amendment in road has ensured the normal operation of train.In addition, the extraction and increase by adjusting plate-like piece in layer can be realized easily
The decline and rising of track elevation, it is convenient to operate, lower to worker operation skill requirement.
Although the utility model is described referring to example embodiment, it will be understood by those skilled in the art that
It is that can carry out various changes under conditions of without departing from the scope of the utility model and its component can be equivalently replaced.
In addition, under conditions of without departing from the base region of the utility model, it is practical new in order to make specific condition or material be suitable for this
The introduction of type can carry out multinomial modification.The utility model is intended to be not limited to public as desired implementation the utility model institute as a result,
The specific embodiment opened, but will include all embodiments fallen within the scope of the appended claims.
