Description
Technical field
The present invention relates to technical field of rail traffic, more particularly to a kind of assembled ballastless track system.
Background technology
Rail system is direct vehicle load and the key structure system for keeping vehicle smooth-going to run in rail traffic,
Play the role of forming a connecting link in entire wheel rail system, rail system is generally by rail, fastener, sleeper, railway roadbed and lower part branch
Support the compositions such as layer.Rail system is divided into Ballast track and non-fragment orbit two types, the road of Ballast track according to the form of railway roadbed
Bed is built by railway ballast, and the railway roadbed of non-fragment orbit is built by reinforced concrete structure.Non-fragment orbit is compared with Ballast track
Compared with having the apparent advantages such as globality is more preferable, stability is good, Trajectory Sets retentivity is good, maintenance workload is few.
Non-fragment orbit most rises early in Europe and Japan, introduces China later, by nearly development in 20 years, non-fragment orbit exists
It is developed in Chinese Railway process of construction, and innovation and development has gone out a variety of non-fragment orbit types.Non-fragment orbit according to
The manufacture of track plates is divided into two kinds of major class of precast slab type ballastless track and cast-in-place non-fragment orbit.Precast slab type ballastless track generation
CRTSI, CRTSII, CRTSIII the plate-type non-fragment orbit for having China of table, Japanese slab track, German rich panel
Formula track etc..Cast-in-place non-fragment orbit representative has CRTSI, CRTSII type double-block type ballastless track of China, Chinese bearing
Block type ballastless track, German 2000 ballastless track system of radar and the general woods non-fragment orbit of the rising sun etc..
Non-fragment orbit has obtained large-scale application, either state-owned railroads field or city in the world at present
Field of track traffic, and have extensive foreground, but still have some problems to be solved, i.e., its adjustment capability compared with
Difference, can repair ability it is poor, when infrastructure occur it is larger sedimentation, horizontal displacement or arch deformation when, non-fragment orbit can not
Be adjusted, therefore, non-fragment orbit the poor area of geological conditions and deformation can not or area more rambunctious paving
And if developing hindered.In addition, prefabricated platy ballastless track structure, the scale of construction of track plates is larger, in manufacture control, fortune
During defeated, site operation and repair are replaced, there is more problem.In the non-fragment orbit being laid at present, partly without the tiny fragments of stone, coal, etc.
Rail system generates destruction because the deformation of infrastructure is excessive, can not normal use, repair replacing construction it is long, difficulty is big, sternly
The normal operation of rail traffic is affected again.Therefore, ballastless track system needs in terms of replaceable, easy-maintaining, big adjustment capability
Carry out deeper into optimization innovation, it is existing to solve the problems, such as.
Invention content
It is an object of the invention to overcome the above-mentioned deficiency in the presence of the prior art, a kind of assembled non-fragment orbit is provided
System.
In order to achieve the above-mentioned object of the invention, the present invention provides following technical schemes：
A kind of assembled ballastless track system, including rail, fastener system, assembled track plates, filled layer and lower part base

Assembled track plates include laterally at least two cell boards being connected with each other, and are longitudinally also wrapped along the assembled track plates
Include the cell board of at least two interconnections.
The present invention mainly has following both sides significant difference compared to existing ballastless track system：
One is using assembled track plates, assembled track plates are assembled by several cell boards, by body
The fragment-free track slab that amount is big, weight is heavy breaks the whole up into parts.Since the cell board scale of construction is small, light-weight, prefabrication difficulty reduces, assembly
At track plates deformation it is small, in the construction process, transport and lifting are facilitated, in addition, during operation, if base under line
Plinth deformation is larger, and non-fragment orbit is replaced detachably at the unit harden structure of fritter and maintenance difficulty is greatly reduced, enhance rail
The adjustment capability of road system and can repair ability.
The second is original pedestal is eliminated, and as a result of assembled track plates, the stress of entire rail system, power transmission
Well, at this point, the pedestal of track plates lower part can be cancelled.The workload that pours of on-site concrete can be reduced by cancelling pedestal, be reduced
While construction material dosage, the speed and efficiency of construction are improved.In the case of rail superior portion spatial altitude is more limited,
Cancel pedestal, the occupancy height of rail system can also be reduced.The present invention is especially suitable for the situations that infrastructure rigidity is larger.
Preferably, it is additionally provided with track on the assembled track plates, at this point, fastener system is mounted on track,
Track can not be set, fastener system can be directly installed on cell board.
Preferably, the filled layer is self-compacting concrete layer, CA screeds, epoxy resin layer or meets mechanical property and want
The other materials layer asked.
Preferably, the infrastructure includes tunnel basis, bridge foundation and foundation of road bed, this rail system is applicable to
Various infrastructures, adaptability are good.
Preferably, the assembled track plates are embedded with the connection various built-in fittings such as reinforcing bar or truss bars, can not also
If built-in fitting.
Preferably, the shape of the cell board is rectangle or wedge shape.When being laid with straight line location, by identical unit

When more special, also cell board can be designed to triangle, diamond shape, parallelogram, trapezoidal etc. according to actual requirement.Therefore,
The present invention is good to the adaptability for being laid with location, solves asking for the fragment-free track slab bad adaptability that original scale of construction is big, weight weighs
Topic, can especially assemble the track harden structure with curvature, greatly reduce the difficult processing of the track harden structure with curvature
Degree.
Preferably, the assembled track plates include that there are many various sizes of cell boards, can be by different sizes
Cell board make standard component, by the splicing of various sizes of cell board, can be assembled into various different lengths, width,
The track plates of curvature meet practice of construction requirement.
Preferably, detachable connection between the adjacent cell board, facilitates installation, dismounting and repair.
Preferably, the bindiny mechanism includes the installation room being preset on each cell board, each installation
The interface channel that room is communicated with, and run through and connect the connector of the two neighboring interface channel, the connector
Both ends are separately fixed on the two neighboring installation room.The installation room is outdoor hole recessed on cell board, installs room
Position be set to the edge of cell board, the installation room is connected with interface channel, interface channel inside cell board,
Cell board can preset installation room and interface channel when processing, to facilitate connection.After the completion of cell board assembly, may be selected will
