Description
Technical field
The utility model relates to technical field of rail traffic, in particular to a kind of assembled ballastless track system.
Background technique
Rail system is direct vehicle load and the key structure system for keeping vehicle smoothly 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 composition 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 constructed by railway ballast, and the railway roadbed of non-fragment orbit is constructed 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
The CRTS I for having China, the CRTS II, CRTSIII plate-type non-fragment orbit of table, Japanese slab track, German Bo Ge
Slab track etc..Cast-in-place non-fragment orbit representative has the CRTS I of China, CRTS II type double-block type ballastless track, Chinese
Support 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 prospect, 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
If being hindered with development.In addition, prefabricated platy ballastless track structure, the scale of construction of track plates is larger, in manufacture control, fortune
In defeated, site operation and maintenance replacement, there is more problem.In the non-fragment orbit being laid at present, partially without the tiny fragments of stone, coal, etc.
Rail system generates destruction because the deformation of infrastructure is excessive, can not normal use, maintenance 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.
