Description
Technical field
This utility model belongs to that middle low speed magnetic suspension is low puts line area, more particularly, to middle low speed
Magnetic suspension traffic engineering is low puts circuit two-wire location support rail beam internode position limiting structure.
Background technology
Middle low speed magnetic suspension track traffic belongs to a kind of novel traffic mode, current both domestic and external studies into
The most less, the circuit minority especially of operation is opened in the whole world.The most only in March, 2005, Japan built
Middle low speed magnetic suspension railway comercial operation line-the East Hillside Line of opening and in June, 2014 Korea S open-minded
Middle low speed magnetic suspension railway business operating line.And the middle low speed magnetic suspension traffic of China only has state at present
Anti-University of Science and Technology test wire, Green City Mountain test wire, Tangshan experiment line, but do not put into effect formal
Circuit, and all based on elevated structure, rarely seen about the low research put in terms of circuit support rail girder construction with
Application.
In conventional general speed wheel rail railway, circuit is big to the adaptation ability of deformation, the settlement Control to roadbed
Standard-required is the most loose, thus has substantial amounts of circuit to build on fill subgrade；Current rail without the tiny fragments of stone, coal, etc.
Road high-speed railway, although requiring the settlement after construction of roadbed under line very strict, still has many circuits to repair
It build on fill subgrade, it is desirable under line, roadbed is built by structures, there is enough intensity and resistance to deformation
Ability, steady in a long-term under various natural environment.And middle low speed magnetic suspension traffic line magnetic suspension train
The mode using " embracing rail to travel " is run, and the F rail of middle low speed magnetic suspension traffic line is the shortest by one
Rail scene is spliced, and leaves rail break joint, wanting of the even running of magnetic suspension train F rail to be met
Ask, be necessary for ensureing by line construction of putting low under rail, thus, magnetic suspension traffic circuit is to sub rail foundation
Deformation controlling standards and the requirement of ride comfort higher, especially for parallel double of two railway lines
Line structure, the control of the deformation controlling standards of its sub rail foundation is even more important.
In order to prevent excessive temperature stress and differential settlement, traditional support rail girder construction typically uses
Often joint 10～30m arranges expansion joint, and under support rail beam, basis is by the earth structure of rock and soil constitution, is subject to
The impact of the factor such as landform, geological conditions, quality is the most wayward, therefore load and various from
It is easily generated differential settlement under right and various effect of natural environment, there will be unavoidably between adjacent support rails beam
Inconsistent settlement after construction, causes support rail beam to produce faulting of slab ends, thus affects the ride comfort of F rail, even
F rail may be caused to produce the problem such as faulting of slab ends, deformation, the normal fortune of levitation train time serious, will be affected
Battalion.
