Description
Technical field
This utility model belongs to that middle low speed magnetic suspension traffic engineering is low to put Line technology field, low more particularly, in
Fast magnetic floats single line excavation location support rail beam transition section structure pattern.
Background technology
Middle low speed magnetic suspension track traffic belongs to a kind of novel traffic mode, and achievement in research both domestic and external is less, the whole world
The circuit for opening operation is even more minority.The middle low speed magnetic suspension railway business that only in March, 2005 Japan's construction at present is opened is transported
The middle low speed magnetic suspension railway business operating line that line-the East Hillside Line and in June, 2014 Korea open.And the middle low speed of China
Magnetic suspension traffic only National University of Defense technology's test wire, Green City Mountain test wire, Tangshan experiment line at present, but do not put into effect
Formal circuit, and based on elevated structure, it is rarely seen about elevated structure and the low research put in terms of line transition segment structure and
Using.
In wheel rail high speed railway, there is substantial amounts of bridge changeover portion roadbed, high-speed railway changeover portion roadbed is adopted mostly
Trapezium structure, employs cement stabilized graded macabam and fills in trapezoidal scope, and employs the compacting higher than non-changeover portion roadbed
Require.During built high-speed railway operation, often there is non-fragment orbit protuberance, gap, grout in bridge transition segment limit
Etc. disease.The reason for this disease, be mostly because changeover portion roadbed is remained by the earth structure of rock and soil constitution, changeover portion
After roadbed is laid a railway track, certain sedimentation still can occur, there is poor (the specification permission settlement after construction of certain settlement after construction with bridge abutment
Difference is not more than 5mm), because high-speed railway adopts seamless track steel rail, allow in settlement after construction difference scope, to have no effect in specification
Normal operation, but the diseases such as non-fragment orbit protuberance, gap, grout can be caused, need timely repair and maintenance.
The F rails of medium-and low-speed maglev traffic line are spliced using fishplate bar scene by a short rail successively, and are left between rail
Seam, meets the ride comfort of the F rails of magnetic-levitation train even running requirement, to lean on works under rail to ensure substantially.It is low to put circuit location,
Basis is, by the earth structure of rock and soil constitution, to be affected by factors such as landform, geological conditions under support rail beam, and quality is not relatively easily-controllable
System, under load and the effect of various factor of natural environments differential settlement is also easy to produce, and can be occurred unavoidably and elevated structure bridge bridge
The inconsistent settlement after construction of platform, generation settlement after construction is poor, and low circuit of putting occurs in that differential settlement with bridge abutment position, necessarily affects
The ride comfort of F rails, in some instances it may even be possible to cause F rails to produce the problems such as faulting of slab ends, deformation, when serious, will affect the normal fortune of maglev vehicle
Battalion.

Displacement, improves the lateral stability of structure.One end of support rail beam overlaps with bridge abutment 12, makes low to put circuit support rail beam and bridge
The sedimentation of the lap position of abutment 12 is consistent, it is to avoid bridge abutment 12 and low putting produce between circuit support rail girder construction faulting of slab ends sedimentation；It is low
Put the other end of circuit armored concrete support rail beam base plate 2 be embedded in it is stable it is low put in line construction, its sedimentation puts circuit with low
Structure is consistent, is put line construction Jing basement process and is filled after compacting sedimentation value in controlled range due to low, therefore, support rail
Sedimentation between beam two ends be located at bridge abutment 12 and it is low put between line construction, close linear change, it is achieved thereby that overhead
Bridge structure and the low sedimentation transition put between line construction, it also avoid faulting of slab ends, and the smooth-going of transition segment limit F rails has been effectively ensured
Property.
Wear-resisting sliding layer 16 is arranged between armored concrete support rail beam base plate 2 and bridge abutment 12, by resistance to mill sliding
The effect of layer 16, can to a certain extent release the rotation that support rail beam is likely to occur under the load actions such as relative settlement, temperature
Constraint, and the dynamic stress cushioning effect of bridge abutment 12 is transferred to magnetic-levitation train, it also avoid support rail beam and bridge abutment
Abrasion and stress concentration between 12 causes the partial pressing of structure to destroy.
The specific making step of this utility model is as follows：
