Description
Technical field
The invention belongs to railway engineering technology fields, and in particular to a kind of to reduce subgrade settlement deformation to lacing wire material U-type groove
Railway bed structure.
Background technology
Railway bed mostly uses discrete material and carries out landfill according to certain compactness and the slope gradient stablized at present, and auxiliary
With ballast slope protection form.Since discrete material compactness and current construction technology level are limited, can mostly be sent out in roadbed ontology
Raw larger sedimentation, roadbed side slope（Especially side ending position）Slump or depression, when basement process is uneven sometimes, iron can occur
The differential settlement ballast of road roadbed strictly limits application range of the railway bed form in high-grade railway.
Invention content
Reducing the railway bed structure that subgrade settlement deforms to lacing wire material U-type groove the object of the present invention is to provide a kind of, gram
It is big to take existing railway bed ontology sedimentation（Uniform settlement and differential settlement）, take up an area wide and basement process expense proportion compared with
Big defect.
The technical solution adopted in the present invention is：
Reduce the railway bed structure of subgrade settlement deformation to lacing wire material U-type groove, it is characterised in that：
The bottom of the railway bed structure is provided with the upward reinforced concrete U-shaped slot of notch, is filled out in reinforced concrete U-shaped slot
Roadbed landfill material has been built, has been flushed with reinforced concrete U-shaped groove top edge at the top of roadbed landfill material and in top setting railway road
Railway track structure is arranged in slag, railroad ballast top；
It is horizontally arranged in reinforced concrete U-shaped slot to lacing wire material, to lacing wire material both ends stretching reinforced concrete U-shaped slot and admittedly
It is fixed.
Reinforced concrete U-shaped slot includes the upward upright side plate of horizontal bottom plate and both sides, and reserved pair is provided on side plate
Lacing wire material hole is pierced by and fixes to lacing wire material hole from reserved to lacing wire material both ends.
To lacing wire material, longitudinally spaced setting is multiple rows of in reinforced concrete U-shaped slot, often arranges vertically arranged multiple tracks.
Reserved is pvc pipe prefabricated in reinforced concrete U-shaped slot side plate to lacing wire material hole.
Roadbed landfill material top surface is provided with one layer of flexible water partition material.
It is steel pipe or reinforcing bar to lacing wire material.
Reinforced concrete U-shaped slot side plate is fixed on bolt fastening to lacing wire material transverse ends end.
The present invention has the following advantages：
The present invention utilizes armored concrete（Or rigidity is larger）U-type groove is made in material, by strictly limiting U-type groove to lacing wire material
The outside deformation of both sides side wall, the compactness of U-type groove inner stuffing is strictly controlled by construction requirement, can effectively reduce roadbed
The sedimentation of ontology；Reinforced concrete U-shaped groove sidewall is more reliable and more stable relative to side slope protection, more rigid, will not be because of side slope
Collapse and cause body distortion, and the upright side wall of U-type groove can effectively reduce roadbed bottom floor space and reduce at ground
Area is managed, and the U-type groove bottom plate of relative stiffness makes the sedimentation of substrate tend to be uniform, rather than " parabola " type of flexible foundation
Sedimentation, effectively reduces differential settlement.
Railway bed form of the present invention can be applied to high-grade railway subgrade works, the subway engineering by city, increase
The overall stability of side slope, the sedimentation for effectively reducing roadbed ontology and floor space.Itself have and gathers materials on the spot, rapidity of constructing,
Material environmental protection, the advantages of saving construction materials, and in " billboard " or " cultural wall " that can be used as large area by region, with
Local or zonal streetscape height fusion, if in conjunction with vertical planting technology, can be effectively formed environmentally protective channel, have
Wide popularizing application prospect.

Specific implementation mode
The present invention will be described in detail With reference to embodiment.
The present invention relates to a kind of railway bed structure reducing subgrade settlement deformation to lacing wire material U-type groove, the railway roads
The bottom of based structures is provided with the upward reinforced concrete U-shaped slot 5 of notch, and roadbed landfill has been filled in reinforced concrete U-shaped slot 5
Material 7,7 top of roadbed landfill material flush with 5 apical margin of reinforced concrete U-shaped slot and railroad ballast 3, railway road are arranged in top
Railway track structure 2 is arranged in 3 top of slag.7 top surface of roadbed landfill material is provided with one layer of flexible water partition material 4, using two cloth one
Film geotextiles or compound water-stop sheet.
It is horizontally arranged in reinforced concrete U-shaped slot 5 to lacing wire material 6, reinforced concrete U-shaped is stretched out to 6 both ends of lacing wire material
Slot 5.To lacing wire material 6, longitudinally spaced setting is multiple rows of in reinforced concrete U-shaped slot 5, and often arranging can vertically set according to the height of side plate
Set twice or multiple tracks.Reinforced concrete U-shaped slot 5 includes the upward upright side plate of horizontal bottom plate and both sides, is provided on side plate
It reserves to lacing wire material hole 1, it is pvc pipe prefabricated in 5 side plate of reinforced concrete U-shaped slot to reserve to lacing wire material hole 1, to lacing wire
6 both ends of material are pierced by lacing wire material hole 1 from reserved.Reinforced concrete U-shaped slot 5 can cast in situs, also can prefabrication, scene dress
Match.
