Abstract
The utility model relates to the railway bed structures that a kind of pair of lacing wire material U-type groove reduces subgrade settlement deformation, bottom is provided with the upward reinforced concrete U-shaped slot of notch, roadbed landfill material has been filled in reinforced concrete U-shaped slot, railroad ballast is flushed and be arranged at the top of roadbed landfill material with reinforced concrete U-shaped groove top edge, railway track structure is set above railroad ballast；It is horizontally arranged in reinforced concrete U-shaped slot to lacing wire material, reinforced concrete U-shaped slot is stretched out to lacing wire material both ends.On the one hand the utility model passes through lateral deformation of the armored concrete to drawing U-type groove to greatly limit roadbed ontology, pass through landfill roadbed Body filler or casting concrete in the confined space for having lateral confinement, the sedimentation for controlling roadbed ontology of high degree；On the other hand roadbed bottom land occupation width is greatly saved again, saves a large amount of expropriation of land and basement process area.
Description
Technical field
The utility model belongs to railway engineering technology field, and in particular to a kind of pair of lacing wire material U-type groove reduces subgrade settlement
The railway bed structure of deformation.
Background technique
Railway bed mostly uses discrete material to carry out landfill according to certain compactness and stable slope gradient 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
Slump or depression, when basement process is uneven sometimes, iron can occur for raw biggish sedimentation, roadbed side slope (especially side ending position)
The differential settlement ballast of road roadbed strictly limits application range of the railway bed form in high-grade railway.
Summary of the invention
The purpose of the utility model is to provide the railway bed knots that a kind of pair of lacing wire material U-type groove reduces subgrade settlement deformation
Structure overcomes existing railway bed ontology to settle big (uniform settlement and differential settlement), land occupation extensively and shared by basement process expense
The defect of large percentage.
The technology employed by the present utility model is
A kind of pair of lacing wire material U-type groove reduces the railway bed structure of subgrade settlement deformation, it is characterised in that:
The bottom of the railway bed structure is provided with the upward reinforced concrete U-shaped slot of notch, reinforced concrete U-shaped slot
Roadbed landfill material has inside been filled, flushed at the top of roadbed landfill material with reinforced concrete U-shaped groove top edge and iron is set in top
Railway track structure is arranged in way slag, railroad ballast top；
It is horizontally arranged in reinforced concrete U-shaped slot to lacing wire material, reinforced concrete U-shaped slot is stretched out simultaneously to lacing wire material both ends
It is fixed.
Reinforced concrete U-shaped slot includes the upward upright side plate of horizontal bottom plate and two sides, is provided with reserved pair 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, multiple rows of, every vertically arranged multiple tracks of row is arranged in longitudinal gap in reinforced concrete U-shaped slot.
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 utility model has the advantage that
U-type groove is made using armored concrete (or rigidity is biggish) material in the utility model, by stringent to lacing wire material
The outside deformation of U-type groove both sides side wall is limited, the compactness of construction requirement strict control U-type groove inner stuffing, Ke Yiyou are passed through
Effect reduces the sedimentation of roadbed ontology；Reinforced concrete U-shaped groove sidewall is more reliable and more stable relative to side slope protection, more rigid,
Will not cause body distortion because of collapsing for side slope, and the upright side wall of U-type groove can effectively reduce roadbed bottom occupied area and
Reduce basement process area, and the U-type groove bottom plate of relative stiffness makes the sedimentation of substrate tend to be uniform, rather than flexible foundation
The sedimentation of " parabola " type, effectively reduces differential settlement.
The utility model railway bed form can be applied to high-grade railway subgrade works, the subway engineering by city,
Increase the overall stability of side slope, effectively reduce the sedimentation and occupied area of roadbed ontology.Itself have and gather materials on the spot, construction is fast
Degree, material environmental protection, is saved the advantages of constructing materials, and in " billboard " that can be used as large area by region or " culture
Wall " is merged with local or zonal streetscape height, if can be effectively formed environmentally protective logical in conjunction with vertical planting technology
Road has broad popularization and application prospect.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model.
