Description
Technical field
It the utility model is related to Geotechnical Engineering, more particularly to talus slide area ballastless track roadbed structure.
Background technology
Talus slide is developed very much in China mountain area particularly Southwest Mountainous Areas, and building high-speed railway can not accomplish to pass round completely
All talus and landslide unfavorable geologic body.High-speed railway particularly non-fragment orbit railway, it is very strict to deformation requirements, no
But it is required that subgrade engineering meets strict Vertical Settlement, while harsher is required to horizontal distortion.When non-fragment orbit railway leads to
When crossing talus and slip mass, its Deformation control turns into crucial governing factor.Thus, there is an urgent need to a kind of by talus slide body
Ballastless track roadbed structure solves the problems, such as to exist, and should have the characteristics that economical, easy for construction, safe and environment-friendly.
Utility model content
The purpose of this utility model is to provide a kind of ballastless track roadbed structure by talus slide body, to realize talus
Meet the Deformation control requirement of non-fragment orbit high-speed railway with landslide area roadbed Vertical Settlement and horizontal distortion.
Technical scheme is as follows used by the utility model solves above-mentioned technical problem：
A kind of ballastless track roadbed structure by talus slide body of the present utility model, it includes：Inner side foundation pile and outer
Side base stake, in a row set along roadbed is longitudinally spaced, its underpart enters good ground through talus or slip mass；Loading plate and fill
Body, loading plate are arranged at the top of foundation pile and consolidated therewith, and filling body is filled at the top of loading plate；Inner side friction pile and outside
Friction pile, roadbed both sides are in a row arranged at along roadbed is longitudinally spaced, its underpart enters good ground through talus or slip mass；Anchor
Rope, along the longitudinally spaced setting of roadbed, its rear end is anchored in the good ground on the inside of roadbed below outer talus or slip mass, outer end
It is fixedly connected with inner side foundation pile.
The beneficial effects of the utility model are to efficiently solve talus slide area non-fragment orbit railway Vertical Settlement and level
The problem of Deformation control, have the characteristics that construction is simple, construction investment are low, there is popularizing application prospect, and meet wanting for environmental protection
Ask.
Brief description of the drawings
This specification includes following two width accompanying drawing：
Fig. 1 is a kind of sectional schematic diagram of ballastless track roadbed structure by talus slide body of the utility model.
Fig. 2 is a kind of floor map of ballastless track roadbed structure by talus slide body of the utility model.
Component name and corresponding mark are shown in figure：Inner side foundation pile 1a, outside foundation pile 1b, loading plate 2, filling body 3,
Inner side friction pile 4a, outside friction pile 4b, anchor cable 5, firm ground A, talus or slip mass B.
Embodiment
The utility model is further illustrated with reference to the accompanying drawings and examples：
Referring to Figures 1 and 2, the utility model is a kind of is included by the ballastless track roadbed structure of talus slide body：Inner side
Foundation pile 1a and outside foundation pile 1b, in a row set along roadbed is longitudinally spaced, its underpart enters good ground through talus or slip mass B
A；Loading plate 2 and filling body 3, loading plate 2 are arranged on the top of foundation pile 1 and consolidated therewith, and filling body 3 is filled at the top of loading plate 2
On；Inner side friction pile 4a and outside friction pile 4b, roadbed both sides in a row are arranged at along roadbed is longitudinally spaced, its underpart passes through rock
Heap or slip mass B enter good ground A；Anchor cable 5, along the longitudinally spaced setting of roadbed, its rear end is anchored at outer talus on the inside of roadbed
Or in below slip mass B good ground A, outer end is fixedly connected with inner side foundation pile 1a.
Loading plate 2 is by filling body 3 and the direct transfer line foundation pile 1 of train load, and as the exposure basis of filling body 3.
Inner side foundation pile 1a and outside foundation pile 1b directly takes on loading plate 2, filling body 3 and top train load, solves non-fragment orbit and erects
To the problem of sedimentation.Inner side friction pile 4a, outside friction pile 4b ensure rock as talus or slip mass B antiskid force structure
The resistance to overturning of heap or slip mass.Acted on using the tensioning of anchor cable 5, effectively the enhancing inner side foundation pile 1a flat deformation energy of water resistant
Power.
Reference picture 2, the inner side foundation pile 1a, outside foundation pile 1b and inner side friction pile 4a and outside friction pile 4b indulge along roadbed
Stagger laying to interval, its horizontal spacing is generally 4-6m, longitudinally spaced general 5-8m.The anchor cable 5 and inner side foundation pile 1a are pre-
Tensioning is fixedly connected, and stretching force is not more than the 50% of inner side foundation pile 1a limit bending resistance stress-bearing capabilities.It is the inner side friction pile 4a, outer
Side friction pile 4b sets quantity and size to meet talus or slip mass the safety factor of stability requirement.
The utility model a kind of ballastless track roadbed structure by talus slide body described above that simply explains through diagrams
Some principles, be not intended to by the utility model be confined to shown in and described concrete structure and the construction method scope of application
It is interior, therefore every corresponding modification for being possible to be utilized and equivalent, belong to the apllied the scope of the claims of the utility model.
