The split type roadbed structure has the advantages that the load bearing capacity is high, the occupied space is small, and safe operation of a newly built line and existing structures can be guaranteed.
Description
Technical field
The utility model relates to the railway bed building field, relates in particular to a kind of split type road structure.
Background technology
Roadbed is the banded structure thing as track or road bed of building according to technical requirements.It also will bear train or vehicular load, thereby it is the important component part of whole railway except bearing itself ground deadweight and track or road surface gravity.When the construction of highway or railway is subject to other condition restriction, when the works such as the existing bridge of necessary next-door neighbour pass through, if adopt common soil subgrade, can produce lateral earth pressure to works such as existing bridges, and the bridge foundation cushion cap produced vertical pressure, thereby affect the safety of existing bridge.
In order to address the above problem, two kinds of methods are arranged usually.First method is to adopt the retaining structure closing slopes such as barricade, U-shaped groove.Second method is to adopt bridge to cross over.Yet, when adopting first method, because the size of described retaining structure itself takies certain space and described retaining structure can with stressed biography to shallow layer foundation, affect the basic safety of the works such as existing bridge.When adopting second method, because the bridge pier of described bridge, key dimension etc. are larger, and the construction technology relative complex, be close to existing bridge construction, can bring construction hidden danger.
Therefore, be necessary to provide a kind of split type road structure to overcome defects.
The utility model content
The purpose of this utility model provides a kind of split type road structure, takes up room little and can guarantee the safe operation of newly-built circuit and existing structure thing.
To achieve these goals, the utility model provides a kind of split type road structure, comprises more piece roadbed unit, every joint roadbed unit comprises pile plate foundation, roadbed wall and pallet, the roadbed wall is fixed on the pile plate foundation, and pallet is fixed on the roadbed wall, and the top of pallet is provided with gear tiny fragments of stone, coal, etc. groove.
Particularly, the bottom surface of gear tiny fragments of stone, coal, etc. groove is arranged with weathering.
Particularly, the gradient of weathering is 4%.
Particularly, the pallet both sides are provided with the spilled water hole of a plurality of lateral direction penetratings, are provided with gutter in the spilled water hole.
Particularly, the distance between adjacent two spilled water holes is 5 ~ 10m.
Particularly, be provided with successively waterproofing course, topping and railway ballast layer in the gear tiny fragments of stone, coal, etc. groove.
Particularly, the pallet both sides also are fixed with the sidewalk.
Particularly, pile plate foundation comprises loaded plate and the stake of many foundation, loaded plate be located at many foundation stake top and with the stake of many foundation be the integral type structure, the bottom surface of loaded plate is positioned at underground.
Particularly, the spacing of adjacent two pile bases is greater than 3m.
Particularly, be provided with the shrinkage joint between the adjacent two joint roadbed unit, the seam at shrinkage joint is wide to be 2 ~ 5cm, is provided with pitch hemp cut layer or waterproofing course in the shrinkage joint.
Compared with prior art, the split type road structure of the utility model is pile plate foundation, the combining form of roadbed wall and pallet, thereby, this combining form takes up room little, and during construction, road structure of the present utility model can unsettled leap contiguous structure with it, track or road surface load both can have been born, load is effectively transmitted to the ground deep, thereby, reasonably avoiding the phase mutual interference of construction period and later stage operation between the adjacent structure, and then, not only guaranteed construction and the operation security problem of newly built railway roadbed, and, existing buildings and basic safety thereof guaranteed.
By following description also by reference to the accompanying drawings, it is more clear that the utility model will become, and these accompanying drawings are used for explaining embodiment of the present utility model.
Description of drawings
Fig. 1 is the structural representation of the split type road structure of the utility model.
Fig. 2 is the position view of the split type road structure of the utility model and existing bridge pier.
The specific embodiment
With reference now to accompanying drawing, describe embodiment of the present utility model, similar element numbers represents similar element in the accompanying drawing.
As shown in Figure 1, the split type road structure of the present embodiment comprises more piece roadbed unit, and the length of every joint roadbed unit is 10 ~ 20m, is provided with the shrinkage joint between the adjacent two joint roadbed unit, the seam at shrinkage joint is wide to be 5cm, also is provided with pitch hemp cut layer or waterproofing course in the shrinkage joint 14.
Every joint roadbed unit comprises pile plate foundation 10, roadbed wall 13, pallet 14 and sidewalk 19.Pile plate foundation 10 specifically comprises loaded plate 12 and many foundation stake 11, and loaded plate 12 is located at many foundation stake 11 tops and is the integral type structure with many foundation stake 11, and the bottom surface of loaded plate 12 generally is positioned at below the Z-Z of ground.Particularly, foundation pile 11 adopts the above deposited reinforced concrete pile of C30, and the diameter of foundation pile 11 is more than or equal to 1m, and the spacing L of adjacent two pile bases 11 is generally greater than 3m, and the length that the top of foundation pile 11 is stretched in the loaded plate 12 is 0.5 ~ 1m.Loaded plate 12 adopts the above steel concrete of C30 to build.
Roadbed wall 13 is fixed on the loaded plate 12, and pallet 14 is fixed on the roadbed wall 13, and the end face of pallet 14 is provided with gear tiny fragments of stone, coal, etc. groove 15.The bottom surface of gear tiny fragments of stone, coal, etc. groove 15 is arranged with weathering 16, and the gradient of weathering 16 is 4%.Pallet 14 both sides are provided with the spilled water hole 17 of a plurality of lateral direction penetratings, and the distance between adjacent two spilled water holes 17 is 5 ~ 10m, and are provided with the PVC gutter in the spilled water hole 17.In addition, be provided with successively waterproofing course (not shown), topping (not shown) and railway ballast layer 18 in the gear tiny fragments of stone, coal, etc. groove 15.Particularly, roadbed wall 13 adopts the above plain concrete of C30 or slabstone concreting.Pallet 14 adopts the above steel concrete of C30 to build, and base plate thickness is 0.3 ~ 0.6m, highly exceeds tiny fragments of stone, coal, etc. pin 0.3m.
