Abstract
The invention provides a widening reinforcing structure tightly adjacent to an existing ballastless track roadbed. The influences of stress and deformation on an existing ballastless track railway roadbed body and a base due to a widening roadbed filling load and a train load are effectively eliminated, and meanwhile the problems about the foundation bearing capacity and settlement of a newly-built widening roadbed are solved. The widening reinforcing structure comprises the existing ballastless track roadbed and a newly-built widening filling roadbed located on one side of the ballastless track roadbed in the transverse direction. The newly-built widening filling roadbed comprises a reinforced concrete tray type retaining wall, reinforced concrete pile foundations and a foam light soil filling layer. The reinforced concrete tray type retaining wall is located on one side of the existing ballastless track roadbed in the transverse direction and extends in the direction of a line. The reinforced concrete pile foundations are arranged in a foundation of the newly-built widening filling roadbed in rows at intervals in the direction of the line, and the upper ends of the reinforced concrete pile foundations are in rigid connection with the reinforced concrete tray type retaining wall. The foam light soil filling layer is built above the reinforced concrete tray type retaining wall in a filled manner.
Description
Technical field
The present invention relates to railway bed, be close to the wide reinforcing construction of existing ballastless track roadbed side particularly to one.
Background technology
Railway, highway construction process in, particularly during railway construction, need integrate with in existing high ferro or help wide situation the most, the filler load of side wide portion and train load will make existing non-fragment orbit produce settlement after construction, owing to high speed non-fragment orbit railway is the highest to settlement request, and there is fastener adjustment amount deficiency or the problem of storage level loss, simultaneously the most wired operation limitation carries out stiffening basic ground under the most wired, is therefore badly in need of a kind of novel structure and solves this type of difficult problem.
Summary of the invention
The technical problem to be solved is to provide the wide reinforcing construction of a kind of next-door neighbour existing ballastless track roadbed side, with effective side broad way based filler load and train load of solving, existing non-fragment orbit railway bed body and substrate are produced stress, the impact of deformation, solve foundation bearing capacity and the settlement issues of newly-built side broad way base simultaneously.
It is as follows that the present invention solves the technical scheme that this technical problem used:
The wide reinforcing construction of next-door neighbour's existing ballastless track roadbed side of the present invention, fill out roadbed including existing ballastless track roadbed with the newly-built side being positioned at its horizontal side, it is characterized in that: described newly-built side fills out roadbed and includes armored concrete pellet type barricade, steel bar concrete pile plinth and Foam lightweight soil packing layer；Described armored concrete pellet type barricade is positioned at the horizontal side of existing ballastless track roadbed, extends along line direction；Described steel bar concrete pile plinth is in a row arranged in the ground that roadbed is filled out by newly-built side along line direction interval, and its upper end is rigidly connected with armored concrete pellet type barricade；Described light soil packing layer fills on armored concrete pellet type barricade.
The invention has the beneficial effects as follows, broadly section is helped for being close to existing non-fragment orbit railway bed, side broad way based filler load and train load can be solved existing non-fragment orbit railway bed body and substrate are produced stress, the impact of deformation, foundation bearing capacity and the settlement issues of newly-built side broad way base can be solved simultaneously, structure stress is simply clear and definite, and working security is high, and globality is strong, good stability, has broad application prospects.
Accompanying drawing explanation
This specification includes following three width accompanying drawings:
Fig. 1 is the cross-sectional view that the present invention is close to the wide reinforcing construction of existing ballastless track roadbed side；
Fig. 2 is the front elevation that the present invention is close to the wide reinforcing construction of existing ballastless track roadbed side；
Fig. 3 is the plane graph that the present invention is close to the wide reinforcing construction of existing ballastless track roadbed side.
Component shown in figure, toponym and corresponding labelling: existing ballastless track roadbed A, roadbed B, armored concrete pellet type barricade 1, steel bar concrete pile plinth 2, Foam lightweight soil packing layer 3 are filled out by newly-built side.
Detailed description of the invention
With embodiment, the invention of this reality is further illustrated below in conjunction with the accompanying drawings.
With reference to Fig. 1, Fig. 2 and Fig. 3, the wide reinforcing construction of next-door neighbour's existing ballastless track roadbed side of the present invention, fill out roadbed B including existing ballastless track roadbed A and the newly-built side being positioned at its horizontal side.Described newly-built side fills out roadbed B and includes armored concrete pellet type barricade 1, steel bar concrete pile plinth 2 and Foam lightweight soil packing layer 3.Described armored concrete pellet type barricade 1 is positioned at the existing horizontal side of ballastless track roadbed A, extends along line direction.Described steel bar concrete pile plinth 2 is in a row arranged in the ground that roadbed B fills out in newly-built side along line direction interval, and its upper end is connected surely with armored concrete pellet type barricade 1 rigidity.Described light soil packing layer 3 fills on armored concrete pellet type barricade 1.
The power that roadbed filling and train load produce is transformed on lower rebar concrete pile foundation 2 by armored concrete pellet type barricade 1.Power on armored concrete pellet type barricade 1 and moment of flexure are delivered in the foundation soil of newly-built side broad way base bottom by steel bar concrete pile plinth 2, reduce the stress to existing non-fragment orbit railway bed, deformation effect, play stability problem and the effect of stability against slope problem solving armored concrete pellet type barricade 1, solve bearing capacity and the settlement issues of newly-built side broad way base base simultaneously.Light soil packing layer 3 can use Foam lightweight soil filler to fill, and reduces the impact that weight load produces.
With reference to Fig. 2, described armored concrete pellet type barricade 1 is arranged along line direction framing, to cut off the stress of armored concrete pellet type barricade 1.
The above present invention that simply explains through diagrams is close to some principles of the wide reinforcing construction of existing ballastless track roadbed side, it is not intended to be confined to by type of the present invention in shown and described concrete structure and the scope of application, therefore every corresponding amendment being likely utilized and equivalent, belong to the apllied the scope of the claims of the present invention.
