Abstract
A combined structure for an abrupt slope road bed of a rapid transit railway is characterized by being strong in integrity, good in stability, firm and durable and favorable for high speed vehicle running. The combined structure comprises reinforced concrete piles (10), L-shaped reinforced concrete structures (20) and road bed filling bodies (30), wherein the reinforced concrete piles (10) are horizontally arranged in two rows along the road bed and longitudinally arranged at intervals along the road bed, the L-shaped reinforced concrete structures (20) extend along the road direction and are arranged on pile tops of the reinforced concrete piles (10) to be fixedly connected with the reinforced concrete piles (10), and the road bed filling bodies (30) are filled on the inner side of the L-shaped reinforced concrete structures (20). The combined structure for the abrupt slope road bed of the rapid transit railway has the advantages of being strong in integrity, good in stability, firm, durable, small in rail deformation and the like, favorable for high speed vehicle running, and capable of greatly reducing maintenance work amount. Construction technology is simple, can effectively reduce building cost, meets environment protection requirements and has wide application and popularization prospects.
Description
Technical field
The present invention relates generally to the structure of abrupt slope roadbeds such as railway, highway; Being particularly related to the mountain area gradient slope and the face of land has thicker distribution soil layer, avoids occurring roadbed the high-speed railway abrupt slope roadbed combining structure structure that bottom retaining structure horizontal distortion is big, abrupt slope roadbed soil layer settling amount is handled constructional difficulties than big and employing composite foundation is set.
Background technology
At present, China's mountain area advanced road begins to build in a large number, and the abrupt slope roadbed is more and more.High-speed railway has all proposed new requirement to high ride, stability, the durability of circuit, and satisfy the need base base total settlement, settlement after construction and relative settlement amount all have strict restriction.
There is following problem in traditional abrupt slope road structure, and the abrupt slope roadbed is provided with roadbed bottom retaining structure, because bottom retaining structure horizontal distortion is bigger, the long length of stake often need be set could satisfies the high-speed railway requirement with the bigger reinforced concrete pile in stake cross section; Roadbed top layer, abrupt slope soil layer is not handled settling amount than the heavy back base and is very much not satisfied the high-speed railway requirement, carries out the composite foundation processing and is difficult to construction, and have the horizontal differential settlement of roadbed; If adopting bridge construction one is that excavation abutment excavation slope is higher, the 2nd, cost is too high.
Therefore, a kind of intensity of active demand is high, rigidity is big, stability and good endurance and the simple new construction roadbed of construction technology, and meets environmental protection requirement.
Summary of the invention
Technical problem to be solved by this invention provides a kind of high-speed railway abrupt slope roadbed combining structure structure, has that globality is strong, a good stability, robust characteristics, and helps high speed traveling.
The technical solution adopted for the present invention to solve the technical problems is following: roadbed combining structure structure in high-speed railway of the present invention abrupt slope is characterized in that it comprises: reinforced concrete pile along roadbed lateral arrangement two rows, is provided with along roadbed longitudinal separation; L shaped steel tendon concrete structure, road along the line direction is extended, and places each reinforced concrete pile stake top and fixed with it; The roadbed filling body fills in L shaped steel tendon concrete structure inboard.
In technique scheme, be provided with the rubble loaded filter between said L shaped steel tendon concrete structure cantilever inboard and roadbed filling body, said L shaped steel tendon concrete structure cantilever side bottom and metope are provided with spilled water hole at interval.
The invention has the beneficial effects as follows, strong, the good stability, sturdy and durable of this roadbed combining structure globality, track deformation is little, and advantage such as accumulated deformation is little, helps high speed traveling, can reduce the maintenance workload greatly; Construction technology is simple, can effectively reducing the construction costs, and compliance with environmental protection requirements, have wide popularizing application prospect.
Description of drawings
This manual comprises following two width of cloth accompanying drawings:
Fig. 1 is the schematic cross-sectional view of high-speed railway of the present invention abrupt slope roadbed combining structure structure;
Fig. 2 is the front schematic view of high-speed railway of the present invention abrupt slope roadbed combining structure structure;
Member shown in the figure, toponym and pairing mark: reinforced concrete pile 10, L shaped steel tendon concrete structure 20, shrinkage joint 21, spilled water hole 22, roadbed filling body 30, rubble loaded filter 31.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is further specified.
With reference to Fig. 1, roadbed combining structure structure in high-speed railway of the present invention abrupt slope comprises: reinforced concrete pile 10 along roadbed lateral arrangement two rows, is provided with along roadbed longitudinal separation; L shaped steel tendon concrete structure 20, road along the line direction is extended, and places 10 tops and fixed with it of each reinforced concrete pile; Roadbed filling body 30 fills in L shaped steel tendon concrete structure 20 inboards.With reference to Fig. 2, said L shaped steel tendon concrete structure 20 cantilevers are inboard to be provided with rubble loaded filter 31 with roadbed filling body 30; Said L shaped steel tendon concrete structure 20 cantilever side bottoms and metope are provided with spilled water hole 22 at interval.
After taking technique scheme; Reinforced concrete pile 10 is rigidly connected with L shaped steel tendon concrete structure 20 and makes that this structural integrity is strong; Bear through reinforced concrete pile 10 that banket in top and train load; Utilizing L shaped steel tendon concrete structure 20 to solve the vertical sedimentation of roadbed satisfies the high speed traveling requirement and reduces the combining structure cantilever height with horizontal uneven subsidence; Utilize outside reinforced concrete pile 10 to reduce the bending moment that this combining structure external force effect forms, utilize backer's side reinforced concrete pile 10 to increase this combining structure opposing external force bending moment effect.
With reference to Fig. 2, usually, the thickness of said rubble loaded filter 31 is 0.3m, and said spilled water hole 22 is 2～3m, is the blossom type laying that by spacing the aperture is Φ 50mm.With reference to Fig. 1, said L shaped steel tendon concrete structure 20 every interval 15～20m are provided with shrinkage joint, a place 21 between vertical adjacent steel rib concrete pile 10, adopt the filling of pitch plank in the shrinkage joint 21.The vertical main reinforcement of said reinforced concrete pile 10 need stretch in the L shaped steel tendon concrete structure 20 and be attached thereto into an integral body.
Some principles of the above high-speed railway of the present invention abrupt slope roadbed combining structure structure that just explains through diagrams; Be not be to the present invention be confined to shown in described concrete structure and the scope of application in; So every the modify and equivalent that might be utilized, the claim that all belongs to the present invention and applied for.
