Abstract
A kind of High Speed Railway Subgrade by karst sinkhole, can effectively discharge surface water, sinkhole is not blocked, meets the requirement of high-speed railway subgrade, and it is easy for construction.It includes：Rotary churning pile, it is arranged in the earthen foundation on sinkhole periphery, forms occlusion and enclose curtain structure；Reinforcing pile, it is arranged in the earthen foundation outside sinkhole scope；Drainage frame, is arranged at the top of the ground of sinkhole coverage, and roadbed filling body is filled at the top of drainage frame.
Description
Technical field
Geotechnical Engineering is the utility model is related to, more particularly to passes through the high-speed railway subgrade engineering of karst sinkhole.
Background technology
Sinkhole is the common surface water drain passage in karst landform area, and normal conditions are unable to silting, otherwise can influenceed
The excretion of surface water, or even produce floods.When railway can only in the form of roadbed by when, how to accomplish not block sinkhole, again
The requirement of high-speed railway subgrade can be met, just seem increasingly important.It is therefore proposed that a kind of high-speed railway by karst sinkhole
Road structure is significant.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of high-speed railway subgrade knot by karst sinkhole
Structure, can effectively discharge surface water, sinkhole is not blocked, meets the requirement of high-speed railway subgrade, and it is easy for construction.
Technical scheme is as follows used by the utility model solves above technical problem：
A kind of High Speed Railway Subgrade by karst sinkhole of the present utility model, it is characterized in that it includes：Churning
Stake, is arranged in the earthen foundation on sinkhole periphery, forms occlusion and encloses curtain structure；Reinforcing pile, it is arranged on outside sinkhole scope
Earthen foundation in；Drainage frame, is arranged at the top of the ground of sinkhole coverage, and roadbed filling body is filled in drainage frame
Top.
The beneficial effects of the utility model are that solve sinkhole draining and roadbed filling meets the difficulty of high-speed railway requirement
Topic, and have the characteristics that easy for construction, economical and environmentally friendly, there is popularizing application prospect.
Brief description of the drawings
This specification includes following three width accompanying drawing：
Fig. 1 is a kind of sectional schematic diagram of High Speed Railway Subgrade by karst sinkhole of the utility model.
Fig. 2 is a kind of floor map of High Speed Railway Subgrade by karst sinkhole of the utility model.
Fig. 3 is a kind of drainage frame front signal of High Speed Railway Subgrade by karst sinkhole of the utility model
Figure.
Component name and corresponding mark are shown in figure：Rotary churning pile 1, reinforcing pile 2, drainage frame 3, bottom plate 31, side wall
32nd, top plate 33, osculum 34, roadbed filling body 4, sinkhole A, earthen foundation B, rock quality base C.
Embodiment
The utility model is further illustrated with reference to the accompanying drawings and examples：
Reference picture 1, Fig. 2, a kind of High Speed Railway Subgrade by karst sinkhole of the present utility model include：Churning
Stake 1, is arranged in the earthen foundation B on sinkhole A peripheries, forms occlusion and encloses curtain structure；Reinforcing pile 2, it is arranged on sinkhole A scopes
Outside earthen foundation B in；Drainage frame 3, is arranged at the top of the ground of sinkhole A coverages, and roadbed filling body 4 fills
The top of drainage frame 3.
Occlusion is formed in the earthen foundation B on sinkhole A peripheries with rotary churning pile 1 and enclose curtain, avoid sinkhole A bands in draining
The soil property around hole is walked, so as to ensure the stability of earthen foundation.The reinforcing pile 2 being arranged in earthen foundation B solves high-speed iron
The problem of road settlement of foundation, and higher bearing capacity is provided for drainage frame 3, increase the stability of drainage frame 3.With draining frame
Drainage channel of the frame 3 as surface water and sinkhole A, ensures the stabilization of roadbed, and as the bearing structure of roadbed filling body 4,
Bearing structure of the roadbed filling body 4 as train load.The beneficial effect of the structure is that solve sinkhole draining and roadbed is filled out
The problem for meeting high-speed railway requirement is built, and has the characteristics that easy for construction, economical and environmentally friendly, there is popularizing application prospect.
Reference picture 1, rotary churning pile 1 a diameter of 0.8m, the spacing 0.6m, processing depth to rock quality base C bedrock surfaces.It is described
Reinforcing pile 2 is using CFG (CFG stakes) or compaction thread etc., and stake spacing is usually 1.5-1.8m, and processing is deep
Spend to rock quality base C bedrock surfaces.
Reference picture 3, the drainage frame 3 are poured using armored concrete, and it is pre- in the position of bottom plate 31 corresponding to sinkhole A
Osculum 34 is stayed, width is set not less than twice of sinkhole A diameters.The size of osculum 34 is not less than chi of the sinkhole on ground
It is very little.
The utility model a kind of High Speed Railway Subgrade by karst sinkhole 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.
