Description
Technical field
The utility model is related to railway engineerings, more particularly to a kind of non-fragment orbit high-speed railway subgrade face waterproof/drainage structure.
Background technology
High-speed railway especially non-fragment orbit high-speed railway needs to ensure road structure since it requires basic freedom from repairs
Long-time stability and durability, to need to reinforce the waterproof and drain measure of road bed, especially Frozen Ground Area, if surface water
Into frost-heaving deformation can occur in road structure.Traditional ballastless track roadbed usually uses bituminous concrete or fibre in road bed
It ties up concrete and carries out roadbed face closure, but under the action of the train dynamic stress repeatedly of top, track infrastructure and construction in later period
Water-protected enclosure layer be inevitably generated crack, cause surface water to enter in road structure body, currently without preferable measure
It can accomplish long-term effective guarded drainage, therefore be badly in need of a kind of non-fragment orbit high-speed railway subgrade face waterproof/drainage structure, and should have warp
The features such as helping, be easy for construction, safe and environment-friendly.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of non-fragment orbit high-speed railway subgrade face guarded drainage knots
Structure avoids roadbed from water damage occur to ensure that road bed guarded drainage performance is permanently effective.
Technical solution is as follows used by the utility model solves above-mentioned technical problem：
A kind of non-fragment orbit high-speed railway subgrade face waterproof/drainage structure of the utility model, including placement in layers is under roadbed
The roadbed surface structure of portion's structural top, track supporting layer are arranged at the top of roadbed surface structure, roadbed surface structure lateral two
Cable trough and shoulder protector is arranged in side, it is characterized in that：The both lateral sides of the roadbed surface structure are to sink relative to what its top surface sank
Slot structure, the side wall laying water-proof coiled material along roadbed surface structure surface to track supporting layer, waterproof roll and track supporting layer
The reserved baltimore groove of side wall is seamless bonding, and fiber concrete layer is poured on the waterproof roll at top；It is heavy that the cable trough is set to
The inside of slot structure, shoulder protector are set to the outside of cable trough and deep gouge structure.
The beneficial effects of the utility model are mainly reflected in following several respects：
One, waterproof roll is laid with to track supporting layer side wall, and the baltimore groove reserved with its side wall is seamless bonding, waterproof volume
Not to exposing outside and being higher than surface water depth of accumulated water, table water cannot enter lower part road structure and neutralize the road to connect with cable trough material
In based structures, and appearance forrns are good；
Two, waterproof roll is laid with using composite geotextile material seamless welding, can be supported to avoid track for flexible structure
Layer deforms uncoordinated problem under dynamic stress effect, can be for a long time seamless bonding with track supporting layer；
Three, fiber concrete layer is arranged at the top of waterproof roll, makes waterproof roll that there is better durability, top to set
It is set to the drainage grade not less than 0.5%, is conducive to surface water and excludes faster；
Four, the inside and bottom of cable trough 5, which are provided with waterproof roll 3, will not enter roadbed to avoid the water in cable trough
In structure；
Five, the structure efficiently solves the technical barrier of the long-term guarded drainage in non-fragment orbit high-speed railway subgrade face, has and applies
The features such as work is simple, construction investment is low has popularizing application prospect, and meets the requirement of environmental protection.
