Description
Technical field
The utility model is related to embankment structures, are specifically that a kind of fine grained soil of superelevation embankment fills structure.
Background technology
In road construction, when newly-built road intersects with coombe, it is necessary to carry out embankment.Practice have shown that it passes
The embankment structure of system is since self structure is limited, and there are the following problems：First, in traditional embankment structure, by
It is blocked up in banketing for ditch heart culvert top, cause the structural instability and impeded drainage of ditch heart culvert, thus constrain roadbed and fill out
The feasibility built.Second, in traditional embankment structure, since ditch heart charge for remittance is to the immersion emollescence of road ground,
Road ground is caused easily to settle, thus equally constrains the feasibility of roadbed filling.Third, applied to mountain road
When, traditional embankment structure can not digest the waste for closing on excavation, cause its is long in time limit, cost is high, not environmentally.It is based on
This, it is necessary to a kind of brand-new embankment structure is invented, causes the knot of ditch heart culvert to solve traditional embankment structure
Structure is unstable and impeded drainage, causes road ground that sedimentation easily occurs, can not be digested when applied to mountain road and close on digging
The problem of waste of side.
The content of the invention
The utility model in order to solve traditional embankment structure cause ditch heart culvert structural instability and draining not
Freely, the problem of causing road ground that sedimentation easily occurs, can not digest the waste for closing on excavation when applied to mountain road, carry
A kind of fine grained soil of superelevation embankment has been supplied to fill structure.
The utility model adopts the following technical scheme that realization：
A kind of fine grained soil of superelevation embankment fills structure, including coombe, embankment；Wherein, the ditch heart of coombe is provided with ground
Reinforcing layer and slabstone french drain；Slabstone french drain is consistent with coombe direction；The embankment slope foot of coombe upstream side has filled width and has filled out fine grained soil
Platform；The slope surface that width fills out fine grained soil platform is provided with mortar rubble masonry pavement；The top surface that width fills out fine grained soil platform is provided with concrete
Gutter；The slope surface that the upstream end in concrete gutter fills out fine grained soil platform with width flushes；The downstream in concrete gutter connects
It is connected to Steel Corrugated Pipe Culvert；Steel Corrugated Pipe Culvert runs through embankment, and the downstream of Steel Corrugated Pipe Culvert is connected with chute；Under chute
Trip end extends to the ditch heart of coombe.
Specifically used process is as follows：When rainfall occurs, wide fine grained soil platform of filling out obstructs ditch heart charge for remittance so that ditch
The water level of heart charge for remittance is gradually increasing.When the water level of ditch heart charge for remittance, which rises to width, fills out the apical side height of fine grained soil platform, Gou Xinhui
Water passes sequentially through concrete gutter, Steel Corrugated Pipe Culvert, chute are drained to coombe.In the process, small part ditch heart charge for remittance
It can be discharged by slabstone french drain after penetrating into foundation stabilization layer.Based on the above process, compared with traditional embankment structure, sheet
A kind of fine grained soil of superelevation embankment described in utility model fills structure by the way that width is set to fill out fine grained soil platform, on the one hand reduces
Ditch heart culvert（That is Steel Corrugated Pipe Culvert）On the other hand it is soft to the immersion of road ground to have separated ditch heart charge for remittance for the filled slope on top
Change acts on, and the third aspect has digested the waste for closing on excavation, thus on the one hand ensure that stable structure and the draining of ditch heart culvert
It is unimpeded, it on the other hand avoids road ground and settles, the third aspect shortens the duration, has saved cost, realized environmental protection,
So as to ensure that the feasibility of roadbed filling.
The utility model is rational in infrastructure, ingenious in design, and efficiently solving traditional embankment structure causes ditch heart culvert
Structural instability and impeded drainage, cause road ground easily occur sedimentation, can not digest and face when applied to mountain road
The problem of waste of nearly excavation, suitable for road construction.
