Preferably, being provided with the second metalling between the wall back of the body and Stone Filled Embankment of the inclined retaining wall, metalling is by small The compacting of particle diameter stone grain forms, and does not influence that permeable while consistency is high, increases the stable degree of roadbed.
Preferably, the bottom of the canal that drains off floodwaters is provided with the 3rd metalling, intensity is improved.
Preferably, building stones particle diameter is 20cm ~ 40cm in the Stone Filled Embankment.
Preferably, the side that discharge structure is not provided with the Stone Filled Embankment both sides is externally provided with gutter, for arranging Go out a small amount of surface water.
Preferably, the embankment is divided into the transition between upper strata, lower floor, the upper and lower according to slope gradient difference Layer, the slope gradient on the upper strata is 1:1.5, the slope gradient of the lower floor is 1:1.75, the structure makes overall roadbed reclamation Property it is high.
Compared with prior art, the utility model has the advantages that:A kind of mountain valley high roadbed is provided to rockfill road Dike discharge structure, former surface drainage is effectively maintained by Stone Filled Embankment, ensure that the road circle draining after roadbed filling is unimpeded, Reduce influence of the operation phase surface water to embankment stability;Simple in construction, technical maturity simultaneously, construction is quick and convenient, and has Reduce construction cost to effect.
Brief description of the drawings
Fig. 1 is the diagrammatic cross-section of the embankment and discharge structure in the utility model.
Fig. 2 is the enlarged diagram of a-quadrant in this Fig. 1.
Embodiment
The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings.
Reference picture 1 and Fig. 2, a kind of mountain valley high roadbed Stone Filled Embankment discharge structure, the discharge structure include being used as under embankment The Stone Filled Embankment 1 in portion and the inclined retaining wall 4 located at the outside of Stone Filled Embankment 1, several spilled water holes are provided with the inclined retaining wall 4 5, the outside of inclined retaining wall 4 is provided with the canal 7 that drains off floodwaters
Embankment in present embodiment, including the high-filled embankment 9 on the Stone Filled Embankment 1 of bottom and top, wherein, road of rockfilling Building stones particle diameter is 20cm ~ 40cm in dike 1, and anti-filter separation layer, anti-filter isolation are provided between Stone Filled Embankment 1 and high-filled embankment 9 Layer includes the first metalling 2 and the non-woven geotextile 3 being covered on the first metalling 2.In addition, in present embodiment, it is described to face upward The second metalling 6 is provided between the wall back of the body and Stone Filled Embankment 1 of inclined barricade 4, the bottom of the canal 7 that drains off floodwaters is provided with the 3rd metalling 8。
In present embodiment, the side that discharge structure is not provided with the both sides of Stone Filled Embankment 1 is externally provided with gutter 10, embankment Transition zone between upper strata, lower floor, the upper and lower is divided into according to slope gradient difference, the slope gradient on the upper strata is 1: 1.5, the slope gradient of the lower floor is 1:1.75, subgrade stability is high.
When mountain valley high roadbed Stone Filled Embankment discharge structure in the utility model is built, the upper and lower, upper strata are first determined Filled using the earthwork (soil-stone material), slope gradient 1:1.5, lower floor gathers materials on the spot, using Stone Filled Embankment as top drainage Pervious bed, slope gradient 1:1.75, and inclined retaining wall 4 and the combining structure of canal 7 of drainning off floodwaters are set.Wherein, building stones in Stone Filled Embankment 1 Size controlling is 20cm ~ 40cm, and placement in layers, the enhancing ftercompction of top surface strong rammer, construction speed is fast, and drainage performance is good, subgrade stability It is good.
