Abstract
The utility model discloses a silty soil section highway drainage system, comprising a hardened earth shoulder, a water collection side ditch, a slope, a berm and a gutter which are sequentially arranged at the side of a highway, wherein the slope is provided with a sunken chute by which the pavement is communicated with the gutter. According to the silty soil section highway drainage system disclosed by the utility model, at a silty soil section with the filling height being not less than 3m, a chute is arranged at each lowest point of the concave curve of the highway, and chutes are also arranged at an interval of 30m between two adjacent lowest points of the concave curve of the highway, so that rainwater on the highway is rapidly converged into the gutter through the chutes, thus reducing scouring of rainwater to side slopes of highways and improving the stability of the side slopes of the silty soil section.
Description
Technical field
The utility model relates to road slope drainage works field, is specifically related to silt highway section road drainage system.
Background technology
Soil property is mainly based on the area of silt, and the cohesive force of soil is lower, and slope of highway is subjected to rain drop erosion easily, high embankment highway section particularly, and rain drop erosion produces greatly influence for the stability of side slope.Stable for strengthening roadbed side slope, prevent that side slope is caved in by rain drop erosion, for the highway section of roadbed raising 〉=3.0m, the protection form that adopts is the protection of hexagon hollow piece grass planting usually.In actual use, find that the compacting of the common roadbed side slope soil body is not enough, vegetation is difficult for survival in the hexagon hollow piece.Therefore interim in rainy season, the soil in the hexagon hollow piece still can be caused problems such as emptying appears in side slope, depression, soil erosion by rain drop erosion.
In the face of above problem, except improving the construction technology quality, select for use outside the easy survival vegetation in the roadbed side slope construction, also should strengthen the further investigation to the roadbed slope drainage.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of silt highway section road drainage system, suits measures to local conditions, and adopts comparatively directly drainage smoothly, and the minimizing rainwater washes away for roadbed side slope, keeps the stable of silt highway section side slope.
The utility model is achieved through the following technical solutions:
Silt highway section road drainage system comprises the gutter of the domatic and domatic oblique below that is positioned at the road surface side, the described domatic chute that is provided with depression, and chute is communicated with road surface and gutter.
The further improvement project of the utility model is that described chute trend is vertical with the road surface direction, linearly arranges.
The utility model further improvement project is that described chute is made up of the sand cushion of bottom and the cement concrete layer on upper strata.
The utility model further improvement project is that described chute is arranged at each lowest point of highway sag vertical curve.
The utility model further improvement project is that a chute is set every about 30 meters between each lowest point of described highway sag vertical curve.
The utility model further improvement project is, described road surface side is provided with earth shoulder, and described earth shoulder is provided with the gutter that catchments near a domatic side.
The utility model further improvement project is, described earth shoulder and domatic between be provided with the gutter that catchments.
The utility model further improvement project is, is provided with banket between the described domatic and gutter.
The utility model compared with prior art has following obvious advantage:
One, the utility model is collected the road surface rainwater fast and effectively, by catchment gutter and chute rainwater is imported gutter, has reduced rainwater to the washing away of side slope, and has improved the stability of silt highway section side slope.
Two, with the contrast of PVC gutter: the utility model adopts the gutter drainage form, the draining smoothness, and silt or rubbish remaining in the chute are easy to the cleaning mediation.And pvc pipe interface sealing is poor, seepage takes place during heavy rain, and silt up easily.

Fig. 2 is the I-I cross-sectional drawing of Fig. 1.
Fig. 3 is the chute profile.
The specific embodiment
As shown in Figure 1 to Figure 3, drainage system described in the utility model, comprise the earth shoulder 2 that is positioned at road surface 1 side successively, the gutter 3 that catchments, domatic 4, banket 5, gutter 6, described domatic 4 are provided with the chute 7 of depression, and chute 7 is communicated with road surfaces 1 and gutters 6.Described chute 7 trends are vertical with road surface 1 direction, linearly arrange.Described chute 7 is made up of with the cement concrete layer 72 on upper strata the sand cushion 71 of bottom.
Present embodiment is in the silt highway section of raising 〉=3m, is provided with chute 7 in conjunction with each lowest point of highway sag vertical curve, and a chute is set every about 30 meters between each lowest point of described highway sag vertical curve again.Make the road surface rainwater import gutter fast by chute, reduce rainwater washing away slope of highway.
For improving the rainwater collection rate, prevent that rainwater from oozing by under the earth shoulder, be provided with the gutter 3 that catchments at earth shoulder 2 near domatic 4 one sides, the water in the gutter 3 that catchments imports in the side slope chute 7 every about 30m.
