Description
Technical field
The present invention relates to a kind of high-fill roadbed guard system and its construction methods, belong to urban municipal road technology neck
Domain.
Background technique
The subgrade protection of high roadbed road can be divided into two classes according to supporting and retaining system mode: (1) rectilinear supporting and retaining system, as retaining wall,
It paddles revetment etc.；(2) ramp type supporting and retaining system, such as plant slope protection, engineering slope protection.Since rectilinear supporting and retaining system cost is high, applies
Work difficulty is big, for usefully condition outside road, generally uses ramp type supporting and retaining system.
Ramp type supporting and retaining system is banketed using the ramp system of slope ratio 1:1 to 1:2 that is, on the outside of the roadbed of road, utilizes slope
The soil body protects roadbed.To slow down slope soil by rain drop erosion, slope soil surface generally uses plant protection or engineering anti-
Shield.Slope plants protection is exactly to plant trees in ramped surfaces kind grass, or plant careless plant again after ramped surfaces are first laid with hollow concrete block
Tree；Slope engineering protection is exactly or in ramped surfaces dry-laid rubble or to grout in ramped surfaces sandblasting slurry or joints cement concrete
Slabstone.
Slope surface is disadvantageous in that using engineering protection: (1) engineering protection cost is high, difficulty of construction is big, the slope surface soil body
Completely cut off completely with extraneous contacting by hard material, not only landscape effect is poor, and does not utilize and improve the ecological environment；(2) road
Inside configuration water cannot exclude, and lower seep to soil matrix influences slope stability.Slope surface is disadvantageous in that using plant protection: (1)
When rainfall is big, rainwater on road surface converges into slope surface, and slope surface is be easy to cause coombe occur, destroys slope vegetation, influences subgrade stability；
(2) road structure internal water cannot exclude, and lower seep to soil matrix influences slope stability.
Summary of the invention
The purpose of the present invention is to solve the above problems, provide a kind of simple high-fill roadbed protection of construction method
System and its construction method.
The present invention adopts the following technical scheme: a kind of high-fill roadbed guard system, including beside roadbed gutter,

Further, cover board ditch is to collect and exclude rainwater on road surface, and french drain is to collect and exclude inside configuration water.
Further, cover board ditch and french drain are mutually independent drainage system.
The construction method of high-fill roadbed guard system, includes the following steps:
(1) anti-after the completion of subgrade construction to excavate soil matrix, construction drainage ditch basis and french drain (1-2), the second drainpipe (3), row
Ditch basis is close to roadbed and is poured, and gutter (1) includes cover board ditch (1-1) and french drain (1-2), and french drain (1-2) setting exists
The lower section of cover board ditch (1-1), french drain (1-2), which is that non-sand concrete is cast-in-place, to be made；Connect the second drainpipe (3) and blind pipe, the second draining
Managing (3), laying, the gradient are not less than 2% from high to low；The spacing of second drainpipe (3) is 30 ~ 50m, and the cover board of the cover board ditch is
Steel fibre concrete is prefabricated；
(2) after the completion of the last stage, construct road surface, after the completion of pavement construction, soil matrix on the outside of construction drainage ditch；
(3) construction drainage ditch two sides rubble, and then construct cover board ditch (1-1) and the first drainpipe (2), the cover board ditch (1-
1) setting is on road shoulder surface, and the ditch body of cover board ditch (1-1), which is that C20 reinforced concrete is cast-in-place, to be made, and the first drainpipe (2) applies from high to low
If, the gradient be not less than 2%；First drainpipe (2) and the second drainpipe (3) correspond, and arrange in center vertical alignment；
(4) backfill gutter two sides are native and are compacted, and modify road shoulder, are arranged step (4)；
(5) road slope, gutter are modified, step used for overhaul of constructing in the side slope by gutter makes the side of side slope bottom
Ditch (5) is connected with river along the line；
(6) grass is planted at road shoulder and side slope to plant trees, form vegetable layer.
Construction method of the present invention is simple, after subgrade protection system is built up, can exclude in rainwater on road surface and road structure
Portion's water, but can slow down rainwater side slope wash away and destruction of the inside configuration water to roadbed, improve existing work in the present invention
The deficiency that journey protects that cost is high, landscape effect is poor, is unfavorable for ecology etc., but it is easy by rain drop erosion to improve existing plant protection
Deng deficiency, also improve existing slope protection system.
