Abstract
The utility model discloses a kind of roadbed filling structures in the precipitous section in mountain area, and including the roadbed being arranged close to massif side and the road surface structare layer being set on roadbed, the roadbed is light foam concrete structure sheaf.The utility model has the characteristics that load is small, stability is high, difficulty of construction is low, it is small to be not take up extra soil, environmental cost, can be widely applied to road and bridge construction field.
Description
Technical field
The utility model relates to road and bridge construction fields, more particularly to a kind of roadbed filling structure in the precipitous section in mountain area.
Background technique
The engineering construction in the precipitous section in mountain area is always the difficult point in road and bridge construction field, and traditional construction method mainly includes
Two kinds: one, conventional embankment formula barricade engineering method has built road surface knot at the top of fill subgrade 9 and outside referring specifically to Fig. 1 respectively
Structure layer 2 and embankment formula barricade 10,10 section of embankment formula barricade are in up-small and down-big trapezium structure, and the shortcomings that this structure is
Stability is difficult to guarantee, and supporting cost is high, long in time limit.Two, engineering method is dug in conventional high raising, referring specifically to Fig. 2, the material of fill subgrade 9
Material arises directly from the earthwork 11 of upper layer massif 1, then the fill subgrade 9 is built on fill subgrade 9 again along 1 slope of massif
Road surface structare layer 2 is built, the deficiency of this structure is that high raising is dug, and supporting cost is high, big to environmental disruption.It is possible thereby to see
Out, in traditional engineering method fill subgrade 9 due to the load of itself it is big, lead to that slip moment is big, stability is poor, and difficulty of construction
Height, a large amount of land occupation resources are larger to environment bring destructiveness.
Utility model content
The purpose of this utility model is to overcome the deficiencies of above-mentioned background technique, provide a kind of road in precipitous section in mountain area
Base fills structure, makes it have that load is small, stability is high, difficulty of construction is low, is not take up the small spy of extra soil, environmental cost
Point.
The roadbed filling structure in the precipitous section in a kind of mountain area provided by the utility model, including what is be arranged close to massif side
Roadbed and the road surface structare layer being set on roadbed, the roadbed are light foam concrete structure sheaf.
In the above-mentioned technical solutions, light foam concrete structure sheaf upper and lower part is respectively equipped with steel wire.
In the above-mentioned technical solutions, longitudinally disposed protective bulkhead is equipped on the outside of the light foam concrete structure sheaf.
In the above-mentioned technical solutions, the protective bulkhead height H=0.5~15m.
In the above-mentioned technical solutions, the side lower part that the light foam concrete structure sheaf is connected with massif is set in slope surface
It sets, the slope surface is evenly equipped with the antiskid anchor studs that light foam concrete structure sheaf and massif are inserted into both ends respectively from top to bottom.
In the above-mentioned technical solutions, the stepped knot in side that the light foam concrete structure sheaf is connected with massif
Structure.
In the above-mentioned technical solutions, road shoulder is equipped on the outside of the road surface structare layer.
In the above-mentioned technical solutions, guardrail is equipped at the top of the road shoulder.
In the above-mentioned technical solutions, the thickness L=0.5m of the protective bulkhead.
The roadbed filling structure in the precipitous section in the utility model mountain area has the advantages that one, utilizes light foam
Concrete structure it is Lightness, slopes are carried out after part changes and fill out, is less than due to changing the roadbed loading after filling out and changes the weight for filling out part
Amount, reduces the slip moment of roadbed itself, it is ensured that and the stabilization of ancient slide body increases the stability against sliding of roadbed, without
Antiskid processing specially is done, circuit surface need not be also adjusted and increase highway mileage, reduce the difficulty of anti-slide design and construction.Two, it keeps away
Exempt from the drawbacks of height fills out bring stability problem and a large amount of land occupation resources, especially if route is adjacent with river, nothing
River need to be occupied, so as to avoid the unfavorable factor to river flood discharge.Three, the big bring high slope rockmass of earth excavation amount is avoided
Cost and adverse effect to environment.
Detailed description of the invention
Fig. 1 is to fill structural schematic diagram made of the conventional embankment formula barricade engineering method of the prior art；
Fig. 2 is to fill structural schematic diagram made of the high raising digging engineering method of routine of the prior art；
Fig. 3 is the structural schematic diagram of the roadbed filling structure in the precipitous section in the utility model mountain area.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and embodiments, but the embodiment should not be understood
For limitations of the present invention.
Fig. 1 and the roadbed filling structure in existing precipitous section shown in Fig. 2 have had a detailed description in the background technology, herein
It repeats no more.
Referring to Fig. 3, the roadbed filling structure in the precipitous section in the utility model mountain area, including what is be arranged close to 1 side of massif
Roadbed and the road surface structare layer 2 being set on roadbed, the roadbed are light foam concrete structure sheaf 3.
3 upper and lower part of light foam concrete structure sheaf is respectively equipped with steel wire 4.
Longitudinally disposed protective bulkhead 5 is equipped on the outside of the light foam concrete structure sheaf 3.
Protective bulkhead 5 the height H=0.5~15m, the thickness L=0.5m of the protective bulkhead 5.As it can be seen that being done relative to conventional
The embankment formula barricade 10 of method, the protective bulkhead 5 can be made thin, and not only weight is small and land occupation is few.
The side lower part that the light foam concrete structure sheaf 3 is connected with massif 1 is arranged in slope surface 3.1, the slope surface
3.1 are evenly equipped with the antiskid anchor studs 6 that light foam concrete structure sheaf 3 and massif 1 are inserted into both ends respectively from top to bottom.Certainly,
It the side that the light foam concrete structure sheaf 3 is connected with massif 1 can also be with stepped structure.
Road shoulder 7 is equipped on the outside of the road surface structare layer 2.Guardrail 8 is equipped at the top of the road shoulder 7.
Obviously, it is practical without departing from this can to carry out various modification and variations to the utility model by those skilled in the art
Novel spirit and scope.If in this way, these modifications and variations of the present invention belong to the utility model claims and
Within the scope of its equivalent technologies, then the utility model is also intended to include these modifications and variations.
The content being not described in detail in this specification belongs to the prior art well known to professional and technical personnel in the field.
