Background technology
Low-grade highway is pressed road skill level, comprising: three, level Four road, etc. outer level road, temporary road and pioneer road etc., comprise county, township, village's road according to road administrative grade.Rudimentary highway is the important component part of highway in China net, mileage is many, area coverage is wide, its mileage accounts for the more than 3/4ths of national mileage in highway open to traffic, connect vast county, township, village, serve agricultural, rural economic development and peasant's trip, the important infrastructure that is related to construction of a comfortably-off society comprehensively and builds a harmonious society.
Basic unit, the subbase of tradition low-grade highway flexible face stratotype road structure, generally all adopt semi-rigid material as two grey Stabilized Soil, or rigid material is as cement stabilized soil.The road surface structare layer semi-rigid, rigid material forms, can only transmit cargo in vertical mode.Semi-rigid, rigid material contains carbon, can cause inevitable carbon emission, and environment is had to certain pollution.After peaking, the longterm strength of the flexible face stratotype road structure of tradition low-grade highway starts to glide, until can not meet the requirement of road desirable strength.The health of need to breaking in the time building of semi-rigid, rigid material, inconvenient vehicle and pedestrian's traffic trip.Because roadbed, subbase, basic unit's barrier performance of traditional highway are poor, highway is in operation and is easily destroyed and cause maintenance work frequently.
Utility model content
The purpose of this utility model is to provide a kind of environmental protection Ultra-low carbon, and seepage capability is strong, and longterm strength can not decline, and maintaining is simply for the flexible face stratotype road structure of low-grade highway.
The utility model is achieved through the following technical solutions: a kind of flexible face stratotype road structure for low-grade highway, comprise taking roadbed as matrix, on described roadbed, be equipped with the anti-power strengthening course of dredging, the anti-power strengthening course of dredging is provided with Kang Shu power basic unit, in described Kang Shu power basic unit, be also equipped with flexible cladding, described flexible face stratotype road structure one side is provided with gutter.Follow the strong basis sake theory in highway construction, the structures such as the cement that uses Kang Shu power basic unit to substitute the origin road structure to use, lime, concrete, it is raw material that Kang Shu power basic unit is used on-site soil, sand, stone, its proportioning is 2:3:5, add again the anti-power soil stabilizer of dredging, its thickness≤100mm, attribute is flexible, transmit cargo and can reduce the destructive rate of surface layer in the angle decomposition mode of 45 °, save maintenance cost.Kang Shu power basic unit energy Reusability, can further save cost, and reduces the pollution to environment.
Further, the described anti-power strengthening course of dredging is added and is resisted thin power soil stabilizer to form by road original soil.The anti-power strengthening course of dredging is added and is resisted thin power soil stabilizer to form by road original soil, and its thickness is generally 150 to 300mm, has good anti-seepage effect, can be because of the downslide of passage of time generation intensity.
Further, described flexible cladding is asphalt surface course.
Further, described flexible cladding is slurry seal.
Further, the two ends of described flexible cladding are provided with curb.Curb is set and can protects the stable of the primary structures such as runway; For the vehicle that mechanical breakdown occurs or run into emergency provides temporary parking position; Lateral clearance is provided, is conducive to safety, increase comfort; Can supply pedestrian, cyclists only; For being set, facility on road provides position; As the work-yard of maintenance operation; Not damaging under the prerequisite of highway structure, also can be used as the position of burying underground installation underground; Improve the bend sighting distance in excavation section, promote traffic safety; Make rainwater in the position discharge away from runway, reduce runway rain penetration, reduce pavement damage.
Further, described curb is rigidity curb.The rigidity curb arranging according to the related needs on road surface.
Further, described curb is light-duty curb.The light-duty curb arranging according to the related needs on road surface.
Further, described gutter is ecosystem soil ditch.Can gather materials on the spot, not need other materials to build.
The utility model compared with prior art, has the following advantages and beneficial effect:
(1) the anti-anti-thin power soil stabilizer of dredging the use of power strengthening course of this flexible face stratotype road structure is free of contamination.Through national authority Department certification, the anti-power soil stabilizer of dredging can be used for Drinking Water transmission & distribution aqueous systems.In other words, resist thin power soil stabilizer to enter human body harmless;
(2) this flexible face stratotype road structure longterm strength can not increase in time and decline, have good anti-seepage effect, the anti-power strengthening course of dredging has good barrier effect, and repairs simple, while carrying out road repair, do not need to break, do not affect vehicles and pedestrians;
(3) the anti-power strengthening course of dredging of this flexible face stratotype road structure, adopts soil, sand, Shi Jiakang to dredge power soil stabilizer (0.1% that consumption is weight ratio) composition, and its attribute is flexibility.Flexible structure layer transmits cargo and energy Reusability in the angle decomposition mode of 45 °;
(4) this flexible face stratotype road structure all adopts soil, sand, Shi Jiakang to dredge power soil stabilizer, and anti-production of dredging power stabilizing agent is emission of carbon not.
