Abstract
The utility model discloses a prop up fender formula roadbed structure, including supercrust, barricade and road bed layer, wherein, the road bed layer includes road bed soil, first drainage blanket, second drainage blanket and vertical drainage passageway, the both ends of vertical drainage passageway communicate first drainage blanket and second drainage blanket respectively, the vertical drainage passageway includes wall side drainage channel and central drainage channel, a wall side drainage channel and a barricade contact, the second drainage blanket passes a barricade and outside drainage facility intercommunication. This prop up fender formula roadbed structure is through first drainage blanket, second drainage blanket and vertical drainage passageway, can realize simultaneously horizontal drainage and vertical drainage in order to obtain good drainage system, wherein, wall in a vertical drainage passageway side drainage channel and a barricade contact have approximate side slope drainage's characteristics, and the both ends that make horizontal drainage blanket go out the log raft to the outside drainage facility in along propping up the barricade fast, have strengthened prop up fender formula roadbed structure's stability.
Description
Technical field
The utility model relates to a kind of civil engineering facility, and particularly one props up gear formula road structure.
Background technology
Along with the fast development of special line for passenger trains, high-speed railway and speedway, the fund input of soft foundation settlement Control has occupied the larger specific gravity of construction investment.Railway conventional at present or highway subgrade structure have multiple, wherein a kind of is retaining roadbed structure with retaining wall, the roadbed rectangular in cross-section of this retaining roadbed structure, the outside, both sides of roadbed is respectively equipped with a retaining wall, and railway or highway construction are on the roadbed of centre.This retaining roadbed structure has that area occupied is little, joint space-efficient feature, therefore can protect existing building, thus can reduce expropriation of land and removal etc.But, this retaining roadbed structure with retaining wall of prior art, roadbed inside is too closed, on drainage, often only consider horizontal cross draining, horizontal cross drainage path is long, and drainage effect is poor, do not consider the problem that rainwater infiltrates, subgrade drainage can not be got rid of more in time yet.Therefore, need a kind of have good drainage system be used for get rid of subgrade drainage fast, strengthen the retaining roadbed structure of retaining roadbed stability.
Utility model content
The technical problems to be solved in the utility model is: overcome the problems referred to above, provides a kind of horizontal drainage and vertical drainage of simultaneously realizing to obtain a gear formula road structure of good drainage system.
To achieve these goals, the technical solution adopted in the utility model is such: of the present utility model gear formula road structure, comprise supercrust, prop up barricade and base course, wherein, described base course comprises subgrade soils, first row water layer, second row water layer and vertical drainage passage, the two ends of described vertical drainage passage are communicated with first row water layer and second row water layer respectively, described vertical drainage passage comprises wall side drainage channel and Central Drainage passage, described wall side drainage channel contacts with a barricade, described second row water layer is communicated with externally drained facility through a barricade.
Further, as a kind of concrete form of structure, first row water layer described in the utility model and second row water layer adopt crushed gravel material to fill.
Further, as a kind of concrete form of structure, vertical drainage passage described in the utility model adopts crushed gravel material to fill.
Further, as a kind of concrete form of structure, in second row water layer described in the utility model, be provided with airduct.
Further, as a kind of concrete form of structure, the bottom of second row water layer described in the utility model is equipped with soil engineering drainage material.
Further, as a kind of concrete form of structure, soil engineering drainage material described in the utility model is anti-seepage geomembrane, splash guard or geotextiles.
Compared with prior art, the utility model has the advantage of: this gear formula road structure is by first row water layer, second row water layer and vertical drainage passage, horizontal drainage and vertical drainage can be realized to obtain good drainage system simultaneously, wherein, described vertical drainage passage comprises wall side drainage channel and Central Drainage passage, described wall side drainage channel contacts with a barricade, there is the feature of approximate slope drainage, make the two ends of horizontal drainage layer be discharged to the outside in drainage by water rapidly along a barricade, enhance the stability of a gear formula road structure.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model;
In figure: 1. supercrust; 2. a barricade; 3. first row water layer; 4. second row water layer; 5. wall side drainage channel; 6. Central Drainage passage; 7. subgrade soils; 8. externally drained facility.
Detailed description of the invention
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with the utility model.
The utility model as shown in Figure 1 props up the preferred embodiment of gear formula road structure, comprise supercrust 1, barricade 2 and base course, wherein, described base course comprises subgrade soils 7, first row water layer 3, second row water layer 4 and vertical drainage passage, the two ends of described vertical drainage passage are communicated with first row water layer 3 and second row water layer 4 respectively, described vertical drainage passage comprises wall side drainage channel 5 and Central Drainage passage 6, described wall side drainage channel 5 contacts with a barricade 2, and described second row water layer 4 is communicated with externally drained facility 8 through a barricade 2.Described first row water layer 3 and second row water layer 4 adopt crushed gravel material to fill.Described vertical drainage passage adopts crushed gravel material to fill.Airduct is provided with in described second row water layer 4.The bottom of described second row water layer 4 is equipped with soil engineering drainage material.Described soil engineering drainage material is anti-seepage geomembrane, splash guard or geotextiles.
Of the present utility model gear formula road structure is by first row water layer 3, second row water layer 4 and vertical drainage passage, horizontal drainage and vertical drainage can be realized to obtain good drainage system simultaneously, wherein, described vertical drainage passage comprises wall side drainage channel 5 and Central Drainage passage 6, described wall side drainage channel 5 contacts with a barricade 2, there is the feature of approximate slope drainage, water is discharged to the outside in drainage 8 along a barricade 2 by the two ends of horizontal drainage layer rapidly, enhances the stability of a gear formula road structure.Described first row water layer 3 and second row water layer 4 adopt crushed gravel material to fill.Described vertical drainage passage adopts crushed gravel material to fill.Be provided with airduct in described second row water layer 4, utilize natural wind or add blast to accelerate the eliminating to roadbed internal water, there is certain environmental benefit.The bottom of described second row water layer 4 is equipped with soil engineering drainage material, and described soil engineering drainage material is anti-seepage geomembrane, splash guard or geotextiles, can prevent the downward seepage flow collecting subgrade drainage in horizontal drainage layer, enhance the drainage effect of roadbed.
