Description
Technical field
The invention belongs to the technical field of road design, relate in particular to a kind of novel drainage type speedway emergency stopping lane only road structure.
Background technology
The emergency stopping lane only of speedway is positioned at the outside of main line runway, sails the following nothing more than three kinds of situation of vehicle of emergency stopping lane only into: 1. go transboundary; Because the bigger or improper vehicle short time of causing of overtaking other vehicles of vehicle flowrate goes on emergency stopping lane only, generally transboundary traffic time is very short; 2. stop in emergency; Because running into emergency, vehicle trouble or driver need temporary parking; 3. cruising; At uphill way, high capacity waggon, goes and have no alternative but get into emergency stopping lane only in order not influence the normal current of other vehicles because self load-carrying is bigger, and the speed of a motor vehicle is slower.The speed of a motor vehicle of sailing emergency stopping lane only into generally all is lower than 60km/h.
Emergency stopping lane only all is to adopt the road structure identical with the main line runway mostly; Adopt the emergency stopping lane only of this structure to have following drawback: 1, drainage effect is relatively poor; Table water in road is most of can to flow to curb (gutter) and beyond the roadbed through road surface horizontal wall inscription and longitudinal gradient; And have only fraction (about 5%～15%, as to distribute relevant) to penetrate in the road structure along pavement joint, crack and surface layer space with road table water state with table crack, road, become and cause that the bad main water of road structure damage by water originates.When, surface pond smooth when physical features and embankment were short, water might infiltrate the road structure from side direction.In addition, the motion of phreatic capillarity and evaporation water also might cause water to get into road structure inside.Get into the water in the road structure, if untimely discharge will be soaked structural material and roadbed, its intensity is descended, distortion increases.Even more serious is, forms High-Pressure Water down at the driving load action, quickens the generation of the many diseases in road surface, like loose, the purt mud of purt mud, faulting of slab ends and the fracture of cement concrete pavement and flexible pavement with cheat groove etc.; 2, the road surface is " extremely " road surface, when disease takes place on the road surface, need the disease place have been dug, and the pitch that paves again carries out just can coming into operation after the maintenance of a period of time, operation complicacy not only, and also the engineering time is long.
Summary of the invention
The technical problem that the present invention will solve provides a kind of novel drainage type speedway emergency stopping lane only road structure, is the structure on " work " road surface.
In order to solve the problems of the technologies described above; The present invention provides following technical scheme: a kind of novel drainage type speedway emergency stopping lane only road structure; Comprise successively from top to bottom: course of blocks, compacting sand cushion, geotextiles loaded filter, hole concrete drainage blanket, basic unit and roadbed; The heated bitumen sealing is adopted in said course of blocks, compacting sand cushion, geotextiles loaded filter, hole concrete drainage blanket and junction, main line runway side, and basic unit's end face is provided with 3% horizontal wall inscription.
Compared with prior art, the invention has the advantages that: 1, the present invention is removable " means of subsistence face ", and the block seam is filled out to irritate with fine sand and formed, and under extraneous load action, block is not individually but spreads load with reciprocal interlocking.It has cheap, construction flexibly, characteristics such as antiskid and resisting temperature deformation performance be good, easy to maintenance, reusable.2, propose the crown slope of design 3%, general flexible pavement has improved 1%, can improve the drainage efficiency of road table effectively.
Further, said course of blocks thickness is 10～16cm.
Description of drawings
Below in conjunction with accompanying drawing and embodiment technical scheme of the present invention is further specified:
Fig. 1 is the structural representation of a kind of embodiment of the novel drainage type speedway of the present invention emergency stopping lane only road structure.
The specific embodiment
As shown in Figure 1; The novel drainage type speedway of the present invention emergency stopping lane only road structure; Comprise successively from top to bottom: 12cm course of blocks 1,3cm compacting sand cushion 2, geotextiles loaded filter 3,6cm hole concrete drainage blanket 4, basic unit 5 and roadbed 6; Said course of blocks 1, compacting sand cushion 2, geotextiles loaded filter 3, hole concrete drainage blanket 4 adopt the heated bitumen sealing with junction, main line runway 7 side, and basic unit's 5 end faces are provided with 3% horizontal wall inscription.
Course of blocks 1 one-tenth-value thickness 1/10 can be chosen with reference to table 1
| Accumulative total equivalent axle load effect number of times/inferior | ＜2×10 5 | 2×10 5～5×10 5 | 5×10 5～2×10 6 | ＞2×10 6 |
| Block thickness (cm) | 10 | 12 | 14 | 16 |
Table 1
When the present invention is used for speedway emergency stopping lane only making; Should be with main body road structure with regard to the main line road surface, promptly basic unit 5 and following structure are identical with main line runway 7, needn't also should not design separately; Otherwise be unfavorable for the resistance to overturning of road structure, and be unfavorable for construction.After basic unit 5 accomplishes, promptly carry out the waterproofing course design.For course of blocks 1, because face joint is many, water percolating capacity is a lot of greatly than flexible pavement, therefore, must carry out the inner Drainage Design of road structure.At first at basic unit's 5 surface sprinkling mulseal water-proof tack coats, play the water shutoff effect, making hole concrete drainage blanket 4 then, through the space concrete water that infiltrates discharged beyond the road structure through the road camber horizontal wall inscription.On hole concrete drainage blanket 4, lay geotextiles loaded filter 3, geotextiles loaded filter 3 is double-deck geotextiles, plays a part to isolate and draining, avoids bedding sand to drain in the layer of concrete of space and stops up the space.Geotextile laying is a making compacting sand cushion 2 after accomplishing, and compacting sand cushion 2 requires paving thickness even, and surfacing is closely knit.After compacting sand cushion 2 makings are accomplished is exactly putting of course of blocks 1 block, and block requires the fissure of displacement to put, and notes putting smooth, and joint gap must be controlled within the scope of design.
For a person skilled in the art, under the prerequisite that does not break away from structure of the present invention, can also make some distortion and improvement, these also should be regarded as protection scope of the present invention, and these can not influence effect and practical applicability that the present invention implements.
