Utility model content
The technical problems to be solved in the utility model is: overcome the problems referred to above, provides one can realize roadbed horizontal drainage, vertical drainage and slope drainage simultaneously, gets rid of the Quick drainage road structure that subgrade drainage also can improve subgrade stability fast.
To achieve these goals, the technical solution adopted in the utility model is such: Quick drainage road structure of the present utility model, comprise the side slope of road surface and both sides, road surface, the backplate being fixedly connected with both sides side slope is provided with between two side slopes, lattice guest cage is provided with on the downside of backplate, backplate soffit is vertically provided with airduct, airduct top is connected with backplate, be fixed on lattice guest cage inner bottom surface bottom it, vertical drainage passage is provided with on the downside of described lattice guest cage, horizontal drainage layer is connected on the downside of described vertical drainage passage, the first geotechnological water proof material layer is laid in the bottom of horizontal drainage layer, described side slope is equipped with band drain and is positioned at the second geotechnological water proof material layer inside band drain.
Further, as a kind of concrete form of structure, the quantity of vertical drainage passage described in the utility model is more than 2.
Further, as a kind of concrete form of structure, backplate described in the utility model adopts steel material to make.
Further, as a kind of concrete form of structure, vertical drainage passage described in the utility model and horizontal drainage layer adopt crushed gravel material to fill.
Further, as a kind of concrete form of structure, the first geotechnological water proof material layer described in the utility model adopts anti-seepage geomembrane, splash guard or geotextiles.
Further, as a kind of concrete form of structure, the second geotechnological water proof material layer described in the utility model adopts anti-seepage geomembrane, splash guard or geotextiles.
Further, as a kind of concrete form of structure, in lattice guest cage described in the utility model, be interspersed with steel mesh structure.
Further, as a kind of concrete form of structure, airduct described in the utility model has several through hole.
Compared with prior art, the utility model has the advantage of: this Quick drainage road structure arranges horizontal drainage layer, vertical drainage passage and slope drainage layer and forms three-dimensional draining road structure in roadbed, quick eliminating subgrade drainage, effectively prevent road surface from occurring frost heave, thaw collapse and frost boiling problem, adopt lattice guest basket structure, improve the stability of roadbed.
