Match.
Preferably, the ventilating layer is steel construction, including top plate, the top plate be symmetrically mounted at the bottom of multigroup left support plate
And right support plate, the left support plate and right support plate bottom are provided with bottom plate, right support plate, and bottom are exceeded on the right side of the bottom plate
It is shorter than left support plate on the left of plate.
Preferably, the rubble layer is trapezium structure, and rubble slice width degree is less than ventilating layer.
Preferably, the TGXG of the geogrids layer is steel TGXG.
Preferably, the pavement top is uniformly provided with capillary groove.
Compared with prior art, the utility model has the beneficial effects that：The utility model road structure is stablized, and can effectively prevent
The thawing for only answering frozen soil caused by road heating caused by sunlight road surface, effectively prevents because climate warming frozen soil melts
Caused by change the problem of roadbed expansion, the stability of road structure is greatly improved.

In figure：1 support column, 11 cylinders, 12 support fast, 13 crossbeams, 2 concrete layers, 3 ventilating layers, 31 top plates, 32 left supports
Plate, 33 right support plates, 34 bottom plates, 4 rubble layers, 5 microlith layers, 6 geogrids layers, 7 road surfaces.
Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
The every other embodiment obtained, shall fall within the protection scope of the present invention.
- 4 are please referred to Fig.1, the utility model provides a kind of technical solution：A kind of road structure of Frozen Ground Area, including branch
Dagger 1,1 top of the support column are provided with concrete layer 2, and 2 top of the concrete layer is provided with ventilating layer 3, the ventilation
3 top of layer is provided with rubble layer 4, and 4 surface of rubble layer is covered with microlith layer 5, and 5 top of the microlith layer is provided with geotechnological lattice
Grid layer 6,6 surface of the geogrids layer are equipped with road surface 7.
Wherein, the support column 1 includes crossbeam 13, and 13 bottom of the crossbeam is provided at both ends with supporting block 12, makes support force
That disperses is more uniform, and 12 bottom of the supporting block is both provided with cylinder 11, and cylinder 11 gos deep into lithosphere, ensures road knot
The stability of structure, 13 top of the crossbeam is equipped with groove, and 2 bottom of the concrete layer matches with crossbeam 13, ensure that branch
Support force is more uniform, and the ventilating layer 3 is steel construction, including top plate 31, the top plate 31 be symmetrically mounted at the bottom of a multigroup left side
Support plate 32 and right support plate 33, there are gaps among two pieces of support plates, and air or so is made to circulate, it is therefore prevented that the heat of road passes
Frozen soil is transported to, the left support plate 32 and 33 bottom of right support plate are provided with bottom plate 34, and 34 right side of the bottom plate exceeds right fagging
33, and 34 left side of bottom plate is shorter than left support plate 32, is convenient for the installation of two pieces of ventilating layers 3, and ensure that support is uniform, the rubble layer
4 be trapezium structure, and 4 width of rubble layer is less than ventilating layer 3, prevents stone to be scattered and stops that ventilation opening, trapezium structure have ensured public affairs
The stability of line structure increases forced area, and the TGXG of the geogrids layer 6 is steel TGXG, is enhanced
The intensity of pavement structure, 7 top of the road surface are uniformly provided with capillary groove, increase the frictional force of vehicle tyre and road, protect
The safety of road traveling is hindered.
Operation principle：Cylinder 11 gos deep into the stability that rock has ensured road structure, and crossbeam 13 and supporting block 12 ensure that
Support force is uniformly distributed, and ventilating layer 3 or so is divulged information, and can take away the heat that road surface hands down, rubble layer 4 reduces road
Thermal conductivity, it is therefore prevented that road causes frozen soil to melt since sunlight temperature increases, to which heat reaches soil layer, and microlith layer 5 is protected
The planarization for having demonstrate,proved road surface 7 ensure that the planarization of geogrids layer 6, geogrids layer 6 ensure that the intensity on road surface 7, prevent
The fracture on road surface 7.
