Description
Technical field
This utility model relates to a kind of stretch-proof road structure, belongs to building field.
Background technology
In general, highway adapts to 120 kilometers/hour or higher speed, and there are more than 4 tracks on road surface
Width.Centre arranges dividing strip, uses bituminous concrete or cement concrete high class pavement, is provided with complete mark, graticule, letter
Number and illuminator；Forbid that pedestrian and non motorized vehicle is on the way walked, with All other routes use crossings on different level, pedestrian's overbridge or
Tunnel passes through.But highway is after a long time use, due to the trickle variation of the earth's crust, express highway roadbed meeting is stretched and leads
Cause road surface cracks, and causes travel safety to reduce.
Summary of the invention
The deficiency existed for prior art, technical problem to be solved in the utility model is to provide a kind of stretch-proof
Road structure, improves the stretch-proof energy of highway, improves travel safety.
For solving above-mentioned technical problem, this utility model adopts the technical scheme that, a kind of stretch-proof road structure, including
Bottom rammed earth layer, bottom rammed earth layer is provided with bottom cement layer, and bottom cement layer is provided with bottom stone layer, bottom stone
It is provided with middle part extended layer on Ceng, middle part extended layer is provided with top stone layer, top stone layer is provided with top cement
Layer；Described middle part extended layer includes upper layer of silicon glue-line and lower floor's layer of silica gel, is provided with between upper layer of silicon glue-line and lower floor's layer of silica gel
Extension board, extension board is provided with some steady braces, and the top of steady brace is arranged in upper water mud layer；Described extension board
On be provided with some segmental arcs be arrangeding in parallel, the thickness that distance is upper water mud layer on the arc top of segmental arc to extension board upper surface
The 1/3.86 of degree, the spacing of segmental arc is 0.8 meter, and the thickness of extension board is the 1/3.8 of the thickness of upper water mud layer；Described upper strata
The upper surface of layer of silica gel and the lower surface of lower floor's layer of silica gel are provided with bearing net；Some permeable holes it are provided with on described extension board.
Optimizing, above-mentioned stretch-proof road structure, described two adjacent steady braces are 73 degree of angles.
Optimizing, above-mentioned stretch-proof road structure, the thickness of described bottom cement layer and upper water mud layer is bottom rammed earth
The 1/1.65 of the thickness of layer, the thickness of top stone layer and bottom stone layer is that the 2/3 of the thickness of the layer is rammed in bottom.
The utility model has the advantage of that it can overcome the drawback of prior art, reasonable in design is novel.The application's
Roadbed is provided with upper layer of silicon glue-line, lower floor's layer of silica gel and extension board, and when roadbed is stretched, the segmental arc on extension board bears
Launch after tensile force, then filled roadbed by layer of silica gel and be stretched the gap of generation.Steady brace is used for will extend over plate and water
Mud layer is fixed, and so makes extension board can directly bear the pulling force of roadbed.But steady brace if provided as with extension board
Vertical then can be easily broken off, two adjacent steady braces are set to, in 73 degree of angles, be not easily broken also by the design of the application
And the pulling force of multiple directions can be sustained, improve practicality.Being disposed to of bearing net prevents layer of silica gel by crossing
Pressure do not result in deformation or occur to break away and affect the stability of roadbed.The thickness of stone layer is excessive, then please tilt can on road surface
Can property improve.The thickness of stone layer is too small, then the supporting role to cement layer is inadequate, and road surface is easily generated and subsides and crack, based on
Above-mentioned reason, the thickness of top stone layer and bottom stone layer is that the 2/3 of the thickness of the layer is rammed in bottom by the design of the application.Water
The blocked up meeting of mud layer causes the rising of construction cost, the too small meeting of cement layer thickness to cause easy crack, road surface.For the foregoing reasons, originally
The thickness of bottom cement layer and upper water mud layer is that the 1/1.65 of the thickness of the layer is rammed in bottom by the design of application.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
In figure: 1 be bottom rammed earth layer, 2 be bottom cement layer, 3 be bottom stone layer, 4 be upper layer of silicon glue-line, 5 for top
Stone layer, 6 be upper water mud layer, 7 be lower floor's layer of silica gel, 8 be extension board, 9 be steady brace, 10 be segmental arc, 11 for load-bearing
Net.
Detailed description of the invention
The technical characterstic of the present invention is expanded on further below in conjunction with the accompanying drawings with specific embodiment.
This utility model is a kind of stretch-proof road structure, including bottom rammed earth layer, bottom rammed earth layer is provided with bottom
Cement layer, bottom cement layer is provided with bottom stone layer, bottom stone layer is provided with middle part extended layer, on the extended layer of middle part
It is provided with top stone layer, top stone layer is provided with upper water mud layer；Described middle part extended layer include upper layer of silicon glue-line and
Lower floor's layer of silica gel, is provided with extension board between upper layer of silicon glue-line and lower floor's layer of silica gel, extension board is provided with some steady braces,
The top of steady brace is arranged in upper water mud layer；Some segmental arcs be arrangeding in parallel, arc it is provided with on described extension board
The 1/3.86 of the thickness that distance is upper water mud layer of arc top to the extension board upper surface of section, the spacing of segmental arc is 0.8 meter, prolongs
