Abstract
The utility model discloses a kind of repairing type emulsified asphalt road surface, including old layer roadbed, metalling, concrete layer, coal tar pitch layer and emulsified asphalt slurry seal are equipped with the old layer roadbed successively;Geotechnical grid is equipped with metalling, the concrete layer is located at geotechnical grid upper end in the geotechnical grid lower end, coal tar pitch layer.The utility model has advantages below and effect:It is by geotechnical grid that concrete layer and coal tar pitch layer one is fixed, the structural strength for repairing road surface is enhanced, extends service life.
Description
Technical field
The utility model is related to pavement construction field, more particularly to a kind of repairing type emulsified asphalt road surface.
Background technology
Existing road surface is spread just using cement or pitch mostly.After the completion of road surface, whole road surface is to be relatively fixed,
A certain degree of breakage necessarily occurs in road surface after use after a while, and the Re-paving transformation for causing road surface is always building
The focus that road work person pays close attention in industry.Wherein the Moisture Damage of bituminous paving be mainly shown as on road surface loosely, produce hole
Groove etc., directly contributes the destruction of asphalt pavement structural layer, has had a strong impact on the use function on road surface, shortens the use longevity on road surface
Life.And this disease is difficult in road surface operation phase maintenance, it must again be spread from roadbed to road-surface milling, cause unnecessary waste.
Utility model content
The purpose of this utility model is to provide a kind of pit and repairs the high repairing type emulsified asphalt road surface of rear stability.
Above-mentioned technical purpose of the present utility model technical scheme is that:A kind of repairing type emulsification drip
Metalling, concrete layer, coal tar pitch layer and emulsification are equipped with blue or green road surface, including old layer roadbed, the old layer roadbed successively
Asphalt slurry seal coat;Geotechnical grid is equipped with metalling, the concrete layer is dripped in the geotechnical grid lower end, the coal
Cyan layer is located at geotechnical grid upper end.
By using above-mentioned technical proposal, the pit of old layer roadbed is cleaned out, metalling is then filled by pit bottom
Portion is filled and led up, and geotechnical grid is first placed after filling and leading up, then concrete layer is poured into, and forms concrete layer, is stood after stabilization, then
Coal tar pitch is inserted in pit on toward geotechnical grid and above geotechnical grid, coal tar pitch layer is formed, an emulsification drip is finally laid
Blue or green slurry seal, maintain an equal level with old layer roadbed and seals;On the one hand concrete layer and coal are enhanced by the setting of geotechnical grid
The combination degree of bitumen layer, on the other hand serves the spacing power of radial direction in pit, enhancing tension, shearing resistance, resistance to compression and anti-impact
The intensity hit, improves combination property.
It is of the present utility model to be further arranged to:The concrete layer is less than geotechnical grid thickness in geotechnical grid thickness
1/3rd, the thickness of the coal tar pitch layer is more than 2/3rds of geotechnical grid thickness.
By using above-mentioned technical proposal, concrete layer is more used to carry out metalling to fix after smooth filling, separately
On the one hand it is used to position geotechnical grid, geotechnical grid is erect, finally by the full remaining geotechnological lattice of laying filling after coal tar pitch layer
In the cavity of room, the structural strength of whole repair layer is played.
It is of the present utility model to be further arranged to:It is in latticed vertical-shaped plate, institute that the geotechnical grid, which includes polylith distribution,
State and multiple through holes are distributed with vertical-shaped plate.
By using above-mentioned technical proposal, through hole is opened up between the vertical-shaped plate in geotechnical grid, is realized between concrete layer
Be interconnected, and coal tar pitch layer between connection, it is to avoid between the level that the single cavity in geotechnical grid is formed
Relevance is too small, and causes structure unstable.
It is of the present utility model to be further arranged to:GSZ is also equipped between the metalling and geotechnical grid.
It is of the present utility model to be further arranged to:The GSZ is steel wire.
By using above-mentioned technical proposal, GSZ is made up of steel wire so that GSZ has stronger knot
Structure intensity and service life, on the other hand can play the position-limiting action to metalling, it is ensured that between the layer and pit bottom
Stability.
In summary, the utility model has the advantages that:By geotechnical grid by concrete layer and coal tar pitch layer
One is fixed, enhances the structural strength for repairing road surface, extends service life.

Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing 1 and Fig. 2.
A kind of repairing type emulsified asphalt road surface, including old layer roadbed 1, first by the pit 11 in old layer roadbed 1
Reason is clean, and then directly 20 ~ 23cm of laying rubble is tamped, and forms metalling 2;Then again in the more upper table of metalling 2
Face is equipped with the steel wire as GSZ 7, and metalling 2 is spacing in pit 11, and the contact of the side wall of pit 11 well,
Positioned simultaneously.
After GSZ 7 has been laid, the vertical-shaped plate quilt on geotechnical grid 4, geotechnical grid 4 is placed on GSZ 7
Stretching forms distributed in grid, and the overall profile of pit 11 is filled, after the completion of geotechnical grid 4 is positioned, then casting concrete
On geotechnical grid 4, height is not higher than 1/3rd of the height of geotechnical grid 4, and concrete can be permeated by GSZ 7
Into metalling 2, metalling 2 and the progress of GSZ 7 are solidified, upper strata is positioned geotechnical grid 4, form concrete
Layer 3.
After the completion for the treatment of that concrete layer 3 is poured, then toward coal tar pitch is filled in the pit 11, geotechnical grid 4 is annihilated completely, Gu
Coal tar pitch layer 5 is formed after change, the formation again of the whole roadbed of pit 11 is completed, passes through the common of geotechnical grid 4 and GSZ 7
It is spacing so that whole repair has structural strength, and because itself is Structured cured substantially so that can more old layer roadbed 1
The end face of pit 11 carries out good fixation.
Last coal tar pitch layer 5 is completed after laying, is carried one coating emulsified asphalt slurry seal 6 of laying, is carried out the finishing on road surface, will
The roadbed of reparation mutually maintains an equal level with the end face of old layer roadbed 1, realizes good repairing.
Specific embodiment is only to explain of the present utility model, and it is not to limitation of the present utility model, this area
Technical staff can make the modification without creative contribution to the present embodiment as needed after this specification is read, but only
All to be protected in right of the present utility model by Patent Law.
