Abstract
The invention discloses a cement pavement splitter. The cement pavement splitter has the advantages that the structure is simple, and the design is reasonable; when a cement concrete pavement slab is knocked and broken by an impact hammer, the top surface of the pavement slab forms cracks which are fine as hair, and the oblique cracks are shown in the pavement slab, so that no matter whether the road pavement slab is horizontal or vertical, the cracks are undercut and staggered, and the slabs are mutually embedded; although the stress of the road pavement slab is released, the certain structure strength and bearing capacity are still realized; after an asphalt concrete surface layer is covered, the characteristics of uniform distribution and uniform adhesion force of asphalt concrete are realized, so that the water stabilizing layer required by the rectifying of black and white appearance in the traditional pavement is not used, the engineering investment is greatly reduced, and the road maintenance cycle is shortened; after rectifying, the settling value of road turn is small, the bearing capacity is uniform, the reflection joint is eliminated, and the service life is long.
Description
Technical field
The invention belongs to road maintenance maintenance technology field, and in particular to a kind of cement pavement splitting machine.
Background technology
Ended for the end of the year 2016,4,060,000 kilometers of highway in China total kilometrage, wherein 130,000 kilometers of highway total kilometrage, grade
4,060,000 kilometers of above kilometer total kilometrage, 57.5 ten thousand kilometers of secondary standard kilometer.In highway, it is cement concrete to account for 10%
Road surface, it is cement concrete pavement that sizable ratio is accounted in remaining standard highway.According to China's highway layout service life, entirely
State-owned quite a few road needs to implement the inside, roadbed maintenance, needs waist to adopt " morning-night " Pavement Improvement, and this is one great
Engineering.It is existing《Specification》It is required that road " morning-night " transformation is done using first cement stabilizing layer of laying before bituminous paving is overlayed
Method, the weak point of this technical measures is apparent:Roadbase bearing capacity is uneven, and deflection value peak value is big, asphalt overlaying
It is poor that layer is combined with former cement concrete layer, and often the uneven reflection crack of presentation bulk strength, load type are launched crack, temperature and answered
Power launches crack, and this is road maintenance common quality defect.
Such as " gate-type is crushed " and " impact grinding " technology, its result is to produce irregular cracking, the block that adjacent slits are surrounded
Spend for 0.4~0.6 square metre, measure and press each time steady rear settling amount, survey after the settling amount for measuring every time is ditto once pressed surely
The settling amount for obtaining compares, when the difference of variable quantity before and after it is less than 5 millimeters, then it is assumed that the steady technique of pressure has reached construction requirement.
It is actual to have the technical effect that:(1) the plate Angle Position for coming to nothing often is difficult to tamp;Road surface longitudinal cracking defect or longitudinal fluting band, make
Easily there is longitudinal cracking into overlay;Surfacing after broken punishment, overlay is poor with the cohesive force on old road, easily occurs
Overlay gathers around bag breaks down;(2) it is difficult to eliminate plat-bottom escape, the plate after crushing is still within " cantilever slab " state, is compacted
Surface afterwards is more smooth, causes overlay reflection crack and breaks down easily occur.
Accordingly, it would be desirable to a kind of new cement pavement splitting machine is solving the above problems.
The content of the invention
To solve the defect that prior art is present, there is provided a kind of cement pavement splitting machine.

Evaluate.Step 1) in using cement pavement splitting machine as above cleave cement concrete pavement.
Step 1) in using jump bit splitting cement concrete pavement after, discontinuous of the concrete roadway surface band for obtaining
Silking.Old concrete plate Jing after splitting either level to or it is vertical, its crackle present occlusion staggeredly, between plate mutually
It is chimeric, both released old concrete panel stress, maintain again old concrete plate it is cracked after still there is certain structural strength
And bearing capacity, old concrete and overlay realization preferably combination, prevent reflection crack, road surface passage, gather around the diseases such as bag, fill
Divide old road concrete plate regeneration.
2), to roadbed under plate face come to nothing layer injection geo-polymer;Wherein, geo-polymer is inorganic mineral polymerization
Thing.The inorganic mineral polymer five poisonous creatures: scorpion, viper, centipede, house lizard, toad are harmless, and its slurry consolidation body volume does not expand, do not shrink.Step 2) in using static pressure to
Under plate face roadbed come to nothing layer injection geo-polymer slurries.
Step 2) in roadbed under plate face come to nothing layer injection geo-polymer after, it is further comprising the steps of:
First, with forcing press vibroroller cmpacting road surface;
2nd, road surface floating dust is blown out;
3rd, road surface is rinsed with water;
4th, road surface natural drying.
3) rigid pavement or flexible pavement, are overlayed in plate face, the cement pavement of construction overlay is obtained.
Step 3) in first deflection value detection is carried out to plate face, rigid pavement or flexible pavement are then overlayed in plate face.It is curved
After heavy value is qualified, mating formation for rigid pavement or flexible pavement is being carried out, preventing underproof situation.Establishing criteria is evaluated
PCI carries out ground polymers Grouting for disease structure sheaf inside difference level section, and after testing punishment position deflection value meets design and wants
Ask or with road to occur to cleave crusher machine using old cement concrete road after destruction section road surface bearing capacity is basically identical.
The cement pavement overlay construction method of the present invention cleaves cement concrete pavement using jump bit, implements ground polymers
Rigid pavement or flexible pavement are overlayed after slip casting.The residual structure strength of old concrete can be made full use of, higher roadbed is formed
Bearing capacity, fully by old road concrete plate regeneration.Its economic effect is:Low-carbon (LC), section material, saving construction period, save
Construction fund.
