Description
Technical field
The present invention relates to technical field of building construction is and in particular to a kind of weak soil collapse concrete pavement construction method.
Background technology
The reason ftracture in concrete road surface has a lot：Such as：Concrete water-cement ratio is excessive, and the concrete pavement maintenance cycle is not
Foot, uneven settlement of foundation, Subgrade Compaction is uneven, and concrete plate area is excessive etc..Regardless of reason, road surface is opened
Split and caused due to stress, concrete water-cement ratio is excessive and concrete pavement maintenance cycle deficiency can produce shrinkage stress, ground
Base differential settlement and Subgrade Compaction is uneven can produce settlement stress, concrete plate area cross conference produce temperature should
Power.The main member of concrete road surface opposing cracking is reinforcing bar, but effect of prestressed is inconspicuous in putting into practice engineering.
Bituminous concrete, as high grade pavement preferred material, has plurality of advantages.But due to being increased by the volume of traffic, ring
Border change, temperature change, humidity change, frost action, construction, adopt the factor such as material and maintenance impact, occur in that multiple
Asphalt Pavement Damage, the such as crack of bituminous paving, rut and Moisture Damage etc..Those diseases are not only brought various each to road traffic
The hidden danger of sample, can cause the intensity decreases on roadbed, road surface, have influence on the normal use of road；Also greatly shorten asphalt road simultaneously
The service life in face, and also result in no small economic loss, this is a problem that can not be ignored.
Content of the invention
In view of the shortcomings of the prior art, the technical problem to be solved is to provide that a kind of fastness is good, splits
Stitch less, realize speed of application soon, save Load materials simultaneously, reduce the weak soil collapse concrete road surface of cost of paving the way further
Construction method.
For solving above-mentioned technical problem, the technical solution used in the present invention is：A kind of weak soil collapse concrete road surface
Construction method, comprises the steps：
（1）To weak soil matrix treatments：Desilt, that slag of delaying changes after filling out layered rolling again is smooth；
（2）The preparation of semi-rigid type base raw material：The cement stabilized macadam that semi-rigid type base raw material is 5% for cement content, should be by
Cement stabilized macadam mass ratio is 102:120:1390-1400:The cement of 650-660, water, rubble and stone flour mix
Arrive；
（3）The construction of semi-rigid type base：By step（2）The cement stabilized macadam obtaining tiles to step（1）Process after soft
In soil matrix matter, pave, roll and complete and health；
（4）Pave and vibrate：Concrete for half dry scene mixing once paves the concrete flag allowing to reach
Maximum plate thickness is 22～24cm；The maximum gauge that the commerical ready-mixed concrete of plasticity once paves is 26cm；Exceed once
During the maximum gauge paving, should pave at twice and vibrate, the interval time of two-layer making must not exceed 3Omin, lower thickness
It is approximately more than upper strata, and lower thickness is 3/5；Every time the paving, vibrate, flattening, wiping one's face and should continuously construct, in such as needing of concrete
Disconnected, construction joint should be set, its position should be in the seaming position of design code；
（5）Seam is constructed：Pull bar was installed before formwork erection after-pouring concrete, and the pull bar of longitudinal construction joint then passes through drawing of template
Rod aperture is installed, and longitudinal joint groove preferably uses joint saw sawing after the concrete is cured；Joint plate can also be imbedded in casting process, wait to mix
I.e. formation slot is extracted after solidifying soil initial set；During saw kerf, concrete can be carried out after should reaching 5～10Mpa intensity, also can be by
Scene examination saw determines；
（6）Floating and anti-skidding：After cement concrete pavement surface concreting, mechanical troweling is adopted to concrete road surface, and
With the trench saw, road surface is sawn into the little translot of deep 5～6mm, wide 2～3mm, spacing 2Omm；
（7）Maintenance and joint filling：After the concrete slab face of doing finishes, uniformly spray Vinylidene Chloride etc. (by superchlorinated polyvinyl chloride resin, molten
Agent oil and phthalic acid dibutylester, are formulated by 10%, 88% and 3% weight ratio), make the air-locked film of formation keep film
The moisture of inner concrete, wet curing；Using PVC cement and bitumastic, gap can be filled with.
Above-mentioned weak soil collapse concrete pavement construction method, described step（6）Middle cement concrete pavement surface mixes
After solidifying soil pours, road pavement sprays JR-01 concrete cement ground metope curing agent, produces chemical reaction by permeating with concrete
And and the calcium carbonate of periphery produce chemical reaction, and then the density and hardness of Concrete Structure from the inside to surface.
Above-mentioned weak soil collapse concrete pavement construction method, described step（7）In, joint seal is operated in concrete initial set
After carry out, during joint seal, should first remove the debris such as silt particle in clean gap.
Above-mentioned weak soil collapse concrete pavement construction method, described step（2）Cement stabilized macadam by mass ratio
For 102:120:1390-1400:The cement of 650-660, water, rubble and stone flour mix and obtain, and preferred mass ratio is
102:120:1393:655.

The easy construction of agent, only need to spray and brush on road surface that i.e. achievable concrete road surface is preferably wear-resisting, Hardening and blast
Effect.
2nd, weak soil collapse concrete pavement construction method of the present invention, improves the energy that prolonged and repeated deformation resisted by concrete
Power, the temperature of concrete road surface surrounding environment, the temperature moment is among variation, and the dilatation of concrete plate is subject to structure again
The constraint of layer, thus the Forces of plate also the moment is among tension and compression change repeatedly, concrete tensile strength will be caused
Reduce.And adopt prestressed concrete pavement, make concrete synchronous that tension to occur, there is not problem of Cracking, also due to draw should
The number of times that power occurs is few, greatly reduces the possibility of concrete drawing crack, thus improves the serviceability of concrete road surface.Work
Journey practice have shown that, even if indivedual cracks, as long as the stress of cold-drawn low-carbon wire is within proportional limit, these cracks will be with
The disappearance of the temperature difference and close, concrete still can be subject to compressive pre-stress.
