Brief description of the drawings
Fig. 1 is the profile of embodiment.
Embodiment
As shown in figure 1, a kind of temporary road rolling compacted concrete pavement reconstruction structure, through even out and filling-in compaction treatment after
Roadbed 1 of the flatness no more than 10mm is provided with concrete flag 2, and the both sides of concrete flag 2 are provided with gutter 3.Wherein
Concrete flag 2 is formed by the grinding coagulation soil to pave on roadbed 1 after rolling, and paving thickness is 30~35cm.Coagulation
There is transverse contraction joint on the surface of dirt road panel 2 every 10~15m saws, contracting seam slit width 1cm, deep 6cm, contracts and is filled in stitching using pitch horseshoe fat
Seam.
In the present embodiment the grinding coagulation soil of casting concrete road deck 2 by cement, water, GQ202 types retardation water reducing agent,
Sand, 5~20mm rubbles and 20~40mm rubble mixs form, and wherein cement consumption is 277kg/m3, grinding coagulation soil each component
Between weight ratio be cement：Water：GQ202 type retardation water reducing agents：Sand：5~20mm rubbles：20~40mm rubble=1：0.30：
0.015：2.60：2.45：2.45.
The concrete construction method of the present embodiment is as follows：
A, preparation of construction：Preparation of construction includes surveying and locating and roadbed treatment.
A1, surveying and locating：Center line of road and sideline are released according to drawing, the piecemeal line of road deck, set up temporary bench mark,
Checked during to construct.
A2, roadbed treatment：In order to ensure concrete road surface normal use, it is desirable to which roadbed 1 has enough structural thicknesses, solid
It is stable, uniformity.Such as roadbed 1 finds pit, loose disrepair phenomenon should carry out repairing makes its surfacing, and elevation, thickness
Degree, vertical and horizontal gradient is consistent with design, and its error amount should be in allowed band.Roadbed is answered closely knit smooth, and flatness is not more than 10mm,
Absolute altitude should be gone through, eminence (>It should 10mm) even out, lower (>10mm) using cement stabilized macadam or the filling-in of lean concrete 4 simultaneously
Compacting.The surface of roadbed 1 is cleaned up, and in order to prevent absorbing the moisture in grinding coagulation soil, roadbed 1 should be sprinkled water before paving
Wetting.
B, grinding coagulation soil is closed a position and paved：Transport to job site and closed a position after each component mix of grinding coagulation soil
And pave.
To ensure the mixing quality of concrete mix, construction is stirred using the forced action type with computer automatic control system
Mixing equipment is mixed and stirred；Because C30 graduation two concrete water amounts are few, it is longer to mix and stir for 6 times, determines to mix and stir by trial mix during construction
Control time, generally often disk 180s or so.The transport of concrete preferably uses dump truck, in order to reduce transportation reclaimed water
Denseness is lost caused by dividing evaporation, and wagon box planted agent keeps moistening, and transportation range should be advisable with the accessible distances of 30min, simultaneously
Take necessary covering methods.
Automobile storehouse face discharging using moving back laid process discharging successively, free fall cannot be greater than 1.5m during discharging, and windrow is high
Degree requires to be less than 80cm, and to reduce aggregate separated, dumper is transported to the direct discharging of position in storehouse and put in storage, and should try one's best during warehouse entry guarantee wheel
It is clean, prevent secondary pollution, and there are special personnel to carry out commander's discharging；Closed a position using the MG185 machines of closing a position, if finding
There is local aggregate to concentrate, make all to remove depending on its concrete condition or artificial paving is spilt fine aggregate and handled.Paving thickness be 30~
35cm, and maintaining item band front portion is lower slightly, to reduce automobile discharging drop, reaches the purpose for reducing aggregate separated, after storehouse face is closed a position
It is required that accomplish it is substantially smooth, without notable hollow.
C, roll：Field control after the completion of paving, is rolled using 10m as the construction section that paves by 20t vibrating rollers,
Paving thickness and number of rolling are adjusted according to actual conditions, is notified mixing building to adjust VC values in time according to the situation of rolling.Roll secondary
Number generally 5 times, is first low frequency, rear high frequency, rolling speed is 1.0~1.5km/h.Vibrating roller is against spreading direction from lower to height
Place is rolled, and each position rolling layer is identical, does not leak pressure, and road width both sides suitably increase number of rolling, and number of rolling is generally 5
Time.Must at the uniform velocity be kept straight on when rolling, must not speed change or parking, meet special circumstances when must stop, move backward, the first failure of oscillation of palpus.Applying
Workshop section's termination 4~5m scopes, road roller laterally roll along road surface horizontal slope is appropriate from low to high, slumping crack occur to prevent junction
Or loose phenomenon.
D, concrete is cut：After concrete rolls, any excess concrete beyond highway sideline must be cut away, with the row of guarantee
The design structure sideline in ditch 3 is not destroyed.After the completion for the treatment of that concrete rolls, two sidelines of pavement concrete are drawn, and are marked
Chu is remembered, is cut away concrete unnecessary outside the scope of road surface along by two sidelines using hand-held cutting machine.
E, conserve：Concrete rolls terminate after answer timely covering curing material (gunnysack of wetting, straw mat etc.), after 4~6h
Separated in time watering maintenance, can open to traffic after conserving three days.
F, joint-cutting：After grinding coagulation soil intensity reaches more than the 70% of design strength laterally contracting is sawed every 10m~15m
Seam, slit width 1cm, deep 6cm, and use the pitch horseshoe fat cementation of fissures.
