Description

Subgrade and pavement compacting edge helps plant equipment without formwork erection construction paving
Technical field
The present invention relates to the engineering machinery of road construction, be specifically related to a kind of subgrade and pavement compacting edge and help plant equipment without formwork erection construction paving.
Background technology
As everyone knows, in order to ensure the soundness of road foundation, linear fluency and regularity, all adopt traditional construction method, compacting after namely first paving both at home and abroad at present, pave and compacting time all according to the linear installation form of road foundation designing requirement, template is flitch or channel-section steel, and with steel label gear solid model plate, in case paver, road roller operation time pass crimp, have after some strength until subgrade stability, again template is carried, mobile installation, iterative method forward; There is following problem in traditional construction method:
1, a large amount of templates is needed, wooden long flitch or the channel-section steel of steel,
Flitch is fragile, and channel-section steel cost is high.
2, carrying and the labour intensity installed large, inefficiency, and be difficult to ensure linear, corner is neat.
3, due to formwork erection, the local width of flitch or channel-section steel will take up room, and need stretch out width of subgrade, causes larger waste, strengthens engineering cost.
4, the on-the-spot form removal of workman, vehicle transport, paver pave, road roller rolls, and operating personnel are numerous, on-the-spot chaotic, there is certain potential safety hazard.
To sum up, the conventional construction method that roadbed formwork erection is installed is difficult to meet the requirement of Road to Modernization civilized construction, and waste is comparatively large, increases engineering cost.
Summary of the invention
The object of the invention is to: provide a kind of subgrade and pavement compacting edge to help plant equipment without formwork erection construction paving, without the need to formwork erection gear is solid in advance during construction, help machinery to be with mould at random by paving, ensure the quality of products stable, improve work efficiency, save engineering cost, attractive in appearance smooth and easy, reduction of erection time, Optimizing construction environment.
Technical solution of the present invention is: this paving helps plant equipment to comprise road roller, installs small-sized compact wheel and template in the vibrating wheels side of road roller by elevating mechanism, and overall formation subgrade and pavement compacting edge helps plant equipment without formwork erection construction paving; Described elevating mechanism comprises H-shaped bracing frame, interior slide bar, cylinder and lifting control valve, the top of two longerons of H-shaped bracing frame is fixed on vibrating wheels crossbeam by briquetting, slide bar in installing respectively in two longerons of H-shaped bracing frame, the bottom of interior slide bar connects template
The small-sized compact wheel support of pivot bush unit between two interior slide bars, small-sized compact wheel is installed at the center of small-sized compact wheel support, and the crossbeam central vertical of H-shaped bracing frame installs cylinder, and the bottom of the cylinder rod of cylinder connects template, and cylinder connects lifting control valve.
Wherein, the outside of template connects auxiliary template by coil tension spring.
During construction, first to be paved roadbed or road surface by paver, then by road roller compacted subgrade or road surface; When road roller compacted subgrade or road surface, cylinder action, the decline along with cylinder rod allows interior slide bar decline in the lump with template and small-sized compact wheel; When template is down to shoulder, cylinder rod, to the descending compressive force of template one, also presses down small-sized compact wheel simultaneously; Road roller vibrating wheels forward operational shock operation time, template performs formwork erection function, the synchronous compacted subgrade edge of small-sized compact wheel.
Advantage of the present invention is: 1, road roller vibration steel wheel forward operational shock operation time, template performs formwork erection function, without the need to formwork erection gear is solid in advance, improves work efficiency, saves engineering cost, attractive in appearance smooth and easy, reduction of erection time, Optimizing construction environment; 2, road roller vibration steel wheel forward operational shock operation time, the synchronous compacted subgrade edge of small-sized compact wheel, avoids roadbed side side pressure to be stepped in real time at road roller pressing and damages unfilled corner phenomenon, ensure workmanship.
Accompanying drawing explanation
Fig. 1 is structure diagram of the present invention.
Fig. 2 is the partial side view of Fig. 1.
In figure: 1 vibrating wheels, 2 small-sized compact wheels, 3 templates, 4 H-shaped bracing frames, slide bar in 5,6 cylinders, 7 lifting control valves, 8 vibrating wheels crossbeams, 9 briquettings, 10 small-sized compact wheel supports, 11 coil tension springs, 12 auxiliary templates.
Detailed description of the invention
As shown in Figure 1, this paving helps plant equipment to comprise road roller, installs small-sized compact wheel 2 and template 3 in vibrating wheels 1 side of road roller by elevating mechanism, and overall formation subgrade and pavement compacting edge helps plant equipment without formwork erection construction paving; Described elevating mechanism comprises H-shaped bracing frame 4, interior slide bar 5, cylinder 6 and lifting control valve 7, the top of two longerons of H-shaped bracing frame 4 is fixed on vibrating wheels crossbeam 8 by briquetting 9, slide bar 5 in installing respectively in two longerons of H-shaped bracing frame 4, the bottom of interior slide bar 5 connects template 3, the small-sized compact wheel support 10 of pivot bush unit between two interior slide bars 5, small-sized compact wheel 2 is installed at the center of small-sized compact wheel support 10, the crossbeam central vertical of H-shaped bracing frame 4 installs cylinder 6, the bottom of the cylinder rod of cylinder 6 connects template 3, and cylinder 6 connects lifting control valve 7.
Wherein, the outside of template 3 connects auxiliary template 12 by coil tension spring 11.
During construction, first to be paved roadbed or road surface by paver, then by road roller compacted subgrade or road surface; When road roller compacted subgrade or road surface, cylinder 6 action, the decline along with cylinder rod allows interior slide bar 5 decline in the lump with template 3 and small-sized compact wheel 2; When template 3 is down to shoulder, cylinder rod, to the descending compressive force of template 3 one, presses down small-sized compact wheel 2 simultaneously; Road roller vibrating wheels forward operational shock operation time, template 3 performs formwork erection function, the synchronous compacted subgrade edge of small-sized compact wheel 2.
Below from construction, the engineering cost (direct cost) building two aspect calculated savings, calculate with 1km Class I highway standard section, double width adds up to 4 layers, and template part (shuttering, form removal, transhipment template) unit in charge of construction aspect is spent to be used:
A cement stabilized macadam consumption: long 1000 meters of * thickness, 0.16 meter of * density 2.35*4 layer=18048 ton of the wide 12 meters of * roadbeds of roadbed;
B transports template labour cost: 10 people * 140 yuan/day=1400 yuan;
C transit vehicle rent and fuel oil: 250 yuan/day;
D template loss: 260 yuan/day;
Add up to: 1400 yuan+250 yuan+260 yuan=1910 yuan;
Conversion is spent to be used: calculate labor-material-machine cost, 1910 yuan/2000 tons=0.96 yuan/ton with per day production 2000 tons of cement stabilized macadams;
Reduce expenses, be: 18048 tons * 0.96 yuan/ton=17326 yuan.
The triangular portions of edge that former design is gone to a grassroots level removed, change upper and lower base width into consistent, calculate with 1km Class I highway standard section, double width adds up to 4 layers, Construction unit aspect:
Save cement stabilized macadam expense: thickness 0.32 meter of * 0.32/1.5(side slope 1:1.5) * 2(double width) * (length) 1000 meters=136 cubic metres;
Conversion is reduced expenses: 136 cubic metres * 310 yuan/cubic metres (this unit price is only reference)=42160 yuan.
