Description

Subgrade and pavement is compacted edge and helps mechanical equipment without formwork erection construction paving
Technical field
The present invention relates to the engineering machinery of road construction, and in particular to a kind of subgrade and pavement compacting edge is constructed without formwork erection to be spread Help mechanical equipment.
Background technique
It is well known that robustness, linear fluency and regularity in order to ensure road foundation, all use both at home and abroad at present Traditional construction method first paves and is compacted afterwards, all in accordance with the linear installation template of road foundation design requirement when paving and being compacted, Template is flitch or channel steel, and keeps off solid model plate with steel label, is squeezed and deformed to prevent elapsing when paver, road roller operation, to roadbed Stablize after having some strength, then template is carried, mobile installation, forward iterative method;Traditional construction method is asked there are following Topic:
1, a large amount of template of needs, the channel steel of wooden long flitch or steel,
Flitch is easy to damage, and channel steel is at high cost.
2, the large labor intensity carried and installed, working efficiency is low, and is difficult to ensure that linear, corner is neat.
3, due to formwork erection, the local width of flitch or channel steel wants occupied space, and need to extend outwardly width of subgrade, cause larger Waste increases engineering cost.
4, the demoulding of worker scene, vehicle transport, paver paves, road roller rolls, operator is numerous, and scene is chaotic, There are some potential safety problemss.
To sum up, the conventional construction method of roadbed formwork erection installation is difficult to meet Road to Modernization civilized construction requirement, waste compared with Greatly, engineering cost is increased.
Summary of the invention
It is an object of the invention to: a kind of subgrade and pavement compacting edge is provided without formwork erection construction paving and helps mechanical equipment, is constructed Formwork erection gear is solid in advance by Shi Wuxu, helps mechanical band mould at random by paving, guarantees that quality is stablized, improve work efficiency, save engineering cost, beautiful It is smooth, it shortens the construction period, Optimizing construction environment.
The technical solution of the invention is as follows: it includes road roller that the paving, which helps mechanical equipment, logical in the vibrating wheels side of road roller It crosses elevating mechanism and small-sized compact wheel and template is installed, overall structure subgrade and pavement compacting edge helps machinery to set without formwork erection construction paving It is standby;The elevating mechanism includes that H-shaped support frame, interior slide bar, cylinder and lifting manipulate valve, two stringers of H-shaped support frame Top is fixed on vibrating wheels crossbeam by briquetting, installs interior slide bar, the bottom of interior slide bar in two stringers of H-shaped support frame respectively End connection template,
The center of the small-sized compacting wheel support of pivot bush unit between two interior slide bars, small-sized compacting wheel support is installed by small-sized compacting Wheel, the crossbeam center right angle setting cylinder of H-shaped support frame, the bottom end of the cylinder rod of cylinder connect template, cylinder connection lifting behaviour Vertical valve.
Wherein, the outside of template connects auxiliary template by adjustable spring.
When construction, first paved roadbed or road surface by paver, then by road roller compacted subgrade or road surface;It is compacted in road roller When roadbed or road surface, cylinder movement, as the decline of cylinder rod allows interior slide bar to decline together with template and small-sized compact wheel;When When template is down to shoulder, cylinder rod while also pushing small-sized compact wheel to the compressive force of one downlink of template;In road roller Vibrating wheels when moving forwards vibration service, template executes formwork erection function, the synchronous compacted subgrade edge of small-sized compact wheel.
The invention has the advantages that 1, when the vibration steel wheel of road roller moves forwards vibration service, template execute formwork erection function Can, it is solid without the gear of formwork erection in advance, work efficiency is improved, engineering cost is saved, it is beautiful smooth, it shortens the construction period, Optimizing construction environment;2, exist When the vibration steel wheel of road roller moves forwards vibration service, the synchronous compacted subgrade edge of small-sized compact wheel avoids roadbed side from existing Side pressure is stepped on damage unfilled corner phenomenon in real time by road roller pressing, guarantees construction quality.
Detailed description of the invention
Fig. 1 is structure diagram of the 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 support frames, slide bar in 5,6 cylinders, 7 lifting manipulation valves, 8 vibrating wheels crossbeams, 9 briquettings, 10 small-sized compacting wheel supports, 11 adjustable springs, 12 auxiliary templates.
Specific embodiment
As shown in Figure 1, it includes road roller that the paving, which helps mechanical equipment, pacified in 1 side of vibrating wheels of road roller by elevating mechanism Small-sized compact wheel 2 and template 3 are filled, overall structure subgrade and pavement compacting edge helps mechanical equipment without formwork erection construction paving;The liter Descending mechanism includes that H-shaped support frame 4, interior slide bar 5, cylinder 6 and lifting manipulation valve 7, the top of two stringers of H-shaped support frame 4 are logical It crosses briquetting 9 to be fixed on vibrating wheels crossbeam 8, interior slide bar 5, the bottom of interior slide bar 5 is installed respectively in two stringers of H-shaped support frame 4 End connection template 3, the small-sized compacting wheel support 10 of pivot bush unit between two interior slide bars 5 are felt at ease in small-sized compacting wheel support 10 Small-sized compact wheel 2 is filled, the bottom end of the crossbeam center right angle setting cylinder 6 of H-shaped support frame 4, the cylinder rod of cylinder 6 connects template 3, The connection lifting manipulation valve 7 of cylinder 6.
Wherein, the outside of template 3 connects auxiliary template 12 by adjustable spring 11.
When construction, first paved roadbed or road surface by paver, then by road roller compacted subgrade or road surface;It is compacted in road roller When roadbed or road surface, cylinder 6 is acted, with the decline of cylinder rod allow interior slide bar 5 with template 3 and small-sized compact wheel 2 together under Drop;When template 3 is down to shoulder, cylinder rod while pushing small-sized compact wheel 2 to the compressive force of 3 one downlinks of template;? When the vibrating wheels of road roller move forwards vibration service, template 3 executes formwork erection function, the synchronous compacted subgrade side of small-sized compact wheel 2 Edge.
Below from construction, construction two in terms of calculated savings engineering cost (direct cost), with 1km Class I highway standard Section calculation, double width is 4 layers total, spent in terms of template part (shuttering, form removal, transhipment template) unit in charge of construction to use:
A cement stabilized macadam dosage: long 1000 meters of 2.35*4 layers of the * density of 0.16 meter of * thickness of the wide 12 meters of * roadbeds of roadbed= 18048 tons;
B transports template labour cost: 140 yuan/day=1400 yuan 10 people *;
C transit vehicle rent and fuel oil: 250 yuan/day;
D template loss: 260 yuan/day;
It is total: 1400 yuan+250 yuan+260 yuan=1910 yuan;
Conversion is spent to be used: labor-material-machine costs are calculated with per day 2000 tons of cement stabilized macadams of production, 1910 yuan/2000 Ton=0.96 yuan/ton;
Saving expense is then are as follows: 18048 tons * 0.96 yuan/ton=17326 yuan.
The triangular portions for edge of going to a grassroots level in former design are removed, it is consistent to be changed to base width up and down, with 1km Class I highway Standard section calculates, and double width is 4 layers total, in terms of construction unit:
Save cement stabilized macadam expense: 0.32 meter of * 0.32/1.5(side slope 1:1.5 of thickness) * 2(double width) * (length) 1000 meters=136 cubic metres;
Conversion saving expense: 136 cubic metres * 310 yuan/cubic metres (this unit price is only to refer to)=42160 yuan.
