Description
Technical field
The present invention relates to the construction method of the grand sound warning tape in a kind of road shoulder place, relate in particular to a kind of method that adopts the heat mode that rolls to carry out grand sound warning tape construction on curb.
Background technology
Now on the curb of speedway both sides, generally be provided with grand sound warning tape, grand sound warning tape is comprised of groove or projection, it is by vehicle tyre and groove or the protruding larger sound and the vibrations that rub and send, thereby remind driver's vehicle to be positioned at road shoulder, departed from normal travel route.Grand sound warning tape is now generally to adopt cold milling formula, and its construction noise is large, and equipment cost is high, easy to wear, and construction produces a large amount of waste materials, can road pavement damage simultaneously.Correlation technique content of the present invention has no relevant report.
Summary of the invention
The object of the invention is to propose a kind of short construction period, can save a large amount of human and material resources, road pavement is without the grand sound warning tape of the hot compaction type curb construction method of destroying simultaneously.
The technical solution adopted in the present invention is: the grand sound warning tape of hot compaction type curb construction method comprises cleaning, adjusts, paves, bituminous mixture rolls rolls five steps with grand sound warning tape: (1), cleaning: surface layer under asphalt concrete is cleaned; (2), adjust: before paving, first will adjust paver, paver screed is adjusted into half-amplitude duration, and adjust and automatically make leveling device, before paving, screed be heated; (3), pave: the mode that paver adopts half range to pave paves; (4), bituminous mixture rolls: after bituminous mixture completes and paves, carry out immediately compacting operation; (5), grand sound warning tape rolls: select rubber-tyred roller, equidistant in the rigidity circumference of hub of its front side, interval welding round steel pipe, rubber-tyred roller rear side is rubber tire, driving this rubber-tyred roller travels along the graticule that is indicated in curb both sides, can be in graticule outside, road edge line inner side rolls out downward groove, forms grand sound warning tape.
The invention has the beneficial effects as follows: disposal molding, shape remains intact, and does not destroy pavement strength.The repacking space of equipment is sufficient, and rubber tire after front steel wheel does not destroy the concave surface of moulding.
accompanying drawing explanation:specific embodiment of the invention method and relevant device are provided by the following drawings:
Fig. 1 is the road top view after grand sound warning tape construction;
Fig. 2 is rubber-tyred roller wheel hub structure schematic diagram.
Legend: 1. center line of road; 2. graticule; 3. grand sound warning tape; 4. road edge line; 5. round steel pipe; 6. wheel hub.
The specific embodiment
Embodiment: the present invention includes cleaning, adjust, pave, bituminous mixture rolls rolls five steps with grand sound warning tape:
1, cleaning: surface layer under asphalt concrete is carried out to hand sweeping, guarantee lower surface layer no-sundries, float stone, and measure setting-out, and report supervising engineer's verification.
2, adjust: paver can adopt ABG423 paver, before paving, first will adjust paver, reach the requirement of design horizontal wall inscription, paver screed is adjusted into half-amplitude duration, and adjusts and automatically make leveling device.Before paving, by screed heating, according to paver feed capacity, determine that the paver speed of paving paves, the temperature that paves is controlled between 120-150 ℃.
Horizontal wall inscription is to take road Cross Section as visual angle, the gradient of road-center or end to end.Horizontal wall inscription meets implements PDD requirement.
The paver speed of travel should be controlled at 1 ~ 1.5m/min according to bituminous concrete mixing building deliverability and supporting the compacted machine ability and quantity, and remains at the uniform velocity and advance, and must not neglect to neglect soon slowly, without special circumstances, must not stop over.Paver uses suitable vibrate frequency and vibration frequency, to guarantee enough initial degree of compaction.
3, pave: paver adopts the mode that half range paves to pave, paver should be slowly, evenly, continuously pave, and in paving process, can not occur manifesting of conversion rate.
In paving process, paver both sides feeding screw should ceaselessly at the uniform velocity rotate, and makes both sides bituminous mixture height remain 2/3 height of screed, makes full section that segregation phenomenon not occur.In paving process, establish special messenger and detect pave temperature, virtual resurfacing thickness.
4, bituminous mixture rolls: after bituminous mixture completes and paves, carry out immediately compacting operation, roll temperature and be controlled at 100-145 ℃, compacting is divided into first pressing, multiple pressure, final pressure three phases.According to the characteristic of the productivity ratio of the paving thickness of bituminous mixture, paver and bituminous mixture, select pneumatic-tired rollers to coordinate and roll with BW dual-steel wheel road roller.
(1) first pressing: first pressing mainly improves the initial density of bituminous mixture, plays stabilization, according to facts have proved, under higher temperature, rolls and can receive good consolidation effect.Therefore at compound, do not produce after paving in the situations such as passing, shattered crack as far as possible and carry out under higher temperature.First pressing adopts the two steel wheels of 13t road machine static pressure 4 times, and rolling speed is controlled at 3-5Km/ hour, the order of first pressing: road roller is by curb one side pressure Xiang Lu center, or is rolled to high side by downside.Trailing wheel should overlapping 1/3～1/2 take turns wide.While rolling by driving wheel towards the direction that paves, prevent that compound from passing or producing and gather around bag.
First pressing should reduce spraying as far as possible, prevents that bituminous mixture cooling is too fast.
(2) multiple pressure: after bituminous concrete first pressing completes, carry out immediately multiple pressure, guarantee to press again temperature to be not less than 110 ℃.Multiple pressure adopts 1 13t dual-steel wheel road roller vibroroller cmpacting, and number of rolling is 4 times.Rolling speed is controlled at 3-5km/h.
(3) final pressure: final pressure adopts 1 16 tons of pneumatic-tired rollers and 1 13t dual-steel wheel road roller to roll, and first adopts rubber-tyred roller to roll 2 times, and tire pressure is not less than 0.7Mpa, trailing wheel should overlapping 1/3～1/2 take turns wide.Finally adopt 13t dual-steel wheel road roller to roll 2 times and receive light, do not shake, roll without till obvious wheelmark.Final pressure speed is controlled at 3-5km/h.The order of final pressure is identical with first pressing, and rolling finishing temperature should be lower than 80 ℃.
5, grand sound warning tape rolls: as shown in Figure 1, 2, select YZ12 rubber-tyred roller, equidistant on rigidity wheel hub 6 circumference of its front side, interval welding round steel pipe 5.Rubber-tyred roller rear side is rubber tire.Drive this rubber-tyred roller and travel along the graticule 2 that is indicated in curb both sides, can be in graticule 2 outsides, road edge line 4 inner sides roll out downward groove, and each flute pitch is equal, and shape is identical, forms grand sound warning tape 3.Graticule 2 delimited in road both sides, and its delimitation standard is carried out by standard GB/T 5768-1999.
The present invention compares the grand sound warning tape construction method of traditional cold milling formula, and its construction noise is little, and speed of application is fast, and machinery refitment is convenient, and cost is lower.In work progress, substantially without rubbish, produce, and road pavement is without destruction.
