Description
Technical field
The present invention relates to highway road surface technical field of construction, especially a kind of highway road surface construction transverse joint processing
Device, in being constructed for highway road surface, because construction organization, paragraph are divided, working face conversion or other reasonses are interrupted and applied
When more than work 2h needs to set construction transverse joint, the device that transverse joint is set can quickly, accurately, specification be realized.
Background technology
Highway road surface or underlayment(Note:Only carried in follow-up discussion " basic unit ", but it is actual comprising " basic unit " and " bottom
Basic unit ")In construction, because construction organization, paragraph are divided, construction more than 2h is interrupted in working face conversion or other reasonses, it is necessary to
Construction transverse joint is set to specification, is connected with facilitating to smooth out during subsequent construction, ensures that each structure sheaf flatness in road surface and road surface are whole
Body road-ability.At present, road base layer construction transverse joint sets conventional method to have three kinds:
First method:" paver is paved and rolled " construction transverse joint set-up mode.When the normal section of highway is constructed, generally spread out
Road roller directly coordinates roller-compaction after paving machine paves.Now, according to《Highway road surface construction technology detailed rules and regulations》
(JTG/T F20-2015)5.4.22 the setting of construction transverse joint should be met the following requirements:
(1)It is artificial that the suitable compound of end moisture content is neat, put two lumps of wood against compound end, the height of the lumps of wood with
The compacted depth of compound is identical, compound of the leveling against the lumps of wood;
(2)Opposite side gravel or rubble the backfill about 3m length of the lumps of wood, its height should be higher by lumps of wood 2-3cm, and grinding compacting;
(3)Before paved mixture again, gravel or rubble and the lumps of wood should be removed, and sub-layer top surface is cleaned up;
(4)Paver returns to the end of compacted lift, restarts paved mixture.
The drawbacks of this method is:(1)The lumps of wood is easily rolled destruction, constantly more renews lumps of wood cumulative cost high;(2)Adopt
With gravel or rubble backfill about 3m length, it is necessary to which 4-8m3 gravels or rubble, transport can only use small-size dump truck, cost is high;(3)
Gravel or rubble are rooted out in scene, and because side is measured, small, working face is small can not to realize mechanization.So, this partial gravel or rubble are often
By waste disposal, general abandoned well is piled up in slope of highway, causes serious waste and the environmental disruption of road domain.(4)Which is made
The industry time is long, using artificial more, and efficiency is low, is not matched that with the demand for development of extensive and comprehensive mechanized construction.
Second method:According to " paver is paved and rolled " form of construction work, the interruption that paves is more than 2h, and not by above-mentioned
, should be by near paver and the compound without compacting is rooted out below, and will grind when first way sets construction transverse joint
Densification reality and elevation and the satisfactory end of flatness scrape out section vertical with Lu Zhizheng line and vertically downward, then spread out
The new compound of paving.Or minitype cutting machine joint-cutting is used, then manually remove sloped transition section.
This method is widely adopted at present.But the drawbacks of this method is present is:(1)Configuration cuts machine, generator are needed
Want certain cost;(2)Diesel Generator Noise is big, uses fuel contamination air;(3)Cutting machine cools down blade, meeting using flowing water
Mud contamination construction transverse joint is produced, the inherent quality of new and old compound linking is influenceed;(4)At least need two people's compounding practices, people
Work cost is high, potential security risk in operating process;(5)Basic unit's material that plan after cutting is discarded is small due to side's small, working face of amount
Mechanization can not be realized.So, this part basic unit material often presses waste disposal, and general abandoned well is piled up in slope of highway, caused
Serious waste and the environmental disruption of road domain;(6)Which activity duration is long, and efficiency is low, with extensive and comprehensive mechanized construction
Demand for development do not match that.
The third method:" Manual is with rolling " construction transverse joint processing mode.For road surface corner part, widen transition
The pavers such as section can not the direct position such as narrow ring road in place, can be paved using bull-dozer, the manual type stand of land leveller leveling
Spread and roller-compaction synchronous with main line.Now, according to《Highway road surface construction technology detailed rules and regulations》(JTG/T F20-2015)
5.5.19 the setting of construction transverse joint should be met the following requirements:
(1)In the stabilized with inorganic binder material layer end rolled, digging one traverses the width about 300mm's of making layer overall with
Groove, until sub-layer top surface.Form section with the median perpendicular on road and vertically downward, and put two and compacted depth uniform thickness,
The lumps of wood top patch vertical plane of a length of overall with half, as shown in Figure 1.
(2)The material dug out with original backfills remainder in groove;
(3)The lumps of wood is removed after second day adjacent job step mix, is backfilled with compound;
(4)Fail a bit of of mix close to the lumps of wood, answer artificial supplementation mix;
(5)During leveling, the stabilizing material of seam crossing should complete section and be higher by about 50mm;
(6)In new compound roller compaction process, seam amendment should be smoothed out.
The drawbacks of this method is:(1)The lumps of wood is easily rolled destruction, constantly more renews lumps of wood cumulative cost high;(2)People
The drawbacks of work grooving or cutting machine are cut is identical with the second way;(3)The mode of plain earthen backfill and first method gravel
Stone or rubble backfill drawback are approximate;(4)The waste material that scene is rooted out typically is piled up in slope of highway, causes serious waste and road domain
Environmental disruption.
