Description
Technical field
The present invention relates to a kind of bridge floor paving block and the processing method of this paving block, the bridge of this paving block that the invention still further relates to mat formation
Beam.
Background technology
Steel bridge is conducive to alleviating dead load and playing the characteristic of space structure, is the version of Large Span Bridges first-selection.But
Deck paving is all proposed strictly by the features such as steel bridge deck is smooth, pliable and tough, local deformation is big, dynamic characteristics is complicated, thermal capacitance is little
Requirement.Existing paving steel bridge deck no matter cast asphalt concrete (GA), bitumastic concrete (MA), modified pitch
(SMA), epoxy resin asphalt (EA) diseases such as high temperature rut, laterally passage, cracking occur the most too early, these diseases both with steel bridge
Face disadvantageous use condition of mating formation about also there being direct relation with the traffic of China, but it is crucial that the various structures mated formation
GA, MA, SMA, EA can not meet paving steel bridge deck functional requirement: the best tired anti-cracking performance, excellent high stability
Energy, perfect guarded drainage performance, the good Coating combination performance following good with steel plate deformed, good flatness with
Antiskid performance, the least suitable thickness (alleviating dead load).
According to incompletely statistics, current domestic Long span highway bridge has completed paving steel bridge deck area only 2,000,000 square meter.Nearly 20
Research is mated formation in year Steel Bridges in China face and practice did not stopped the most always.But, paving steel bridge deck problem is the most not yet in effect up to now
Solve.From technological layer, steel box-girder is large thin-wall space structure, under temperature and load action, steel box-girder can extend,
Shorten, bending, locally downwarp, torsion etc. deform.Deck paving requires have the ability following steel box-girder cooperative transformation together.Separately
Outer one side, deck paving directly takes on wheel load and rolls, and deck paving needs to resist the local change that wheel load produces
Shape, requires that paving steel bridge deck keeps outward appearance smooth-going, it is simple to driving simultaneously.This conflicting demand just determines steel deck paving
Dress engineering complexity.In addition the heavy-duty vehicle phenomenon that highway in China generally exists, this exacerbates the complexity of contradiction undoubtedly.
Bridge deck pavement structure and material and selection, be not only the difficult point in highway engineering in China construction for many years and hot spot technology asked
Topic, is also a difficult problem the most unsolved in the world.
The paving steel bridge deck of countries in the world the most all uses bituminous concrete system at present.Bridge deck pavement structure is main
There are following four big classes: 1. German, Japan is cast asphalt concrete GA (Guss Asphalt) structure of representative, typically Germany
The thickness of cast asphalt concrete is 2 × 35mm, and Japan's 35mm cast asphalt concrete+30mm modification dense bitumen mixes
Solidifying soil；Bitumastic concrete MA (Mstic Asphalt) structure with Britain as representative (is the most also cast asphalt
Concrete, simply pavement thickness and technique are different with Japan etc.), general 38mm pouring asphalt concrete, it mainly lacks
Point is: poor high temperature stability, is easily formed rut；Construction needs a series of special equipments, and construction organization is complex；Mix during construction
The temperature closing material is the highest, reaches more than 240 DEG C, and the impact on bridge can not be ignored.Cast-type steel deck paving packing technique is suitable for
In the countries and regions that summer temp is the highest, such as some countries such as Germany, Britain, Northern Europe, cast-type steel deck paving packing technique
The most relatively broad in the application of Japan.；2. the modified asphalt SMA structure (Stone that the state such as Germany and Japan uses in the recent period
Mastic Asphalt), modified asphalt SMA major defect: modified asphalt SMA is widely used in pavement structure, but pass through
To the steel bridge application survey that is completed, modified asphalt SMA is mated formation at steel bridge and is applied effect unsatisfactory, and road surface is opened and shortly can be gone out
Bag, passage, bellding, local fatigue crack are gathered around in rut, local that existing degree is different；Double-deck SMA applies more at home in early days, warp
Crossing use for a long time, the deck paving of some bridges occurs in that heavy damage, various failure modes have showed.Owing to adopting
The best by the SMA material crack resistance of SBS pitch, mat formation one of modal disease so cracking is double-deck SMA, bridge floor is also simultaneously
There will be the diseases such as rut, pit, passage.3. epoxy resin asphalt EA (Epoxy asphalt) coagulation with the U.S. as representative
Soil structure, total thickness 32-76mm epoxy asphalt concrete (EA), major defect is: bituminous epoxy price is higher, the many quilts of key technology
External large enterprises control；The preparing process of epoxy asphalt mixture is more complicated；In epoxy asphalt mixture construction to the time and
Temperature requirement is very strict, and construction environment is required harshness, and difficulty of construction is big.Epoxy asphalt pavement curing time is long, repairs difficulty
Degree is big, occurs that the restorative procedure after damaging also does not has currently for bituminous epoxy；Epoxy asphalt pavement work rear surface is smooth, macroscopic view
Construction depth is little, and particularly rainy day travel safety is poor.The subject matter that epoxy asphalt pavement occurs is Construction control, construction
Controlling is the most sternly the main cause being damaged of mating formation.Its pliability is poor relative to for asphalt material, and deck paving easily goes out
The now disease such as cracking；Owing to epoxy asphalt pavement layer is waterproof, during construction, the moisture of internal residual is easily caused pave-load layer drum
Bag disease, as the most effectively processed, can be further developed into as pit.The reparation of epoxy asphalt pavement is the best
Way, after milling, re-pave needs long health, very big to traffic impact, and repairing construction often to be yielded to hand over
Logical pressure, the effect that final impact is repaired.
Steel bridge deck pavement is typically made up of antirust coat, tack coat, asphalt mixture paving course, and direct making is in steel box-girder
On top board, gross thickness is between 35-80mm.Due to the use condition of steel box girder bridge floor paving, construction technology, quality control with
The particularity required, intensity, anti-fatigue performance, anti-rut behavior, anti-shear performance and compatibility of deformation etc. to it all have
Higher requirement, China the most not yet forms universal effective paving steel bridge deck design theory and method.
At present, the most the most frequently used, be also think in the industry effect best have three kinds of steel bridge paving structures.Structure one:
Bilayer modified SMA paving steel bridge deck of domestic early stage is frequently with this kind of structure.Its disease mainly has cracking, pit, rut and passage.
Structure two: pouring asphalt concrete (GA)+high-elastic SMA.Owing to upper strata have employed high-elastic asphalt SMA, Damage Types is with double-deck
SMA is more similar.Structure three: double-deck U.S. epoxy asphalt concrete.From 2008 so far, domestic many employing U.S. epoxy drip
The Steel Bridge Deck of blue or green concrete pavement technology also begins to occur in that disease and defect, bituminous epoxy paving steel bridge deck Common Diseases have:
Bulge, cracking, pit etc..Its problem also becomes increasingly conspicuous, and the time does not appears to one and generally acknowledges feasible pavement technique scheme.By
In the use condition of steel bridge deck pavement, construction technology, the particularity of quality control and requirement, its intensity, anti-fatigue performance,
The use requirement that anti-rut behavior, anti-shear performance, anti-seismic performance and compatibility of deformation etc. are all different from roadbed.
Up to the present, the development of domestic paving steel bridge deck has been subjected to three phases.From 1997 to 2002 years, with tiger
Door bridge is representative, positive Introduced From Abroad advanced person's pavement technique, and the technology that period introduces and promotes has: double-deck SMA concrete, English
The technology such as state's cast asphalt concrete and U.S.'s bilayer epoxy asphalt concrete, but all create delamination passage disease.From
2002 to 2008, first two technology there is a problem in engineer applied, the U.S.'s epoxy drip with Nanjing Er Qiao as representative
Blue or green concrete technology starts application.From 2008 so far, domestic many steel using U.S.'s epoxy asphalt concrete pavement technique
Bridge floor also begins to occur in that disease and defect, in the industry U.S.'s epoxy asphalt concrete pavement technique is also lost confidence, steel bridge
Face problem of mating formation becomes increasingly conspicuous, and the time does not appears to one and generally acknowledges feasible pavement technique scheme.As can be seen here, China is built
The bridge asphalt pavement service condition of big-span steel bridge is not ideal, the domestic successful experience also lacking paving steel bridge deck.Additionally,
External paving steel bridge deck service life is also never greater than 30 years.
