Description
Technical field
The present invention is a kind of neo-epoxy resin footbridge cement concrete bridge deck thin layer paving structure, belongs to road engineering
Technical field.
Background technology
In recent years, flourishing with Modern Traffic cause, Large Span Bridges are on the increase, deck paving technology conduct
Large Span Bridges build one of key technology and are more taken seriously, and deck paving is in bridge system in vitally
Position, final molding effect and the durability and economic benefit of the be open to traffic level of comfort, bridge structure that are travelled with rear vehicle cease
Manner of breathing closes.Traditional paving structure uses for reference the experience of road engineering, often prevents cracking of mating formation using larger structural thickness, and
Still there is the problem of a large amount of earlier period damages in pave-load layer, however only considers deck paving as dead weight when bridge structure design,
The influence of pave-load layer is not considered in structural stress analysis, increasing that especially traffic axis carries in recent years and traffic flow surge
Cause bridge overall structure and bridge floor partial structurtes that a large amount of disease has occurred, even result in some catastrophic destructions,
For which part because except structure design or construction problem, an important part is caused because of the early damage of bridge deck pavement
Objectionable impurities accelerates the corrosion and destruction of bridge deck concrete and internal reinforcing bar in moisture intrusion bridge structure, finally so that whole
Body structural bearing capacity is greatly reduced.
The status of footbridge is increasingly taken seriously in the also planning in gradual large and medium-sized city each at home and abroad at present,
And the introducing of pave-load layer will resist moisture attacks, oxidation and ultraviolet ray ageing effect etc. so that floorings are not subjected to surface
Damage, but the structure function missing of bridge deck pavement is often at the bottleneck of constraint walking Graft patency, and state's interior thin layer epoxy
Pavement material is promoted the use of, still primary limitation indoors terrace mat formation, reparation and U.S. of cement concrete bridge deck and road surface
The more demanding colored road surface of the property seen is mated formation, and is also small part application for municipal overpass and accommodation road.Currently
Footbridge mainly uses asphalt concrete material to carry out deck paving, and from the point of view of the floor system of destruction, bridge surface mangle is light
It is upper layer bituminous concrete cracking, gathers around packet, the floorings of severe one lower part has all been corroded or have been crushed.Often will appear due to
Gluing layer intensity is relatively low, and the high-temperature stability of material is poor and leads to temperature deformation, causes delamination and breaks down；It is impervious
It is poor, pave-load layer Water Damage caused by the invasion of moisture and bridge floor etching problem；There is bridge caused by pave-load layer dead weight is larger
Construction pollution, traffic noise and the running maintenance solid waste that effect depression of bearing force problem and traditional pavement technique are brought
Cause environmental issue etc..Due to thin layer epoxy material at home by large scale system for carry out the case of deck paving compared with
Few, the especially application in concrete pavement is more rarely reported, and domestic opposite shortage is for thin layer epoxy deck paving system
System theory summary, about epoxy material, for deck paving, there has been no more complete system engineering application studies to summarize, and does not also have
There is the systematicness of the complete specifically process program of epoxy Surfacing Construction, technical standard and Engineering Quality Control system total
Knot.
As China's urban modernization builds raising of the fast-developing and people to green low-carbon environmental requirement, increasingly
More municipal overpasses and landscape channel input are built, and the premature damage of traditional rubber pave-load layer structure restricts significantly
The development of economic infrastructure construction.How by the advanced material technology phase of domestic ripe bridge tunnel Pavement design and foreign countries
In conjunction with, it solves traditional overpass and mats formation the problems of body, and be further applied to Large Span Bridges deck paving, it is right
Thin layer epoxy deck paving carries out system research and summarizes just to seem particularly important.The Dow Chemical company that the present invention uses
Polyurethane modified epoxy resin leads in field of bridge deck pavement, the application to engineering practice thousands of after 40 years and technological accumulation
It crosses polyurethane to be modified epoxy resin, greatly overcomes the brittleness of ordinary epoxy resin material and lacking for weatherability difference
It falls into, and small, light weight, anti-corrosion are anti-with thickness for this kind of neo-epoxy resin footbridge cement concrete bridge deck thin layer paving structure
The good feature of oozing property can effectively mitigate bridge heavy burden, reduce the pressure of bridge structure, greatly extend bridge service life.
