Abstract
The utility model discloses a steel bridge deck paving structure, which is applicable to the field of a paving technology for road surfaces in traffic engineering. The steel bridge deck paving structure comprises a thermal spraying metal layer adhered on a bridge deck steel plate base body; the thermal spraying metal layer is 100-300 Mu m in thickness; a nanometer modified epoxy primer sealing layer is adhered on the thermal spraying metal layer; and an epoxy asphalt layer is arranged on the nanometer modified epoxy primer sealing layer. The steel bridge deck paving structure has the advantages of simple structure, prominent and reliable performances, is convenient for construction and has wide practicability.
Description
Technical field
This use is novel to relate to a kind of paving steel bridge deck structure, is particularly useful for traffic engineering pavement of road pavement technique field and uses.
Background technology
Continuous expansion along with China's rapid economic development and transport development project scale, the large-scale steel structure bridge engineering is increasing, the application technology of striding the footpath orthotropic steel bridge deck has greatly obtained rapid popularization, and the research of steel bridge face protection pavement technique has just become the focus of domestic and international research.
Steel bridge face protection pavement technique mainly comprises two parts, bridge floor guard technology and paving technology.The bridge floor guard technology mainly contains paint coatings protection and metal coating protection two big classes, and the paint coatings guard technology is after the steel bridge face is carried out surfacing, application inorganic zinc coating or epoxy zinc-enriched paint; The metal coating protection then is that the spraying spelter coating formed after the steel bridge face was carried out surfacing, because the layer of mating formation contains the bottom waterproofing course, bridge floor hot spray painted zinc coating surface does not carry out conventional sealing to be handled.Steel bridge face paving technology is according to the steel bridge face structure and the operation characteristic holder requirement that is open to traffic, the main epoxy asphalt concrete layer of mating formation that adopts, substratum for waterproofing (also claiming tack coat), the epoxy asphalt concrete that generally comprises bottom lower floor, tack coat, the epoxy asphalt concrete upper strata of mating formation of mating formation.
Since steel bridge face protection pavement technique is used, there are problems always, after being open to traffic as road, bridge deck pavement can occur rut, cracking successively, pass, gathers around diseases such as bag, also still can not deal with problems though in time obtain maintenance in time, the bituminous mixture of mating formation on the steel bridge face becomes a global problem.
CN200978385 adopts conventional anticorrosive coating layer with the mode that double-deck epoxy asphalt concrete layer combines the steel bridge face to be mated formation, and facts have proved that effect is unsatisfactory; CN101045995 then proposes a kind of hot spraying guard technology of steel box girder bridge face; at surface of steel plate hot spraying nickel-alloy coating; be equipped with asphalt concrete pavement layer again; overcoat is realized combining preferably with the steel plate and the layer of mating formation; obtained certain effect; but this design lacks the protection of metal coating is handled; only rely on mat formation layer bonding of lower floor's waterproofing course and a protection; and do not consider and mat formation layer in case be in operation appearance cracking breakage or crimp; surface gathered water will infiltrate the hot spraying metal level; thereby cause the metal level corrosion to destroy ply adhesion, further cause pavement cracking; pass; gather around the formation of bag problem.
Summary of the invention
The purpose of this utility model is the deficiency that overcomes in the prior art, provides a kind of simple in structure, and corrosion resistance is good, the paving steel bridge deck structure of long service life
For achieving the above object, paving steel bridge deck structure of the present utility model comprises attached to the hot spraying metal level on the bridge floor steel matrix, the bituminous epoxy layer, described hot spraying metal level is the almag hot spraying metal level that contains 3% magnesium metal, or contain the rare-earth-Al-Mg alloy hot spraying metal level of 0.01% two or more rare earth element, the hot spraying metal layer thickness is 100-300 μ m, be attached with nanometer modified epoxy priming paint confining bed on the hot spraying metal level, have the bituminous epoxy layer on the nanometer modified epoxy priming paint confining bed.
Described almag hot spraying metal level optimum thickness is 150-200 μ m, and described rare-earth-Al-Mg alloy hot spraying metal level optimum thickness is 100-200 μ m, and described nanometer modified epoxy priming paint confining bed thickness is 1-50 μ m.
Beneficial effect: paving steel bridge deck structure of the present utility model; overcoat adopts the hot spraying metal level structure that combines with the nano modification confining bed; whole protection layer combination property reliable and stable; when the layer breakage of mating formation; the generation that can effectively organize corrosion through the metal coating of osmotic protection when surface gathered water infiltrates with spread; the reliable attachment of assurance metal coating this moment and the layer of mating formation; the effectiveness of the nano modification confining bed bottom waterproofing course of layer that significantly is better than mating formation in addition; the utilization structure that therefore also can save waterproofing course as required is simple; easy construction; performance is outstanding reliable, has practicality widely.
