Background technology
Design that steel structure bridge is rich in creativeness with it and extraordinary refined moulding are bursted forth strange light extraordinary splendor in world's bridge construction history, mating formation also along with the unremitting effort of builder with pursue and obtain remarkable achievement of Steel Bridge Deck.For big-span steel bridge, bridge asphalt pavement layer directly influences the safety of driving, comfortableness, bridge durability as the important component part of bridge vehicle-driving, its quality.Therefore, except the intensity to bridge asphalt pavement layer.Deformation stability, fatigability etc. all have outside higher requirement, also require that it meets the particular/special requirements such as lightweight, high-adhesion, impermeability in serviceability, the asphalt concrete that past steel bridge uses is mated formation, or uses modified pitch to mat formation and still can not meet its needs.
Summary of the invention
Invention provides a kind of Steel Bridge Deck epoxy asphalt concrete construction, solve above-mentioned produced problem.
The present invention adopts the technical scheme that: a kind of Steel Bridge Deck epoxy asphalt concrete construction, comprises the following steps: step S101, and bridge floor cleaning processes；Step S102, bridge floor impeller blasting；Step S103, spray painting operation；Step S104, connects batch position and processes；Step S105, epoxy asphalt concrete paves；Step S106, epoxy asphalt concrete rolls；Step S107, epoxy asphalt concrete maintenance.
Described bridge floor cleaning processes, and before operation, first cleans surface of steel plate comprehensively with the instrument such as giant, hairbrush, rinses, the place dispersant work local cleaning that greasy dirt is serious, then wide scouring；Treat that bridge surface armor plate is dried, surface of steel plate has the welding thing that construction overlap, the crator etc. of protrusion remain on steel plate, and removing of polishing one by one with electric grinding machine, in bruting process, being careful not to too much erosion floorings, the steel plate after polishing should ensure that the smooth, clean of surface.
Described bridge floor impeller blasting, each width work strip to have the lap width of 50～100mm, and when the fineness after ball blast reaches more than 2.5 grades, roughness, in the range of 60～80 m, can carry out next procedure construction；The surface of steel plate of impeller blasting must blow off surface floating dust by the compressed air being dried, clean in time; and in 4h, spray epoxy zinc rich primer; fail timely operation for some reason, suitable protective measure will be taked, to stop the moisture in air and other materials reoxidation to steel plate.
Described spray painting operation, epoxy zinc rich primer to mix the most in proportion and to join, if special messenger detects wet-film thickness with wet film card and calibrator, accomplish coating be evenly distributed, thickness moderate；Testing oneself continuously wet-film thickness with wet film card in construction, wet-film thickness should be 100～140 m, to obtain the build required.
The described batch position of connecing processes, and construction operation every day region to be left and certain to spray after the 200mm width layer of paint sand papering reserved being fallen hair stubble when connecing the operation next time of batch position again, is still to ensure the cleaning of the scope of operation before spraying.
Described epoxy asphalt concrete paves, S2100 or S1800 paver is used to pave, paver automaticity is high, simple to operation, the paver 1h before work that paves every day preheats, and controls preheating temperature between 110～121 DEG C, after the first width paves, has been compacted, next width utilizes previous width to make datum level when paving, before the second width paves, will be cut by the longitudinal joint being connected with the first width after bituminous epoxy bonding oil is smeared on inclined-plane at 45 ° and carry out the construction that paves again.
Described epoxy asphalt concrete rolls, and rolls and carries out immediately following paver, rolls all static pressure, if special messenger is responsible for keeping an eye on compacting work, it is ensured that final pressure finishing temperature is not less than 55 DEG C.
Described epoxy asphalt concrete maintenance, uses and stands maintenance method, and curing period must not < 45d forbids all vehicle pass-throughs during this period.
The advantage of the present invention is: epoxy asphalt mixture has the advantage that intensity is high, rigidity is big, during high temperature, anti-plasticity and permanent deformation are strong, crack resistance at low-temperature is good, there is fabulous anti-fatigue performance, it it is 10～30 times of asphalt concrete fatigue life, and its construction technology is simple and convenient, and the cycle is short, the impact on road traffic is little.
Accompanying drawing explanation
Accompanying drawing is Steel Bridge Deck epoxy asphalt concrete construction process figure.
Detailed description of the invention
It is described further below in conjunction with construction process figure.
As shown in the figure, a kind of Steel Bridge Deck epoxy asphalt concrete construction, comprise the following steps: step S101, bridge floor cleaning processes, before operation, first surface of steel plate is cleaned comprehensively with the instrument such as giant, hairbrush, rinses, the place dispersant work local cleaning that greasy dirt is serious, then wide scouring；Treat that bridge surface armor plate is dried, surface of steel plate has the welding thing that construction overlap, the crator etc. of protrusion remain on steel plate, and removing of polishing one by one with electric grinding machine, in bruting process, being careful not to too much erosion floorings, the steel plate after polishing should ensure that the smooth, clean of surface.
