The present invention having the beneficial effect that compared with prior art

1, short construction period, methyl methacrylate road surface coating is as a kind of coating material, and speed of application is fast, according to one Individual teams and groups 5 individual calculus, can construct every day 500-1000m2

2, construction is simple, and the construction of methyl methacrylate road surface coating is not required to heavy mechanical equipment, with mini-plant is only Can meet requirement, construction is simple;

3, cost is low, methyl methacrylate road surface coating thickness 1mm-5mm, and thickness is much smaller than other road surface coatings Structure, unit are/1m2Cost only 150-200 unit;

4, durability is strong, and methyl methacrylate road surface coating durability is strong, and its life-span reaches more than 5 years;

5, easy to maintenance, road surface is once destroyed, and sprays MMA coating and can complete pavement maintenance at destruction after cleaning out Work.

Detailed description of the invention

Technical scheme in the embodiment of the present invention will be clearly and completely described below, it is clear that described enforcement Example is only a part of embodiment of the present invention rather than whole embodiments.Based on the embodiment in the present invention, this area is common The every other embodiment that technical staff is obtained under not making creative work premise, broadly falls into the model of present invention protection Enclose.

Embodiments provide the construction method of methyl methacrylate road surface coating, including:

S1 plate-girder roof handling:

Clear up plate-girder end face before construction and concrete laitance is carried out grinding process, after the concrete laitance polishing on surface, Cleaning laitance.

In this step, owing to methyl methacrylate coating layer thickness is less than 2.5mm, thinner thickness.Methyl methacrylate The substantially full backup plate top surface of the beam flatness of the flatness of ester is controlled, so plate-girder roof handling is the most important.Meanwhile, in order to protect Card methyl methacrylate coating is combined closely with bridge floor, needs to be cleaned out by plate-girder end face and enter concrete laitance before construction Row grinding process.The on-the-spot grinding apparatus used is two-sided polisher.After the concrete laitance polishing on surface, will be floating with aerator Slurry is cleaned out.

S2 priming coat roller coating:

Bridge floor cleaning, be dried without hydrops on the premise of, use cylinder to carry out slowly uniformly brushing along bridge floor, brushing completes Rear placement, dry in the sun are to being dried;

In this step, must assure that bridge floor cleaning before priming coat construction, be dried without hydrops.Priming coat claims transparency emulsion Shape, material is specialized factory's finished product material, it is not necessary to do any process, directly uses cylinder to brush along bridge floor during construction, brushing Time should be the most uniform, it is to avoid holiday.This priming coat acts primarily as waterproof, caulking joint and cementation.Placement, dry in the sun after having brushed 6h-12h is to being dried.

S3 methyl methacrylate coating is constructed:

Methyl methacrylate coating, based on methyl methacrylate material, is subsequently adding appropriate firming agent and solvent;

Priming coat carries out methyl methacrylate coating construction after drying, and this coating construction point two-layer is constructed, bottom Use the mode of blade coating, thickness 1-1.5mm;Surface layer uses the mode of spraying, thickness 1mm.

In this step, methyl methacrylate coating is according to methyl methacrylate: firming agent: solvent=50:1:1 ratio Example is prepared.

Operated by professional during bottom blade coating, methyl methacrylate coating be poured on bridge floor according to consumption, Workmen strikes off by floating rule feeding.

Bottom has been constructed and has been carried out the spraying application of surface layer after 2h, the uniformity of priority control spraying in work progress.Face Layer spraying uses spray gun to carry out, and notes protection adjacent structure thing, prevent from spraying on other adjacent structure things by mistake in spraying process.

S4 inspection of quality.

At present, there is no the inspection of quality specification of methyl methacrylate coating construction, be that " urban road is colored with reference to specification Asphalt concrete pavement technical regulation " in chapter 6 6.2.1-2 trifle bicycle lane pavement quality touchstone and permit Permitted deviation.Its dominant item colored, thickness and antiskid, general data has width, transverse slope and flatness.

Embodiments provide the construction method short construction period of methyl methacrylate road surface coating, construction letter Single, cost is low, and durability is strong, easy to maintenance.
