In the traffic construction of China, most of bearing structures (culverts, tunnels and tunnel portal protection structures) adopt common reinforced concrete or masonry structures, and the structures are easy to crack, seep water, expose ribs and other diseases in the later period. The concrete open cut tunnel structure commonly used for the tunnel portal has large volume and heavy weight, and is not beneficial to site construction. In the construction of facilities for large temporary facilities of railways, the construction of access roads and access bridges has long construction period and high construction cost. In addition, in some emergency rescue projects, the construction period of the cast-in-place concrete is long, and the emergency rescue requirements cannot be met, so that the use of the concrete structure in the projects is also restricted.
In view of this, a quick, economical, convenient form of corrugated plate structure is applied to the above-mentioned railway works. However, the main material of the corrugated pipe (plate) structure is steel, so that the durability of the corrugated pipe (plate) structure is an important factor influencing popularization and use. The corrugated pipe (plate) structure is eroded by atmosphere, soil and underground water, so that it must be treated with anticorrosion treatment as common steel pipe, and can prolong the service life of the corrugated pipe (plate) structure.
In the existing corrugated plate anticorrosion method which is commonly used in recent years, the hardness of an aluminum coating on the surface is not enough, so that the aluminum coating is often damaged due to scratch in the construction process; acid pickling and rust removal of hot dip galvanizing of the hot dip galvanizing layer can leave hidden troubles for corrosion prevention. In addition, the galvanizing technology pollutes the environment; problems of peeling or cracking also occur when applying polymer coatings because of insufficient hardness and insufficient permeation resistance. The powder galvanizing process is mature, the formed anticorrosive coating has good uniformity and continuity and high strength, the coating is difficult to peel off, and the wear resistance and scratch resistance are strong. Especially suitable for various environments such as marine atmosphere, severe industrial atmosphere and the like, and the corrosion resistance is superior to that of hot-dip galvanizing and electrogalvanizing. Can resist high-temperature oxidation corrosion of less than 1000 ℃.
