The present application relates to the technical field of ceramic coating, especially to a micro-nano structure ceramic coating and its application on the reaction furnace of zircon sand boiling chlorination method, aiming at solving the problems of weak bonding force between the existing protective coating and the substrate, poor thermal shock resistance and easy failure in long-term high-temperature chlorine environment; the present application constructs a nano-wire reinforced micro-nano structure transition layer on the surface of porous corundum brick substrate in situ, and sequentially constructs a lanthanum phosphate bonding layer and a yttrium stabilized zirconium oxide barrier layer on the transition layer; the design utilizes the mechanical anchoring effect of micro-nano structure and the strong chemical bonding ability of lanthanum phosphate to realize the firm combination of the coating and the substrate; the dense characteristics of the zirconium oxide layer provide ultimate protection; the method significantly improves the overall anti-peeling ability and long-term corrosion resistance of the coating system.

The road surface structure of the cross level crossing suitable for signal lamp control comprises a left hard road shoulder, an overtaking lane, a traffic lane and a right hard road shoulder, and the left hard road shoulder, the overtaking lane and the right hard road shoulder are all semi-rigid asphalt road surfaces; the traffic lane is characterized in that the traffic lane is a continuous reinforced concrete pavement at a brake road section which is 200-400m long close to the level crossing controlled by the signal lamp, a cement stabilized macadam base layer is arranged below the continuous reinforced concrete pavement, and an isolating layer is arranged between the continuous reinforced concrete pavement and the cement stabilized macadam base layer below the continuous reinforced concrete pavement. According to the road surface structure of the cross level crossing suitable for signal lamp control, the continuous reinforced concrete road surface has higher shear stress resistance and compressive stress resistance, so that ruts cannot be generated on a brake road section formed by the continuous reinforced concrete road surface when a vehicle brakes on the brake road section, the service life of the road is prolonged, and the traffic safety is improved. And the driving safety is ensured.
