Description

Technical Field

[0001] The invention relates to the technical field of coating spraying, and in particular to a graphene coating anti-seepage coating construction method for tunnels. Background Art

[0002] The problems that have arisen after the existing tunnel coating is opened to traffic are as follows: 1. The base powder appears in the uncoated tunnel, and the tunnel environment is darker: 2. The brightness of the tunnel painted with ordinary paint is not obvious, it is easy to be polluted, easy to mold, turn yellow, difficult to clean, and has a short service life: 3. The tunnel decorated with tiles will reflect light, glare, light shadows, etc., which will affect the vision and pose certain safety hazards, and the labor cost is high: 4. The decorative board tunnel is fragile, easy to be polluted, has a short service life, low cost performance and is not easy to clean. The use of special primers can effectively solve the problem of concrete surface powdering and can improve the overall compressive strength after curing: the use of graphene and functional nanomaterials can isolate the effect of corrosion, make the coating tightly connected, and increase the life of the finished coating, thereby reducing the repair and cleaning of the later operation and effectively reducing the maintenance pressure.

[0003] In the existing spraying process, for example, the invention with announcement number CN108686855B directly sprays the tunnel wall automatically through a nozzle, and another invention with announcement number CN206325744U directly sprays through a handheld airless spray gun.

[0004] However, there are still the following deficiencies in the spraying process:

[0005] 1. Since the tunnel is through, there is wind flow in the tunnel. During the process of spraying paint through the spray gun, the wind in the tunnel blows the sprayed paint to one side, causing the paint spraying position to deviate, repeated spraying, and uneven spraying thickness;

[0006] The tunnel wall cannot be automatically cleaned during spraying, and there are oil, moisture, dust and other dirt on the tunnel wall surface. Therefore, the tunnel surface is uneven after spraying, resulting in insufficient adhesion and compatibility between the base surface and the coating, affecting the smoothness and beauty of the surface after construction. Summary of the invention

[0007] The purpose of the present invention is to solve the problem in the prior art that the wind in the tunnel blows the sprayed paint to one side, making it impossible to automatically clean the tunnel wall, and to propose a compact graphene paint anti-seepage coating construction method for tunnels.
