NOVELTY - The method involves connecting a top side of a mobile platform (2) with a grinding component for polishing an inner wall of a side of tunnel (1). A side of wind- shield (5) is provided with a dust removing assembly for removing dust on an inner side wall of the tunnel. A top end of the mobile platform is connected with a spraying assembly for spraying primer on the inner wall on the side of the tunnel. A bottom surface of a base surface is fixed on the surface of the base surface. A surface is cleaned according to the surface. The grinding assembly is provided with a cavity. A bottom inner wall of the cavity is fixedly connected with a driving motor. A side of the grinding table (9) close to the tunnel is fixedly connected with a fixing ring. USE - Coating graphene anti-seepage coating construction method. ADVANTAGE - The method enables automatically polishing the inner wall of the tunnel, thus ensuring the stability of the spraying and after spraying the tunnel inner wall surface of the flat and beautiful. The method ensures the smooth and beautiful surface after construction, thus cleaning, drying, and no pollutant. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic diagram of the tunnel. 1Tunnel 2Mobile station 4Track 5Wind screen 10Primer box 47Baffle 48Camera
