Patent CN110577798A discloses an energy-storing, light-emitting and self-cleaning water-based paint special for highway tunnels, wherein translucent hollow glass beads added in the paint can diffuse light to a certain extent, so as to reduce glare. CN101372598B discloses an energy-storage self-luminous road marking paint, which improves the overall light reflection performance of the paint by adding glass beads into an energy-storage luminous material.

In a preferred embodiment of the present invention, a binder is attached to the edge of the base layer. The edge pressing can be made of the same material as the base layer or different materials, and preferably, the edge pressing is made of ceramic fiber cloth. After the reflective cloth is attached to the wall surface through the back adhesive layer, the air flow and other environmental factors in the tunnel change to possibly cause the back adhesive layer to age gradually or lose efficacy, so that the reflective cloth falls off. In order to further improve the stability of the fixation of the reflective cloth, the edge of the reflective cloth is connected with a blank holder, the blank holder is fixed on the wall surface by a fastener to form installation fixation, so that the reflective cloth is still fixed on the wall surface after the gum fails, the potential safety hazard is reduced, a worker can check the bonding state of the reflective cloth during the periodic maintenance of the tunnel, and the reflective cloth which fails is replaced in time.

the carrying device comprises a main body, wherein two clamping grooves are formed in the main body and used for clamping the end part, the edge pressing or the clamping block of the reflective cloth.

The shape of the main body of the mounting device is set according to the wall surface of the tunnel. For a straight wall surface, the carrying device is of a vertical rod-shaped or tubular structure, and one side of the carrying device facing the wall surface is attached to the wall surface; for the arc-shaped wall surface, the carrying device is integrally of an arc-shaped rod-shaped or tubular structure, and one side of the carrying device facing the wall surface is attached to the wall surface. In a use state, a section of complete reflective cloth is arranged between two adjacent carrying devices. Be provided with two draw-in grooves in the main part, two draw-in grooves symmetry set up, and every draw-in groove is used for the one end of centre gripping reflection of light cloth so that reflection of light cloth can expand between two carrying devices. In some embodiments, the distance between two adjacent carrying devices is slightly less than the length of the reflective cloth, so that the reflective cloth is not completely unfolded when being installed, but is in a loose state with a certain deformation space, so that the reflective cloth can be deformed or even swung after the gum fails, and therefore when the air flows on the reflective surface, the swinging of the reflective cloth can be detected through the range finder, and then the alarm is given to the working personnel so as to maintain the corresponding reflective cloth in time.
