The invention discloses an anti-falling device for a water pipe in a tunnel, the anti-falling device comprises a fixed steel plate, a supporting structure arranged on the fixed steel plate and two connecting seats, warning structures are clamped in the two connecting seats, and the two warning structures are jointly connected with a limiting rope. When the fixing steel plate and the supporting structure are loosened due to the impact of air flow, the limiting cable pulls the warning structure in the connecting base to be separated to the outside due to the gravity action of the fixing steel plate and the supporting structure, so that the warning structure makes a sound under the impact of the air flow to prompt the maintenance position. And the limiting cable is fixed under the gravity of the fixing steel plate and the supporting structure and the traction of the connecting base after moving in the connecting base is finished so as to limit and support the fixing steel plate and the supporting ...
