description The utility model discloses a traffic tunnel portal protection structure which comprises a first protection unit and a second protection unit which are sequentially arranged at intervals from top to bottom along a hillside, the first protection unit is arranged at the bottom of a gully, and the first protection unit comprises a retaining wall and a drainage channel which are arranged on the hillside. The retaining wall and the drainage channel extend from the top of the traffic tunnel portal to the river-facing side of the hillside, the second protection unit comprises a shed tunnel and a reinforced gabion, the shed tunnel communicates with the traffic tunnel portal, and the reinforced gabion is arranged on the side, close to the retaining wall, of the shed tunnel. The protection device can protect flood and dangerous rock mass rolling stones at the same time, the protection safety coefficient is high, and meanwhile the reinforcing steel bar gabions can absorb the impact kinetic energy of the rolling stones t
