description The utility model discloses a tunnel pre-reinforcing structure which comprises a tunnel body and an outer supporting body arranged on the outer side of the tunnel body, and a reinforcing frame used for reinforcing and supporting the top end of the outer supporting body is arranged between the tunnel body and the outer supporting body. A plurality of pre-reinforcing columns distributed at equal intervals are arranged at the bottom of the outer supporting body in the length direction of the outer supporting body, and the reinforcing frame comprises an upper fixing plate fixedly connected with the inner wall of the top end of the outer supporting body. According to the tunnel pre-reinforcing structure, through cooperation of the upper fixing plate, the reinforcing plate, the first supporting steel plate, the inclined supporting steel plate and the second supporting steel plate, a plurality of small-size supporting structures are formed between the reinforcing frame and the outer supporting body, and the firmness
