    • PROBLEM TO BE SOLVED: To provide a soundproof wall for a tunnel, which inexpensively enhances a soundproof effect without depending on an increase in weight.
      SOLUTION: This soundproof wall for the tunnel, which is installed in the pit of the tunnel T during excavation, is equipped with a reflecting section 2 which forms a reflecting surface 20 composed of a concavely-curved surface. The soundproof wall is also equipped with a switching member 3 for switching an attitude of the reflecting section 2 between a front attitude in which the reflecting surface 20 is directed to a cutting-face side, and a lateral attitude in which the reflecting surface 20 is directed to a side surface of the tunnel T.
