    • PROBLEM TO BE SOLVED: To provide a sound insulating wall for a tunnel improving a sound insulating effect, and a sound insulating system for the tunnel using the sound insulating wall.
      SOLUTION: The sound insulating wall for the tunnel is installed in a pit of the tunnel T under excavation. In the sound insulating wall, a main reflecting part 2 having a main reflecting surface 20 formed of a concave surface is disposed at the center part in the pit separately from each wall surface of the tunnel T. An upper auxiliary reflecting part 3 formed with an auxiliary reflecting surface 30 of the same curved surface as the main reflecting surface 20 is disposed in a clearance S1 between the upper end of the main reflecting part 2 and the ceiling wall surface of the tunnel T. Side auxiliary reflecting parts 4 formed with auxiliary reflecting surfaces 40 of the same curved surfaces as the main reflecting surface 20 are disposed in clearances S2 between both right and left ends of the main reflecting part 2 and each side wall surface of the tunnel T.

    • PROBLEM TO BE SOLVED: To provide a soundproof house for a tunnel with improved sound insulating properties.
      SOLUTION: This soundproof house for a tunnel is installed at the front of the mouth 90 of the tunnel T for preventing noise from occurring during the construction of the tunnel T. A front wall part 10 positioned on the opposite side of the mouth 90, both left and right wall parts 12L, 12R positioned on both left and right sides of the front wall part 10, and a ceiling part 13 positioned over the front wall part 10 and the both left and right wall parts 12L, 12R are formed of sound insulating walls 16, respectively. The ceiling part 13 and both left and right wall parts 12L, 12R are connected to each other in a break point-free continuous concave when viewed from the inside of the house.
