Embodiment Construction
[0026] Such as figure 1 and figure 2 As shown, the railway tunnel exit partition plate type buffer structure designed by the present invention has a type box 2 respectively arranged on both sides of the tunnel exit 6, and the side wall of the type box 2 close to the center line of the tunnel 1 is an opening surface 3; The box 2 is provided with a first partition 4 parallel to the opening surface 3, and the two ends of the first partition 4 are fixedly connected to the top surface and the bottom surface of the mold box 2, and the same mold box 2 The sum of the areas of the first partition 4 is less than the area of the opening surface 3 of the mold box 2; and the second partition 5 connected with the first partition 4, the second partition 5 stretches into the mold box 2 . The area mentioned here means that the first separator 4 is regarded as a surface with a thickness of 0, just like the opening surface 3 . Preferably, the area of the first partition 4 at the same mol...
