Guidance-type anti-falling-rock tunnel portal segment structure
The invention discloses a guidance-type anti-falling-rock tunnel portal segment structure. The structure comprises a concrete structure which is built close to the mountain, on the periphery of an open cut tunnel segment of a tunnel portal. The vertical cross section of the concrete structure is trapezoid, the top surface and two inclined side surfaces of the concrete structure are arc surfaces which are inwards sunken, and the sides, close to the mountain, of the top surface and side surfaces of the concrete structure are tangent to the slope of the mountain. The top and bottoms of the two side surfaces of the concrete structure are provided with supporting columns, and flexible protection nets are hung on the supporting columns and cover the top surface and two side surfaces of the concrete structure. According to the tunnel portal segment structure, a special protection structure is built outside a tunnel portal segment, the movement locus of falling rocks of the slope can be guided, so that the falling rocks automatically move towards the two sides away from the tunnel portal and roll to the safety zone, and the driving safety and structure safety of the tunnel portal segment can be guaranteed to the greatest extent.
本发明公开了一种可引导式防落石的隧道洞口段结构，包括在隧道洞口明洞段外围紧贴山体修建的混凝土结构，混凝土结构的竖直横截面呈梯形，混凝土结构的顶面和两个倾斜侧面均为向内凹陷的圆弧面，混凝土结构顶面和侧面靠近山体的一侧均与山体坡面相切，混凝土结构的顶部以及两侧面的底部上均安装有支撑柱，支撑柱上挂设有柔性防护网，柔性防护网覆盖在混凝土结构的顶面和两侧面的上方。本发明的隧道洞口段结构，通过在隧道洞口段外部修建特殊的防护结构，能够引导坡面落石的运动轨迹自然向远离隧道洞口的两侧进行运动，使落石滚落至安全地带，可以最大程度的保障隧道洞口段的行驶安全和结构安全。
