Transition section connecting structure at junction of tunnel roadbed and highway roadbed
The invention relates to a transition section connecting structure at the junction of a tunnel roadbed and a highway roadbed, and belongs to the technical field of tunnel construction. The transition section connecting structure comprises: the tunnel roadbed which sequentially comprises a concrete cushion layer, a U-shaped groove bottom plate, a concrete filling layer and an asphalt pavement layer from bottom to top; the highway subgrade sequentially comprising a backfill layer and an asphalt pavement layer from bottom to top, wherein the backfill layer is flush with the concrete filling layer; and a reinforced concrete plate located at the bottom of the backfill layer and extending towards the tunnel roadbed, wherein the reinforced concrete plate and the U-shaped groove bottom plate are of an integrated pouring forming structure. According to the reinforced concrete plate, the structural stability between the tunnel subgrade and the highway subgrade is improved, the vertical rigidity of the highway subgrade is improved, and differential settlement of the tunnel subgrade and the highway subgrade is reduced. Load of the highway subgrade can be effectively transmitted to the reinforced concrete plate, so that the reinforced concrete plate and the tunnel subgrade bear the load together, uneven settlement at a boundary is avoided, and driving safety and comfort are improved.
本申请涉及一种隧道路基与公路路基交界处的过渡段连接结构，属于隧道施工技术领域，包括：隧道路基，其由下至上依次包括混凝土垫层、U形槽底板和混凝土填充层和沥青铺装层；公路路基，其由下至上依次包括回填层和沥青铺装层，回填层与混凝土填充层齐平；钢筋混泥土板，其位于回填层的底部且向隧道路基方向延伸，且与U形槽底板为一体式浇筑成型结构。本申请的钢筋混泥土板增加了隧道路基与公路路基之间的结构稳定性，又增加了公路路基的竖向刚度，减小了隧道路基与公路路基不均匀沉降。本申请能有效将公路路基的荷载传递给钢筋混泥土板，从而使钢筋混泥土板和隧道路基共同承受荷载，避免了分界处出现不均匀沉降，提高了行车安全和舒适性。
