Integrated rainwater cross-cutting ditch structure for tunnel portal
The invention discloses an integrated rainwater cross-cutting ditch structure for a tunnel portal. First concrete layers are arranged on the two sides of a cross-cutting ditch respectively, first connecting ribs are arranged on the first concrete layers and anchored into a concrete floor, notches are formed in the tops of the first concrete layers, rainwater grates are arranged at the notches, second connecting ribs are reserved at the notches of the first concrete layers, and the first concrete layers are fixedly connected with the rainwater grates through the second connecting ribs. The wear resistance of concrete on the two sides of the cross-cutting ditch is improved, rolling damage is prevented, meanwhile, the side walls have a good supporting and blocking effect on pavement structure layers on the two sides, and local damage to the pavement structure layers is prevented; the phenomenon of vehicle jumping at the cross-cutting ditch is effectively reduced, the driving comfort is enhanced, meanwhile, damage to the cross-cutting ditch is reduced, and operation and management are facilitated.
本发明公开了一种隧道洞口一体化雨水横截沟构造，在横截沟的两侧分别设置有第一混凝土层，所述第一混凝土层上设置有第一连接筋，所述第一连接筋锚入混凝土地板中，所述第一混凝土层的顶部设置有槽口，所述槽口处设置有雨水箅子，所述第一混凝土层在所述槽口处预留有第二连接筋，所述第一混凝土层通过所述第二连接筋与所述雨水箅子固定连接。本发明不仅提高横截沟两侧混凝土耐磨性能，防止碾压损坏，同时侧壁对两边路面结构层起到了很好的支挡作用，防止该段路面结构层的局部损坏；还有效地减小了横截沟处跳车现象，增强了行车舒适性，同时减少了横截沟的损坏，便于运营管养。
