Highway bridgehead bumping prevention and treatment structure and construction method
The invention relates to the technical field of bridgehead structures, in particular to a highway bridgehead bumping prevention and treatment structure which comprises a bridge body section and a roadbed section. A transition area is reserved between the bridge body section and the roadbed section, a transition section is arranged in the transition area, and the transition section comprises a transition table with the two ends connected with the bridge body section and the roadbed section respectively. The transition table comprises a plurality of prefabricated concrete slabs arranged in the length direction of the bridge body section, any two adjacent prefabricated concrete slabs are connected through a connecting steel bar, a plurality of supporting pieces are arranged below each prefabricated concrete slab, and a concrete surface layer is arranged on the upper surface of the transition table. The method has the effect of improving secondary bumping caused by sudden change of pavement settlement.
本申请涉及一种公路桥头跳车的防治结构，涉及桥头结构的技术领域，其包括桥体段和路基段，桥体段与路基段之间预留有过渡区，过渡区内设置有过渡段，过渡段包括两端分别与桥体段和路基段连接的过渡台，过渡台包括若干件沿桥体段长度方向排布的预制混凝土板，任意相邻设置的两件预制混凝土板之间利用连接钢筋连接，各预制混凝土板的下方均设置有若干根支撑件，过渡台的上表面设置有混凝土面层。本申请具有改善路面沉降突变而导致二次跳车发生的效果。
