Bridgehead roadbed reinforcing structure
The invention discloses a bridgehead roadbed reinforcing structure which comprises a supporting bridge column, a bridge abutment supporting column, bridge column bases, and a rock soil layer. A horizontal bridge frame is arranged above the supporting bridge column and connected with the supporting bridge column through reinforcing steel bars, a rubber damping support is arranged above the bridge abutment supporting column and connected with the bridge abutment supporting column through bolts, an approach bridge frame is arranged above the rubber damping support, the rubber damping support is connected with the approach bridge frame and the horizontal bridge frame in an attached mode, the bridge column bases are arranged at the bottom of the supporting bridge column and the bottom of the bridge abutment supporting column, a limiting shaft disc is arranged at the top of the bridge column base, and the bridge column base is connected with the supporting bridge column and the bridge abutment supporting column through the limiting shaft disc. The bridge column bases are connected through prefabricated hollow steel pipes, and a gravel soil layer is arranged above the rock soil layer. Reinforcing work of a bridgehead roadbed is achieved, and therefore a problem of high-low dislocation deviation, caused by environmental factors, of a butt joint position of a bridgehead and a highway approach bridge is solved.
本发明公开了一种桥头路基加固结构，包括：支撑桥柱，所述支撑桥柱的上方设置有水平桥架，且水平桥架与支撑桥柱通过钢筋连接，桥台支柱，所述桥台支柱的上方设置有橡胶减震支座，且橡胶减震支座与桥台支柱通过螺栓连接，所述橡胶减震支座的上方设置有引道桥架，且橡胶减震支座与引道桥架和水平桥架贴合连接，桥柱基座，其设置在支撑桥柱和桥台支柱的底部，所述桥柱基座的顶部设置有限位轴盘，且桥柱基座通过限位轴盘与支撑桥柱和桥台支柱连接，所述桥柱基座之间通过预制空心钢管连接，岩石土层，所述岩石土层的上方设置有碎石土层。其实现了对桥头路基的加固工作，从而保障桥头与公路引桥对接处不会受环境因素导致的高低错位偏差的问题。
