Bridgehead bumping prevention structure suitable for large-width bridge
The invention discloses a bridgehead bumping prevention structure suitable for a large-width bridge, which comprises two bridgeheads with parallel gaps, bridge decks arranged on one sides of the bridgeheads, column piers for supporting the bridge decks, and concrete split walls arranged on one sides, far away from the bridge decks, of the gaps of the two bridgeheads, split wall connecting assemblies are arranged on the two sides of the concrete split wall and connected with one side of a reset reinforcing structure in the flexible soil body, and the other side of the reset reinforcing structure is connected with a force transmission plate. The concrete split wall is arranged at the bridgehead position of a large-width bridge, the flexible soil body is separated through the concrete split wall, meanwhile, supporting is provided for the two sets of reset reinforcing structures, and the weight load of the soil body needing to be borne by the single-side reset reinforcing structure is reduced. Through the hydraulic damper and the hinged jack, the reset reinforcing structure can be adjusted, and the reset reinforcing structure can be lifted in a loading mode after bumping occurs at the bridgehead.
本发明公开了一种适用于大宽度桥梁的防桥头跳车结构，包括间隙平行的两个桥头、设置在每个桥头一侧上的桥面板、支撑各桥面板的柱墩，两个桥头间隙远离桥面板的一侧设置有混凝土分体墙，所述混凝土分体墙两侧均设置有分体墙连接组件，所述分体墙连接组件与柔性土体内的复位加固结构一侧相连，复位加固结构另一侧与传力板相连。本发明针对大宽度桥梁在桥头位置设置混凝土分体墙，通过混凝土分体墙分隔柔性土体，同时为两组复位加固结构提供支撑，减少单侧复位加固结构需要承担土体的重量载荷。本发明通过液压阻尼器、铰接的千斤顶能够复位加固结构进行调节，能够在桥头跳车发生后，通过加载的方式提升复位加固结构。
