Bridgehead bumping prevention structure suitable for small-width bridge and construction method of bridgehead bumping prevention structure
The structure comprises a bridge head, a reset reinforcing structure is arranged on the side, away from a bridge deck slab, of the bridge head, connecting structures crossing the bridge head are arranged on the two sides of the reset reinforcing structure, and loading structures for reset loading are arranged at the positions of the connecting structures; the construction method comprises the following steps that construction of the bridge deck slab, the bridge head and the column pier is completed; mounting a first steel connecting column sleeve and a second steel connecting column sleeve; the second steel connecting column sleeve is connected with the zigzag connecting plate and the inclined plate and is movably connected with the second steel connecting column sleeve; construction of a flexible soil body is conducted from bottom to top, and elevation construction is conducted to the lower bottom face of the lowest force transmission plate; the lowest force transmission plate is fixedly connected; fixedly connecting the expansion force holding plate, and laying the divergent reinforcing mesh; the flexible soil body on the side edge of the bridgehead continues to be constructed, and elevation construction is conducted to the lower bottom face of the next-stage force transmission plate; and the construction is repeated until completion. The construction period of the bumping problem at the bridgehead can be shortened, and the urban road passing convenience is improved.
本发明公开了一种适用于小宽度桥梁的防桥头跳车结构及其施工方法，其结构包括桥头，桥头远离桥面板的一侧布设有复位加固结构，复位加固结构两侧设置有跨越桥头的连接结构，连接结构处设置有进行复位加载的加载结构；其施工方法，包括以下步骤：完成桥面板、桥头、柱墩的施工；安装第一钢连接柱套、第二钢连接柱套；连接折形连接板、斜板，并与第二钢连接柱套活动相连；从下至上进行柔性土体的施工，标高施工至最低传力板下底面；固定连接最低传力板；固定连接扩展持力板，铺设发散型钢筋网片；继续桥头侧边柔性土体的施工，标高施工至下一级传力板下底面；重复施工直至完成。本发明能够缩短桥头跳车问题的施工周期，提高城市道路通行便利性。
