Construction method of structure for preventing bumping at bridge head
The invention discloses a construction method of a structure for preventing bumping at a bridgehead. The construction method comprises the steps of roadbed treatment, installation of prestressed tendons, installation of a butt strap support and a butt strap rear beam, installation of a left side plate and a right side plate, installation of a water bag body, installation of a butt strap, water filling of the water bag body, stretching of the prestressed tendons and pavement construction. When settlement of a roadbed transition section is found through reading of a pressure data acquisition instrument or visual inspection in the later period, the height of the water bag body is adjusted in the mode that the water bag body is filled with water through the water filling and discharging system, the top of the water bag body is made to make contact with the bottom face of the transition slab all the time, and the water bag body provides supporting force for the transition slab; the support obtained by the transition slab is adjusted in time, the transition slab is prevented from being broken due to disengagement, and the bumping phenomenon at the bridgehead is relieved.
本发明公开了一种防治桥头跳车结构的施工方法，包括路基处理、安装预应力筋、安装搭板支座和搭板后梁、安装左侧板和右侧板、安装水囊体、安装搭板、水囊体充水和预应力筋拉伸以及路面施工步骤。施工方法制作出防治桥头跳车结构，后期通过压力数据采集仪读数或目视法巡查发现路基过渡段发生沉降时，通过充放水系统往水囊体充水的方式调整水囊体的高度，使水囊体的顶部始终与搭板的底面接触，水囊体给搭板提供支撑力，及时调整搭板所得到的支撑，防止搭板脱空而断裂，减缓桥头跳车现象。
