Bridge-on-bridge reinforcing method based on old bridge piers
The invention provides a bridge-on-bridge reinforcing method based on old bridge piers, which comprises the following steps: S10, longitudinally arranging Bailey beams on an original bridge, respectively arranging supporting structures at the two end parts of the original bridge and the suspended position of the original bridge, and supporting the Bailey beams by the original bridge through the supporting structures; s20, transversely laying a plurality of cross beams on the top surface of the bailey beam, wherein the length of the cross beams corresponds to the width of the original bridge; s30, steel panels are laid on the cross beams; and S40, ramps are arranged on the two sides of the steel panel correspondingly, and the steel panel is connected with the road through the ramps. The construction speed is high, construction is easy and convenient, investment is small, the new bridge is erected on the basis of the original bridge structure, the load transmission structure is arranged between the original bridge and the new bridge structure, the original bridge shares part of vehicle loads, the manufacturing cost of the new bridge can be reduced, and the overall bearing capacity limit value of the bridge-on-bridge structure can be increased.
本发明提供了一种基于旧桥桥墩的桥上桥加固方法，包括以下步骤：S10、纵向在原桥梁上设置贝雷梁，在原桥梁两端部位置、原桥梁悬空位置分别设置支撑结构，原桥梁通过支撑结构对贝雷梁支撑；S20、横向在贝雷梁顶面铺设若干横梁，横梁长度和原桥梁的宽度对应；S30、在横梁上铺设钢面板；S40、在钢面板两侧分别设置坡道，通过坡道将钢面板和道路连接。本发明施工速度快、施工简便、投资少，新桥架设在原桥结构基础上进行，在原桥与新桥梁结构之间设置荷载传递结构，让原桥分担一部分车辆荷载，既能降低新桥的造价，又能提高“桥上桥“结构整体的承载能力极限值。
