Incremental launching construction method for bridge with small curvature radius
The invention discloses an incremental launching construction method for a small-curvature-radius bridge. Comprising the steps that firstly, a widening platform is arranged at the top of a bridge pier; secondly, a beam support and pushing equipment are installed; thirdly, the pushing direction of the small-curvature-radius bridge and the pushing speed of the pushing equipment are preset; 4, pre-pushing the bridge with the small curvature radius, and recording offset data; 5, rectifying and pushing the bridge with the small curvature radius; and 6, falling the bridge. The pushing process of the small-curvature-radius bridge body is completed through mutual cooperation of transverse pushing and longitudinal pushing, the construction period of the small-curvature-radius bridge is greatly shortened, the construction cost is reduced, compared with differential pushing and constant-speed pushing, the safety is high, and after pushing is completed, the construction efficiency is improved. And the deviation between the actual beam body position and the planned beam body position is small.
本发明公开了一种小曲率半径桥梁的顶推施工方法。包括步骤一、在桥墩顶部设置加宽平台：步骤二、安装梁支座和顶推设备：步骤三、预设小曲率半径桥梁的顶推方向以及顶推设备的顶推速度；步骤四、对小曲率半径桥梁进行预顶推，并记录偏移数据：步骤五、对小曲率半径桥梁进行纠偏以及顶推：步骤六、落梁。本发明对于小曲率半径桥梁梁体的顶推是通过横向顶推与纵向顶推相互配合完成顶推的过程，极大地缩短了小曲率半径桥梁施工工期，降低了施工成本，相较于差速顶推以及等速顶推，安全性强，顶推完成后，实际梁体的位置与规划梁体的位置偏差小。
