Small-curvature-radius curve bridge pushing structure and pushing method
The invention relates to the technical field of bridge construction, in particular to a small-curvature-radius curve bridge pushing structure and a pushing method. Pushing devices are arranged on a temporary pier and a bridge pier. The pushing device comprises sliding rails fixed to the upper ends of the temporary pier and the pier. The sliding rail is a curved rail concentric with the arc-shapedmain beam, and a vertical jack is connected to the sliding rail in a sliding mode; horizontal jacks used for driving the vertical jacks to move along the sliding rails are arranged on the temporary pier and the pier. And the output end of the horizontal jack is hinged to the vertical jack. According to the bridge pushing structure, the problem that multiple times of deviation rectification are needed in traditional curved beam section pushing construction is solved, the pushing structure is extremely simple, the pushing construction efficiency is greatly improved, the bridge repairing and building cost and difficulty are greatly reduced, and the great popularization value is achieved.
本发明涉及桥梁施工技术领域，具体地指一种小曲率半径曲线桥梁顶推结构及顶推方法。所述临时墩和桥墩上设置有顶推装置；所述顶推装置包括固定在临时墩和桥墩上端的滑轨；所述滑轨为与弧形主梁同圆心的曲线轨道，滑轨上滑动连接有竖向千斤顶；所述临时墩和桥墩上设置有用于驱动竖向千斤顶沿滑轨移动的水平千斤顶；所述水平千斤顶的输出端铰接连接于竖向千斤顶。本发明的桥梁顶推结构解决了传统曲线梁段顶推施工需要进行多次纠偏的问题，且本发明的顶推结构极为简单，顶推施工效率大幅度提升，桥梁修造成本和难度大幅度降低，具有极大的推广价值。
