Pile foundation underpinning structure for new urban tunnel below bridge
The invention discloses a pile foundation underpinning structure for a new urban tunnel below a bridge. The structure comprises bridge piles, underpinning beams and underpinning piles, wherein the underpinning piles are arranged in two groups and located at the left sides and the right sides of the bridge piles respectively, the upper ends of the two groups of underpinning piles are fixedly connected with supporting crossbeams respectively, the upper end of each supporting crossbeam is fixedly connected with one group of cross-shaped supporting beams, multiple cross-shaped supporting beams arearranged in each group, the middle portions of the upper ends of every two cross-shaped supporting beams distributed in the same longitudinal direction are fixedly connected with a jacking mechanism,the upper end of each jacking mechanism is fixedly connected with a jacking plate, the upper end of each jacking plate is fixedly connected with a connecting block, and a first supporting longitudinal beam and a second supporting longitudinal beam are fixedly connected to the front portion and the rear portion of the upper end of each connecting block. Through the pile foundation underpinning structure for the new urban tunnel below the bridge, the supporting effect of the first supporting longitudinal beams and the second supporting longitudinal beams is improved, the underpinning effect isgood, and construction cost is low.
本发明公开了一种用于桥梁下方新建城市隧道的桩基托换结构，包括桥桩、托换梁和托换桩，所述托换桩设置有两组且分别位于桥桩的左侧和右侧，两组所述托换桩的上端均固定连接有支撑横梁，两个所述支撑横梁的上端均固定连接有一组十字支撑梁，每组所述十字支撑梁均设置有多个且分布在同一纵向方向上的两个所述十字支撑梁的上端中部均固定连接有顶升机构，所述顶升机构的上端固定连接有顶升板，所述顶升板的上端固定连接有连接块，所述连接块的上端前部和上端后部分别固定连接有一号支撑纵梁和二号支撑纵梁。本发明所述的一种用于桥梁下方新建城市隧道的桩基托换结构，提高了一号支撑纵梁和二号支撑纵梁的支撑效果，托换效果好，施工成本低。
