Bridge abutment underpinning reinforced bridge structure and construction method thereof
The invention discloses an abutment underpinning reinforcing type bridge structure which comprises an original main beam, a first original abutment, a second original abutment, a newly-built main beam, a newly-built abutment and a newly-added reinforcing assembly. The outer end of the original main beam is supported at the top of the first original bridge abutment; the inner end of the original main beam is aligned with the inner end of the newly-built main beam; the outer end of the newly-built main beam is supported on the newly-built bridge abutment; a reinforcing assembly is additionally arranged at the position of the second original bridge abutment, the bottom of a reinforcing pile of the reinforcing assembly is located on the underground bearing layer, the reinforcing assembly and the second original bridge abutment form a reformed reinforcing pier, and the top of the reformed reinforcing pier supports the inner ends of the original main beam and the newly-built main beam. The bridge structure and the construction method have the beneficial effects that the original bridge abutment structure is not changed, the newly-added reinforcing assemblies, the newly-added bridge abutment and the newly-added main beam are additionally arranged in front of and behind the original foundation, and the bridge structure and the construction method solve the problem of insufficient bearing capacity caused by bridge abutment body cracking and differential settlement.
本发明公开了一种桥台托换加固式桥梁结构，包括原主梁、第一原桥台、第二原桥台、新建主梁、新建桥台和新增加固组件；所述原主梁的外端支撑于第一原桥台的顶部；所述原主梁的内端与新建主梁的内端对齐；所述新建主梁的外端支撑于新建桥台上；所述第二原桥台处新增加固组件，新增加固组件的加固桩桩底位于地下持力层，新增加固组件与第二原桥台组成改造加固桥墩，改造加固桥墩的顶部支撑原主梁和新建主梁的内端。本发明的有益效果为：本发明不变动原桥台结构，在原基础前后增加新增加固组件、新增桥台和新建主梁，这种桥梁结构及施工方法解决了由于桥台台身开裂及不均匀沉降带来的承载力不足的问题。
