Bridge abutment deviation rectifying and reinforcing structure and construction method thereof
The invention relates to the technical field of building deviation rectification, in particular to a bridge abutment deviation rectification reinforcing structure and a construction method thereof. The bridge abutment deviation rectifying and reinforcing structure comprises a plurality of rows of pre-stressed anchor cables which are arranged in the length direction of a bridge abutment and a retaining wall and on the side opposite to the inclined direction of the bridge abutment and used for reinforcing the bridge abutment and the retaining wall. At least one row of reinforcing anchor cables are horizontally and oppositely arranged in the length direction of the top of the retaining wall and penetrate through the abutment body, and the reinforcing anchor cables are used for preventing the abutment body from inclining towards the abutment back side; the dowel bars penetrate through the retaining wall and abut against the abutment body, the bearing platform and the bearing platform lower pile respectively, and at least one row of dowel bars are arranged in the length direction of the retaining wall; the pushing device is arranged at the exposed end, located on the retaining wall, of the dowel bar and used for applying pressure to the dowel bar. The pre-stressed anchor cables are arranged on the side opposite to the inclined side of the abutment to reinforce the abutment and the retaining wall; a dowel bar is arranged between the retaining wall and the abutment, and a pushing device is used for providing counter force to apply load to the dowel bar to push the abutment to tilt back.
本发明涉及建筑物纠偏技术领域，尤其涉及一种桥台纠偏加固结构及其施工方法。所述桥台纠偏加固结构包括预应力锚索，沿桥台及挡土墙的长度方向且向桥台倾斜相反的一侧布设有多排，用于加固桥台及挡土墙；加固锚索，沿挡土墙顶部的长度方向水平对穿桥台台身地布设有至少一排，用于防止桥台台身向台背侧倾斜；传力杆，穿透挡土墙分别与桥台台身、承台和承台下桩抵接，传力杆沿挡土墙的长度方向至少设有一排；顶推装置，设于传力杆位于挡土墙的露出端，用于对传力杆施加压力。本发明在桥台倾斜相反的一侧进行预应力锚索加固桥台及挡土墙；在挡土墙与桥台之间施作传力杆，利用顶推装置提供反力给传力杆施加载荷顶推桥台回倾。
