Limiting device for anti-overturning and anti-pulling reinforcement of bridge and construction method thereof
The invention relates to the technical field of bridge anti-overturning and anti-pulling reinforcement, in particular to a limiting device for bridge anti-overturning and anti-pulling reinforcement and a construction method thereof. The problems that in the prior art, a bridge single-column pier anti-overturning reinforcing method is large in construction difficulty, high in reinforcing cost and long in construction period, and no good solution is provided for curved bridge creeping and continuous steel beam bridge side span upwarp are solved. According to the technical scheme, the device comprises a first bottom steel plate connected with a main beam and a second bottom steel plate connected with an abutment, a pair of channel steel is symmetrically welded to the lower portion of the first bottom steel plate, I-shaped steel is vertically welded to the second bottom steel plate and arranged between the pair of channel steel, and a pi-shaped steel baffle is arranged at the bottom of the I-shaped steel. The pi-shaped steel baffle is welded on the pair of channel steel; and the main beam is of a reinforced concrete structure or a steel structure.
本发明涉及桥梁抗倾覆及抗拔加固技术领域，具体涉及一种桥梁抗倾覆及抗拔加固的限位装置及其施工方法。针对现有技术中桥梁独柱墩抗倾覆加固方法中施工难度大、加固成本高、施工工期长的问题，以及曲线桥爬移、连续钢梁桥边跨上翘这类没有较好的解决方案的问题。本发明所采用的技术方案包括与主梁连接的底钢板一和与墩台连接的底钢板二，底钢板一下部对称焊接有一对槽钢，所述的底钢板二上垂直焊接有工字钢，工字钢设置于一对槽钢之间，工字钢底部设置有π型钢挡板，π型钢挡板焊接于一对槽钢上；所述的主梁为钢筋混凝土结构或钢结构。
