Anti-seismic strengthening type bridge abutment improved structure
The invention relates to an anti-seismic strengthening type bridge abutment improved structure. The anti-seismic strengthening type bridge abutment improved structure comprises a bridge abutment base body, a bearing beam is connected to the bridge abutment base body, a bridge abutment join assembly is arranged on the bearing beam, and bearing grooves are distributed in the bridge abutment join assembly. The anti-seismic strengthening type bridge abutment improved structure is characterized in that the periphery of the bridge abutment join assembly is connected with a strengthening structural part through join and location assemblies, one side of the bridge abutment join assembly is connected with an anti-seismic connection assembly through join and location assemblies, a buffering structure is arranged at the top end of the bridge abutment join assembly, and sliding layers are arranged in the bearing grooves. Therefore, by means of participation of the strengthening structural part, the firmness of an original old bridge abutment particularly the bridge abutment join assembly is improved. Meanwhile, as anti-seismic bolts are adopted as the join and location assemblies, while the fixed connection requirement is met, external vibration stress possibly occurring can be dissipated. Depending on the match of the buffering structure and the sliding layers, when impacted by huge vibration, the bridge abutment improved structure is allowed to shift safely within a certain range to dissipate the vibration stress. Moreover, the anti-seismic capacity is comprehensively promoted without increasing the structure section of an existing old bridge, and construction is convenient.
