Construction process for seismic reinforcement of bridge supporting padstone
A construction technology for seismic strengthening of a bridge supporting padstone comprises the steps that after a beam is lifted, concrete around the original supporting padstone and concrete on the top of a peripheral beam are firstly subjected to chiseling treatment and cleaned up; and then a reinforcement cage is bound according to design requirements, steel plates with rivets are adopted to be fixed to the periphery of the reinforcement cage, steel plate joints are welded, finally, self-compacting concrete is poured, and beam falling is conducted after maintenance is conducted to design strength. Compared with traditional post-earthquake repair, the reinforcing operation is few in procedure steps, the needed time is shorter, the strength of the supporting padstone can be effectively enhanced, the bridge anti-seismic repair time and adverse effects caused by traffic interruption are reduced, and post-earthquake disaster relief and production and life recovery are facilitated.
一种桥梁支撑垫石抗震加固的施工工艺，升梁后首先对原有支撑垫石四周混凝土和周边梁顶混凝土进行凿毛处理，并清理干净；然后根据设计要求绑扎钢筋笼，采用带有锚钉的钢板固定在钢筋笼四周，钢板接头处焊接，最后浇筑自密实混凝土，养护到设计强度之后再落梁。相比于传统的震后修复来说，上述加固操作的工序步骤较少，所需的时间更短，能有效增强支撑垫石的强度，减少桥梁抗震修复时间和交通中断所带来的不利影响，有利于震后救灾和生产生活恢复。
