通车条件下桥梁支座更换

Bridge Bearing Replacement on Condition of Open-traffic

桥梁在使用过程中,由于设计原因、施工原因或者使用年限原因等,一些橡胶支座会发生不同程度的损坏或者老化。如果公路交通比较繁忙,就必须考虑在通车条件下对支座进行更换,结合施工实例,采用自锁式扁平型液压千斤顶同步顶升更换支座。

Due to the reasons such as design,contraction or service life,some rubber bearings will be damaged or aging in different degree during the use of bridge. When the traffic is busy,it must be considered to replace the bearings on the open-traffic condition. Base on the of site practice,this paper introduced bearing replacement through synchronization of self-locking flattened hydraulic jacking up.
