Bridge abutment disease treatment method for highway bridge crossing existing railway
The invention discloses an abutment disease treatment method for a highway bridge crossing an existing railway, which comprises the following steps of: in the treatment process, hoisting a bridge body of the highway bridge to the existing highway to be placed, dismantling partial abutment which has diseases and affects the safety of the existing railway, constructing a cross beam on a pile foundation, and utilizing the railway skylight time to construct the bridge abutment. And a prefabricated plate girder and the girder body are hoisted to the cross beam, the plate girder is located on the demolished bridge abutment, finally bridge deck pavement is constructed, and renovation of the damaged highway bridge is completed. According to the method, the pile foundation can be constructed before the bridge abutment is dismantled, operation of the highway bridge is not affected, when the bridge abutment is dismantled, only parts which have diseases and affect safety of an existing railway need to be dismantled, dismantling of the existing bridge abutment is reduced, meanwhile, excavation and backfilling of a roadbed behind the highway bridge abutment are reduced, the construction speed is increased, and the construction cost is reduced. The influence on passing of the highway bridge is small in the integration and renovation process, and investment can be saved by reducing dismantling of existing bridge abutments and bearing platforms.
本发明公开了一种跨越既有铁路的公路桥桥台病害整治方法，整治过程中先将公路桥的梁体吊至既有公路上放置，拆除具有病害且影响既有铁路安全的部分桥台，在所述桩基上施工横梁，利用铁路天窗时间，将预制的板梁和所述梁体吊至所述横梁上，所述板梁位于拆除的所述桥台上，最后施工桥面铺装，完成病害公路桥的整治。采用本发明的方法施工桩基可以在拆除桥台前施工，不影响公路桥的运行，拆除桥台时只需要拆除具有病害且影响既有铁路安全的部分，减少既有桥台拆除，同时减少公路桥台后路基的开挖和回填，加快了建设速度，整合整治过程中较小对公路桥通行的影响，减少既有桥台和承台拆除可以节约投资。
