| Abstract: | Taking interchange rubber plate with a reaction force adjustment as an example,the paper is to introduce continuous beam bridge to use steel structure as scaffold platform when rubber bearings hanging in the air or bearing shifted,changes of deck cross slope,beam body occurring displacement,and on the platform,set slid,top up(shift) beam jack,using ordered rising of jack to conduct righting,pan,adjustable slope elevation,consolidation,replacement of bearings and fallen beam in place for beam body,so that on the beam is situated in the design position step by step,in order to restore normal use of bridge. |
