THE APPLICATION OF STEEL BOX GIRDER TOP PUSHING TECHNOLOGY IN THE CONSTRUCTION OF OVERPASS BRIDGES ON HIGHWAYS
In order to ensure the construction quality of highway overpass bridges,taking the example of the shapingdong interchange overpass of the tongxiu expressway project crossing the existing hangrui expressway,the steel box girder top pushing technology is studied.based on the actual situation of the project,design a steel box girder top pushing construction plan,select a 630 t walking type translational top pushing equipment,and complete the key process of top pushing construction according to the construction standards to complete the top pushing construction of the steel box girder.After analyzing the construction results,it was determined that the construction quality of this technology is good,and the calculation results of its anti overturning ability are all above 3,meeting the engineering standards.
