Design and Construction Technology of Reusable Steel Suspension Box for Water Base Slab
Yongning Bridge Project in Wenzhou Municipal Railway S3 Line Auxiliary Supporting Project(Ruian Section)is a composite grand bridge integrating the functions of municipal railway,expressway,first-class highway,slow travel system etc.,and is a double-deck bridge,in which the main bridge spanning the Feiyun River is designed of a rigidity suspension bridge with 260-m main span,and there are 7 piers(Z02～Z08)in the water.All are constructed with bottom steel suspension boxes.Because of its similar size of base slab structrues,after the analysis,comparison and screening of several construction schemes,the design concept of"reusable steel suspension box"is innovatively proposed and is successfully implemented in the Yongning Bridge Project.Under the condition of ensuring the construction period,the steel box suspension structure can be fully reused by this technology,which effectively saves costs and increases benefits,and can provide relevant experience for subsequent water bridge construction.
