Study on Construction Technology of Steel Suspension Box for Base Slab of Yongning Bridge
By considering the hydrogeological and other natural factors of Feiyun River in Wenzhou,the construction technology of base slab for Z02#～Z08# piers of Yongning Bridge in Wenzhou is studied.The single-wall steel suspension box is sued as the water blocking structure for the construction of base slab.The structural design is carried out for the steel suspension box.Combined with factors of high precision of steel suspension box assembly,lowering and installation during on-site construction,high construction safety risks,and harsh environment,a complete set of lowering,detachable and recyclable steel suspension box construction system for base slab is formed,which accelerates the construction progress and reduces the construction costs,and has a certain reference significance for the construction of water base slab of bridge engineering in the future.
