Analysis on Pile Sinking Efficiency of Full Turning Piling Barge
Yongning Bridge Project in Wenzhou Municipal Railway S3 Line Auxiliary Supporting Project(Ruian Section)is a composite special bridge integrating the functions of municipal railway,expressway,first-class highway,slow travel system etc.,which is a double-deck bridge.Its main bridge spanning Feiyun River is designed as a rigidity suspension bridge with a main span of 260 m.There are 7 piers designed in water.The pile foundation steel casing and steel pipe piles are all driven by the full-turning pile barge"Haili 801".By analyzing the pile sinking efficiency of the steel casing and steel pipe piles of Yongning Bridge,the relevant experience is summarized,which provides reference for the subsequent pile sinking construction of offshore and cross-river bridge projects.
